Cremation is the combustion, vaporization, and oxidation of cadavers to basic chemical compounds, such as gases, ashes and mineral fragments retaining the appearance of dry bone. Cremation may serve as a funeral or post-funeral rite as an alternative to the interment of an intact dead body in a coffin or casket. Cremated remains (also known as "cremains" or simply "ashes"), which do not constitute a health risk, may be buried or interred in memorial sites or cemeteries, or they may be retained by relatives and dispersed in various ways. Cremation is an alternative in place of burial or other forms of disposal in funeral practices. Some families prefer to have the deceased present at the funeral with cremation to follow; others prefer that the cremation occur prior to the funeral or memorial service.
In many countries, cremation is usually done in a crematorium. Some countries, such as India and Nepal, prefer different methods, such as open-air cremation.
Alternative death rituals emphasizing one method of disposal of a body—inhumation (burial), cremation, or exposure—have gone through periods of preference throughout history.
In the Middle East and Europe, both burial and cremation are evident in the archaeological record in the Neolithic era. Cultural groups had their own preferences and prohibitions. The ancient Egyptians developed an intricate transmigration-of-soul theology, which prohibited cremation. This was also widely adopted by Semitic peoples. The Babylonians, according to Herodotus, embalmed their dead. Early Persians practiced cremation, but this became prohibited during the Zoroastrian Period. Phoenicians practiced both cremation and burial. From the Cycladic civilisation in 3000 BCE until the Sub-Mycenaean era in 1200–1100 BCE, Greeks practiced inhumation. Cremation appeared around the 12th century BCE, constituting a new practice of burial, probably influenced by Anatolia. Until the Christian era, when inhumation again became the only burial practice, both combustion and inhumation had been practiced, depending on the era and location. Romans practiced both, with cremation generally associated with military honors.
In Europe, there are traces of cremation dating to the Early Bronze Age (c. 2000 BCE) in the Pannonian Plain and along the middle Danube. The custom became dominant throughout Bronze Age Europe with the Urnfield culture (from c. 1300 BCE). In the Iron Age, inhumation again becomes more common, but cremation persisted in the Villanovan culture and elsewhere. Homer's account of Patroclus' burial describes cremation with subsequent burial in a tumulus, similar to Urnfield burials, and qualifying as the earliest description of cremation rites. This may be an anachronism, as during Mycenaean times burial was generally preferred, and Homer may have been reflecting the more common use of cremation at the time the Iliad was written, centuries later.
Hinduism and Jainism are notable for not only allowing but prescribing cremation. Cremation in India is first attested in the Cemetery H culture (from c. 1900 BCE), considered the formative stage of Vedic civilization. The Rigveda contains a reference to the emerging practice, in RV 10.15.14, where the forefathers "both cremated (agnidagdhá-) and uncremated (ánagnidagdha-)" are invoked.
Cremation remained common but not universal, in both ancient Greece and ancient Rome. According to Cicero, in Rome, inhumation was considered the more archaic rite, while the most honoured citizens were most typically cremated—especially upper classes and members of imperial families.
The rise of Christianity saw an end to cremation, being influenced by its roots in Judaism, the belief in the resurrection of the body, and following the example of Christ's burial. Anthropologists have been able to track the advance of Christianity throughout Europe with the appearance of cemeteries. By the 5th century, with the spread of Christianity, the practice of burning bodies gradually disappeared from Europe.
In early Roman Britain, cremation was usual but diminished by the 4th century. It then reappeared in the 5th and 6th centuries during the migration era, when sacrificed animals were sometimes included with the human bodies on the pyre, and the deceased were dressed in costume and with ornaments for the burning. That custom was also very widespread among the Germanic peoples of the northern continental lands from which the Anglo-Saxon migrants are supposed to have been derived, during the same period. These ashes were usually thereafter deposited in a vessel of clay or bronze in an "urn cemetery". The custom again died out with the Christian conversion of the Anglo-Saxons or Early English during the 7th century, when Christian burial became general.
In parts of Europe, cremation was forbidden by law, and even punishable by death if combined with Heathen rites. Cremation was sometimes used by Catholic authorities as part of punishment for Protestant heretics, which included burning at the stake. For example, the body of John Wycliff was exhumed years after his death and burned to ashes, with the ashes thrown in a river, explicitly as a posthumous punishment for his denial of the Roman Catholic doctrine of transubstantiation.
The first to advocate for the use of cremation was the physician Sir Thomas Browne in 1658. Honoretta Brooks Pratt became the first recorded cremated European individual in modern times when she died on 26 September 1769 and was illegally cremated at the burial ground on Hanover Square in London.
The organized movement to reinstate cremation as a viable method for body disposal began in the 1870s. In 1869 the idea was presented to the Medical International Congress of Florence by Professors Coletti and Castiglioni "in the name of public health and civilization". In 1873, Professor Paolo Gorini of Lodi and Professor Ludovico Brunetti of Padua published reports of practical work they had conducted. A model of Brunetti's cremating apparatus, together with the resulting ashes, was exhibited at the Vienna Exposition in 1873 and attracted great attention, including that of Sir Henry Thompson, 1st Baronet, a surgeon and Physician to the Queen Victoria, who returned home to become the first and chief promoter of cremation in England.
Sir Henry Thompson's main reason for supporting cremation was that "it was becoming a necessary sanitary precaution against the propagation of disease among a population daily growing larger in relation to the area it occupied". In addition, he believed, cremation would prevent premature burial, reduce the expense of funerals, spare mourners the necessity of standing exposed to the weather during interment, and urns would be safe from vandalism. On 13 January 1874, some advocates of cremation, including Anthony Trollope, John Everett Millais, George du Maurier, Thomas Spencer Wells, John Tenniel and Shirley Brooks, held a meeting at Thompson's house in London and formally founded the Cremation Society of Great Britain "...expressly for the purpose of obtaining and disseminating information on the subject and for adopting the best method of performing the process, as soon as this could be determined, provided that the act was not contrary to Law."
The first duty of the Cremation Society was to ascertain whether cremation could be legally performed in the country, and then to construct a first crematorium. In 1878, Sir Henry Thompson bought a piece of land in Woking as a site for the crematorium. Professor Gorini was invited to visit Woking and supervise the erection of his cremation apparatus there. They first tested it on 17 March 1879 by cremating the body of a horse. However, the inhabitants of Woking showed strong antipathy to the crematorium, and appealed to the Home Secretary, Sir Richard Cross, to prohibit the use of the building.
Legalization of cremation came about through the eccentric activities of Welsh Neo-Druidic priest, William Price. After his first child died in 1884 and believing that it was wrong to bury a corpse, thereby polluting the earth, Price decided to cremate his son’s body. He was arrested by the police for the illegal disposal of a corpse. Price successfully argued in court that while the law did not state that cremation was legal, it also did not state that it was illegal. The case set a precedent that, together with the activities of the newly founded Cremation Society of Great Britain, led to the Cremation Act 1902. The Act imposed procedural requirements before a cremation could occur and restricted the practice to authorised places.
In 1885, the first official cremation in the UK took place in Woking. The deceased was Mrs Jeannette C. Pickersgill, a well-known figure in literary and scientific circles. By the end of the year, the Cremation Society of Great Britain had overseen two more cremations, a total of 3 out of 597,357 deaths in the UK that year. In 1886 ten bodies were cremated at Woking Crematorium. During 1888, in which 28 cremations took place, the Cremation Society planned to provide a chapel, waiting rooms and other amenities there. In 1892 a crematorium opened in Manchester, followed by one in Glasgow in 1895, Liverpool in 1896 and Birmingham Crematorium in 1903.
Crematoria in Europe were built in 1878 in the town of Gotha in Germany and later in Heidelberg in 1891. The first modern crematory in the U.S. was built in 1876 by Francis Julius LeMoyne after hearing about its use in Europe. During that time it was thought that people were getting sick by attending funerals of those recently deceased and that decomposing bodies were leaking into the water systems. LeMoyne built the crematory to cremate bodies in a controlled environment primarily for sanitary reasons. Cremation was used to destroy any organic matter that could cause illness and give families a better way to preserve ashes. Before LeMoyne’s crematory closed in 1901, it had performed 42 cremations.
Some of the various Protestant churches came to accept cremation, with the rationale being, "God can resurrect a bowl of ashes just as conveniently as he can resurrect a bowl of dust." The 1908 Catholic Encyclopedia was critical about these efforts, referring to them as a "sinister movement" and associating them with Freemasonry, although it said that "there is nothing directly opposed to any dogma of the Church in the practice of cremation." In 1963, [at Second Vatican Council] Pope Paul VI lifted the ban on cremation, and in 1966 allowed Catholic priests to officiate at cremation ceremonies.
In the U.S. only about one crematory per year was built in the late 19th century. As embalming became more widely accepted and used, crematories lost their sanitary edge. Not to be left behind, crematories had an idea of making cremation beautiful. They started building crematories with stained-glass windows and marble floors with frescoed walls. By 2008, the cremation rate was 36.2% and was growing about 1 percentage point a year, according to CANA. CANA is the largest organization representing crematories and funeral homes in the U.S. and Canada.
Australia also started to establish modern cremation movements and societies. Australians had their first purpose-built modern crematorium and chapel in the West Terrace Cemetery in the South Australian capital of Adelaide in 1901. This small building, resembling the buildings at Woking, remained largely unchanged from its 19th-century style and was in full operation until the late 1950s. The oldest operating crematorium in Australia is at Rookwood Cemetery, in Sydney. It opened in 1925.
In the Netherlands, the foundation of the Association for Optional Cremation in 1874 ushered in a long debate about the merits and demerits of cremation. Laws against cremation were challenged and invalidated in 1915 (two years after the construction of the first crematorium in the Netherlands), though cremation did not become legally recognised until 1955.
During World War II (1939–45) Nazi Germany used specially built furnaces in at least six extermination camps throughout occupied Poland including at Auschwitz-Birkenau, Chełmno, Belzec, Majdanek, Sobibor and Treblinka, where the bodies of those murdered by gassing were disposed of using incineration. The efficiency of industrialised killing of Operation Reinhard during the most deadly phase of the Holocaust produced too many corpses, therefore the crematoria manufactured to SS specifications were put into use in all of them to handle the disposals around the clock, day and night. The Vrba–Wetzler report offers the following description.
At present there are four crematoria in operation at BIRKENAU, two large ones, I and II, and two smaller ones, III and IV. Those of type I and II consist of 3 parts, i.e.,: (A) the furnace room; (B) the large halls; and (C) the gas chamber. A huge chimney rises from the furnace room around which are grouped nine furnaces, each having four openings. Each opening can take three normal corpses at once and after an hour and a half the bodies are completely burned. This corresponds to a daily capacity of about 2,000 bodies... Crematoria III and IV work on nearly the same principle, but their capacity is only half as large. Thus the total capacity of the four cremating and gassing plants at BIRKENAU amounts to about 6,000 daily.
The Holocaust furnaces were supplied by a number of manufacturers, with the best known and most common being Topf and Sons as well as Kori Company of Berlin, whose ovens were elongated to accommodate two bodies, slid inside from the back side. The ashes were taken out from the front side. The furnaces were also unique, in that they were of a "stand alone" type, meaning that there was no visible duct work for the exhaust gases. These furnaces, based around a design commonly used for hospital incinerators, instead vented the gasses down through a series of ducts embedded in the floor, with the help of a draft fan located at the far end of the structure. Once outside, the gasses then rose through a free standing chimney, most notable for the fact that it was not directly attached to the structure of the building itself, nor had a visible duct leading into it.
The cremation occurs in a cremator that is housed within a crematorium and comprises one or more furnaces. A cremator is an industrial furnace that is able to generate temperatures of 870–980 °C (1,600–1,800 °F) to ensure disintegration of the corpse. A crematorium may be part of a chapel or a funeral home or may be an independent facility or a service offered by a cemetery.
Modern cremators automatically monitor their interior to tell when the cremation process is complete. The time required for cremation varies from body to body, and, in modern furnaces, the process may be as fast as one hour per 50 kg (100 lb) of body weight.
A cremator is not designed to cremate more than one human body at a time; cremation of multiple bodies is generally illegal in the United States and many other countries, though exceptions may be made for (for example) still-born twins, or a baby and mother who died during childbirth.
The chamber where the body is placed is called a retort and is lined with heat-resistant refractory bricks. Refractory bricks are designed in several layers. The outermost layer is usually simply an insulation material, e.g., mineral wool. Inside is typically a layer of insulation brick, mostly calcium silicate in nature. Heavy duty cremators are usually designed with two layers of fire bricks inside the insulation layer. The layer of fire bricks in contact with the combustion process protects the outer layer and must be replaced from time to time. The coffin or container is inserted (charged) into the retort as quickly as possible to avoid heat loss through the top door. The container may be mounted on a charger (motorised trolley) that can quickly insert it, or on a fixed or movable hopper that allows the container to slide into the cremator.
In some countries including the United States, there is increasing use of the alkaline hydrolysis process, trademarked as Resomation, which involves the use of lye heated with the body at high pressure, allowing the body to be broken down into its chemical compounds. A cremator is not used. The process is described by its inventors as more ecologically favorable than other forms of cremation.
In the United States federal law does not dictate any container requirements for cremation. Certain states, however, may require an opaque or non-transparent container of all cremations. This can be a simple corrugated-cardboard box or a wooden casket (coffin). Most casket manufacturers provide lines of caskets that are specially built for cremation. Another option is a cardboard box that fits inside a wooden shell, which is designed to look like a traditional casket. After the funeral service, the box is removed from the shell before cremation, permitting the shell to be re-used. Funeral homes may also offer rental caskets, which are traditional caskets used only during the services, after which the bodies are transferred to other containers for cremation. Rental caskets are sometimes designed with removable beds and liners, which are replaced after each use.
In the United Kingdom, the body is not removed from the coffin and is not placed into a container as described above. The body is cremated with the coffin, which is why all British coffins that are to be used for cremation must be combustible. The Code of Cremation Practice forbids the opening of the coffin once it has arrived at the crematorium, and rules stipulate that it must be cremated within 72 hours of the funeral service. Therefore, in the United Kingdom, bodies are cremated in the same coffin that they are placed in at the undertaker's, although the regulations allow the use of an approved "cover" during the funeral service. It is recommended that jewellery be removed before the coffin is sealed, for this reason. When cremation is finished, the remains are passed through a magnetic field to remove any metal, which will be interred elsewhere in the crematorium grounds or, increasingly, recycled. The ashes are then given to relatives or loved ones or scattered in the crematorium grounds where facilities exist.
In Germany, the process is mostly similar to that of the United Kingdom. The body is cremated in the coffin. A piece of fire clay with a number on it is used for identifying the remains of the dead body after burning. The remains are then placed in a container called an ash capsule, which generally is put into a cinerary urn.
In Australia, the deceased is cremated in a coffin supplied by the undertaker. Reusable or cardboard coffins are becoming popular, with several manufacturers now supplying them. For low cost, a plain, particle-board coffin (known in the trade as a "chippie") can be used. Handles (if fitted) are plastic and approved for use in a cremator. Coffins vary from natural cardboard and unfinished particle board (covered with a velvet pall if there is a service) to solid timber; most are veneered particle board.
Cremations can be "delivery only", with no preceding chapel service at the crematorium (although a church service may have been held) or preceded by a service in one of the crematorium chapels. Delivery-only allows crematoria to schedule cremations to make best use of the cremators, perhaps by holding the body overnight in a refrigerator, allowing a lower fee to be charged. Delivery-only is sometimes called west chapel service in industry jargon.
The box containing the body is placed in the retort and incinerated at a temperature of 760 to 1150 °C (1400 to 2100 °F). During the cremation process, the greater portion of the body (especially the organs and other soft tissues) is vaporized and oxidized by the intense heat; gases released are discharged through the exhaust system. The process usually takes 90 minutes to two hours, with larger bodies taking longer time.
Jewelry, such as necklaces, wrist-watches and rings, are ordinarily removed before cremation, and returned to the family. Several implanted devices are required to be removed. Pacemakers and other medical devices can cause surprisingly large, dangerous explosions.
Contrary to popular belief, the cremated remains are not ashes in the usual sense. After the incineration is completed, the dry bone fragments are swept out of the retort and pulverised by a machine called a Cremulator — essentially a high-capacity, high-speed blender — to process them into "ashes" or "cremated remains", although pulverisation may also be performed by hand. This leaves the bone with a fine sand like texture and color, able to be scattered without need for mixing with any foreign matter, though the size of the grain varies depending on the Cremulator used. Their mean weight is 2.4 kg for an adult human, while the mean weight for adult males is about 1 kg higher than that for adult females. There are various types of Cremulators, including rotating devices, grinders, and older models using heavy metal balls. The grinding process typically takes about 20 minutes.
In East Asian countries such as Japan, China, or Taiwan, the bones are not pulverised, unless requested beforehand. When not pulverised, the bones are collected by the family and stored as one might do with ashes.
The appearance of cremated remains after grinding is one of the reasons they are called ashes, although a non-technical term sometimes used is "cremains", a portmanteau of "cremated" and "remains". (The Cremation Association of North America prefers that the word "cremains" not be used for referring to "human cremated remains". The reason given is that "cremains" is thought to have less connection with the deceased, whereas a loved one's "cremated remains" has a more identifiable human connection.)
After final grinding, the ashes are placed in a container, which can be anything from a simple cardboard box to a decorative urn. The default container used by most crematoria, when nothing more expensive has been selected, is usually a hinged, snap-locking plastic box.
An unavoidable consequence of cremation is that a tiny residue of bodily remains is left in the chamber after cremation and mixes with subsequent cremations.
Cremated remains are mostly dry calcium phosphates with some minor minerals, such as salts of sodium and potassium. Sulfur and most carbon are driven off as oxidized gases during the process, although a relatively small amount of carbon may remain as carbonate.
The ash remaining represents very roughly 3.5% of the body's original mass (2.5% in children). Because the weight of dry bone fragments is so closely connected to skeletal mass, their weight varies greatly from person to person. Because many changes in body composition (such as fat and muscle loss or gain) do not affect the weight of cremated remains, the weight of the remains can be more closely predicted from the person's height and sex (which predicts skeletal weight), than it can be predicted from the person's simple weight.
Ashes of adults can be said to weigh from 876 g to 3784 g, with women's ashes generally weighing below 2750 g and men's ashes generally weighing above 1887 g.
Not all that remains is bone. There may be melted metal lumps from missed jewellery; casket furniture; dental fillings; and surgical implants, such as hip replacements. Breast implants do not have to be removed before cremation. Some medical devices such as pacemakers may need to be removed before cremation to avoid the risk of explosion. Large items such as titanium hip replacements (which tarnish but do not melt) or casket hinges are usually removed before processing, as they may damage the processor. (If they are missed at first, they must ultimately be removed before processing is complete, as items such as titanium joint replacements are far too durable to be ground). Implants may be returned to the family, but are more commonly sold as ferrous/non-ferrous scrap metal. After the remains are processed, smaller bits of metal such as tooth fillings, and rings (commonly known as gleanings) are sieved out and may be later interred in common, consecrated ground in a remote area of the cemetery. They may also be sold as precious metal scrap.
Cremated remains are returned to the next of kin in different manners according to custom and country. In the United States, the cremated remains are almost always contained in a thick watertight polyethylene plastic bag contained within a hard snap-top rectangular plastic container, which is labeled with a printed paper label. The basic sealed plastic container bag may be contained within a further cardboard box or velvet sack, or they may be contained within an urn if the family had already purchased one. An official certificate of cremation prepared under the authority of the crematorium accompanies the remains, and if required by law, the permit for disposition of human remains, which must remain with the cremated remains.
Cremated remains can be kept in an urn, stored in a special memorial building (columbarium), buried in the ground at many locations or sprinkled on a special field, mountain, or in the sea. In addition, there are several services in which the cremated remains will be scattered in a variety of ways and locations. Some examples are via a helium balloon, through fireworks, shot from shotgun shells, by boat or scattered from an aeroplane. One service sends a lipstick-tube sized sample of the cremated remains into low earth orbit, where they remain for years (but not permanently) before reentering the atmosphere. Some companies offer a service to turn part of the cremated remains into synthetic diamonds that can then be made into jewelry. Cremated remains may also be incorporated, with urn and cement, into part of an artificial reef, or they can also be mixed into paint and made into a portrait of the deceased. Some individuals use a very small amount of the remains in tattoo ink, for remembrance portraits. Cremated remains can be scattered in national parks in the United States with a special permit. They can also be scattered on private property with the permission of the owner. A portion of the cremated remains may be retained in a specially designed locket known as cremation jewelry, or even blown into special glass keepsakes and glass orbs. The cremated remains may also be entombed. Most cemeteries will grant permission for burial of cremated remains in occupied cemetery plots that have already been purchased or are in use by the families disposing of the cremated remains without any additional charge or oversight.
The final disposition depends on the personal preferences of the deceased as well as their cultural and religious beliefs. Some religions will permit the cremated remains to be sprinkled or retained at home. Some religions, such as Roman Catholicism, prefer to either bury or entomb the remains. Hinduism obliges the closest male relative (son, grandson, etc.) of the deceased to immerse the cremated remains in the holy river Ganges, preferably at the holy city of Triveni Sangam, Allahabad, or Varanasi or Haridwar, India. The Sikhs immerse the remains in Sutlej, usually at Sri Harkiratpur. In southern India, the ashes are immersed in the river Kaveri at Paschima vahini in Srirangapattana at a stretch where the river flows from east to west, depicting the life of a human being from sunrise to sunset. In Japan and Taiwan, the remaining bone fragments are given to the family and are used in a burial ritual before final interment.
Aside from religious reasons (discussed below), some people find they prefer cremation over traditional burial for personal reasons. The thought of a long and slow decomposition process is unappealing to some; many people find that they prefer cremation because it disposes of the body instantly.
Other people view cremation as a way of simplifying their funeral process. These people view a ground burial as an unneeded complication of their funeral process, and thus choose cremation to make their services as simple as possible. Cremation is a more simple disposition method to plan than a burial funeral. This is because with a burial funeral you have to plan for more transportation services for the body as well as embalming and other body preservation methods. With a burial funeral you will also need to purchase a casket, headstone, grave plot, opening and closing of the grave fee, and mortician fees. Cremation funerals only require planning the transportation of the body to a crematorium, cremation of the body, and a cremation urn.
In agriculturally dependent India, it was believed quite early that interring bodies to rot in the soil might render the soil infertile. This is why cremation was preferred initially, even before it was introduced into the Rigveda.
The cost factor tends to make cremation attractive. Generally speaking, cremation is cheaper than a traditional burial service, especially if direct cremation is chosen, in which the body is cremated as soon as legally possible without any sort of services. However, for some even cremation is still relatively expensive, especially as a lot of fuel is required to perform it. Methods to reduce fuel consumption/fuel cost include the use of different fuels (i.e. natural gas or propane, compared to wood) and by using an incinerator (retort) (closed cabin) rather than an open fire.
For surviving kin, cremation is preferred because of simple portability. Survivors relocating to another city or country have the option of transporting the remains of their loved ones with the ultimate goal of being interred or scattered together.
Cremated remains can be scattered or buried. Cremation plots or columbarium niches are usually cheaper than a traditional burial plot or mausoleum crypt, and require less space. Some religions, such as Roman Catholicism, require the burial or entombment of cremated remains, but burial of cremated remains may often be accomplished in the burial plot of another person, such as a family member, without any additional cost. This option is charged for in England in an Anglican church where the fee is set by the Table of Parochial Fees (£36 to incumbent and £78 to church council) a total of £114 in 2010 with a marker charged as extra. It is also very common to scatter the remains in a place the deceased liked—such as the sea, a river, a beach, a park, or mountains, following their last will. This is generally forbidden in public places but easy to do. Some persons choose to have a small part of their ashes (usually less than 1 part in 1000, because of cost constraints) scattered in space (known as space burial and offered by companies such as Elysium Space, Celestis and Ascending Memories). Cremated remains can now also be converted to diamonds.
Cremation might be preferable for environmental reasons. Burial is a known source of certain environmental contaminants, with the coffin itself being the major contaminant; however, in some countries, e.g. the UK, legislation now requires that cremators be fitted with abatement equipment (filters) that remove serious pollutants such as mercury.
Each cremation uses about 110 L (28 US gal) of fuel and releases about 240 kg (540 lb) of carbon dioxide into the atmosphere. Thus, the roughly 1 million bodies that are cremated annually in the United States produce about 240,000 t (270,000 short tons) of carbon dioxide. That’s more CO2 pollution than 22,000 average American homes generate in a year. The environmental impact may be reduced by using cremators for longer periods, and not cremating on the same day as the coffin is received, which reduces the use of fossil fuel and hence carbon emissions. Cremation is therefore becoming more friendly toward the environment though natural burials are also possible. Some funeral and crematorium owners offer a carbon neutral funeral service incorporating efficient-burning coffins made from lightweight recycled composite board.
Another environmental concern is that traditional burial takes up a great deal of space. In a traditional burial, the body is buried in a casket made from a variety of materials. In the United States, the casket is often placed inside a concrete vault or liner before burial in the ground. While individually this may not take much room, combined with other burials, it can over time cause serious space concerns. Many cemeteries, particularly in Japan and Europe as well as those in larger cities, have run out of permanent space. In Tokyo, for example, traditional burial plots are extremely scarce and expensive, and in London, a space crisis led Harriet Harman to propose reopening old graves for "double-decker" burials.
Some cities in Germany do not have plots for sale, only for lease. When the lease expires, the remains are disinterred and a specialist bundles the bones, inscribes the forehead of the skull with the information that was on the headstone, and places the remains in a special crypt.
Christians preferred to bury the dead rather than to cremate the remains, as was common in Roman culture. The Roman catacombs and veneration of relics of saints witness to this preference. For them, the body was not a mere receptacle for a spirit that was the real person, but an integral part of the human person. They looked on the body as sanctified by the sacraments and itself the temple of the Holy Spirit, and thus requiring to be disposed of in a way that honours and reveres it, and they saw many early practices involved with disposal of dead bodies as pagan in origin or an insult to the body.
The idea that cremation might interfere with God's ability to resurrect the body was refuted as early as the 2nd-century Octavius of Minucius Felix, in which he said: "Every body, whether it is dried up into dust, or is dissolved into moisture, or is compressed into ashes, or is attenuated into smoke, is withdrawn from us, but it is reserved for God in the custody of the elements. Nor, as you believe, do we fear any loss from sepulture, but we adopt the ancient and better custom of burying in the earth." And while there was a clear preference for burial, there was no general Church law forbidding cremation until 1866. Even in Medieval Europe, cremation was practiced in situations where there were multitudes of corpses simultaneously present, such as after a battle, after a pestilence or famine, and where there was an imminent fear of diseases spreading from the corpses, since individual burials with digging graves would take too long and body decomposition would begin before all the corpses had been interred.
Beginning in the Middle Ages, and even more so in the 18th century and later, rationalists and classicists began to advocate cremation again as a statement denying the resurrection and/or the afterlife, although the pro-cremation movement more often than not took care to address and refute theological concerns about cremation in their works. Sentiment within the Catholic Church against cremation became hardened in the face of the association of cremation with "professed enemies of God." When some Masonic groups advocated cremation as a means of rejecting Christian belief in the resurrection, the Holy See forbade Catholics to practice cremation in 1886. The 1917 Code of Canon Law incorporated this ban, but in 1963, recognizing that, in general, cremation was being sought for practical purposes and not as a denial of bodily resurrection, the choice of cremation was permitted in many circumstances. The current 1983 Code of Canon Law, states: "The Church earnestly recommends the pious custom of burial be retained; but it does not forbid cremation, unless this is chosen for reasons which are contrary to Christian teaching."
There are no universal rules governing Catholic funeral rites in connection with cremation, but episcopal conferences have laid down rules for various countries. Of these, perhaps the most elaborate are those established, with the necessary confirmation of the Holy See, by the United States Conference of Catholic Bishops and published as Appendix II of the United States edition of the Order of Christian Funerals.
Although the Holy See has in some cases authorized bishops to grant permission for funeral rites to be carried out in the presence of cremated remains, it is preferred that the rites be carried out before cremation, in the presence of the still intact body. Practices that show insufficient respect for the ashes of the dead such as turning them into jewelry or scattering them are forbidden for Catholics.
In 1917, Volume 6 of the American Lutheran Survey stated that "The Lutheran clergy as a rule refuse" and that "Episcopal pastors often take a stand against it." Indeed, in the 1870s, the Anglican Bishop of London stated that the practice of cremation would "undermine the faith of mankind in the doctrine of the resurrection of the body, and so bring about a most disastrous social revolution." In The Lutheran Pastor, George Henry Gerberding stated:
Third. As to cremation. This is not a Biblical or Christian mode of disposing of the dead. The Old and New Testament agree and take for granted that as the body was taken originally from the earth, so it is to return to the earth again. Burial is the natural and Christian mode. There is a beautiful symbolism in it. The whole terminology of eschatology presupposes it. Cremation is purely heathenish. It was the practice among the Greeks and Romans. The mass of the Hindoos thus dispose of their dead. It is dishonoring to the body, intended for a temple of the Holy Ghost and to bear the image of God. It is an insidious denial of the doctrine of the resurrection.
However, Protestant churches welcomed the use of cremation at a much earlier date than the Catholic Church; pro-cremation sentiment was not unanimous among Protestants, however. The first crematoria in the Protestant countries were built in the 1870s, and in 1908, the Dean and Chapter of Westminster Abbey—one of the most famous Anglican churches—required that remains be cremated for burial in the abbey's precincts. Today, "scattering", or "strewing," is an acceptable practice in many Protestant denominations, and some churches have their own "garden of remembrance" on their grounds in which remains can be scattered. Other groups also support cremation. Some denominations, like Lutheran churches in Scandinavia, favour the urns being buried in family graves. A family grave can contain urns of many generations and also the urns of spouses and loved ones.
An early Methodist tract titled Immortality and Resurrection noted that "burial is the result of a belief in the resurrection of the body, while cremation anticipates its annihilation." The Methodist Review noted that "Three thoughts alone would lead us to suppose that the early Christians would have special care for their dead, namely, the essential Jewish origin of the Church; the mode of burial of their founder; and the doctrine of the resurrection of the body, so powerfully urged by the apostles, and so mighty in its influence on the primitive Christians. From these considerations, the Roman custom of cremation would be most repulsive to the Christian mind."
On the other hand, some branches of Christianity oppose cremation, including some minority Protestant groups and Orthodox. Most notably, the Eastern Orthodox and Oriental Orthodox Churches forbid cremation, as a custom, but not dogmatically. Exceptions are made for circumstances where it may not be avoided (when civil authority demands it, or epidemics) or if it may be sought for good cause, but when a cremation is willfully chosen for no good cause by the one who is deceased, he or she is not permitted a funeral in the church and may also be permanently excluded from liturgical prayers for the departed. In Orthodoxy, cremation is perceived by some a rejection of the dogma of the general resurrection.
The Church of Jesus Christ of Latter-day Saints (LDS Church) has, in past decades, discouraged cremation without expressly forbidding it. In the 1950s, for example, Apostle Bruce R. McConkie wrote that "only under the most extraordinary and unusual circumstances" would cremation be consistent with LDS teachings.
However, more recent LDS publications have provided instructions for how to dress the deceased when they have received their temple endowments (and thus wear temple garments) prior to cremation for those wishing to do so, or in countries where the law requires cremation. Except where required by law, the family of the deceased may decide whether the body should be cremated, though the Church "does not normally encourage cremation."
Religions such as Hinduism, Buddhism, Jainism, and Sikhism practice cremation. The founder of Buddhism, Shakyamuni Buddha, was cremated. For Buddhist spiritual masters who are cremated, one of the results of cremation are the formation of Buddhist relics.
A dead adult Hindu is mourned with a cremation, while a dead child is typically buried. The rite of passage is performed in harmony with the Hindu religious view that the microcosm of all living beings is a reflection of a macrocosm of the universe. The soul (Atman, Brahman) is the essence and immortal that is released at the Antyeshti ritual, but both the body and the universe are vehicles and transitory in various schools of Hinduism. They consist of five elements – air, water, fire, earth and space. The last rite of passage returns the body to the five elements and origins. The roots of this belief are found in the Vedas, for example in the hymns of Rigveda in section 10.16, as follows:
Burn him not up, nor quite consume him, Agni: let not his body or his skin be scattered,
O all possessing Fire, when thou hast matured him, then send him on his way unto the Fathers.
When thou hast made him ready, all possessing Fire, then do thou give him over to the Fathers,
When he attains unto the life that waits him, he shall become subject to the will of gods.
The Sun receive thine eye, the Wind thy Prana (life-principle, breathe); go, as thy merit is, to earth or heaven.
Go, if it be thy lot, unto the waters; go, make thine home in plants with all thy members.
The final rites, in case of untimely death of a child, is usually not cremation but a burial. This is rooted in Rig Veda's section 10.18, where the hymns mourn the death of the child, praying to deity Mrityu to "neither harm our girls nor our boys", and pleads the earth to cover, protect the deceased child as a soft wool.
Ashes of the cremated bodies are usually spread in a river, which are considered holy in the hindu practice. Ganga is considered to be the holiest river and Varanasi, which is on the banks of river Ganga the holiest place to be cremated at.
Balinese Hindu dead are generally buried inside the container for a period of time, which may exceed one month or more, so that the cremation ceremony (Ngaben) can occur on an auspicious day in the Balinese-Javanese Calendar system ("Saka"). Additionally, if the departed was a court servant, member of the court or minor noble, the cremation can be postponed up to several years to coincide with the cremation of their Prince. Balinese funerals are very expensive and the body may be interred until the family can afford it or until there is a group funeral planned by the village or family when costs will be less. The purpose of burying the corpse is for the decay process to consume the fluids of the corpse, which allows for an easier, more rapid and more complete cremation.
Judaism traditionally disapproved of cremation in the past (it was the traditional means of disposing the dead in the neighboring Bronze Age cultures). It has also disapproved of preservation of the dead by means of embalming and mummifying, a practice of the ancient Egyptians.
Through history and up to the philosophical movements of the current era Modern Orthodox, Orthodox, Haredi, and Hasidic movements in Judaism have maintained a strict biblical line against cremation, and disapprove of it as Halakha (Jewish law) forbids it. This halakhic concern is grounded in the upholding of bodily resurrection as a core belief of traditional Judaism, as opposed to other ancient trends such as the Sadduccees, who denied it as well as the clear wording of the Torah in Devarim (Deuteronomy) 21:23 "Bury, you will bury him the same day; for the (unburied body) is a curse to God" with both a positive command derived from this verse to command one to bury a dead body and a negative command forbidding neglecting to bury a dead body. Some from the generally liberal Conservative Jewish also oppose cremation, some very strongly.
During the 19th and early 20th centuries, as the Jewish cemeteries in many European towns had become crowded and were running out of space, in a few cases cremation for the first time became an approved means of corpse disposal among the emerging liberal and Reform Jewish movements in line with their across the board rejection of traditional Torah ritual laws having mandatory standing. Current liberal movements like Reform Judaism still support cremation, although burial remains the preferred option.
In Israel, where religious ritual events including free burial and funeral services for all who die in Israel and all citizens including the majority Jewish population including for the secular or non-observant are almost universally facilitated through the Rabinate of Israel which is an Orthodox organization following traditional Jewish law, there were no formal crematories until 2004 when B&L Cremation Systems Inc. became the first crematory manufacturer to sell a retort to Israel. In August 2007, an orthodox youth group in Israel was accused of burning down the country's sole crematorium. The crematorium was rebuilt within weeks by its owner Aley Shalechet and the retort replaced. Since that incident, cremation has taken place in Israel without interruption.
The Baha'i Faith forbids cremation, "He feels that, in view of what ‘Abdu’l-Bahá has said against cremation, the believers should be strongly urged, as an act of faith, to make provisions against their remains being cremated. Bahá’u’lláh has laid down as a law, in the Aqdas, the manner of Bahá’í burial, and it is so beautiful, befitting and dignified, that no believer should deprive himself of it."
Traditionally, Zoroastrianism disavows cremation or burial to preclude pollution of fire or earth. The traditional method of corpse disposal is through ritual exposure in a "Tower of Silence", but both burial and cremation are increasingly popular alternatives. Some contemporary adhererents of the faith have opted for cremation. Parsi-Zoroastrian singer Freddie Mercury of the group Queen was cremated after his death.
Neo-Confucianism under Zhu Xi strongly discourages cremation of one's parents' corpses as unfilial. Han Chinese traditionally practiced burial and viewed cremation as taboo and as a barbarian practice.
Traditionally, only Buddhist monks in China exclusively practiced cremation because ordinary Han Chinese detested cremation, refusing to do it. But now, the atheist Communist party enforces a strict cremation policy on Han Chinese. However, exceptions are made for Hui who do not cremate their dead due to Islamic beliefs.
The minority Jurchen and their Manchu descendants originally practiced cremation as part of their culture. They adopted the practice of burial from the Han, but many Manchus continued to cremate their dead.
Pet cremation is practiced internationally. In Japan, more than 465 companion animal temples are in operation. These venues hold funerals and rituals for lost pets. In Australia, pet owners can purchase services to have their companion animal cremated and placed in a pet cemetery or taken home.
The cost of pet cremation depends on location, where the cremation is done, and time of cremation. The American Humane Society’s cost for cremation of 22.5 kg (50 lb). or less pet is $110 while 23 kg (51 lb). or more is $145. The cremated remains are available for the owner to pick up in seven to ten business days. Urns for the companion animal range from $50 to $150.
In early 2002, 334 corpses that were supposed to have been cremated in the previous few years at the Tri-State Crematory were found intact and decaying on the crematorium's grounds in the U.S. state of Georgia, having been dumped there by the crematorium's proprietor. Many of the corpses were decayed beyond identification. Some families received "ashes" that were made of wood and concrete dust.
Operator Ray Brent Marsh had 787 criminal charges filed against him. On 19 November 2004, Marsh pleaded guilty to all charges. Marsh was sentenced to two 12-year prison sentences, one each from Georgia and Tennessee, to be served concurrently; he was also sentenced to probation for 75 years following his incarceration.
Civil suits were filed against the Marsh family as well as a number of funeral homes who shipped bodies to Tri-State; these suits were ultimately settled. The property of the Marsh family has been sold, but collection of the full $80-million judgment remains doubtful. Families have expressed the desire to return the former Tri-State crematory to a natural, parklike setting.
The magnitude 9.0–9.3 2004 Indian Ocean earthquake triggered a series of lethal tsunamis on 26 December 2004 that killed almost 300,000 people, making them the deadliest tsunamis in recorded history. The tsunamis killed people over an area ranging from the immediate vicinity of the quake in Southeast Asia (Indonesia, Thailand, and the northwestern coast of Malaysia), to thousands of kilometers away in the Indian subcontinent (Bangladesh, India, Sri Lanka, the Maldives), the Horn of Africa (Somalia), and the African Great Lakes (Kenya and Tanzania).
Authorities had difficulties dealing with the large numbers of bodies, and as a result, thousands of bodies were cremated together out of fear that decaying bodies would cause disease. Many of these bodies were not identified or viewed by relatives prior to cremation. A particular point of objection was that the bodies of Westerners were kept separate from those of Asian descent, who were mostly locals. This meant that the bodies of tourists from other Asian nations, such as Japan and South Korea, were mass cremated, rather than being returned to their country of origin for funeral rites.
The cremation rate varies considerably across countries with Japan reporting a 99% cremation rate while Poland reported a rate of 6.7% in 2008. The cremation rate in the United Kingdom has been increasing steadily with the national average rate rising from 34.70% in 1960 to 75.44% in 2015. According to the National Funeral Directors Association the cremation rate in the United States in 2016 was 50.2 percent and this was expected to increase to 63.8 percent by 2025 and 78.8 percent in 2035.

In conclusion, it must be remembered that there is nothing directly opposed to any dogma of the Church in the practice of cremation, and that, if ever the leaders of this sinister movement so far control the governments of the world as to make this custom universal, it would not be a lapse in the faith confided to her were she obliged to conform.
Not only is cremation of the body and internment [sic] of the ashes in an urn a long-standing Buddhist practice, it is also a highly practical idea today, given the scarcity of burial space in crowded modern Japan.

Cremation was unheard of from the time Charlemagne outlawed it (784) until the 17th century. At that point, the practice was urged primarily by those opposed to the church, and for a long time cremation was forbidden by Roman Catholicism and practiced only reluctantly by Protestants. Recently, these strictures have eased, and more and more churches have established columbaria or memorial gardens within their precincts for the reception of the ashes by the faithful.
To the traditionalists, cremation originated among "heathens" and "pagans" and was therefore anti-Christian.
Judaism is a tradition which affirms life. It has struggled from its inception against concentration on death and the deification of the human being as exemplified in the Egyptian concern with mummification and the preservation of the body after death.
The subsequent weight of opinion is against cremation and there is no convincing reason why we should deviate from the sacred established method of burial.
... cremation is un-questionably unacceptable to Conservative Judaism. The process of cremation would substitute an artificial and "instant" destruction for the natural process of decay and would have the disposition of the remains subject to manipulation by the survivors rather than submit to the universal processes of nature.
