Compost is a mixture of ingredients used as plant fertilizer and to improve soil's physical, chemical, and biological properties. It is commonly prepared by decomposing plant and food waste, recycling organic materials, and manure. The resulting mixture is rich in plant nutrients and beneficial organisms, such as bacteria, protozoa, nematodes, and fungi. Compost improves soil fertility in gardens, landscaping, horticulture, urban agriculture, and organic farming, reducing dependency on commercial chemical fertilizers. The benefits of compost include providing nutrients to crops as fertilizer, acting as a soil conditioner, increasing the humus or humic acid contents of the soil, and introducing beneficial microbes that help to suppress pathogens in the soil and reduce soil-borne diseases.
A funeral is a ceremony connected with the final disposition of a corpse, such as a burial or cremation, with the attendant observances. Funerary customs comprise the complex of beliefs and practices used by a culture to remember and respect the dead, from interment, to various monuments, prayers, and rituals undertaken in their honour. Customs vary between cultures and religious groups. Funerals have both normative and legal components. Common secular motivations for funerals include mourning the deceased, celebrating their life, and offering support and sympathy to the bereaved; additionally, funerals may have religious aspects that are intended to help the soul of the deceased reach the afterlife, resurrection or reincarnation.
Cremation is a method of final disposition of a dead body through burning.
Burial, also known as interment or inhumation, is a method of final disposition whereby a dead body is placed into the ground, sometimes with objects. This is usually accomplished by excavating a pit or trench, placing the deceased and objects in it, and covering it over. A funeral is a ceremony that accompanies the final disposition. Evidence suggests that some archaic and early modern humans buried their dead. Burial is often seen as indicating respect for the dead. It has been used to prevent the odor of decay, to give family members closure and prevent them from witnessing the decomposition of their loved ones, and in many cultures it has been seen as a necessary step for the deceased to enter the afterlife or to give back to the cycle of life.
Embalming is the art and science of preserving human remains by treating them to forestall decomposition. This is usually done to make the deceased suitable for viewing as part of the funeral ceremony or keep them preserved for medical purposes in an anatomical laboratory. The three goals of embalming are sanitization, presentation, and preservation, with restoration being an important additional factor in some instances. Performed successfully, embalming can help preserve the body for many years. Embalming has a very long and cross-cultural history, with many cultures giving the embalming processes religious meaning.
Burial at sea is the disposal of human remains in the ocean, normally from a ship, boat or aircraft. It is regularly performed by navies, and is done by private citizens in many countries.
In archaeology and anthropology, the term excarnation refers to the practice of removing the flesh and organs of the dead before burial. Excarnation may be achieved through natural means, such as leaving a dead body exposed to the elements or for animals to scavenge; or by butchering the corpse by hand. Following excarnation, some societies retrieved the excarnated bones for burial. Excarnation has been practiced throughout the world for hundreds of thousands of years. The earliest archaeological evidence of excarnation is from the Awash River Valley in Ethiopia, 160,000 years ago. Examples of excarnation include "sky burials" in parts of Asia, the Zoroastrian "Tower of Silence", and Native American "tree burials". Excarnation is practiced for a variety of spiritual and practical reasons, including the Tibetian spiritual belief that excarnation is the most generous form of burial and the Comanche practical concern that in the winter the ground is too hard for an underground burial. Excarnation sites are identifiable in the archaeological record by a concentration of smaller bones, which would be the bones that would be the easiest to fall off the body, and that would not be noticed by practitioners of excarnation.
A burial vault is a container, formerly made of wood or brick but more often today made of metal or concrete, that encloses a coffin to help prevent a grave from sinking. Wooden coffins decompose, and often the weight of earth on top of the coffin, or the passage of heavy cemetery maintenance equipment over it, can cause the casket to collapse and the soil above it to settle.
Promession is an idea of how to dispose human remains by way of freeze drying. The concept of promession was developed by Swedish biologist Susanne Wiigh-Mäsak, who derived the name from the Italian word for "promise" (promessa). She founded Promessa Organic AB in 1997 to commercially pursue her idea. The company went bankrupt in 2015 without being able to produce a functioning facility. The idea of promession is questioned and not a functional method according to critics.
The health risks of dead bodies are dangers related to the improper preparation and disposal of cadavers. While normal circumstances allow cadavers to be quickly embalmed, cremated, or buried; natural and man-made disasters can quickly overwhelm and/or interrupt the established protocols for dealing with the dead. Under such circumstances, the decomposition and putrefaction of cadavers goes unchecked, and raises a series of health, logistical, and psychological issues. After disasters with extensive loss of life due to trauma rather than disease—earthquakes, storms, human conflict, etc.—many resources are often expended on burying the dead quickly, and applying disinfectant to bodies for the specific purpose of preventing disease. Specialists say that spraying is a waste of disinfectant and manpower, that "resources that should be going into establishment of water supply, sanitation, shelter, warmth and hygienic food for the survivors are being applied to digging mass graves", and that "Time and time again, eminent and authoritative experts have pointed out that dead bodies do not constitute a health hazard".
Disposal of human corpses, also called final disposition, is the practice and process of dealing with the remains of a deceased human being. Disposal methods may need to account for the fact that soft tissue will decompose relatively rapidly, while the skeleton will remain intact for thousands of years under certain conditions.
In death customs, a viewing is the time that family and friends come to see the deceased before the funeral, once the body has been prepared by a funeral home. It is generally recommended that a body first be embalmed to create the best possible presentation of the deceased. A viewing may take place at the funeral home's chapel, in a family home or at a place of worship, such as a church. Some cultures, such as the Māori of New Zealand, often take the body to the marae or tribal community hall.
Natural burial is the interment of the body of a dead person in the soil in a manner that does not inhibit decomposition but allows the body to be naturally recycled. It is an alternative to typical contemporary Western burial methods and modern funerary customs.
Embalming chemicals are a variety of preservatives, sanitising and disinfectant agents, and additives used in modern embalming to temporarily prevent decomposition and restore a natural appearance for viewing a body after death. A mixture of these chemicals is known as embalming fluid and is used to preserve bodies of deceased persons for both funeral purposes and in medical research in anatomical laboratories. The period for which a body is embalmed is dependent on time, expertise of the embalmer and factors regarding duration of stay and purpose.
Mos Teutonicus was a postmortem funerary custom used in Europe in the Middle Ages as a means of transporting, and solemnly disposing of, the bodies of high-status individuals. Nobles would often undergo Mos Teutonicus since their burial plots were often located far away from their place of death. The process involved the removal of the flesh from the body, so that the bones of the deceased could be transported hygienically from distant lands back home.
Alkaline hydrolysis is a process for the disposal of human and pet remains using lye and heat, and is an alternative to burial or cremation.
The death care industry in the United States includes companies and organizations that provide services related to death: funerals, cremation or burial, and memorials. This includes for example funeral homes, coffins, crematoria, cemeteries, and headstones. The death care industry within the U.S. consists mainly of small businesses, although there has been considerable consolidation over time.
The Funeral Rule, enacted by the Federal Trade Commission on April 30, 1984, and amended effective 1994, was designed to protect consumers by requiring that they receive adequate information concerning the goods and services they may purchase from a funeral provider.
Recompose is a public benefit corporation founded by designer and death care advocate Katrina Spade in 2017, building upon her 2014 non-profit organization Urban Death Project.
