Common wild pig (boar) corpse decomposition timelapse. Decomposition is the process in which the organs and complex molecules of animal and human bodies break down into simple organic matter over time. In vertebrates, five stages of decomposition are typically recognized: fresh, bloat, active decay, advanced decay, and dry/skeletonized. [1]
The human body is composed of approximately: 64% water, 20% protein, 10% fat, 1% carbohydrate, 5% minerals. [1] The decomposition of soft tissue is characterized by the breakdown of these macromolecules, and thus a large proportion of the decomposition products should reflect the amount of protein and fat content initially present in the body.

In water ecosystems, relatively little waste collects on the water bed, and so the progress of decomposition in water takes a more important role. Investigating the level of inorganic salts in sea ecosystems shows that unless there is an especially large supply, the quantity increases from winter to spring—but is normally extremely low in summer.
Generally, the term decomposition encompasses the biochemical processes that occur from the physical death of the person (or animal) until the skeletonization of the body. Putrefaction is one of seven stages of decomposition ; as such, the term putrescible identifies all organic matter (animal and human) that is biochemically subject to ...
Decomposition rates are low under very wet or very dry conditions. Decomposition rates are highest in damp, moist conditions with adequate levels of oxygen. Wet soils tend to become deficient in oxygen (this is especially true in wetlands), which slows microbial growth. In dry soils, decomposition slows as well, but bacteria continue to grow ...
Furthering this research at the Tennessee Body Farm, Bass and his team began to expand into other forensic investigative questions such as what was the climate during death, if water was involved during the decomposition process, and if clothing was on the body or not during decomposition. [47]
Decomposition microbiology can be divided into two fields of interest, namely the decomposition of plant materials and the decomposition of cadavers and carcasses. The decomposition of plant materials is commonly studied in order to understand the cycling of carbon within a given environment and to understand the subsequent impacts on soil ...
An alkaline hydrolysis disposal system at the Biosecurity Research Institute inside of Pat Roberts Hall at Kansas State University. Alkaline hydrolysis (also called biocremation, resomation, [1] [2] flameless cremation, [3] aquamation [4] or water cremation [5]) is a process for the disposal of human and pet remains using lye and heat; it is alternative to burial, cremation, or sky burial.
