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.
The rate of loss of heat is higher in water and the progression through algor mortis is therefore faster. Cool temperatures slow bacterial growth. Once bloat begins, the body will typically float to the surface and become exposed to flies. Scavengers in the water, which vary with the location, also contribute to decay. [17]
The Zoroastrians in Mumbai and Karachi placed bodies on "Towers of Silence", where birds then could decompose the bodies. [7] Sky burials can provide benefits to the environment, since it does not produce air pollution and the decomposition of the body occurs fairly quickly, when compared to other forms of disposal practices.

Decomposition or rot is the process by which dead organic substances are broken down into simpler organic or inorganic matter such as carbon dioxide, water, simple sugars and mineral salts. The process is a part of the nutrient cycle and is essential for recycling the finite matter that occupies physical space in the biosphere .
As it hydrates, an exothermic reaction results and the solid puffs up. The hydrate can be reconverted to quicklime by removing the water by heating it to redness to reverse the hydration reaction. One litre of water combines with approximately 3.1 kilograms (6.8 lb) of quicklime to give calcium hydroxide plus 3.54 MJ of energy.
Calcination is thermal treatment of a solid chemical compound (e.g. mixed carbonate ores) whereby the compound is raised to high temperature without melting under restricted supply of ambient oxygen (i.e. gaseous O 2 fraction of air), generally for the purpose of removing impurities or volatile substances and/or to incur thermal decomposition.
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 ...
Thermal pollution is the rise or drop in the temperature of a natural body of water caused by human influence. Thermal pollution, unlike chemical pollution, results in a change in the physical properties of water. A common cause of thermal pollution is the use of water as a coolant by power plants and industrial manufacturers. [1]
