Alkaline hydrolysis, also known as water cremation or aquamation, is a process that involves the breakdown of organic material using a combination of water, heat, and alkaline substances such as potassium hydroxide or sodium hydroxide. This method effectively facilitates the decomposition of biological tissues.

The process results in the formation of hydrolysate, a liquid that contains the dissolved organic matter and inorganic minerals, as well as calcium phosphate, which is a component of the 'ashes.' The alkaline solutions alter the chemical bonds in the organic matter, leading to its decomposition into simpler compounds. The remaining solids after alkaline hydrolysis primarily consist of the mineral components of the bones, which will appear as a white powder, commonly referred to as 'ashes.'

Understanding this process highlights the differences between alkaline hydrolysis and traditional cremation, where combustion leads to gas emissions and a different residue outcome. In contrast, alkaline hydrolysis primarily yields a liquid hydrolysate and a small volume of ash-like material, contrasting with other methods that may leave behind only liquid or solidified organic matter without the mineral ash component.
