ALKALINE HYDROLYSIS Meaning and
Definition
-
Alkaline hydrolysis, also known as water cremation or resomation, refers to a process of decomposing organic matter in a strong alkaline solution. The method involves the use of a mixture of water and an alkali substance, usually sodium hydroxide or potassium hydroxide, in a high-pressure and high-temperature environment.
In alkaline hydrolysis, the organic matter such as human or animal remains is placed inside a pressure vessel or a sealed chamber. Then, the chamber is filled with the alkaline solution, and the content is heated to a specific temperature, typically around 160°C (320°F). The combination of high temperature and alkalinity accelerates the hydrolysis process, breaking down the organic compounds into their simplest forms, including amino acids, peptides, sugars, and fatty acids.
This method is often used as an alternative to traditional cremation or burial methods, as it offers a more environmentally friendly solution. Alkaline hydrolysis has gained attention due to its potential to reduce carbon emissions and it being a less energy-intensive process compared to cremation.
The resulting liquid, often referred to as "resomation fluid," contains the remains of the organic matter and any water-soluble materials present. It can then be safely discharged or utilized for various purposes, such as being used as a fertilizer or part of the wastewater treatment process.
In summary, alkaline hydrolysis is a process that uses alkaline solution and heat to decompose organic matter, offering an alternative to traditional cremation or burial methods while being environmentally friendly.
Etymology of ALKALINE HYDROLYSIS
The word "alkaline" comes from the Arabic word "al-qaly" meaning "ashes of saltwort" or "alkali". It was introduced to the English language in the 17th century from the Medieval Latin "alkalinus" meaning "pertaining to alkali".
The term "hydrolysis" comes from the Greek words "hydro" meaning "water" and "lysis" meaning "loosening" or "splitting". It was first used in the early 19th century by the Swedish chemist Jöns Jacob Berzelius to describe a chemical reaction where water breaks down a compound into its constituent elements or ions.
Therefore, the term "alkaline hydrolysis" combines the notions of a chemical process involving a base or alkali (alkaline) and the breakdown of a compound through reaction with water (hydrolysis).
