Hydrothermal treatment of organic waste

Abstract

The yield and properties of solid and liquid products of hydrothermal treatment of organic waste were determined with cheese, meat, and apples as an example. The solid products of hydrothermal treatment of cheese and apples have higher carbon content, lower oxygen content, and, correspondingly, higher heat of combustion compared to the initial biomass, which allows these products to be considered as a promising solid biofuel. The oils obtained in experiments with cheese and meat also have higher carbon content and higher heat of combustion compared to the initial substances, which allows these products to be considered as a promising liquid biofuel.
