Chemical analysis of compost produced from organic plant waste in a biothermal installation

Abstract

Currently, the problem of processing various types of organic waste from agricultural and food production is becoming more pressing, since they most often have to be disposed of by paying for this service. At the same time, the cost of protein components and, as a consequence, feed is constantly increasing.
The development of new technologies and technical solutions is becoming relevant.
One of these technologies, which makes it possible to produce feed products for fattening animals, is the biothermal processing of organic waste using special installations.
Technological solutions used in ECO biocomposters made it possible to create a completely autonomous machine for processing food and organic waste of various volumes.
In our article we publish the results of a chemical analysis of the resulting compost after processing plant waste - vegetables and root crops - for compliance with certain indicators of GOST 9268-2015 (concentrated feed for cattle).
The studies carried out established compliance with GOST for a number of indicators: the mass fraction of crude fat, crude protein, soluble carbohydrates, phosphorus and nitrogen was normal. An increased content of moisture and crude fiber was observed, which is associated with the composition of the starting material and the features of the technology.
