Study of a composting process in the green waste processing plant

Abstract

Composting of sewage sludge together with green waste such as grass, leaves, branches, etc. is carried out in Poland in a number of facilities. A common problem of all compost plant operators is the selection of the type of composting technology and its modification to the conditions prevailing in a particular region. This is because the waste, the facilities are exposed to, differs and the technology must be adapted to the conditions prevailing in the given facility. In the field of technological research of the composting process, the research aims to characterize the conditions for composting organic waste in relation to the efficiency achieved, indication of the optimal technological parameters and assistance in the selection of the target composting technology. Waste composting technology is based on the appropriate selection of the composition of prisms and the periodic transfer of the prisms by means of a special turning machine. For the purpose of this research, hypotheses were formulated on the intensity of the composting process depending on the technological parameters of the prism (the size of the prism. the types of waste), the properties of the waste, and the intensity of aeration by turning. The results may be useful for compost plant operators and waste processing companies.
