Abstract
The article examines the problem of processing poultry waste using extrusion technology. Bird droppings contain elements necessary for plant nutrition. This chemical composition makes it a valuable organic raw material for use as organic fertilizer. However, manure requires processing before being introduced into the soil. The main goal of the study is to reduce the moisture content of the mixture of high-moisture poultry waste to a level sufficient for high-quality extrusion into fertilizer. Reducing the moisture content of the mixture is possible by mixing them with vegetable fillers. Litter components or plant waste were selected as fillers. As a result of measuring the moisture content of the components of the mixture, it was determined: poultry manure with litter (PP) turned out to be the least wet and can be used for processing by extrusion; bird droppings from young stock (PM) and bird droppings from adult birds (PV) can be used for extrusion processing when mixed with vegetable fillers in a ratio of 1: 1 and 1: 2, respectively.
