The aim of this work is to develop the automated system of organic waste processing. The existing devices have been analyzed and their disadvantages have been revealed with the aim to create more perfect system. The construction of robot system of organic waste processing has been developed. A mathematical model of physical processes inside a bioreactor has been developed. Optimal parameters for effective, fast and high-quality conduct of the process have been revealed during the modeling. The experimental plant has been created for carrying out the study. All that allows to create modern, functional and autonomous system, which will meet all requirements of environmental security.
