The organic waste was evaluated to be used for the biogas production in compliance with an acute need to reduce the consumption of traditional energy resources. The possibility of using organic waste (corn, straw, branches, fallen leaves, potato peelings) for the biogas production was experimentally confirmed. The influence of the initial fractions size and the temperature on the biogas yield has been studied. The yield of biogas produced from potato peelings was found to be the highest one.

Today there is a need for the development of new technologies of waste utilization, especially biowaste such as fallen leaves because it can accumulate a variety of harmful compounds, including heavy metals. One of the methods of its processing is composting. On the other hand, these leaves can be used to improve soil condition by bioconversion. Actually, a promising way for the realization of this problem is the use of vermiculture technology with the addition of red Californian earthworms.
