Zoocompost – a solution to the organic waste problem and a material for soils polluted with heavy metals remediation

Recycling of organic waste is an acute environmental problem. Recently, the most promising are innovative technologies for bio-processing of organic residues with the help of insects. The method of obtaining organic fertilizer from organic waste using larvae of the Black Lion fly is quite new in the agro-industrial sphere and allows solving the problems of protein production and processing of organic waste. An important task is also to study the possibility of using a zoo compost for the restoration of technogenically disturbed soils. It was found that the zoo compost retains its stability and physico-chemical characteristics for a long time, adding it in an amount of 1.25 wt.% to soil samples reduces the content of the mobile form of cadmium by 41%. Thus, it is possible to recommend the use of zoocompost as a biofertilizer, as well as for remediation of soils contaminated with heavy metals.
