waste recycling

The article is devoted to the development of low - waste environmentally safe technology for the production of combined metal oxide anodes. Low waste is realized due to recycling of nitrogen oxides and heavy metal compounds. It is established that the depth of purification of air from nitrogen oxides with water with neutralization of nitric acid with manganese carbonate exceeds 95%. It was determined that the residual concentrations of heavy metals of lead and copper in treated wastewater do not exceed, respectively, 0.002 and 0.06 mg/m3.

In the conditions of constant deterioration of the environment, municipal solid waste management (MSW) in Ukraine remains one of the most pressing challenges in environmental safety because of its significant accumulation in landfills and the lack of effective mechanisms for its disposal. Approximately 40- 50% of municipal solid waste is organic, so the removal of this part of waste from landfills through composting and conversion of waste into secondary material resources will significantly reduce the environmental load on existing and potentially planned landfills.
