Indoor air quality assessment on polygons for solid municipal waste for microbial contamination and a method of its cleaning

Abstract

Landfill biogas contains large amounts of toxic and harmful impurities and may be a source of microbiological contamination of both the complex municipal waste landfill itself and adjacent territories. This paper uses modern biotechnologies designed to protect the environment, to study the quantitative and qualitative composition of biogas for harmful factors, as well as for harmful substance removal from biogas. An assessment was made of air purification in the premises near landfills and adjacent territories using green plantations and a biological system based on an apparatus-biological complex for purification from microbiological contamination. The data obtained in our laboratory studies show that such apparatus-biological complexes can reduce the negative influence on the personnel and workers at operative points and the inhabitants of adjacent territories by air purification.
