Experimental Tests on the Influence of Waste Covering Layer on Odour Reduction

Waste management is one of the most relevant problems of environmental protection. Landfills constitute an unavoidable component of the waste management system. The article discusses the problem of landfill odours. Reduction of waste tipping areas and temporary waste covering are the most efficient measures for reducing odours from landfills. The article presents the results of experimental tests on the use of building debris for the reduction of odours from landfills. Tests were performed by applying dynamic olfactometry. Upon covering waste with the building debris layer of 10 cm thickness odour thresholds fell from 51.0 to 79.7% compared with uncovered waste.
