There are very few construction and demolition (C&D) waste recycling centres in Brazil. Data relating to C&D waste management and recycling in Brazil were collected and analysed to encourage the building and operation of new units. Based on the results of this analysis, a conceptual model was proposed to perform …

The objective of the present work is to present a physical characterization of the polymeric wastes conducted in the conventional collection of the municipality of São Carlos, SP. The method adopted for physical characterization was by sampling, where the number of samples involved all of the sections, with the weight …

With the aim of reducing Greenhouse gases emissions and in general environmental impact of landfills, scientific research has been concentrated, since several years, on monitoring and control of non-collected emissions of landfill gas, since these are the main responsible for the landfill environmental load. With reference to these issues, the …

The paper is concerned with the anaerobic co-digestion of wastewater treatment plant sludge and organic waste coming from the fresh food department of a large market store where a source separated collection system is installed. In particular the study is aimed to verify – by means of pilot plant operation …

As an important parameter for estimation of methane generation from landfills, we measured ultimate methane yields (M0 VS) of various municipal solid waste (MSW) components, which were obtained by classifying bulk waste carried into S landfill in Korea. Food wastes exhibited the highest M0 VS of 420mL CH4/g VS. Misc. …

Almost 60% of waste disposal sites in Brazil are open dumps with no infrastructure for environmental protection. It is usual to find uncovered waste. The rainwater runs off over the uncovered top of the waste dump. This water may contaminate the soil. This paper discusses the contamination values in the …

The present study is concerned with the economic and environmental evaluation of landfill gas exploitation system in reference to an existing study case landfill, located in Tuscany Region (Italy). Landfill gas production, during the different life phases of the study case landfill, has been predicted according to a mathematical model, …
