Experimental study and numerical reproduction of self-weight consolidation behavior of thickened tailings
Abstract: Thickened tailings, defined as mineral wastes that behave as a non-Newtonian fluid, show a small yield stress and release a small amount of water following deposition. Thickening has become an increasingly used ...
Methodology to determine the extent of anaerobic digestion, composting and CH4 oxidation in a landfill environment
Abstract: An examination of the processes contributing to the production of landfill greenhouse gas (GHG) emissions is required, as the actual level to which waste degrades anaerobically and aerobically beneath covers has ...
Influence of capillary barrier effect on biogas distribution at the base of passive methane oxidation biosystems: Parametric study
Abstract: The efficiency of methane oxidation in passive methane oxidation biosystems (PMOBs) is influenced by, among other things, the intensity and distribution of the CH4 loading at the base of the methane oxidation ...
Landfill gas distribution at the base of passive methane oxidation biosystems: Transient state analysis of several configurations
Abstract: The design process of passive methane oxidation biosystems needs to include design criteria that account for the effect of unsaturated hydraulic behavior on landfill gas migration, in particular, restrictions to ...
Effects of preconditioning the rhizosphere of different plant species on biotic methane oxidation kinetics
Abstract: The rhizosphere is known as the most active biogeochemical layer of the soil. Therefore, it could be a beneficial environment for biotic methane oxidation. The aim of this study was to document - by means of batch ...
Optimization of a landfill gas collection shutdown based on an adapted first-order decay model
Abstract: LandGEM’s equation was reformulated to include two types of refuse, fast decaying refuse (FDR) and slow decaying refuse (SDR), whose fractions and key modeling parameters k and L0 were optimized independently for ...
Behaviour of tire shred – sand mixtures
Abstract: Tire shreds and tire shred-soil mixtures can be used as alternative backfill material in many geotechnical applications. The reuse of tire shreds may not only address growing environmental and economic concerns, ...
Comparação entre metodologias USEPA e IPCC para estimativa teórica de produção de biogás em aterro municipal
Other titre : Comparison between USEPA and IPCC methodologies for theoretical estimation of biogas production in landfill
Resumo: O aproveitamento energético do biogás de aterros sanitários é uma alternativa sustentável para a disposição final de gases residuais. A estimativa teórica da produção desse biogás torna-se uma ferramenta muito útil ...
Biogas generation potential of anaerobic co-digestion of municipal solid wastes and livestock manures
Abstract: This study evaluated the potential of biogas generation of the fresh organic fraction of municipal solid wastes (OFMSW) inoculated with swine manure and cattle manure, based on the volatile solids content obtained ...
Energy generation from municipal solid waste and the current scenario of biogas recovery in Brazil
Other titre : Geração de energia a partir de resíduos sólidos urbanos e o panorama atual da recuperação de biogás no Brasil
Abstract: The landfill is a method of treatment and final disposal of municipal solid waste (MSW) widely employed all over the world, mainly in developing countries. The biogas released from landfills raises environmental ...
