METHANE GENERATION POTENTIAL AND BIODEGRADABILITY OF MSW COMPONENTS

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. …

THE EFFECTS OF LOCAL CULTURAL AND SOCIO-ECONOMIC FEATURES ON THE STRUCTURE OF SOLID WASTE MANAGEMENT IN DEVELOPING COUNTRIES: THE CASE OF THE PHILIPPINES AND VIETNAM

This paper investigates the effects of local socio-economic factors on the adoption of various waste management technologies in the Philippines and Vietnam. Three sets of factors have been selected. The first set of factors includes the economic situation of the community: income, unemployment, and the housing density. The second set …

A STUDY ON THE BEHAVIOUR OF ALTERNATIVE DRAINAGE SYSTEMS IN LANDFILLS

Drainage and liquid collection systems are components of fundamental importance in landfills and waste disposal areas. Sand, gravels and geosynthetics are materials commonly used as filters and draining media in landfill drainage systems. However, the waste itself contains elements that could be employed as drainage material. This paper presents an …

MODERN LANDFILL TECHNOLOGY – LANDFILL BEHAVIOR OF MECHANICAL MECHANICALBIOLOGICAL PRE-TREATED WASTE

The mechanical-biological pre-treatment of wastes has far-reaching effects on the construction and operation of landfills. The emplacement and storage behaviour of the mechanical-biological pre-treated waste (MBW) in the landfill will fundamentally different itself in many areas from the experiences which have been gained in the past with the operation of …

COMPARISON OF THE ENERGY RECOVERY AND USAGE OF COMPOST FROM GREEN WASTE: WHAT IS THE IMPACT ON PRIMARY RESOURCES?

The German Biomass Regulation (§2 and §3) allows the use of bio and green waste for energy recovery, including electricity generation. This implies governmental support for energy recovery of this waste. The sponsored amount – calculated through the calorific value – ranges between 85 and 160 €/t. The aim of …
