ARE DEVELOPING COUNTRIES READY FOR FIRST WORLD WASTE POLICY INSTRUMENTS?

The findings of on-going research conducted within South Africa on waste policy instruments shows that while typical command-and-control instruments lack effective monitoring and enforcement, alternative policy instruments such as economic or information based strategies, are either slow to find favour or fail soon after implementation. Developing countries, such as South …

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 …

DIFFUSED LANDFILL GAS EMISSION MONITORING IN NON-HAZARDOUS WASTE LANDFILLS: STUDY CASES

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 …

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. …

CROP PRODUCTION AND NITROGEN LEACHING RESULTING FROM BIOWASTE AND ONION COMPOST AMENDED SAND

Compost application to agricultural land needs to ensure sustainable development. Hence it is important to determine the fertilizer value and soil conditioning ability of composts, and further to assess the risk of adverse environmental effects, such as excessive nitrate leaching. A lysimeter study was undertaken on poor quality sand to …
