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 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 …
Mais »LANDFILL GAS ENERGY RECOVERY ECONOMIC AND ENVIRONMENTAL EVALUATION FOR A STUDY CASE
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, …
Mais »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 …

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 …
Mais »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 …

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 …

This paper presents the outline of a demonstration project that aims to develop a safe and sustainable system for the management of Municipal Solid Waste (MSW) in Bangladesh through the practical application of WasteSafe Approach. Khulna, the third largest city of Bangladesh and situated at the Southwest region of the …
Mais »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. …
