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 …

A Study on hierarchical framing and standardization of leaching tests for recycled products are in progress under a research project “Studies on methodology to set environmental safety quality level based on standardization of the testing system for secondary recycled products”. The aim is focused on the risks for soil and …

Despite the fact that Mexico has taken greater steps into improving its waste management, many of its smaller communities still face severe challenges associated with the collection and disposal of waste. In the state of Morelos, the number of problems related to waste is increasing as the population’s density and …

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 …

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 …

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. …

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 …

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 …

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 …
