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 …

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 …

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 …

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 …

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 …

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 …
