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 …

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 …

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 …

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 …

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 …

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 …

The objective of the present work is to present a physical characterization of the polymeric wastes conducted in the conventional collection of the municipality of São Carlos, SP. The method adopted for physical characterization was by sampling, where the number of samples involved all of the sections, with the weight …

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 …

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 …
