Almost 60% of waste disposal sites in Brazil are open dumps with no infrastructure for environmental protection. It is usual to find uncovered waste. The rainwater runs off over the uncovered top of the waste dump. This water may contaminate the soil. This paper discusses the contamination values in the …

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, …

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 …

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 …

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 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 …
