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 …

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 …

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 …

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 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 …

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 …
