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. …

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 first set of factors includes the economic situation of the community: income, unemployment, and the housing density. The second set …

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 …

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 …

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 …

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 …

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 …

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 paper is concerned with the anaerobic co-digestion of wastewater treatment plant sludge and organic waste coming from the fresh food department of a large market store where a source separated collection system is installed. In particular the study is aimed to verify – by means of pilot plant operation …
