In many cities in developing countries, the most serious environmental and health problems are related with inadequate solid waste management (SWM). Urbanization or an increase in population, respectively, leads to increased waste generation in urban areas. Most problems are strongly related to inappropriate treatment of the organic fraction of municipal solid waste (OMSW). Composting and anaerobic digestion (AD) are seen as the most favored options to deal with OMSW.

In 1997, the Regional County Municipality (MRC) of La Matapédia, Que., successfully undertook an innovative pilot project in the area of domestic composting with the municipality of San Vicente in El Salvador. With the support of the Federation of Canadian Municipalities’ International Centre for Municipal Development (FCM - ICMD), the MRC decided to renew its involvement, this time in other regions of El Salvador.
To estimate the environmental value for curbside recycling and composting in King County, Sound Resource Management developed a comprehensive recycling and composting environmental costs and benefits valuation model. This model estimates pollution reductions across all three phases of product life cycles that are caused by diverting material discards to recycling or compositing.

While major waste companies promote landfill gas to energy (LFGTE) projects that purport to capture methane released from landfills and convert it to electricity, a better solution lies in organics recycling.
Statement of evidence which illustrates the relationship between particulates / ultrafine particles and human health. The importance of the precautionary principle is also raised.
Currently, much of our biodegradable waste such as food, garden waste, card and paper is sent to landfill, where it breaks down to release methane, a powerful greenhouse gas. Anaerobic digestion (AD) is a treatment that composts this waste in the absence of oxygen, producing a biogas that can be used to generate electricity and heat.
Belo Horizonte has a strong and extensive tradition in municipal planning. Waste management has been a municipal priority and concern since 1900. In the last few decades the City has been at the centre of solid waste management development in Brazil particularly regarding its approach to integration of the informal recycling sector. The Superintendência de Limpeza Urbana (SLU) was created in 1993.
Large studies have shown higher rates of adult and childhood cancer and also birth defects around municipal waste incinerators. Incinerator emissions are a major source of fine particulates, of toxic metals and of more than 200 organic chemicals, including known carcinogens, mutagens, and hormone disrupters.
This paper unpacks the interaction between the informal sector and the private waste contractors and the impact of privatization on the informal sector in Delhi. It uses the unfolding of privatization in Delhi and global experiences to understand the issue and to suggest how waste can be handled in an equitable manner.
