The association is the global forum for waste management with nine technical working groups covering all relevant aspects of sustainable waste management and with special interest in developing country issues. • Working Group on Biological Treatment of Wastes: addresses the biological treatment of the organic fraction of solid waste through
aerobic and
anaerobic decomposition processes. • Working Group on
Collection and
Transfer Technology: addresses the storage, collection, transfer and transportation of solid wastes. • Working Group on Communication: addresses public concerns, comprising public support of and opposition to waste management policies, public consultation and participation, and communication and social issues with focus on human attitudes towards waste. • Working Group on

Including waste minimisation, low waste technology, reuse, recycling, collection, transportation, treatment and disposal of all types of waste, operation of waste management systems, eco-management and audit scheme, environmental protection, work in environment and public participation. • Working Group on
Recycling and
Waste minimisation: addresses both minimisation of solid waste generation and the separation, processing and marketing of materials removed from the municipal solid waste stream. • Working Group on
Thermal Treatment: addresses the thermal treatment of
municipal solid waste, comprising the combustion processes, the production of energy, the control of emissions and the handling of residues. • Working Group on
Landfill: focuses on the design, construction, regulation, and management of landfills, for both industrial and developing nations. Management interests include operations, closure, and post-closure issues, including ground water monitoring and testing,
leachate management, gas management, as well as the quantity and quality of the wastes landfilled. == Development networks and programmes ==
