Working Group on Collection and
Transportation Technology
Chair: Theo Lemmen, The Netherlands
The purpose of the Working Group on Collection and
Transportation Technology is to serve as the principal
resource to ISWA in the field of collection and transportation
technology of solid waste. The Working Group
addresses the storage, collection, transfer and transportation
of solid waste.
The Working Groups main objectives are:
• to share information on institutional, technological,
economic and environmental matters concerning
collection and transportation technologies currently
in practice
• to encourage, conduct and share the results of
research and development activities within the
field of waste collection and transportation
Main discussions and activities in 2009/2010 were:
• Collection methods
• Fuel Economy in Waste Collection Trucks
• Waste transportation between cities
• Costs of waste collection services
• Standardisation of containers
• Colours in waste management and recycling
• National Reports on the development within
waste collection
• Publishing of three Working Group reports on
the ISWA Website (one on Waste Collection, one
on Littering and Street Cleaning and one on
Waste Transfer)
• Following the development of the CEN Standards
for vehicles and waste containers
Working Group on Biological Treatment of Waste
Chair: Enzo Favoino, Italy
The Working Group addresses the biological treatment
of the organic fraction of solid waste through aerobic
and anaerobic decomposition processes, including related
instruments (e.g. separate collection, odour management)
and destiny of outputs (quality, application and marketing
of products). It also covers Mechanical-Biological
Treatment (MBT), i.e. the application of biological treatment
to mixed (or residual) waste in order to reduce its
fermentability prior to landfilling, recover further amounts
of materials before final disposal and improve conditions
for energy recovery. The Working Group has also been
mandated to consider issues pertaining to biological treatment
of sludge (composting and anaerobic digestion) and
its application in agriculture.
The Working Group‘s main objectives are:
• to share information on institutional, technological,
economic and environmental matters concerning
biological waste treatment currently in practice
• to encourage, conduct and share the results of
research and development activities within the
field of biological waste treatment
• to define – upon agreement with the GS and STC –
positions to try influence, through provision of
science-based views and information, ongoing
developments in relevant legislation, with reference
e.g. to waste management, soil management, climate
change, and other issues pertaining to management
of organic waste.
Main discussions and activities in 2009/2010 were:
• Follow the development of “end-of-waste criteria”
and when compost is no longer considered as a
waste
• Optimisation of schemes for separate collection
• Food waste disposers
• Management of sludge
• Strategies for optimised management of
biodegradable waste in Developing Countries
• Climate change and biological treatment
• The role of MBT (Mechanical Biological Treatment),
including possible application of MBT outputs
• Markets and marketing strategies for composted
products
