Solid Waste Management: Sustainable City Management and Global Climate Control

Challenging the future in relation to solid waste management as a theme leads to two global challenges in the coming years: sustainable city management and global climate control.

In the last 100 years, a considerable level of urbanization has taken place all over the world. Whereas in the year 1950 around 30% of the world population lived in cities, this has now reached 50%. It is expected that by 2030, 60% of the world population will be living in large cities. Maintaining the habitability of the large urban agglomerations is a particular challenge for the future. An important factor for the habitability of large cities is the quality of public utilities and services, including the management of public areas and the removal of municipal and industrial wastes. Experts increasingly acknowledge that a high-quality environment substantially contributes to citizens’ quality of life and feeling of security.

Solid waste management and global climate control connect the field of waste management with the challenge of managing global climate change. Sustainable waste management makes a substantial contribution to the production of sustainable energy and the reduction of greenhouse gas emissions. Examples of this are biogas recovery from landfill sites, waste to energy transformation and the recovery of valuable materials from waste. These issues are relevant for the developed Western world as well as for developing countries and countries in transition.

The ISWA World Congress 2007 ‘Challenging the Future’ will be hosted by the Dutch Waste Association NVRD and will be opened by:

· the President of the NVRD
· the Mayor of the City of Amsterdam
· the Dutch Minister of Housing, Spatial Planning and the Environment
· the President of the ISWA.

The invited keynote speakers are:

· Dr. Achim Steiner, Executive Director of United Nation Environment Programme UNEP.

· Prof. Michael Braungart, Director of McDonough Braungart Design Chemistry (“Cradle to Cradle”).
Waste = Food: Material Flow Management in Biological and Technical Nutrient Systems.

· Prof. Suzanne Rotter, Head of the Waste Management Department Technical University of Berlin.
Environmental and Economic Effects of the EU Emission Trading Scheme on the Waste Sector.

· Mrs Sandra Cointreau, Senior Solid Waste Management Advisor of the World Bank in Washington.
The Changing Face and Growing Complexity of Solid Waste Management in Developing Countries.

· Mrs Cristina Cortinas de Nava, Senior Waste Management Expert in Mexico.
Trade Liberalization and Waste Management in Mexico.

· Mrs Laila Iskandar Kamal, Director of CDI, Community and Institutional Development in Egypt.
Waste Workers of the World: Formal and Informal.

· A representative of the European Commission (to be confirmed).

The maim themes of the congress are:
A. City Management
B. Global Climate Control


CM1 Policy and regulation
Sustainable city management is only possible when the city government has adequate political strategies, legislation and economical instruments in place in order to implement effective management of public spaces and the creation of value from waste. Enforcement is of crucial importance in relation to legislation, whereas the economic viability of sustainable city management requires proper financing.

Some of the papers expected on this topic:
· Sustainable integrated waste management for cities in the developing world.
· Development and application of waste management law domestically and internationally.
· Delivering key waste management infrastructure: Lessons learned from Europe.
· Solid waste management in Ontario in Canada – problems and opportunities.
· Policy options for the control of plastic carry bags.
· Integrated waste management in metropolitan areas.

CM2 Citizens participation and waste prevention
Successful implementation of sustainable city management stands or falls with adequate participation of citizens. In the field of waste prevention and recycling the participation of citizens is an important success factor. Management of public spaces and professional waste collection are also dependent on participation.

Some of the papers expected on this topic:
· Press office; how to cope with media about refuse without being refused.
· Smart ways of action operation models: tools for waste prevention at the workplace.
· Analyses of waste prevention policies applied at the solid waste management in Brazil.

CM3 Management of public spaces
The welfare of city inhabitants can be improved to a great degree when public spaces are kept clean and are properly managed. On a global scale one sees an increasing focus on proper spatial planning to ease the management of public spaces. Another important aspect regarding the spatial planning of public spaces is the siting of waste treatment, recycling and disposal plants. Overcoming public opposition against the siting of waste management facilities represents an important challenge for all the stakeholders involved.

Some of the papers expected on this topic:
· Household waste management in mega cities: the case study of San Paulo in Brasil.
· Evaluation of urbanisation of the city of Samsun in Turkey with a view on sustainable development.
· Waste recycling at public spaces during big events

CM4 Waste collection
Waste collection on a regular and reliable basis is a prerequisite for sustainable city management. The physical layout of cities and the conditions in rural areas demand specific solutions for waste collection. In the industrialized world, separation at source, mechanization and automation in collection is becoming more common. In developing countries, specific solutions are necessary that respond to the physical local situation but are also viable and acceptable in terms of economy, social structure, finances and environment.

Some of the papers expected on this topic:
· Waste sampling results from Galle in Sri Lanka.
· Optimization of trucks with articulated arms for municipal waste collection.
· Municipal solid waste characteristics and management in Samsun in Turkey.
· Waste management practises and sustainable development in Nigeria.


GC1 Policy and regulation
In many countries policies and regulations have been implemented to tackle the challenge of climate management. Internationally, the Kyoto Protocol sets binding national targets for greenhouse gas emissions to the atmosphere and negotiations have now begun on tighter controls over the longer term. The waste processing chain represents a substantial share in the production of greenhouse gas emissions, and therefore is and important opportunity to limit emissions.

Some of the papers expected on this topic:
· Italian greenhouse gas emissions and projections from waste management.
· Waste management technologies for climate change mitigation.
· Waste management in a carbon-constrained world.
· Development of a model for measuring waste minimisation and CO2-emissions from construction waste activities.

GC2 Recycling
Sustainable management of resources starts with the recycling of waste materials and products. Lifecycle analysis of waste recycling shows to what extent recycling activities contribute to materials recycling, energy saving and the reduction of greenhouse gas emissions.

Some of the papers expected on this topic:
· Immobilisation of copper flotation waste in stabilized/solidified products.
· Management of MSWI bottom ash in a life cycle perspective.
· Recycling of Seyitomer-Kutahya thermal power plant coal combustion waste.
· Recycling of plastic waste from farms.
· Decision support tools in solid waste management in Greece.
· Increasing the economics of plastic waste recycling.

GC3 Waste to energy
In industrialized countries waste to energy plants are becoming a more common solution. An important contribution to increasing energy demand is made through waste to energy plants with high energy efficiency. On a European level, a free market in the trade of input materials for waste to energy plants is in the making and it is expected that this will increase the number of waste to energy plants in future.

Some of the papers expected on this topic:
· Energy from waste and biomass by pyrolysis and gasification.
· Utilisation of municipal solid waste in co-generation of electricity and district heating in Vilnius in Lithuania.
· LCA applied to a RDF waste-to-energy plant: comparison between two software programs.
· Evaluation of energy recovery efficiency by household and business waste in incineration plants in Seoul in South Korea.
· Innovative approaches to increase efficiency in waste-to-energy plants

GC4 Bio-mass conversion
In both industrialized and less developed countries, bio-mass conversion of solid waste is becoming more important. In some countries the mechanical and biological treatment (MBT) of mixed waste and the composting of selected organic wastes has grown into a major form of waste treatment and recycling. Separation and processing of the organic components of solid waste can contribute substantially to the production of renewable energy (through digestion), the production of a soil conditioner (through composting) and to reduced landfill space requirements.

Some of the papers expected on this topic:
· Composts produced from organic waste and their use in remediation contaminated sites.
· Septic tank sludge treatment alternative: co-disposal with municipal waste.
· Utilizing solid waste from a brewery as a substrate in enzyme production.
· Overview of potential novel treatment technologies for food waste.
· Achieving acceptable heavy metal levels in municipal solid waste compost.
· Nitrogen availability and leaching from bio-waste and union amended soil.

GC5 Landfilling
On a global basis, landfilling of waste will still be the most widely-used method of waste management in the coming decades. Sustainable landfilling, where this activity minimizes the environmental impacts and greenhouse gas emissions, looks set to be introduced as the global standard.

Some of the papers expected on this topic:
· From world summit directives to local compliance; the local chance of landfill reduction in emerging economies.
· Enhanced waste stabilisation in bioreactor landfill simulators.
· Quality of manual sorting with respect to biomass content of the residue.
· New strategies for sustainable and cost-saving aftercare of closed landfills.
· Closure and post-closure of landfills in Malaysia.

Publishing of accepted congress papers

All accepted papers will permanently and for indefinite time be published at the official ISWA website: The Programme Committee of the ISWA World Congress 2007 will forward a selection of the most qualified papers to the Editorial Board of the professional journal Waste Management & Research. After peer reviewing, these papers will be published in a special congress issue of Waste Management & Research.
