Waste Generation

Challenges and Opportunities • • • •



Cities with increase in economic activities - enormous levels of waste including hazardous and toxic wastes Changing lifestyles - composition of waste is also changing A growing realization of the negative impacts that wastes on environment, land, human health, climate and so on Complexity, costs and coordination of waste management has necessitated multi-stakeholder involvement in every stage of the waste stream. This calls for an integrated approach to waste management. Local Governments are now looking at waste as a business opportunity, (a) to extract valuable resources contained within it that can still be used and (b) to safely process and dispose wastes with a minimum impact on the environment

Defining ISWM Integrated solid waste management refers to the strategic approach to sustainable management of solid wastes covering all sources and all aspects, covering generation, segregation, transfer, sorting, treatment, recovery and disposal in an integrated manner, with an emphasis on maximizing resource use efficiency.

ISWM Plan • An ISWM Plan per se is a package consisting of a Management System including: Policies (regulatory, fiscal, etc.), Technologies (basic equipment and operational aspects) Voluntary measures (awareness raising, self regulations) • A Management System covers all aspects of waste management; from waste generation through collection, transfer, transportation, sorting, treatment and disposal. • Data and information on waste characterization and quantification (including future trends), and assessment of current solid waste management system for operational stages provide the basis for developing a concrete and locality-specific management system.

UNEP Strategy for ISWM 1. Within UNEP ISWM activities to support Bali Strategic Plan on Capacity Building and Technology Support & to assist in UNEP Waste Strategy & Action Plan

2. Beyond UNEP ISWM as one of the sub-focal areas under the Global Partnership on Waste Management Partnership (GPWM) to: develop partnerships with multilateral & bilateral donors to support implementation of ISWM Plans develop partnerships with other organizations working for Waste Management – complimenting & multiplier effect for wider coverage of International Cooperation

Lessons •

Top level political commitment as well as interest and commitment of local authorities is crucial to the success of project



Baseline data is usually not available and requires considerable time and resources



Local project teams are very essential



It is very difficult to get cost related date in current waste management systems

Lessons … contd. •

Stakeholder consultation provides vital information and greatly improve local ownership



ISWM approach being new requires continuous capacity building in partner institutions



Benefits of proper waste management should be looked not just from environmental perspective but economic and social benefits should also be factored in



Continuous follow-up is required to support implementation
