GDP & Waste Generation

5Waste Generation

Challenges and Opportunities Cities with increase in economic activities - enormous levelsof waste including hazardous and toxic wastesChanging lifestyles - composition of waste is also changingA growing realization of the negative impacts that wastes onenvironment, land, human health, climate and so onComplexity, costs and coordination of waste management hasnecessitated multi-stakeholder involvement in every stage ofthe waste stream. This calls for an integrated approach towaste management.Local Governments are now looking at waste as a businessopportunity, (a) to extract valuable resources containedwithin it that can still be used and (b) to safely process anddispose wastes with a minimum impact on the environment

Defining ISWMIntegrated solid waste management refers tothe strategic approach to sustainablemanagement of solid wastes covering allsources and all aspects, covering generation,segregation, transfer, sorting, treatment,recovery and disposal in an integrated manner,with an emphasis on maximizing resource useefficiency.

14ISWM Plan An ISWM Plan per se is a package consisting of aManagement 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 wastemanagement; from waste generation through collection,transfer, transportation, sorting, treatment and disposal. Data and information on waste characterization andquantification (including future trends), and assessmentof current solid waste management system foroperational stages provide the basis for developing aconcrete and locality-specific management system.

Beyond UNEPISWM as one of the sub-focal areas under theGlobal Partnership on Waste ManagementPartnership (GPWM) to:develop partnerships with multilateral & bilateraldonors to support implementation of ISWM Plansdevelop partnerships with other organizations workingfor Waste Management – complimenting & multipliereffect for wider coverage of International Cooperation

Lessons Top level political commitment as well asinterest and commitment of localauthorities is crucial to the success ofproject Baseline data is usually not available andrequires considerable time and resources Local project teams are very essential It is very difficult to get cost related date incurrent waste management systems

Lessons contd. Stakeholder consultation provides vitalinformation and greatly improve local ownership ISWM approach being new requires continuouscapacity building in partner institutions Benefits of proper waste management should belooked not just from environmental perspectivebut economic and social benefits should also befactored in Continuous follow-up is required to supportimplementation

Minnesota's Waste Management Act has been in place since 1980 and establishes criteria for the management of three types of solid waste - mixed municipal solid waste (MMSW), construction and demolition wastes (C&D), and industrial solid waste (ISW). The waste management hierarchy establishes preferred management methods based on environmental
