MODERN INTEGRATED MUNICIPAL SOLID WASTE MANAGEMENT: CONCEPTS AND BENEFITS
The integrated solid waste management (ISWM) system is based on the waste management with an aim to reduce the amount of waste being disposed while maximising resource recovery and efficiency. Based on this waste management hierarchy, an assessment of local needs and conditions should lead to the selection of an appropriate mix of processes and technologies. The preferred waste management strategies within the hierarchy include:
At source reduction and reuse The most preferred option for waste management is to prevent the generation of waste at various stages including the product design, production, packaging, use, and reuse. Waste prevention helps reduce handling, treatment, and disposal costs. It also reduces leachate, air emissions, and greenhouse gases which have significant impacts on the environment.
Waste recycling The next preferred alternative is the recovery of recyclable material resources and strengthening a waste recycling chain through segregation, collection, and reprocessing to create new products.
