Abstract

Waste prevention or waste reduction at source is the most preferred solid waste management alternative. This is because waste reduction at source would give the least impact to the environment as opposed to landfill. To embark on waste reduction at source, the concept of material flow in a production system should be understood. Waste prevention plays a key role in reducing waste flow throughout the life cycle of a product. This paper attempts to provide a brief overview on the Municipal Solid Waste (MSW) reduction at source specifically the Life Cycle Assessment (LCA). LCA is one of the preventive and remedial approaches in environmental management and can be broken down into goal definition, inventory analysis, classification and evaluation, and improvement assessment stages. National and international initiatives on LCA were outlined based on the problems on increasing trends on solid waste generation. Preliminary data on relationships between MSW generation and population were outlined. Example on the classification and evaluation on environment impacts by material and waste flow were discussed. The analysis showed that wastes can be categorized into various components and each component can be channeled according to the life cycle of a product. This is important for proper environmental management. This strategy of waste prevention at source is important to enable us to achieve a better quality of life and working towards a more sustainable living.
