MUNICIPAL SOLID WASTE COMPOSITION, CHARACTERIZATION AND RECYCLABLES POTENTIAL: A CASE STUDY EVALUATION IN MALAYSIA

摘要

Efficient and sound waste management in developing country like Malaysia requires reliable data on solid waste generation and composition. At present there is no data available on municipal solid waste (MSW) generation and composition retained at major districts in Kelantan. It hascaused severe difficulty in decision making for comparability and applicability of the waste management options. Here, we reported a baseline data for MSW composition, characterization and recyclable potentials from three major dumping sites which are Beris Lalang, Bukit Akil and Renok inKelantan, Malaysia. Manual sorting was used for classifying the collected wastes into the following categories: food/organics, paper, tetrapak, plastic film, plastic rigid, napkins, textiles, rubber, leather, garden, glass, metals, household hazardous waste and others. The daily average MSWfor the present period was calculated at 0.90, 0.60 and 0.89 kg/cap/day respectively for three districts studied. A direct sampling of MSW as disposed at three dumping sites was conducted based on MS2505:2012 standard method to come out with appropriate MSW composition. The results of theanalyzed component showed that organic fraction was dominant (28-44%), followed by paper (12.5-22%), tetrapak (11.5-12.5%), plastics film (3.4-8.49%) and plastic rigid (6.22-14.84%). The results suggested that there is great possibility for recyclable wastes diversion practice which shouldbe able to recover more than 35% of total MSW generation. The figure implies that, more than 376 tonne/day of MSW generation could be diverted and has the potential for recycling, reprocessing and reduced.
