Recycling of Household Organic Waste in Malaysia: the Challenges
Recycling is a feasible option to divert household organic component from landfill disposal. Thus, the objective of this study was to determine the highest Practicality Value (PV) between composting, vermicomposting and refuse-derived fuel (RDF) conversion as recycling options for Malaysian household organic waste. PV was calculated based on the ease of operating techniques, equipments required, costs incurred and public acceptance. Composting set-ups by individual household is less practical due to the low volume of organic waste, at approximately 1.0kg/day per family that the optimum composting temperature cannot be reached within a reasonable duration of 3-4 weeks. It can be carried out successfully if it is conducted at a centralized plant. Vermicomposting on the other hand was found to be the best option with the utilization of Eisenia feotida. It catered low volume factor of composting mass. Lastly, RDF conversion of MSW was found to generate material with an average calorific value of 17KJ/g of MSW. Production of materials with low calorific value was due to the high moisture content of Malaysian MSW (70-80%). By taking into consideration the above factors, vermicomposting has the highest PV (2.62) and offers the most practical recycling solution for household organic wastes in Malaysia.
