Abstract

Yard waste comprises an estimated 6.3% of the total waste generated by residential area in Kuala Lumpur in 2002. It should not be land filled because it is relatively a clean and biodegradable material that can be recycled for soil improvement and other agricultural uses. Paper comprises 6.7% of total residential waste in Kuala Lumpur in 2002. In the past, paper was collected with other Municipal Solid Waste and sent to landfills or incinerators for final disposal. As fewer incinerators have been under construction in recent years, paper disposal has become a serious problem in many cities. Vermicomposting is an alternative for waste management of using earthworms to accelerate the decomposition and stabilization of biodegradable matter into usable end product called vermicompost. The project was focused on the efficiency of Eisenia Foetida in vermicomposting of yard waste and shredded paper generated by Universiti Teknologi Petronas. The study was conducted for 10 weeks by measuring the changes in Total Organic Carbon, Total Kjeldahl Nitrogen, Potassium, Phosphorus and pH in homogenized sample which collected at every 2 weeks of the experimental duration. 20 reactors having five Carbon to Nitrogen ratio (C/N=30, 35, 40, 45 and 50) and four variation initial numbers of earthworms (N0=0, 20, 30 and 40) were tested. The moisture level of substrate was maintained around 70-90% throughout the study period. The maximum reduction of TOC was in R3 at C/N=SO (22.26%). The highest increment of TKN occurred in R3 at C/N=50 (247.53%). The highest increment of K was in R3 at C/N=SO (290.00%). Available P increased greatest in R3 at C/N=SO (728.90 %). The maximum reduction of pH was observed in R2 at C/N=30 (7.400/o). However, the change of pH in vermicomposting was not affected by No. The maximum reduction of weight of substrate after 10 weeks of vermicomposting was in R3 at C/N=45 (44.62%). The experimental data had provided that C/N=SO and No=40 was the most efficient condition for optimum vermicomposting of yard waste and shredded paper.
