Abstract


The Ecological Solid Waste Management Act or RA 9003 provides the legal framework for an efficient solid waste management including waste segregation, recycling, establishment of Materials Recovery Facility (MRF), and composting. RA 9003 also emphasizes the need to create institutional mechanisms and incentives to come up with environmentally sound waste management facilities. This study aimed to determine the amount and type of wastes generated in a government research institution and to develop a small-scale drum composter for handling of biodegradable waste. Waste analysis and characterization study (WACS) was conducted for four days in the Industrial Technology Development Institute (ITDI) of DOST. Daily collected wastes were sorted and weighed based on types, i.e. biodegradable, recyclable, residual, inert, and special waste. Results showed that ITDI generates an average of 57.4 kilograms solid wastes per day (kg d-1). Biodegradable waste constitutes 59% of these wastes or about 34 kg d-1. The remaining wastes composed of 19% recyclable, 17% residual, 4% special wastes, and less than 1% inert. Around 56% of ITDI waste came from R&D Divisions, 33% from Technical Services Divisions, and 11% from Support Services Divisions and other offices. A small-scale motorized composter was fabricated consisting of two plastic drums. Each drum can accommodate 50 kg solid waste just enough for the organic waste generated in the Institute. WACS data and the composting unit will be very useful to improve the Institute’s solid waste management plan and in establishing MRF. The simple composter can be adapted by barangays, schools, universities, small farms, other government institutions, and interested groups looking for small-scale composting technology.
