Solid waste is one of the biggest effects of humans to nature. Unlike other biological species, humans produce too much solid waste for nature to keep up. Colegio de San Juan de Letran Calamba, produces 65 tons of solid waste per year. Non-biodegradable wastes, which share the biggest portion in the collected solid wastes, caused difficulties in terms of sorting and storing because of poor management and treatment. When non- biodegradable wastes filled up the storage, it caused pollution. Not having the ability to be decomposed by microorganisms, non-biodegradable wastes require different kinds of process to be destroyed. Burn it, and it will destroy the atmosphere. Dump it in the ocean, and it will contaminate the water. Bury it and it will pollute the soil. Faced with these problems, the proponents designed a non-biodegradable waste management system in Colegio de San Juan de Letran. The proposed system included three alternative solutions: (1) design and installation of plastic metal separator with garbage shredder; (2) design and installation of garbage granulator; and (3) design and installation of garbage compactor. These alternative solutions were designed to minimize the volume of produced non-biodegradable waste for more convenient storing and management.
