On Solid Wastes and Management “Unless we change the direction we are heading, we might end up where we are going.” –Chinese Proverb Quinay, Pher Errol B. 07M51312 June 09, 2008 Population: 88.6 Million (12 th in the World) Composed of 7,107 Islands with 2,000 currently inhabited Total Area is 30M Ha. 46% is rural area Population density: 268 people per square km Motto: For God, For People, for Nature and for Country
L-R,T-B: Hundred Islands, Banaue Rice Terraces, Manila Bay Sunset, Chocolate Hills, Mayon Volcano, Davao In the early 2000, Metropolitan Manila alone was generating six to eight thousand (6,000 to 8,000) tons of solid wastes. We are simply running out of spaces to throw them into. No local government would like to accept the waste of others and become a host for a dumpsite.
Recycling and Collection 70% collection in urban areas 40% collection in rural areas 13% of Metro Manila wastes are recycled Treatment and Disposal 2% disposed in sanitary landfills 10% composted Rest are in open dump Incineration is prohibited Toxic and Hazardous Wastes About 5% of 2.4M tons are recycled or treated Hospitals in the country generate 6,750 tons/year of hazardous and infectious wastes Ecological Solid Waste Management Act of 2000 was enacted. “Not In My Backyard Syndrome” is still a big problem.
Lack of Dumpsites Stability -Payatas Dumpsite Failure (July 2000) Leachate Collection Groundwater Monitoring Landfill Gas to Energy Project • garbage about 40m high • 60, 000 cubic meters of waste slided • killed 250 people from 700 families • upto 800 people missing Stabililty problem: waste mechanics ?
Methane affects global warming 21 times more than carbon dioxide Dumpsite High in moisture and organic content 60% are organic accounts for 12% of methane released in the Philippines Use of horizontal well Gas extraction Leachate drainage pipes
Many of the residents of Payatas make their living by digging through the influx of "fresh" trash, scavenging for plastic, cardboard, paper, wood, glass, metal and other items that can be sold to recycling agents. The meager earnings made by one person are not enough to buy food even for a day. Whole families are forced to climb the mountain each day, hoping that together they can earn enough to feed everyone. Children as young as four years old must work in their daily struggle for survival.
One example: Quezon City Implement a "total approach" in environmental cleanliness, deployment of environmental police; Support Programs like “Project Basura: Hiwa-hiwalay na”, "Six O’Clock na Bayan" Project, Hydrometallurgical Extraction (Hydromex) Technology, etc.
70-75% are biodegradable and composed of kitchen and yard waste Dry market waste for compost material Buyback center for recyclable materials Open dump to solid waste processing center
Components: Public Awareness Campaign Waste Segregation into biodegradable, recyclable, and residual components Recycling and Composting of recyclable and biodegradable components Landfilling of residual soil waste Farming Activities Thank you very much for listening. “In a time of change, it is learners who inherit the future, the learned find themselves equipped to live only in a world that no longer exists.” -Eric Hofer
