On Solid Wastes and Management

Quinay, Pher Errol B. 07M51312 June 09, 2008

“Unless we change the direction we are heading, we might end up where we are going.” –Chinese Proverb

 Population: 88.6 Million (12th 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

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

  • ut 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

  • ne 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

slide-9
SLIDE 9

 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 “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

Thank you very much for listening.
