State of Solid Waste

Management

Metro Cebu Statistics (as of 2001) Population = 756,243 Waste collection efficiency = 80% Estimated waste discharge per day = 0.7 kg

per person Total solid waste per day = 756,243 × 0.7 kg =

529,370 kg (57% is residential waste)

Problems Regarding Solid Waste

Management

Major Problems Weak institutional and organizational systems

for solid waste management Problems in the upper waste stream Problems in the lower waste stream

Problems Affecting the Upper Waste Stream Inefficiency in garbage collection due to lack

of garbage vehicles No waste segregation done at the source of the

waste No waste recycling done at the point of

generation

What happens after the collection? Garbage is brought to the dumpsites.

(e.g. Sanitary Landfill in Inayawan)

Problems Affecting the Lower Waste Stream Insufficiency of the Sanitary Landfill

operation Materials Recovery and Storage Building problem Incinerator problem Lack of soil covering Improper leachate treatment No storm drainage control No proper medical waste disposal
