How can we reduce the volume of disposal waste?

IncinerationIncineration

☆Volume reduced ~90%

Solid waste: 13,503 tons

Landfills Incineration2

Solid Waste Disposal Rate 16,000 tons/day (2008)1 3,000 tons/day

Area of Land Used 270 ha. 10 ha.

Construction Cost 6 billion 4 billion

Operation Cost 490 million/year (2008)1 250 million

Derived Pollution Air pollution: methane Water pollution: leachate Soil pollution: decomposition of biodegradable waste

Air pollution: dioxin & ash

Advantages -Handle more solid waste in a same time-Land reuse-Methane

-Save cost-Decrease about 90% volume of solid waste-Energy is recovered for electricity generation -Advanced technology on eliminating pollutants

Disadvantages Other Than Pollution

-Consume huge area-Landfill areas cannot reuse in short period & topsoil required regular maintenance-Non-sustainable, require to find another new site upon it filled

-Extra works required to handle the non-combustible leftovers after incineration process

Remarks: 1 & 2 – Data collected from Environmental Protection Department on 2008 Statistic. 3 – Expected performance of a typical advanced incinerator.

☆Less Disposal Waste

☆ Volume reduced by incinerator
