What is domestic What is domestic waste?waste?

Domestic waste is the waste that produce through the family active.

Types of domestic waste: Plastic Paper Paperboard Glass

Situation of Domestic Waste in Hong Situation of Domestic Waste in Hong KongKong

More than 1 million tonnes of MSW in Hong Kong.

The major kinds of recyclable wastes recovered included:

•Paper•Plastics•Ferrous metal•Non-ferrous metal

Solid WastesSolid Wastes

PaperMetals

LandfillingIncineration

PlasticThey are including:

The method to dispose them is by:

Measures to reduce solid waste

1. Reuse or recycling of paper minimize waste and save resources

Recycling of plastic wasteAs fuel in power stationsMaking biodegradable plastics

2. Solving plastic waste disposal problem The ways to solve:

Reuse of plastic scrap

Plastics

Pollution problems associated with

the disposal of plasticsPollution Problem:

Air pollution

Sea animals death rate

Carbon dioxide

Acid rain Damage the environment

Possible solutions to pollution

Barriers to Domestic Barriers to Domestic Waste Waste Recycling in Hong Kong Recycling in Hong Kong

•The built environment inhibits recycling activities. Small flat sizes restrict source separation and storage practices.

Waste Recovery and Waste Recovery and RecyclingRecycling

• Recovery levels are high recycling in Hong Kong is market driven.

• Indicates the risks in over-reliance and recycling measures.

Waste in Hong Kong

Solutions of Domestic Waste Collection

• 1st stage: Transfers domestic waste from disposal points to

– a refuse collection point (RCP) at street level; or

– a refuse storage chamber within a housing estate.

• 2nd stage: Collects this waste and transfers it to final disposal points.

Barriers to Waste Reduction in Hong Kong

(a) environmental awareness of public ↓

(b) ∵ Charges for collection are not linked with the quantity of waste.

∴ No financial incentive to reduce the quantity of waste.

(c) no legal basis to make regulations.

(d) Low values for recovered materials

(e) The predominance of SME inhibits

waste reduction investments

(f) Basel Convention
