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

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

Special functional groups are introduced into the polymer chains chains will be broken down
To tackle the problem of waste disposal:1. Biodegradable plastics

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.
![Page 15: Integrated Studies Presentation Using PowerPoint.](https://reader035.fdocuments.us/reader035/viewer/2022081516/56649d975503460f94a80f04/html5/thumbnails/15.jpg)
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.

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.
![Page 21: Integrated Studies Presentation Using PowerPoint.](https://reader035.fdocuments.us/reader035/viewer/2022081516/56649d975503460f94a80f04/html5/thumbnails/21.jpg)
(d) Low values for recovered materials
(e) The predominance of SME inhibits
waste reduction investments
(f) Basel Convention
