T O P I C Research on Collection, Recycling and Disposal Arrangements of Domestic Waste in Hong Kong
Objective a) Serious Situation of Domestic Waste – Plastic in HK Solutions for Waste Reduction awareness of waste recycling & reduction in HK b) The Problems encountered in Waste Reduction Introduce solutions for waste pollution - The Integrated Waste Reduction Plan
Content Domestic Waste & its Situation - Vivian Solid Waste - Plastics & its Measures Pollution Problems with Disposal Plastics & its Possible Solutions - Dorothy Recycling & its Barriers - Sharon Integrated Waste Reduction Plan - Irene Barriers to Waste Reduction and its Solutions Questions & Answers - Kennie
What is domestic 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 Kong 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 Wastes They are including: Plastic Paper Metals The method to dispose them is by: Landfilling Incineration
Measures to reduce solid waste • Reuse or recycling of paper minimize waste and save resources • 2. Solving plastic waste disposal problem • The ways to solve: Reuse of plastic scrap Recycling of plastic waste As fuel in power stations Making biodegradable plastics
Pollution problems associated with the disposal of plastics Pollution Problem: Plastics Sea animals death rate Air pollution Carbon dioxide Damage the environment Acid rain
Possible solutions to pollution problem of plastics To tackle the problem of waste disposal: Special functional groups are introduced into the polymer chains chains will be broken down • Biodegradable plastics
To tackle the problem of waste disposal: (Cont’d) Direct recycling • 2. Recycling of plastics Recycling of energy Recycling of chemicals
Recyclable Materials Recycling • Paper, • Ferrous & non-ferrous metals, • Plastic, • Glass
Recycling of plastics • Direct recycling • isolated, cleaned, pulverized, and remolded • Recycling of energy • energy obtained for generation of electricity • Recycling of chemicals • products fractionally distilled to give useful chemicals.
Barriers to Domestic Waste Recycling in Hong Kong • The built environment inhibits recycling activities.Small flat sizes restrict source separation and storage practices.
Waste Recovery and Recycling • Recovery levels are high recycling in Hong Kong is market driven. • Indicates the risks in over-reliance and recycling measures.
Integrated Waste Reduction Plan • Waste Avoidance, Minimisation and Materials Recovery Programme • b) Institutional Programme • c) Bulk Waste Reduction Programme • d) Construction and Demolition Waste Management
Flow Diagram of Main Collection of Municipal solid Waste in Hong Kong Municipal solid Waste Arising at Source Solid Waste Public / Private Refuse Collection Points Refuse Transfer Stations Landfills
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 • environmental awareness of public ↓ • ∵ Charges for collection are not linked with the quantity of waste. ∴ Nofinancial incentive to reduce the quantity of waste. • no legal basis to make regulations.
(d) Low values for recovered materials (e) The predominance of SME inhibits waste reduction investments (f)Basel Convention
Questions: Domestic Waste Collection How much domestic waste is collected by the Food and Environmental Hygiene Department? About 6,090 tonnes of domestic waste, 1,340 tonnes from Hong Kong Island, 1,920 tonnes from Kowloon, 2,830 tonnes from New Territories and outlying islands.
2. When would the refuse collection service be suspended? On the first day of the Lunar New Year
3.Where are the domestic waste disposed? Delivered to refuse transfer stations or landfills managed by the Environmental Protection Department.
Does the Environmental Protection Department have any plan to expand the current waste reductionactivities? Questions: Recycle, reuse and reduce Explore more locations for placing recycling bins Support waste reduction activities
2.How does the Environmental Protection Department support waste reduction activities? recycling bins • separate collection of 3 common recyclable wastes organized "Waste Paper Recycling Scheme in Schools" supported various recycling projects organized by green groups and private sectors.
