Composting Program - Overview

There is no regulation in Hong Kong to make separating food waste compulsory, but there are food waste recycling programs available for F&Bs or households to join on a voluntary basis.

3 Steps Food Waste Recycling 

1. Separation

  • Pre-consumer food waste 

    • animal food waste

    • vegetable food waste

    • waste from industrially-processed food

  • Post-consumer food waste

    • leftover food

    • Unfinished ordered food

  • Removal of plastic packaging and utensils

 

2. Collection

  • Food waste vehicles managed by HKSAR Government (Organic Waste Treatment Facilities)

  • Centre: Siu Ho Wan

 

3. Recycling

  • low-carbon method

    • Process 100–300 tonnes of food waste per day

    • Produces biogas

    • Able to provide 14 million kWh of electricity to Hong Kong's power grid every year ( equivalent to power 3000 households)

  • Convert food waste into succinic acid by using enzymes and bacteria

    • Process animal feed, fertilizers, cleaning products

Daily Food Waste Recycling Service

  • 24h recycling services to livestock breeders, farmers, F&B, schools, and large-scale estates

  • Recycle to process compost

Currently, no legislation dictates the necessity to separate food waste from other solid wastes. In 2012, up to 3 thousand tonnes of food waste is thrown out daily (36% of HK waste). A third is derived from Commercial and Industrial sources (restaurants, hotels, markets, processing plants, etc)

 

The practice of throwing away biodegradable food waste is bad due to Limited space, foul odor,  leachates, and landfill gases.

Food Waste Management Strategy

​Priorities

  1. Prevention and reduction of Food waste

  2. Donation of surplus for human consumption

  3. Recycle to recover energy and nutrients

  4. Waste-to-energy treatment of Municipal Solid Waste

  5. Clean landfilling (gas capture technology)

Progression:

​(The Blueprint) Blueprint of Sustainable Use of Resources unveiled by EB in 2013

​Actionable Strategy:

  1. For the government to take action (As shown in Food Waste Management Strategy)

  2. Incentivize community to mobilize and participate in efficient waste management (Niche for GREEN Hospitality)

  3. 3. Fill missing gaps in HK Waste Management infrastructure

(The Plan) A Food Waste & Yard Plan for HK – Outline governmental plans: Reduction of Food Waste disposal to landfills by 40% by 2022 (Using the above strategy)

 

Forecasted Food Waste Management Mix

  • 55% recycled

  • 22% Landfilled

  • 23% incinerated

 

Waste Management infrastructure in HK

  • 7 Refuse Transfer Stations in HK actively used

  • 3 active Landfill sites all of which are full/near full

  • Ecopark – Innovation of using affordable land: Wood, IT, Recycling Centre, Construction Material, Metals

  • Organic Waste Treatment Facilities – Recycling food waste into RE

  • Integrated Waste Management Facilities – Modern waste-to-energy technology

  • Community Green Stations – Enhancing environmental education to engage the public to increase waste reduction and recycling

  • Sludge Treatment Facility – High-temperature incineration to treat sludge arising from sewage treatment

 

Government initiatives

  • ​Food Wise HK Campaign: Started in 2012, aim to disseminate best practices to Restaurants, Hotels, commercial food providers, etc for food waste reduction and recycling. By 2013, 450 Ambassadors recruited

  • ​Food Donation: in 2013, the Government’s Centre of Food Safety issued safety regulations for Food Hygiene pertaining to NGO

  • ​MSW Charging: The government has been debating on 2 Waste charging models

  1. Charging by designated garbage bags: All waste needs to be disposed of in properly lined bags

  2. Charging by weight-based ‘Gate-Fee’: Fee to be charged based on the weight of the garbage bag
