Green Delight in Estates

The Hong Kong Housing Authority (HA) has partnered with green groups to launch the long-term community environmental programme "Green Delight in Estates" (GDE) since mid-2005. The programme aims to raise the environmental awareness of Public Rental Housing (PRH) residents and instill a culture of protecting and improving the environment. It was rolled out in phases to ultimately cover all PRH estates under HA. The themes of these programmes included waste reduction/recycling, waste separation at the source, estate greening, reducing the use of plastic bags, building up green infrastructure, promoting green practices, etc.

GDE Phase 12 (January 2019 – January 2021)

“Waste Reduction and Recycling” is the theme of GDE Phase 12 which will last for two years. 40 PRH estates have been selected for each year to participate in the in-depth educational and promotional programmes. The partnering green groups are Greeners Action, Business Environment Council and World Green Organisation. The launching ceremony-cum-green carnival was held on 13 April 2019 at Oi Man Estate. The green carnival including second-hand barter markets, upcycling and eco-detergent workshops were well received by PRH residents; whilst the briefing sessions for EMAC members were also smoothly conducted.

Second Cycle of GDE – Phase 6 to 11 (2012-2018)

The second cycle of GDE was completed in 2018. Partnered with the Business Environment Council, Friends of the Earth (HK) and the Conservancy Association, a total of 176 PRH estates were covered. Highlights of the programme are as follows:

GDE Phase 11 (October 2017 – October 2018)

"Green Junior's Academy on Waste Reduction" is the theme of this year's GDE Phase 11 community environmental education programme. The highlighted programme, "Finding Green Junior", has been commenced since December 2017. Mascot Green Junior has taken a proactive role in engaging residents in waste reduction and recycling messages through year-round activities such as greeting residents of PRH estates and teaching fans on proper and clean recycling. These activities aim at raising residents' awareness of waste reduction and recycling as well as encouraging them to reduce and save resources in their daily lives.

The slogan competition was launched in June 2018 and the result was announced in August 2018. The champion of the Open Group is “回收常減廢 環保免徵費 消費肯節制 惜食顯智慧” and the Junior Group is “減廢回收無難度 綠色屋邨我締造”. A total of 2,647 volunteers have been recruited as Green Estate Ambassadors in Phase 11 GDE programme.

It aimed to encourage residents to review their household waste by category as well as by quantity and to reduce their household waste by adopting various green measures. We also extended our educational programme to selected commercial centres to promote waste reduction including food waste.

Reducing Food Waste Campaign

To advocate eating light and food waste reduction, a range of initiatives were introduced under GDE Phase 7. An estate-wide campaign, "Empty Your Plate Campaign", was launched from 30 September to 20 October 2014 to encourage residents to reduce food waste. The participants pledged themselves to "Zero Food Waste" by ordering and preparing meals appropriately, so as to empty their plates upon finishing each meal. An "Eat Light, Eat Right" Poll was organised from March to April 2014 to promote green tips on food preparation through posters, pamphlets and website. A two-minute video named "Go Green. Eat Light. So Easy!" was produced and broadcast at Housing Channel from August to October 2014.

On-site food waste recycling using micro-organism was adopted in Lam Tin Estate. In addition, another round of glass bottle recycling was launched in ten other estates. Workshops were held to educate residents in creating art and decor from waste bottles. The remaining bottles were delivered to a glass recycler making paver blocks.

GDE Phase 6 (June 2012 - June 2013)

Riding on the success of the first cycle, a new phase of the GDE programme with new activities and themes was launched in June 2012 to continue our environmental works in PRH estates. In line with the government's latest environmental initiatives, the theme for Phase 6 of the GDE is "Reduction of Municipal Solid Waste". An estate-wide campaign to promote green messages on saving food as well as a series of in-depth educational and promotional programmes on food waste reduction in selected estates have been organised. Food waste recycling and glass bottle recycling programmes were carried out in selected estates during this phase.

Reducing Food Waste Campaign

In order to promote the message on saving food, we conducted an estate-wide programme, "Cherish Food with Rewards" Campaign, in all HA PRH estates from 15 October 2012 to 4 November 2012. Tips on reducing food wastage were promoted through posters and website. Residents were encouraged to make pledges on saving food.

A "Food Waste has Value" Green Recipe Competition was held from 18 February to 17 March 2013 to solicit smart cooking recipes from residents on reducing food wastage. Around 100 participants including the competition winners and their families, representatives from HA and green groups participated in the final judging and award ceremony held in May 2013. The Secretary for Transport and Housing, together with the Secretary for the Environment, shared their food saving tips with the participants. They had also demonstrated how to cook spring rolls from left-over cooked ingredients of Chinese soup.

Food Waste Recycling in Estates

Food waste recycling was carried out in six selected estates in 2012/13. On-site food waste recycling for compost using micro-organism has been conducted in Lam Tin Estate since December 2012. Off-site food waste recycling was commenced in November 2012 for Lai Kok Estate, Tin Wah Estate and Tin Tsz Estate, and in December 2012 for Nam Shan Estate and Ching Ho Estate. Food waste was transported to a centralised food waste recycler in Yuen Long for conversion mainly into fish feed. As at the end of March 2013, 875 households have registered to participate in the scheme.

Regarding the food waste collection process, either a self-help mode or "Bucket Exchange" mode was adopted in the six estates. Tin Wah Estate, Tin Tsz Estate and Nam Shan Estate adopted the self-help mode whereby the residents put their food waste directly into large bins for collection by the food waste recycler. For Lai Kok Estate, Ching Ho Estate and Lam Tin Estate, "Bucket Exchange" mode was adopted whereby the residents brought their buckets of food waste to the ground floor of each block to exchange for clean buckets from the security guards.
