A Journey to Environmental Excellence


On 2 May 2014, The Hong Kong Polytechnic University has received a Certificate of Merit for the Public Organizations and Utilities Sector of the 2013 Hong Kong Awards for Environmental Excellence (HKAEE) to recognize the efforts paid by all PolyU members in building a sustainable campus. In addition, a joint project titled "An inline hydroelectric generating system in confined condition for urban water pipelines" developed by PolyU's Department of Building Services Engineering and Water Supplies Department also received a Certificate of Merit in the Green Innovations Award of the 2013 HKAEE.

Since 2008, HKAEE has been established to encourage and recognize organizations in eleven different industry sectors who have adopted green management and innovations. In 2013, there were a record number of 896 organizations joined the contest and each organization has to undergo stringent assessments before winning an award. PolyU was among these organizations to benchmark our environmental performance.

Commitments in Fostering Campus Sustainability

PolyU has long been committed to fostering campus sustainability. Over the years, the University had invested a lot of effort and resources in greening our campus buildings and student hostels. In 2011, PolyU has set up a Campus Sustainability Committee to promote sustainability in planning, development and operation of the campus environment, facilities, as well as develop sustainability-related initiatives in various aspects. The committee is currently devising new policies on campus sustainability, energy conservation, green procurement, waste management, water conservation and campus development. Soon after the establishment of new policies, the committee will start working on the corresponding guidelines, specifications and targets. In 2013, another Campus Sustainability Committee was also established under College of Professional and Continuing Education (CPCE) to look after campus sustainability matters for the two extended campuses of PolyU in Hung Hom and West Kowloon.

Green Campus Developments

PolyU is conscious and focuses on green building initiatives. Our Campus Development Office (CDO) and Facilities Management Office (FMO) are working hard in retrofitting existing building utilities with energy efficient systems and building new green campus buildings to improve the overall environmental performance of our campus. In light of these efforts, our extended campus in Hung Hom Bay had received Hong Kong BEAM Platinum award a few years ago and also the Homantin Hall of Residence was the first student hostel among local universities to receive Hong Kong BEAM Platinum award.

For new developments, a lot of environmentally friendly features have been included in the design, such as green decks, sun shades, evaporative cooling, heat recovery systems, energy efficient chiller systems and other energy saving facilities. You can find more descriptions of these green features for the new buildings in the Sep 2013 issue.

Healthy and Comfortable Indoor Environment

PolyU is also very cautious and endeavors to maintain good indoor air quality (IAQ) such that healthy and comfortable indoor environment is provided to our students and staff. Good or Excellent Class under the Indoor Air Quality Certification Scheme has been achieved in most areas of PolyU including but not limited to the library, auditorium, offices, classrooms and public areas. Besides, every time when you step into classrooms or lecture theatres, you will easily notice a green signage prepared by FMO providing all the green features that have been installed, including energy saving light fixtures, occupancy sensors, CO2 sensors.

Waste Collection & Recycling

PolyU is also keen to promote waste reduction, source separation and recycling. Collection bins for waste paper, plastic, metal, glass beverage bottles, rechargeable batteries, printer cartridge and food wastes are set up on main campus. At student hostels, apart from majority of the aforesaid, we also have collection arrangements for old clothes and usable items.

The Pursuit of Low-Carbon and Healthy Culture

Apart from the hardware, PolyU also encourages students and colleagues to pursue green and healthy lifestyle, e.g. saving energy, reducing carbon emission, cutting waste generation, enjoy walking and vegetarian food, etc. Every year, PolyU organizes the Campus Sustainability Weeks to highlight certain environmental issues and through a series of activities including forum, seminars, workshops and visits, etc., to raise awareness on environmental protection. Besides, different campaigns and promotional programs are organized throughout the year to remind and encourage everyone to pursue healthy and green lifestyle.

Besides, PolyU has about 70 Departmental Environmental Coordinators, who will be helping offices to look at their office environmental issues and provide feedbacks to the University.

Our students are also actively participated in promoting green culture. For example, we have students from The Green Society, HKPUSU; Green Green Hall Community, PolyU Student Halls of Residence (Hung Hom); and Green Hall, PolyU Student Halls of Residence (Homantin), who have contributed continuously in energy saving, waste reduction, etc. among their communities.

Sustainability-related Education and Knowledge Transfer

As part of the green education, PolyU has included lots of environment or sustainability related elements into the undergraduate and postgraduate curriculums and also general university requirements. Academic researches and knowledge transfer are providing us opportunities to contribute to the society. Our service learning subjects also provide valuable chances for students to personally experience how different sectors of our society are working towards a sustainable future.


In receiving the Certificate of Merit (Public Organizations and Utilities Sector) of the 2013 HKAEE, PolyU's commitment in green management practices and contribution in environmental protection has been recognized. PolyU understands pursuing campus sustainability is a continuous process and will take every opportunity to further improve the performance.

Resources Conservation

PolyU Plastic Bottle Recycling

Over the years, Facilities Management Office (FMO) has set up recycling bins on campus to promote waste source separation and recycling. Particularly for plastics, all collected plastics are handled by Yan Oi Tong EcoPark Plastic Resources Recycling Centre, which is funded by the Environment and Conservation Fund (ECF). ECF was set up under the Environment and Conservation Fund Ordinance (Cap. 450) in 1994 to support educational, research, and other projects and activities in relation to environmental and conservation matters. In which case, we can be sure our plastic bottles are recycled properly instead of going to landfills.

Each plastic bottle consists of different plastic parts. We could also help out the recycling process by following the four steps below:

  • Step 1: Remove the bottle caps
  • Step 2: Empty, rinse and dry the bottles
  • Step 3: Remove the labels
  • Step 4: Place the plastic bottles, caps, and labels into the plastic recycling bins

More information about the locations of plastic collection bins on PolyU campus can be found from FMO's website at

PolyU Glass Bottle Recycling

Glass beverage bottles are also valuable resources. Currently, all waste glass beverage bottles on campus are collected by Hong Chi Association who has launched the Glass Bottle Recycling Campaign in 2010 with the funding support from The Hong Kong Jockey Club Charities Trust.

All glass bottles collected on campus will then be taken to a factory for the production of eco-blocks (eco-blocks are invented by PolyU). Other than relieving the pressure on landfills, certain generations of eco-blocks can help to remove pollutants from the air.

On 19 May 2014, Hong Chi Association has organized a road show on campus to introduce their Campaign to our students and staff. Details of the Glass Bottle Recycling Campaign can also be found in Hong Chi Association's website at

PolyU Food Waste Recycling

According to Environmental Protection Department's 2012 Waste Statistics, Hong Kong people have thrown away an average of 3,337 tonnes food waste per day to landfill, equivalent to the weight of about 67 hundred thousand bags of 5 kg rice.

Since December 2013, PolyU has commissioned a food waste collection and recycling contractor, the Hong Kong Organic Waste Recycling Centre (HKOWRC), to collect food waste at all catering facilities on the main campus, extended campus in Hung Hom Bay and Student Halls of Residence (Homantin). We are pleased to learn that Staff Club Restaurant and Hall Restaurant at Student Halls of Residence (Hung Hom) have also joined this program in this quarter. All food waste collected will then be recycled into composts and pig feeds. Colleagues from the Finance Office, Facilities Management Office and Health, Safety and Environment Office have paid a visit to HKOWRC at Sheung Shui on 23 April 2014.

Used Item Collection Campaign on 7-8 May 2014

The PolyU Staff Association (PUSA) and the Community Recycling Coop, a subsidiary of Industrial Relations Institute (IRI), have been jointly organizing the Used-item Collection Campaign since 2008. This year, the first round of collection was held from 7 to 8 May 2014 and colleagues were very supportive and brought different items from their home to the main campus. All collected items were then sold to the needies in Sham Shui Po at very low prices.

Online Thrift Shop (環保在線) Launched by Green Hall

The Green Hall, of the PolyU Student Halls of Residence (SHR) (Homantin) has launched an Online Thrift Shop (環保在線), in March 2014 as their signature program for the collection and distribution of reusable items. On every Tuesday (7:30pm - 9:30 pm) and Thursday (8:30pm - 10:30pm), students and staff are welcome to bring along their donations and consigned items to Green Hall's communal area on the 10th floor of SHR (Homantin). Any income so generated will be used to fund scholarships to recognize Homantin Halls' residents who have made the best contributions to the environmental sustainability-related activities. In April, Green Hall has integrated the auction of reusable items into their "Easter Dream Party" to promote the Online Thrift Shop and by end of June, more than 500 items were collected and some of them were sold.

Resources Conservation Activities at Student Halls of Residence (Homantin)

The Recycling Committee (led and managed by the Green Hall) has continued in this quarter with their awareness programme to inform residents about the locations of collection bin on different floors of the building.

A reusable item collection program was also conducted during the mass check-out in the end of May. A set of four big boxes were arranged at the lounge of each hall. Residents were very supportive and donated their reusable items, including books, plastic products and cooking utensils, etc., to the program.

Recycling Competition of Student Halls of Residence (Homantin)

To encourage PolyU students to practice municipal solid waste (MSW) source separation, Student Halls of Residence (Homantin) has organized a recycling competition from 17 March to 25 May 2014 and also set up individual and group awards to reward those students who have actively participated in it. Altogether, we have over 80 winners being awarded.

Public Consultation on Future Fuel Mix for Electricity Generation

The existing coal-fired generating units for the electricity generation in Hong Kong will start to retire from 2017. In order to meet future electricity demand, the Government has launched a three-month public consultation from 19 March to 18 June 2014 on the two future fuel mix options for electricity generation for Hong Kong.

Existing Situation in 2012
In 2012, coal accounted 53% of the overall fuel mix in Hong Kong, followed by nuclear electricity imported from the Mainland (23%), natural gas (22%), and oil and renewable energy (2%).

Option 1 - Grid Purchase
The first option is "grid purchase", which increases the share of importing electricity from the Mainland to about 50% of demand.

Option 2 - Local Generation
The second option is "local generation", under which increases the share of natural gas of local generation to about 60% of demand.

Solar Powered Air Conditioning System for Vehicles Developed by PolyU

The Solar-powered Air-conditioning System for Vehicles (SAV) was first developed by Prof. Eric Ka-wai CHENG, Department of Electrical Engineering of PolyU and launched in 2009. The system derives power from solar photovoltaic and stores in a battery. SAV can be used in any vehicle to provide electricity for air conditioning even when the engine is switched off. In the 3rd generation, a six-hour sunlight exposure could provide around 6-hour air-conditioning during idling. In August this year, PolyU will launch the 4th generation, which will greatly reduce 70% of solar panels' thickness to 1.5 millimeter and increase energy conversion efficiency by more than one-third.

Antarctica May Disappear in the Next 200 Years

Researchers at Utrecht University and the British Antarctic Survey published a new paper about the Antarctica on 30 January 2014 in the Journal of Glaciology. They found that the reduction of snow cover on ice shelves caused by global warming is posing a risk to other ice shelves which could disappear in the next 200 years.

"If we manage to keep global warming below the European Union target of 2oC, more than half of the ice shelves could be saved, compared to no action taken on emissions reductions," said Dr Peter Kuipers Munneke, the paper's lead author.

This tragedy could be avoided. It may not be too late for us to start the low-carbon lifestyle and do something to slow down the global warming.
