Bring Your Own and Say No to Plastic


Lee Woo Sing College has become CUHK’s first college to completely ditch plastic straws! The College’s catering outlets will now provide paper straws only upon request by customers, and have replaced plastic stirrers with wooden ones as well. It is estimated that more than 90,000 plastic straws and 60,000 plastic stirrers would be saved each year! Further measures to ditch plastic disposables include: charging each type of disposables individually, and introducing paper takeaway lunchboxes and wooden takeaway cutlery.

Lee Woo Sing College encourages canteen customers to bring their own container and cutleries when buying take-away meal. Extra charge is required if the customers request for environmental friendly take-away containers and cutleries.

Food Waste Collection


Lee Woo Sing Collage’s canteen is the first canteen that set up a self-served food waste collection station. After meals, students have to separate their food wastes and dishes according to classification from the station. It aims to develop students’ concern on the food wastes they produced. The food wastes are collected by the appointed contractor of CPSO for further treatment and upcycle afterwards. 

Recycle Bins

Difference kinds of recycle bins/ facilities are available around the colleges. 

CCRP Programme

Lee Woo Sing College is one of the collection points registered under the scheme “Computer & Communication Products Recycling Programme” (CCRP) of Environmental Protection Department (EPD). Two recycle bins have been placed at the G/F of the college for collecting the unwanted CCRP items. Students and Staff of the college are welcome to drop the related items into the bins. For details, please refer to EPD website:

The effectiveness of recycling plastic bottom depends on the condition of the bottom being collected. It is important to keep them clean and rinsed before they are dropped into the recycle bin. 2 sets of “Clean Recycling Device” are placed at the G/F and the courtyard of the college, providing a convenient way to rinse the bottom before recycling.

Recycle Bin

To facilitate recycling at the college, recycle bins have been placed at each floor. The accessibility of the recycle bins boosts the recycling rate and cultivates the recycle habit of the hostel residents.

Treasure at LWS
Exchange Group for unwanted items

As a green college, we encourage all LWSers to follow 4R (Reduce, Reuse, Recycle, Replace) green campaign. A Facebook platform, Treasure at LWS, is therefore established to make convenience to LWSers to share their unwanted items which are still in good condition to each other. Let’s join it to pay an effort on environmental protection!
