RiFood co-organises workshops to promote food upcycling and reduce food waste

The Research Institute for Future Food (RiFood) recently co-organised workshops with the aim of promoting food upcycling and reducing both food waste and carbon footprints. The workshop titled “From Waste to Worth: What Is Upcycled Food and Why Should We Try It?”, held in collaboration with the School of Hotel and Tourism Management (SHTM) and the Campus Facilities and Sustainability Office (CFSO) on 10 February 2025, discussed the significance of food upcycling in minimising food waste and lowering carbon emissions. Participants also had the opportunity to try upcycled snacks. Additionally, in the “Brew-tiful Workshop” co-organised with the Food and Wine Academy of SHTM on 11 February 2025, participants explored the art of crafting beers, upcycling coffee grounds, bread and fruit into beers with unique flavours, distinct from traditional wheat-brewed varieties.

PolyU and CSD sign MOU to promote upcycling of food waste and development of eco-friendly products

The Hong Kong Polytechnic University (PolyU) and the Correctional Services Department (CSD) signed a Memorandum of Understanding (MoU) today to jointly promote the upcycling of food waste and the development of environmentally friendly products, injecting new impetus into the sustainable development of the correctional industry. The MoU sets out a framework for collaboration between PolyU and CSD to jointly promote innovative development initiatives over the next five years, including the application of PolyU’s scientific research results on food waste upcycling to industrial production in correctional institutions; and the provision of vocational training to persons in custody (PICs) in the design and production of environmentally friendly products by PolyU to enhance their employability. The collaboration not only promotes environmental protection but also assists in the rehabilitation of PICs. Witnessed by Prof. Christopher CHAO, Vice President (Research and Innovation) of PolyU, and Mr NG Chiu-kok, Deputy Commissioner of Correctional Services (Rehabilitation and Management), the MoU was signed by Prof. WONG Ka-hing, Director of the Research Institute for Future Food and Professor of the Department of Food Science and Nutrition of PolyU, and Mr TONG Soen, Assistant Commissioner of Correctional Services (Rehabilitation). Prof. Chao said at the ceremony that PolyU has been tackling social challenges and promoting sustainable development through innovative research and translating research outcomes over the years. The “food waste-derived 3D printing material” patented technology covered in the collaboration project was developed by PolyU’s Research Institute for Future Food, which opens up a new way to tackle the problems of municipal food waste and greenhouse gas emissions in Hong Kong. Both parties will work together to create a mutual aid ecosystem, where new economic, ecological, and cultural value can be generated, contributing to the realisation of a cohesive society and sustainable development. Addressing the ceremony, Mr Ng said that the CSD has been committed to introducing green measures in correctional work to build an integrated and sustainable correctional system. The signing of the MoU marks an important milestone in the sustainable development of correctional work. The first phase of the collaboration involves the application of PolyU’s patented technology for making 3D printing material with spent coffee grounds to the industrial production work performed by PICs. PolyU will also provide vocational training in product design for PICs to develop more environmentally friendly spent coffee grounds products. The environmentally friendly spent coffee grounds products will be available for sale on the CSD Sports Association's online charity gift sales platform, Made In Prison, to promote messages of supporting rehabilitation and environmental protection to the public. All proceeds from the sale, after deducting necessary costs, will be donated to various local registered charities, providing PICs with opportunities to contribute to the community.

Ir Prof. POON Chi-sun featured in short documentary film “Carbon Revolution in China”

Ir Prof. POON Chi-sun, Director of Research Centre for Resources Engineering towards Carbon Neutrality (RCRE), Head of Department of Civil and Environmental Engineering, Michael Anson Professor in Civil Engineering and Chair Professor of Sustainable Construction Materials, was featured in the short documentary film “Carbon Revolution in China”, to introduce the Eco-blocks developed by his team. It is a type of green construction material produced from construction and other waste materials, and can absorb carbon dioxide and store it permanently, thereby reducing greenhouse gas emissions. The short documentary film produced by the Hong Kong Coalition features efforts in mainland China and Hong Kong aimed at carbon reduction and energy saving, telling good stories of the Nation’s advances towards its “dual carbon” goals.

Prof. Nathanael JIN writes commentary on microbial risks of plastic pollution for Nature

Prof. Nathanael JIN Ling, Member of the Research Institute for Future Food (RiFood) and the Research Institute for Sustainable Urban Development (RISUD), and Assistant Professor in the Department of Civil and Environmental Engineering and the Department of Health Technology and Informatics, was invited by Nature to contribute a commentary titled “What harmful microbes are lurking in the world’s 7 billion tonnes of plastic waste?”. In the paper, Prof. Jin and his team highlighted the microbial risks associated with plastic pollution and proposed a global strategy to address these challenges. Plastic debris creates a new ecological niche for microorganisms, forming a new ecosystem known as the “plastisphere”. The paper outlines the potential risks of plastisphere microbiomes pose to ecosystem functioning and the health of humans and other organisms. To develop a comprehensive global strategy, the paper suggests six priorities: quantifying effects, redefining plastic pollution, sustaining funding, establishing expert panels, adjusting management strategies and protecting people.
