The detection process takes 15 to 30 minutes, and sample preparation is necessary, making it impossible to perform real-time monitoring and provide early warning signals. Prof Hao says, ‘This system is simple to use and it takes less than three minutes for each testing. With high accuracy and low installation cost, the system enables online real-time and consistent monitoring to ensure that the fermentation system operates efficiently and provides early warning signals.’ The research team has deployed the system in multiple projects, including hydrogen sulphide monitoring at Siu Ho Wan Sewage Treatment Works in Hong Kong, alkalinity and hydrogen sulphide monitoring at Tung Chung Sewage Pumping Station in Hong Kong, Macao Household Food Wastes-Sewage Sludge Co-digestion towards Energy Recovery, and Characterization and Energy Recovery Potential Evaluation of Macau Commercial Food Waste (Phase I and II). The prototype components of the system have undergone laboratory tests and validation and have been used in real-world settings. Currently, the team is negotiating with several environmental engineering companies and venture capital firms regarding potential partnerships. Supporting Student Entrepreneurs in Environmental Protection BioPeTech is a company founded by a group of UM students that specialises in producing a natural, eco-friendly, and high-quality malt cat litter from brewer’s spent grain (BSG), a by-product of the beer brewing process. During their studies at UM, the students received technical guidance from their residential college and support from the Centre for Innovation and Entrepreneurship, a national co-working space at the university. The company has entered partnerships with Funny Eye Brewery, the first craft brewery in Macao (established by another entrepreneurial team from UM) and Mak’s Brewery in Hong Kong, and established close cooperation with these companies to recycle malt residue, machinery, and staff management. The goal is building a circular economy in the beer brewing industry. It all started with a deep love for cats and a creative idea. The core members of BioPeTech, Tam Pui Si, Tong Man, Fu Haoming, and Wang Cheng-hao, first met at Cheng Yu Tung College (CYTC) of UM and found that they shared a common interest in entrepreneurship even though they majored in different disciplines. They came up with the idea of using malt residue from beer brewing to create BSG cat litter. With College Master Wong Seng Fat and Resident Fellow Tang Yu Ming of CYTC serving as advisors, and under the guidance of Associate Professor Tam Kin Yip in the Faculty of Science and Technology, the team developed a technology called sugar phagocytic fungus. This technology helps eliminate sugar from malt residue to prevent kittens from consuming sugar by accident, creating a unique formula for the BSG cat litter. 澳大學生開發的環保麥芽貓砂 The eco-friendly malted cat litter developed by UM students
