Clay is a naturally occurring material composed mainly of fine-grained minerals, demonstrating plasticity through a range of water content. Given the low recycling rate of food waste in Singapore (18%), incorporating food waste in existing clay products presents an opportunity to conserve natural resources and develop more sustainable clay materials. This technology involves the development of food waste-incorporated clay, which permits safe biodegradation over time without the use of kiln firing. A selection of food waste is carefully treated and blended into the clay to create sustainable clay with high waste content, high nutrients, great workability, and appropriate shelf-life. Each type of food waste contributes different physical and chemical properties to the clay, affecting its biodegradability and workability. Apart from food waste, a naturally occurring binder is also added to ensure overall biodegradability. By adjusting the formulation of the food waste-incorporated clay, its appearance and other functional properties (such as strength and workability) can be made comparable to conventional clay, with the added benefit of nutrient (calcium, potassium, nitrogen, carbon) leaching capabilities. This creates sustainable, biodegradable clay for various built environment applications. The technology owner is interested in working with companies seeking sustainable clay materials on joint R&D projects, out-licensing and test bedding opportunities .

Access to clean and safe drinking water is essential for health, yet millions of people worldwide still lack this necessity. According to the World Health Organization (WHO), over 2 billion people globally use drinking water sources contaminated with feces, leading to severe health consequences. Unsafe water, along with inadequate sanitation and hygiene, is estimated to cause 485,000 diarrheal deaths each year. Water purification technologies face significant challenges, especially in decentralized systems lacking the efficiencies of large-scale operations. They often have a substantial carbon footprint due to energy-intensive processes and reliance on chemicals. Existing portable devices primarily use filtration and have a limited lifetime on-site, with little opportunity for cleaning to restore its performance.  Developed by a research team, this technology effectively addresses the above challenges by employing electrochemical methods that generates strong oxidizing agents to kill micro-organisms present in raw water and potentially degrade organic pollutants that conventional portable reactors cannot remove via filtration. Due to its working mechanism, the device is self-cleaning and does not need regeneration. By harnessing solar energy and activated carbon, this chemical-free purification approach is not only environmentally friendly but also perfectly suited for deployment in remote areas, developing countries, and disaster-stricken zones where traditional water treatment infrastructure is lacking. The technology owner is looking for collaborations with local SMEs to co-develop scaled systems and deploy it through disaster relief organizations, government agencies and non-profit organizations in selected developing countries. 

Cooking oil waste has become a significant environmental problem in recent years.

Plastic recycling plays a crucial role in achieving a sustainable future. Proper sorting of waste plastics is essential, especially in mixed waste streams where various materials are combined. Some types of plastic are not recyclable, and even recyclable ones can be difficult to separate efficiently. Sorting mixed waste streams into different recyclable categories can be time-consuming and labour-intensive, especially for materials with similar appearances, such as different types of plastic. To address these challenges, this technology aims to automate and accurately sort plastic waste, reducing the reliance on manual processing and improving overall plastic recycling efficiency. The technology on offer is a patented artificial intelligence (AI) based material sorting robot that sorts plastic waste accurately. Comprising of a camera, recognition unit and analysis unit, each unit of this system can continuously identify and sort waste plastics and generate information in real time. Blower vacuum adsorption devices are placed within each unit to pick waste in a speedy and accurate manner. This technology effectively reduces the issue of labour shortage in the waste sector, lowers operating costs and contamination rates that hinders recycling efforts. Currently, the technology has been deployed successfully in South Korea to sort polyethylene terephthalate (PET), polyethylene (PE) and polypropylene (PP). The technology owner is interested to work with Singapore waste collection companies on joint development projects to testbed this technology and improve plastic recycling rates.
