DCEB students sweep top awards at the Green Challenge Competition 2014
Singapore has aimed to move beyond just being clean and green and towards attaining environmental sustainability. To achieve a greener and more sustainable city in the future, Singapore has been encouraging our people to develop products that are efficient yet reduce resources and wastes and without polluting our environment.
3 Teams, consisting of 15 students from Diploma in Civil Engineering with Business (DCEB), shined in the Green Challenge competition 2014 by winning the Gold and Silver awards as well as the Merit prize respectively. They have clearly exhibited remarkable Green initiatives and innovations in each of their projects that aligned with Singapore’s aim of being a sustainable city
Students of each team have put on their Green thinking caps and developed products that aimed to reuse, recycle and reduce. Their inventive products are both beneficial and functional and will help Singapore work towards a more sustainable future.
The team that was awarded Gold in the green challenge competition has impressed the judges with their simple yet impressive “smart toilet system” that is designed to recycle “grey water” from the wash basin to be used to flush the toilet. Their project titled “A button away to save water” is a smart toilet system that encourages each household to reduce the reliance on PUB water supply - this reduces the clean water wastage by at least 50% and also their monthly water bills. This system has high water saving efficiency, is versatile and low installation cost.
The team that was awarded Silver in the green challenge competition has impressed the judges by creatively using Ground Granulated Blast Furnace Slag (GGBS), a by-product from the blast-furnaces used to make iron, and fly ash. GGBS is a powder-type product obtained from burning pulverized coal in Tuas Power plant, to replace a substantial portion of the Ordinary Portland Cement (OPC) content.
The green Concrete developed by this project is a sustainable construction material which saves energy and the environment by reusing the wastes and reducing environmental air pollution. Results reveal that manufacturing one ton of green concrete developed by this project will cut down CO2 emission by up to 80% compared to the traditional concrete using pure OPC cement.
The team that was awarded the Merit Prize in the Green Challenge competition aspires to encourage every household in Singapore to contribute to foodwaste recycling, and from this reap the benefits of organically growing their own vegetables or even fruits. They have designed and developed a convenient and user-friendly system for use in homes, for recycling foodwaste such as fruit and vegetable using earthworms, to produce organic fertilizers.
DCEB students will definitely play an important role in the future of Singapore’s sustainable development plan.
