Power up a thousand lightbulbs with your leftover 剩食亮千燈

Though transforming food waste into biogas is not any new discovery, it is still encouraging to see Asian students taking the lead to combat campus food waste at the same time generating green energy for lighting up the school.

Apart from IIM-Bengaluru graduates Sreekrishna Sankar and Mainak Chakraborty implementing it in 2015, now the Asian Institute of Technology (AIT) campus in Bangkok also developed their own food digester to turn campus leftovers into electricity which is enough to power 1,000 15W LED light bulbs for 12 hours.

They started by collecting the food waste from the central AIT cafeteria, then transporting them to the project site to process. The advance development in this project is the incorporation of a centralized monitoring system which can send real-time data to a central monitoring authority. This can help to monitor the temperature, acidity and oxidation-reduction potential of the plant along with the quality of biogas from a PC anytime, anywhere.

In the future, they are looking for to be adopted on a larger scale, community-based biogas plants serving university campuses, hospitals, and the communities with linked to the Internet of Things.

雖然化剩食為生物氣體並不是什麼新發現,但由亞洲學生主導以對抗校園剩食為目標的發電計劃,仍令人感到鼓舞。

最近位於曼谷的亞洲理工學院校園亦有團體發明了他們的剩食回收處理機,把剩食轉為電力,可連續 12 小時點量一千個15瓦耗電的 LED燈泡。

他們首先於學校的食堂收集剩食再運輸到項目點進行處理。今次項目加入了一套中央監控系統,可以實時傳送數據至中央監控中心。以監察溫度、酸度及氧化等的變化,任何時間、任何一部電腦也可監察製成的生物氣體的品質及製作過程。

未來更會善用物聯網技術(IoT)為大學校園、醫院、社區,去建構更龐大的社區生物氣體工場,滿足更大需求。
