Researchers at the National University of Singapore have developed a sustainable anaerobic recycling system that can convert food waste into electricity, heat and fertilizer.
According to Science Daily, working with this stable system is very simple and requires less maintenance compared to other methods and provides maximum efficiency and security.
Remarkably, this system is able to convert about 80% of food waste into a nutrient-rich sap that can be converted into liquid fertilizer for agriculture and horticulture in another process.
This system is equipped with sensors that announce the end of each stage of the work, and in case of any security problem, they notify the experts in real time using smartphones and landlines.
An anaerobic recycling system functions similar to a biochemical digester that decomposes organic matter in an oxygen-free environment.
Using a combination of anaerobic microorganisms, this system converts food residues into biogas, which can be converted into heat and electrical energy.
By using the heat from this process, the hot water required to maintain the temperature of the decomposition tank at about 50 degrees Celsius is prepared. Also, the control system, sensors, motors, pumps, fans and all the components of this system operate using electrical energy resulting from the operation of the system. This system is able to produce between 200 and 400 kilowatt hours of electrical energy from each ton of food waste.
Researchers are building a portable prototype of this system, which is supposed to be launched inside a 6-meter container and used as a mobile system in areas where there is an urgent need for food recycling.
GAIN Inc. also has plans to accompany waste conversion projects
GAIN Inc., as one of the new collections in the recycling sector, by supporting the waste-to-energy project in various Canadian cities such as Vancouver in British Columbia, Winnipeg in Manitoba, Toronto in Ontario and Montreal in Quebec, plans the same is in hand for execution.
Due to the high return on investment, these methods have the ability to attract large capitals, and it is a win-win move between investors and producers, in addition, these new methods can play a major role in improving the process of energy supply in high-consumption countries such as the United States and Canada.
