From food wastes
to fertiliser
Improving the current food waste recycling rate is Westcom, a company that develops and produces equipment and products in food waste and other technology. Through its cooperation with A*STAR, Westcom developed its very own Waste-To-Fertiliser technology that reduces, converts and recycles food wastes into high quality fertiliser.
Westcom’s smallest digesters can transform 50kg of unconsumed food into 5kg of organic fertiliser in 24 hours while its largest digester can process more than 1,000kg of food waste in the same amount of time.
The global food waste management market size was estimated at US$34.22 billion in 2019. It is expected to expand at a compound annual growth rate (CAGR) of 5.4% from 2020 to 2027.
