BillionCarbon is nutrient mining from food waste to convert to liquid bio-fertiliser concentrate, using its internet of things (IoT)-enabled micro-climate controlled bioreactor technology – developed over 2 years of R&D. Through this technology, it converts food waste to a micro-nutrient rich liquid bio-fertiliser concentrate within 3 days, producing no waste products in the process. This fertiliser is currently undergoing lab enhancements and field trials.
