Organic Waste Processing
Food to Feed
Close the circle in the food chain
If food waste was a country, it would be the world's 3rd largest emitter of CO2. And anywhere from 30-50% of the 4bn tonnes of food produced goes to waste from farm to table (with up to half of that at the consumer side). This is estimated to cost $2.6-4tr. Further, decomposing food in landfills releases greenhouse gases (methane) that are 25 times more damaging to the environment compared to CO2.
As an alternative to dumping waste into landfills or to composting (which is useful but is time consuming and provides a lower economic value product), we are converting household, commercial, and industrial food waste into value-added products - animal feed, fertilizer and nutrient rich liquids.
Significant amounts of organic food waste are generated by households: supermarkets; hotels; restaurants; fruit and vegetable processing facilities; fish/dairy/chicken farms; etc. In fact, up to half of the food produced is never eaten and ends up as waste.
In our solution, waste food goes through a closed loop process, converting it into animal feed pellets (customized in terms of nutritional content based on the required mineral content of each animal over their life cycle). As a byproduct, we also produce a nutrient-rich liquid which can also be used to aid plant growth.
In a separate process, we combine a portion of the organic food waste with solid manure and convert this waste stream into organic fertilizer.
Surplus manure is also fed into digesters to produce natural gas. And rather than convert this into electricity (where only a 25-35% of the natural gas' calorific energy content gets converted into electricity), we feed the gas stream into absorption chillers (which can convert 60-80%+ of its calorific value into usable energy) to make chilled water and glycol for use in refrigeration and cooling of the food produced in those facilities, as well as hot water for cleaning and disinfection of the facilities.
