New Machine Turns Food Waste into Compost

The organic waste composting system processes food scraps, meat products, peelings, fish waste, soft bones, and most other left-over foods, as well as compostable cardboard and food packaging, turning everything into nutrient-rich compost in an estimated 24 hours.

The unit is installed at the food waste source, which should eliminate the need for transportation and help reduce the carbon footprint.

The system comprises a main composting unit, where the chamber has internal rotating arms that mix the compost, with airflow being introduced via a ventilation fan.

Micro-organisms are introduced to the chamber, in conjunction with the microbes from the food waste, which are activated and multiply under regulated temperatures of 50˚C or higher, which is said to pose no threat to humans or animals.

For hygiene, the temperature of the tank is raised to 70˚C, for one hour at the end of the composting process, to eliminate all harmful bacteria.

A deodoriser complements the composting machine by absorbing and reducing foul odours, providing an odour-controlled environment.

Additional food waste and compostable material can then be added, and the process repeated; however, unloading of the composter should only occur once every 1-3 weeks.

The resulting compost should be nutrient-rich and can be used in various horticulture applications in a 1:10 compost to soil ratio. It can be used in gardens or horticulture applications as fertilizer to grow a variety of crops.
