Food Waste to Compost
Food waste disposed of in landfill releases methane, a greenhouse gas that is much more potent than carbon, but when converted into compost and applied to the land it sequesters carbon, making it an integral part of a Net Zero strategy.
Transforming organic waste into compost reduces costs as well as GHG emissions associated with your business.
The Demeterra Range of Composters
The Demeterra composters accept all types of biowaste including cooked and raw foods, meat and fish, manure, citrus fruits, wooden crates and cardboard. The temperature controlled process eliminates any pathogens and the system meets SPAn3 Health Regulations.
How does it work?
Pre-sorted organic waste and chopped wood or pellets are added to the composter
The composter mixes the materials in a temperature controlled environment at around 65° to kill any pathogens
After approximately 15 days of aerobic composting, the final compost can be removed from the Demeterra
Rest the compost outdoors or in a ventilated storage space for approximately 6 weeks before using on site.
If your business does not have gardens, consider selling the compost to gain a new income stream, or donate the compost to local farmers, community garden groups, your staff or others that can make good use of it.
