A new lease of life for food and green waste
Turning organic waste into quality compost/soil improver
- Food and green waste is converted into soil improver rather than going to landfill
- All soil improver produced is PAS100 certified and peat free
- Uses Open Windrow Composting (OWC) and In-Vessel Composting (IVC) technology
- Contributes to the circular economy by treating waste as a resource.
Diverting organic waste from landfill – sustainable circular economy – PAS100 standard
TW Composting supports local authorities and local businesses by processing organic waste from kerbside collection and private waste management contractors. It currently manages the processing of more than 90,000 tonnes of food and green waste per year that could otherwise have ended up in landfill.
After the waste is treated it becomes a product that meets PAS100 – a British Standards Institution accreditation that means it is no longer waste. Then it’s good enough to be used as a high-quality soil improver that can be produced to different grades. This means it can be suitable for agriculture, horticulture, and domestic use, and can also be used on sports pitches.
The company is built around its highly experienced team, including waste management professionals and organics experts. TW Composting currently operates, maintains and manages composting sites and related waste management operations in Northamptonshire, Buckinghamshire, and Derbyshire.
The industrial composting process is similar to home composting but on a much larger scale.
Open Windrow Composting (OWC) – where the organic material is shredded then laid out in ‘windrows’ (long lines) to break down over time and produce compost – is used for green waste only. This treatment phase takes about six weeks, then the PAS100 product can be produced.
For co-mingled food and green waste, In-Vessel Composting (IVC) is used to sanitise the material and kill off any bugs in a temperature-controlled environment first, before it follows a similar process to OWC.
This is all about the sustainable circular economy: taking old food and green waste, making it useful, then putting it back in the soil to help grow new things.
