We are able to compost not only food and green waste but also compostable packaging.

What is compostable packaging?

Quite simply, compostable packaging is packaging which is made from plant-based, recycled materials which, when processed correctly, can be returned to earth as compost or soil improver. It provides an environmentally friendly alternative to single use plastic.

How is compostable packaging processed?

We use industry-leading in-vessel composting technology and ever-evolving processes developed over more than 30 years to process organic waste in the most efficient, safe, cost effective and sustainable manner to produce a high-quality end soil improver. Our flagship Cambridge site utilises a computer-controlled double-ended batch tunnel in-vessel system, capable of safely composting all manner of materials including compostable packaging.

Compostable packaging, food waste, green waste and specific organic waste collected from homes and businesses is delivered to our site in Cambridgeshire. This waste is then shredded and blended to produce a homogeneous mix for composting. Blended material is loaded into the in-vessel bunker system, which features an aeration system, temperature control and wireless data logging probes to decompose it in a controlled manner which meets EU composting standards.

The system processes the waste in a fully-enclosed computer-controlled environment. Once the tunnels of the in-vessel bunker system are filled and the doors are closed, fans blow air through the perforated floors of the tunnels. The air passes through the composting material and is re-circulated within the tunnels. When the oxygen level within the tunnel drops below a minimum set level, fresh air is drawn in, allowing very tight control of oxygen levels and temperature within the material.

Following the in-vessel stage is the stabilisation phase where the compost is arranged in rows and turned on a regular basis with a dedicated turner.  After 6 to 8 weeks the material is ready for screening into a peat free high quality PAS 100 compost.
