Green waste and commingled waste

We offer Local Authorities and waste contractors a cost-effective, low carbon, green and commingled waste management solution.

Tamar's composting division operates six in-vessel composting (IVC) and open windrow composting (OWC) sites across south east England and East Anglia. We offer Local Authorities and waste contractors the opportunity to:

  • reduce biodegradable municipal waste (BMW) inputs to landfill (and to avoid the associated rises in landfill taxes) and incineration
  • deliver the stringent recycling targets set by the Government and the EU
  • offer a sustainable, low carbon, green waste management solution.

The resulting nutrient-rich, peat-free soil improver is a valuable source of nutrients for plants and crops. It allows farmers, landowners and landscaping companies to displace manufactured or peat based compost, and the peace of mind of using a locally produced, environmentally friendly, additive free soil improver.

How to buy our premium grade compost

In-Vessel Composting (IVC)

The in-vessel composting (IVC) process mixes organic material, including food waste, under strictly-controlled environmental conditions within a sealed and fully enclosed purpose-built bunker. The process meets the highest industry standards and is compliant with latest regulations as well as having a Category 3 Animal By-Products Regulations (ABPR) License.

We can process a range of organic material, including:

  • Kerbside domestic collected organics
  • Catering waste, including meat and fish
  • Local Authority civic amenity site garden waste
  • Commercial fruit and vegetables
  • Liquid food waste

After treatment, the compost is extracted from the IVC bunkers to bays where it’s left to mature for around 6-8 weeks. The product is a stabilised, nutrient-rich and peat-free compost which is suitable as a soil improver for the farming and agriculture industry. 

Open Windrow Composting (OWC)

Open windrow composting (OWC) processes garden waste only – grass cuttings, pruning and leaves – in an open environment and allows the material to break down in the presence of oxygen. Without exception, there is no food waste or animal by-products.  

There are multiple uses for the exceptional quality compost produced which, dependent on grade, can be used as a soil improver, mulch, topsoil constituent, turf dressing and as a growing medium. It can be used on domestic and commercial gardens, brownfield sites, for landscaping as well as full-scale agriculture.
