THE PILOT SYSTEM

You'll find our pilot system overlooking the canal at Camley Street Natural Park, 12 Camley Street, N1C 4PW. Just seven minutes walk from Kings Cross in Central London, its easy to get to. The system includes the following:

  • 0.6m3 mill and pre-feed tank
  • 2m3 Methanogen digester
  • 1.5m3 gasholder
  • digestate separator and storage
  • Compressor and storage cylinders
  • Ecogen CHP with microgen Stirling engine

The biogas is currently being trialed using a Baxi Ecogen CHP unit to generate electricity and heat in partnership with Microgen, the manufacturers of the Stirling engine used in the Ecogen and several other CHP units.

In warmer months, it is used in our closed-loop café for cooking.

We have been using digestate is used on-site as a liquid fertiliser to support food-growing and algae trials. The more solid fibre fraction removed from the tanks is added to compost and beds as a soil conditioner. The food is then used by the café and waste from the café goes back to the digester – the organic circular economy in action!

The fertiliser is available to the public and food growing groups and individuals by arrangement. If you would like to try some out do get in touch as we are producing plenty! We can supply supply it for free.

If you would like to come for a have a guided tour and introduction to the project contact us to arrange a time. We normally ask for a sliding-scale donation to cover staff time but if you don’t have the budget for this, get in touch anyway!

The project’s carbon footprint is minimised by using a cargo bike for local food waste collection from local businesses within a 1 mile radius.
