Combine

The Combine project investigated the feasibility of turning waste plant material, such as rushes, gorse, bracken, grasses and roadside verge arisings, into fuel briquettes of a quality similar to woodchip.

Did you know previously unused biomass can be converted to energy? Roadside verges can be transformed into inter-connected biodiversity corridors.

The Combine project ran from December 2011 to June 2015.  The RE-DIRECT project, which runs from Sep 2016 to Sep 2019 will build upon the learning gained from Combine.

Combine was working to:

  • reduce greenhouse gas emissions and reliance on fossil fuels
  • increase biodiversity on roadside verges, as well as in areas dominated by aggressive species, by fostering nature-friendly and nature-conserving harvesting techniques, hence contributing to nature and water protection
  • increase the efficiency of anaerobic digestion plants by utilisation of the waste heat
  • offer a financially viable solution to green waste disposal, including roadside verge arisings and leaf sweepings
  • produce a storable biofuel that can be efficiently burnt in modern two‐stage combustion boilers

Combine was a partnership of four European countries; Germany, Belgium, France and the UK; all working together to promote and implement a novel German biofuel technology. The National Trust, Severn Wye Energy Agency and Cwm Harry were the three UK partners.

Q. What didn't you expect to happen at the start?

During the project we identified several other projects looking at similar issues and offering slightly different solutions. It was really useful to work with all these projects and to share experiences and ideas.

Q. What do you enjoy most about this project?

We also benefitted hugely from working with our European partners and learning from their experiences. It was good to be part of such a strong partnership.
