- The paper proposes a novel two-stage anaerobic digestion (AD) of grass, which is demonstrated with increasing energy yields by 13.4% in 12 days instead of 20. Using 25% of available UK grassland this would result in an additional 17.9 billion MJ of energy p.a. over a conventional single-stage AD system. The work resulted in an EU Co-Fund PhD with Welsh Water (£70k) and an international Rutherford collaboration with RMIT (Australia to further develop and implement the work at scale (contact Dave Holthofer). Our work has now been repeated and tested in at least 12 other published international studies
