Driving Innovation in AD: Round 2

14th December 2016

The second phase of the Driving Innovation in Anaerobic Digestion (DIAD) programme launched in 2012. WRAP’s DIAD programme aims to improve the cost and optimise the efficiency of anaerobic digestion.

Funding aimed at:
Scaling technology – taking technologies at their current scale and adapting them to meet the demands of smaller (or larger) AD facilities.
Processing and enhancing digestate – technologies which reduce the cost of digestate management or increase the value of the digestate in economic terms.
Proof of market of AD technologies – technologies, solutions and methods which are at the end of the research and development (R&D) stage



To find information on the feasibility studies and full-scale demonstration projects is available in the chapters. Check back regularly for updates.
