Driving Innovation in AD: Round 1

13th December 2016

WRAP’s Driving Innovation in Anaerobic Digestion (DIAD) programme commenced in 2011 as part of the Defra AD Strategy and Action Plan. The DIAD programme seeks to improve the cost and optimise the efficiency of anaerobic digestion. 

Funding aimed to improve
The optimisation of processing and product manufacture at all scales of AD
The reduction of costs and complexity of small-scale AD

Overview

Overview

To complete this programme of work, WRAP has been acting in partnership with the Small Business Research Initiative (SBRI) on both of the areas, as well as with the Royal Agricultural Society of England (RASE) on the small-scale AD projects.

Information on the feasibility studies and full-scale demonstration projects is available in the chapters below:
