Driving Innovation in AD: Round 1

13th December 2016

This initial round aimed to improve two specific areas of AD, namely:

• the optimisation of processing and product manufacture at all scales of AD; and

• the reduction of costs and complexity of small-scale AD.

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



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 table below.
