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 table below.
