BBSRC and BEIS (the Biotechnology and Biological Sciences Research Council and the Department for Business, Innovation and Skills) commissioned an evidence based review of the contribution of the bioeconomy to the UK and the prospects for growth and increased productivity in these sectors. E4tech analysed the sustainability of the UK bioeconomy in terms of both current and future feedstock availability, potential sustainability issues of feedstocks and barriers to their exploitation. We provided detailed and insightful analysis on the prospects and barriers to growth for the biofuels, bioenergy, bioplastics and bio-based chemicals industries in the UK. We also used our in-depth knowledge of the bioeconomy to assess the relative position of the UK compared to that of other countries, in particular in terms of government policies. The final report brought together all elements of the UK bioeconomy and provided the client with a comprehensive overview and in-depth understanding of the individual sectors and linkages between them. The report is available from the BBSRC website.
