First let's define what a biorefinery is according to BIO:
BIO's spokesman Paul Winters quoted a recent study by the UK Industrial Biotechnology and Innovation Growth team that estimated the current global market for biorefinery-based chemicals at $164 billion. This is up from the $150 billion 2010 projection the consulting firm McKinsey and Company estimated in 2006.
"Bio-refinery" - a facility that integrates production of biofuels, energy and value-added chemicals or - or plastics from renewable sources of sugar - similar to the current petrochemical refinery, but with flexible feed stocks.
The UK study estimated demand for plant-based chemicals could generate sales of nearly $600 billion by 2025.
