ABSTRACT
Biorefineries are a practical way of achieving real developments in the industry for the production of energy and chemicals under an ideal dream of replacing today's oil with biomass. Beta renewables uses a lignocellulosic biomass technology called Proesa, which takes non-food-chain crops, or feedstocks, such as giant reed, or agricultural waste material, such as wood residues. One of the real goals of biorefineries was the proposal of using the biomass as integrally as possible through sustainable technologies and strategies. The main challenge should be an overall strategy for future design, analysis, and implementation of new biorefineries with a real sustainability and avoiding to copy the same evolution of risky and polemic oil refineries. Glycerol is a very well-known residue from the biodiesel industry. A techno-economic and environmental analysis for a biorefinery based on coffee cut-stems is presented by C. A. Garcia for Colombia as a case study.
