Biorefining, a promising alternative to petrochemistry. Because of the price increase of fossil resources, of their uncertain availability and because of environmental concerns, alternative solutions able to mitigate global warming, and reduce the consumption of fossil fuels and carbon dioxide emissions should be promoted. The replacement of petroleum with biomass as raw material for bioenergy (biofuels, power and heat) and chemical production is an interesting option and is the driving force for the development of biorefinery complexes that will have a critical role to play in our common future. A biorefinery is a facility that integrates biomass conversion processes and equipment to produce fuels, power, heat and chemicals from biomass. In biorefinery, almost all types of biomass feedstocks can be converted to different classes of biofuels and biochemicals through various processes that maximize economic and environmental benefits, while minimizing waste and pollution. Through the integration of green chemistry into biorefineries, and the use of low environmental impact technologies, future sustainable production chains of biofuels and high value chemicals from biomass can therefore be established. Currently, the green biorefinery, the whole-crop biorefinery, the oilseed biorefinery and the lignocellulosic feedstock biorefinery are favoured in research, development and industrial implementation, essentially through fully integrated biorefinery complexes.
