“…Similarly, trash (sugar cane tops and leaves) can be made available by introducing green harvesting methods . Bagasse, together with trash, can be valorized as a lignocellulosic feedstock for the production of biofuels, bioproducts and biochemicals in a biorefinery . The implementation of a profitable biorefinery annexed to an existing sugar mill may revitalize the rural economy by contributing to the sugar industry's economic sustainability…”

“…Multiproduct plant biorefineries have been investigated for the production of furfural, xylitol, medium‐density fiberboard (MDF), and electricity from sugarcane lignocelluloses, of which the production of xylose syrup and furfural combined with MDF was profitable, with reported internal rates of return (IRR) of 16% and 19%, respectively . Other examples include the co‐production of ethanol, lactic acid, furfural, butanol, methanol, and electricity from sugarcane bagasse and trash in various scenarios, of which ethanol and lactic acid co‐production was the most profitable, with a reported IRR of 25.4% .…”

This study investigates whether a biorefinery, annexed to an existing sugar mill and co‐producing succinic acid, polyhydroxybutyrate (PHB), and electricity from sugarcane bagasse and trash lignocelluloses, will be a viable investment opportunity for existing sugarcane mills. Four scenarios were simulated in Aspen Plus® and were included in the economic analysis. Scenario A involved the production of PHB and electricity; Scenario B the production of PHB, succinic acid, and electricity; Scenario C the production of succinic acid and electricity; and Scenario D involved the production of electricity only. The most favorable configuration was found for Scenario B where PHB was produced from 25% of the fermentable glucose stream, and succinic acid from the hemicellulose hydrolysate together with 75% of the glucose, resulting in an internal rate of return (IRR) of 24.1% with a net present value of US$477.2 million. Alternatively, Scenario D could be selected if low capital (130.1 million US$) and operational costs (US$13.2 million) are desired, although weak returns (IRR 10.3% and net present value of US$6.08 million) were observed for an electricity price of 0.08 US$ kWh−1. © 2019 Society of Chemical Industry and John Wiley & Sons, Ltd

“…Still, small‐scale plants could work for processes producing high added‐value materials. For instance, Clauser et al . formulated a biorefining process for the production of either xylose syrup, furfural or xylitol at small‐scale from sugarcane; determining that the option giving the best internal rate of return was the production of sugar syrup and furfural combined with fiber board production, on a15 000 t dry bagasse d −1 processing rate.…”

“…A recent interesting approach is the conjunction of integrated process design and small‐scale biorefining . Main advantages of this concept are lower transportation costs, local economy benefits and local re‐use of wastes and co‐products . Moreover, small‐scale production may be adapted faster and with more flexibility to changing circumstances as in the drop in oil prices since 2014…”

Biorefineries are considered as an integrative thinking that focuses on the possibility of obtaining as many added-value products as technically and economically feasible. However, in practice most biorefineries comprise only enzymatic or chemical pretreatment followed by biofuel generation. The drop in oil prices may menace the development of this young industry, as has happened before in history. This has become a fundamental reason for which the biofuel industry should not consider only biofuels production, but enzyme and non-fuel based chemicals as well. Hence, this work aims at overviewing the most important enzymes involved in biotechnological processes and to describe their role in biorefineries. Bioethanol, biogas and biodiesel biorefineries are overviewed, along with the integrated and industrial types. Finally separation and purification processes in biorefineries are discussed.

“…Brazil is currently in a transition from burning the whole cane for harvesting to unburned (green) harvest . Sugarcane bagasse and fibrous residues are typically composed of 39-43% cellulose, 21-23% lignin, 25-32% hemicelluloses, and minor amounts of organic extractives and ash (Oliveira et al, 2013;Clauser et al, 2016), which make them a proper carbon source for valorisation. * Fibrous residues refers to brown leaves and green tops.…”
