“…51 As per the International Energy Agency, Bioenergy-Task 42, biorefining is the sustainable processing of biomass into a spectrum of marketable products and energy, however a biorefinery could even be restricted to a single process, typically sugar fermentation to ethanol. 52 There is abundant literature on biorefineries dedicated to biofuel production, but biorefineries focussing on bioproducts were also documented. 16,[53][54][55][56][57] Actually, biorefineries dedicated to the processing of starch, sucrose or vegetable oils to bioproducts have been in operation well before the biorefinery concept was coined.…”

This critical review provides a survey illustrated by recent references of different strategies to achieve a sustainable conversion of biomass to bioproducts. Because of the huge number of chemical products that can be potentially manufactured, a selection of starting materials and targeted chemicals has been done. Also, thermochemical conversion processes such as biomass pyrolysis or gasification as well as the synthesis of biofuels were not considered. The synthesis of chemicals by conversion of platform molecules obtained by depolymerisation and fermentation of biopolymers is presently the most widely envisioned approach. Successful catalytic conversion of these building blocks into intermediates, specialties and fine chemicals will be examined. However, the platform molecule value chain is in competition with well-optimised, cost-effective synthesis routes from fossil resources to produce chemicals that have already a market. The literature covering alternative value chains whereby biopolymers are converted in one or few steps to functional materials will be analysed. This approach which does not require the use of isolated, pure chemicals is well adapted to produce high tonnage products, such as paper additives, paints, resins, foams, surfactants, lubricants, and plasticisers. Another objective of the review was to examine critically the green character of conversion processes because using renewables as raw materials does not exempt from abiding by green chemistry principles (368 references).

“…LCM biorefineries, conceived as integrated chemical processes enabling the selective separation and the efficient utilization of the major feedstock components, have been considered as a key instrument to develop the so‐called bio‐based economy,2 and even as a new manufacture paradigm 3. In biorefineries, various LCM fractions are converted into a multitude of commercially usable products, including fuels, energy, chemicals, and materials 4,5…”

The aqueous fractionation of native lignocellulosic materials with hot, compressed water (also known as hydrothermal processing or autohydrolysis) has been proposed as a fractionation method for biorefineries, as it enables the simultaneous removal of water‐soluble extractives and the solubilization of hemicelluloses, yielding a solid phase enriched in lignin and cellulose. When the operation is carried out under favorable conditions, the liquid phase from autohydrolysis contains valuable products derived from hemicelluloses, including oligosaccharides that keep the major structural features of the polymer (including substitution by acetyl groups). Post‐hydrolysis of oligosaccharides in media catalyzed by acids or enzymes yields fermentable media containing hemicellulosic sugars; whereas harsh acid hydrolysis conditions result in the production of levulinic acid. Subsequent delignification of autohydrolyzed solids enables the separation of the three major lignocellulose components (hemicelluloses, cellulose, and lignin). As an alternative way for using autohydrolyzed solids, they can be used as substrates for the enzymatic hydrolysis of cellulose, leaving lignin as a solid by‐product. The sustainable manufacture of materials, fuels and chemicals from the biorefinery schemes cited above is discussed. Particular attention is paid to hemicellulose‐derived products. © 2011 Society of Chemical Industry and John Wiley & Sons Ltd

“…For example, LMW polymers and oligosaccharides can be hydrolyzed to sugars and acetic acid as fi nal products (Garrote et al 2001 ;Garrote and Paraj ó 2002 ). The sugars can be fermented to obtain fuels, chemicals, and materials (Saha 2003 ;Kamm et al 2009 ;G í rio et al 2010 ;Sanders et al 2010 ). Extractives or acid-soluble lignins may act as fermentation inhibitors.…”

The effects of hydrothermal treatments of Eucalyptus globulus wood have been evaluated in terms of the solid yield and the composition of the treated wood. The contents of cellulose, xylan, and Klason lignin in treated solids were determined and interpreted by means of kinetic models. Particular attention was paid to the degree of polymerization (DP) lowering of cellulose caused by hydrothermal treatments, which was assessed by measurements of intrinsic viscosity.
