“…The process of deconstruction of lignocellulosic plant material, including bioextrusion, has been developed using one or two consecutive extruders at the laboratory scale (Vandenbossche et al, 2014b). Industrialization of the process requires adapting the twin-screw extrusion technology to integrate all process operations into a single step twin-screw extrusion device at a higher scale.…”

“…Three piston pumps (DKM Super K Camp 112/12, DKM Super MD-PP-63 and DKM K202 P32) were used to inject, respectively, an alkaline solution of sodium hydroxide (NaOH), an acid solution of phosphoric acid (H 3 PO 4 ) and an enzymatic solution. The operating conditions were based on conditions previously developed for a process using two extruders (Vandenbossche et al, 2014b) and adapted to a single extruder (Tables 2 and 3).…”

“…This biomass is mostly used for forage for ruminant animals and has been little studied for energy production. Its use as a source of sugar for energy production has been tested in previous studies using alkaline pretreatment followed by bio-catalytic hydrolysis in a twin screw extruder (Vandenbossche et al, 2014b(Vandenbossche et al, , 2015.…”

“…Karunanithy and Muthukumarappan (2013) provide an overview of the combination of extrusion with alkaline pretreatment, including the factors that influence extruder and feedstock parameters and an evaluation of the pretreatment efficiency. A continuous process combining alkaline thermomechano-chemical pretreatment, followed by the injection of enzymes into the twin-screw extruder, called ''bioextrusion" was developed and tested on different biomass sources such as sweet corn residue (SC), blue agave bagasse, OPEFB as a residue from palm oil manufacture, and barley straw (Vandenbossche et al, 2014b). This new process results in excellent mixing of the enzymes with the pretreated biomass at high concentrations, and allows saccharification to begin during bioextrusion (Vandenbossche et al, 2015).…”

Combination of alkali pretreatment and biocatalytic action in extruder. Validated of the process on six different lignocellulosic biomasses. Keywords:Lignocellulosic biomass Twin-screw extruder Alkaline pre-treatment Enzymatic hydrolysis Bioextrusion a b s t r a c t A process has been validated for the deconstruction of lignocellulose on a pilot scale installation using six types of biomass selected for their sustainability, accessibility, worldwide availability, and differences of chemical composition and physical structure. The process combines thermo-mechano-chemical and bio-catalytic action in a single twin-screw extruder. Three treatment phases were sequentially performed: an alkaline pretreatment, a neutralization step coupled with an extraction-separation phase and a bioextrusion treatment. Alkaline pretreatment destructured the wall polymers after just a few minutes and allowed the initial extraction of 18-54% of the hemicelluloses and 9-41% of the lignin. The bioextrusion step induced the start of enzymatic hydrolysis and increased the proportion of soluble organic matter. Extension of saccharification for 24 h at high consistency (20%) and without the addition of new enzyme resulted in the production of 39-84% of the potential glucose.

Abstract.Reactive extrusion is a cost-effective and environmentally-friendly method to produce new materials with enhanced performance properties. At present, reactive extrusion allows in-situ polymerization, modification/functionalization of polymers or chemical bonding of two (or more) immiscible phases, which can be carried out on commonly used extrusion lines. Although reactive extrusion has been known for many years, its application for processing of bio-based polymer blends and composites is a relatively new direction of scientific research. This work presents a literature review on recent advances in the processing of bio-based polymer blends and composites via reactive extrusion. We described compatibilization mechanisms for different types of biodegradable polymeric materials based on: (i) aliphatic polyesters, (ii) aliphatic polyesters/starch and (iii) aliphatic polyester/natural rubber systems. A special attention was focused on conventional and dynamic cross-linking of bio-based polymer blends and composites as an effective way to prepare new materials with unique properties e.g. biodegradable thermoplastic elastomers or shape-memory materials. Advantages and limitations affecting future trends in development of biodegradable polymer blends and composites reactive extrusion are also discussed.

In recent years, Agave has shown its potential as a bioenergy feedstock with a higher land productivity (up to 42 ton/ha year) than traditional feedstocks. Other features are its adaptation mechanism to high temperatures and its resistance to drought. The agronomics of Agave in Mexico are discussed, including total land planted, inputs required, and the harvesting and transport costs. Heating values, mineral concentration, and carbohydrate and lignin content show the potential of the Agave species to compete with current bioenergy crops. Currently, the pre-treatment of Agave is the most widely studied stage in biofuels and value-added products, which include technologies capable of reducing its recalcitrance while removing xylan and/or lignin and reducing cellulose crystallinity, among other effects, to increase the overall yield in saccharifi cation and fermentation, which will be discussed as well. In addition to spirits and fi bers from industrial interests, different liquid (ethanol and n-butanol) and gaseous (methane and hydrogen) biofuels, including certain value-added products (enzymes, lactic acid, and succinic acid), can be obtained from Agave in high yields. The main objective of this review is to address the recent advances in the utilization of Agave as a bioenergy feedstock for biofuels and value-added products within a sustainable biorefi nery scheme.
