Production of ethanol from lignocellulosic feed-stocks is of growing interest worldwide in recent years. However, we are currently still facing significant technical challenges to make it economically feasible on an industrial scale. Genetically modified lignocellulosic biomass has provided a potential alternative to address such challenges. Some studies have shown that genetically modified lig...

Lignocellulosic plant biomass is recognized as an alternative resource for sustainable production of liquid fuels, chemicals, and polymeric materials through the biorefining concept. The sugar platform one promising approaches commercial conversion cellulose and/or hemicelluloses in into targeted products biologically chemically carbohydrate saccharification. However, efficient, from lignocellu...

In order to improve the bioconversion of lignocellulosic materials in an environmentally friendly manner, we choose to use the ultrasonic energy. Since enzymatic hydrolysis of cellulose represents a significant part of production costs, it is economically advantageous to develop a technique for reducing the cellulolitic enzyme loading. Thus, the sonication was employed in a two steps concept pr...

The wheat straw as abundant lignocellulosic resource was successfully undergone in a benzylation reaction and plasticized with different contents (2.5, 3, 5 and 7 wt. %) of glycerol and stearic acid.The effect of type and concentration of plasticizers on the mechanical, thermomechanical, morphological and water absorption properties of Benzylated Wheat Straw (BWS) was investigated ...

The present invention provides wood derivatives and composite materials prepared by first solvating a lignocellulosic material using an ionic liquid. The solvated lignocellulosic material can be derivatized to incorporate functional groups, particularly groups that facilitate later combination with polymer materials, including non-polymer polymers. The polymeric materials can be combined with t...

• 87 wt% of urban parks and gardens green waste were converted into lignocellulosic fillers. The branches-rich fraction displayed the best reinforcing properties. Depending on targeted mechanical performance, could be sorted by dry fractionation. Urban constitute a low-cost highly available lignocellulosic-rich resource, that is currently treated in composting or anaerobic digestion processes. ...

46 J-FOR Journal of Science & Technology for Forest Products and Processes: VOL.1, NO.1, 2011 The extraction of hemicelluloses from wood chips is crucial for producing value-added biomaterials in a forest biorefinery utilization. The low concentration of dissolved lignocellulosic materials dissolved in pre-hydrolysis liquor (PHL) presents a big challenge to the overall utilization processes. In...

Abstract Bioenergy is a critical part of renewable energy solution to today’s energy crisis that threatens world economic growth. Corn ethanol has been growing rapidly in the past few years. Policy-makers and researchers alike are becoming aware that corn ethanol has some serious drawbacks. It adversely impacts food prices and is harsh on soil fertility. Lignocellulosic ethanol on the other han...

Contrary to the case of the United States where a systematic management of the RD&D on lignocellulosic ethanol prevails, in Europe the research works remain fragmented despite the efforts made by the European Union and in few member states. In most of the European countries, sustainable lignocellulosic resources may not be widely available in the future for bioethanol production due to the poss...
