“…In spite of the utilitarian availability of lignin about lignocellulosic-polymer composites, there is much less information concerning the use of lignin as reinforcement in commodity polymer such as polypropylene (PP) and polyethylene (PE) [10][11][12]. The effects of adding lignin to polyolefin have been described as changing the surface properties, thermal resistance and biodegradability by acting only as a filler.…”

“…Lignin is utilized as a stabilizer for plastics and rubber. It is also used in the formulation of dispersants, surfactants, and adhesives or modifiers to improve the performance of the composite by blending it with other polymers (Pouteau et al 2004;Simionescu et al 1993;Stewart 2008;Stoica-Guzun et al 2011).…”

Membranes were prepared from alkaline lignin and poly(vinyl alcohol) (PVA) by a film casting method, and their properties were evaluated. These blend membranes can aptly be termed as green by nature as they are totally non-toxic and eco-friendly. The optimal mass ratio was determined based on the mechanical properties of membranes. The microstructure, mechanical properties, oxygen and carbon dioxide transmission, light transmittance, and thermal stability of the membranes were investigated. The blend membrane exhibited better thermal stability and barrier performance to oxygen and carbon dioxide than a PVA membrane due to the incorporation of alkaline lignin. Both tensile strength and elongation at break were increased with increasing mass fraction of alkaline lignin up to 15%, at which point the maximum of tensile strength and elongation at break were 43.65 MPa and 211.6%, respectively. The blockage of visible light at 600 nm was 62.36%, which was an improvement of 314.90% compared with the PVA membrane (13.36%). Based on this result, we suggest that the mechanical properties of blend membrane containing 15% alkaline lignin are excellent and better than PVA membrane (40.26 MPa, 179.37%). Thus, an alkaline lignin/PVA blend membrane was judged to be potentially suitable as an eco-friendly packing material.

“…All bioconversion platforms for ethanol production from lignocellulosic biomass produce a lignin-rich solid residue which can be combusted for on-site electricity production (Larsen, Petersen, Thirup, Li, Iversen, 2008). Lignin is a good applicant in chemical industries, can be incorporated in resins to substitute phenols or as a cross-linker in epoxyresins (Simionescu, Rusan, & Macoveanu, 1993). Lignin incorporation in polyolefin increases resistance to ultraviolet rays without major modification in mechanical properties (Gosselink et al, 2004).…”

Biomass, as a renewable resource, has the potential to decrease our dependence on fossil fuels, provide energy security and mitigate environmental problems. Shifting dependence from petroleum-based to renewable biomass-based resources is generally viewed as key to the sustainable development and effective management of greenhouse gas emissions. There has been an increasing research interest in the assessment of bio-sourced materials recovered from residual biomass and their conversion techniques. Biomass which is generally considered as less important due to its light weight, bulkiness and less economic value can be a valuable feedstock in biorefineries. Many countries of the world are now on the way to effectively utilizing the so called neglected energy source for achieving greater and cleaner energy efficiency by adopting biorefinery approach. This review paper hereby critically examine the idea of biorefineries as a strategy for sustainability by using different available biomass feedstocks, techniques for their multipurpose conversion into useful chemicals, fuel and materials, and the associated challenges on the basis of relevant researches.
