“…Lignin degrades upon exposure to UV-light and hemicelluloses degrade upon moisture absorption and biological means [12]. The UV-degradation process is known to be triggered by the formation of free radicals and probably starts with the oxidation of phenolic -hydroxyls [13].…”

Abstract. In this study, 30 wt% aligned untreated long hemp fibre/PLA (AUL) and aligned alkali treated long hemp fibre/PLA (AAL) composites were produced by film stacking and subjected to accelerated ageing environment. Accelerated ageing was carried out with an accelerated ageing chamber using UV-irradiation and water spray at 50 °C for four different time intervals (250, 500, 750 and 1000 hrs). After accelerated ageing, tensile strength (TS), flexural strength, Young's modulus (YM), flexural modulus and mode I fracture toughness (K Ic ) were found to decrease and impact strength (IS) was found to increase for both AUL and AAL composites. AUL composites had greatest overall reduction in mechanical properties than that for AAL composites upon exposure to accelerated ageing environment. FTIR analysis and crystallinity contents of the accelerated aged composites support the results of the deterioration of mechanical properties upon exposure to accelerated ageing environment.

“…Addition of lignin to the fibre pulp may however lead to bubble formation during high temperature pressing (Velazquez et al 2003). In another study, water stability (thickness swelling and water absorption), internal bond, and mechanical properties were reported to be improved in panel boards made from fibres of softwood residues defibrated in presence of extra lignin (Anglès et al 2001).…”

“…Van Dam et al (2004) report that lignin exhibits thermosetting properties at working temperatures of >140°C and acts as intrinsic resin in binderless board production. Lignin is the component that permits adhesion in the wood structure and acts as a rigidifying and bulking agent (Anglès et al 2001). Lehtikangas (1999) states that moisture of about 8-15% in biomass will reduce the softening temperature of lignin to 100-135°C by plasticizing molecule chains.…”

It is generally acknowledged that burning fossil fuels and deforestation are major contributors to anthropogenic climate change. Biomass from plants can serve as an alternative renewable and carbon-neutral raw material for the production of energy. Low densities of 80-150 kg/m 3 for herbaceous and 150-200 kg/m 3 for woody biomass limit their application in energy production. Prior to cost-effective use in energy applications, these materials need to be densified to increase their bulk densities to help reduce technical limitations associated with storage, loading, and transportation. Pelleting, briquetting, or extrusion processing are methods commonly used to achieve densification. The aim of the present report is a comprehensive review of biomass processing, which includes densification technologies and specific energy consumption, biomass pretreatment methods, densification process modeling, and optimization. The specific objectives include:
