Comparative Evaluation of Soda and Nitrate-Alkaline Pulping of Hemp, Flax, and Sisal Post-harvest Biomass. [PDF]

ChemistryOpen
The study compares hemp, flax, and sisal as nonwood raw materials for pulp production using soda and nitrate‐alkaline cooking. It evaluates chemical composition, cellulose crystallinity, yield, delignification, and paper strength. Sisal showed the highest tensile performance, while the choice of cooking method significantly influenced the quality and ...

Chemical Modification of Hemp Shives and their Characterization

Procedia Engineering, 2012
AbstractLightweight lignocellulosic composites are potentially contributing to sustainable development. However, lignocellulosic fillers are not always fully compatible with an inorganic matrix, which causes a variety of adverse outcomes such as the coherence and mechanical properties of composites.

Extraction of Lignin from Hemp Shives

Environment. Technology. Resources. Proceedings of the International Scientific and Practical Conference, 2015
Industrial hemp contains 65-80% shives of the stalk and are composed of libriform fibres who are high lignin content. Steam explosion (SE) auto-hydrolysis is a simple treatment of biomass (agricultural waste, logging residues, etc.) by saturated only steam without any additional reagents, usually at pressures 32 atmospheres.

Development of an Axial Fractionator for Hemp Shive Cleaning and Industrial Applications of Shives

Journal of Agricultural Science, 2012
Due to increasing shortage of raw materials, traditionally used for production of wood based panels and other composite materials, there is a growing call for the use of raw materials from agricultural production. Hemp shive, a by-product of hemp straw processing, is in eager demand due to its wood-like material properties.

NMR and MRI observation of water absorption/uptake in hemp shives used for hemp concrete [PDF]

Construction and Building Materials, 2016
Abstract Hemp concrete used as a construction material is known to provide excellent thermal insulation and hydric regulation, and prevents condensation. Initial water content in the hemp and water exchanges between hemp and binder play a major role in these processes. Here we study how hemp absorbs liquid water.
