Vapothermal curing of hemp shives: Influence on some chemical and physical properties

Industrial Crops and Products, 2021
Abstract In a perspective of a sustainable development, a new generation of construction materials based on renewable plant resources has emerged to face environmental issues. However, the formulation of structural vegetal concretes (based on plant aggregates, a mineral binder and water) requires to enhance the compatibility of plant aggregates and ...

Evaluation of cellulose content in hemp shives after salt catalyzed hydrolysis

Energy Procedia, 2017
Abstract In recent years, substantial steps into the transition toward a bio-based economy have been taken. Therefore, biomass, due to its physical and chemical properties, has become one of the key sources to produce bio-based value products. From the current point of view, cellulose is the most common organic biopolymer and is considered as a ...

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 ...

MICRO- AND NANOPARTICLES FROM HEMP SHIVES AND HEMP CELLULOSE IN PAPERMAKING

Cellulose Chemistry and Technology, 2020
Nano- and microparticles were produced from hemp shives and hemp cellulose obtained thereof, using the thermocatalytic mechanical destruction method. The partially destructed material, at concentrations of 8-9%, was dispersed in water medium in a ball mill or ground without the presence of water in a ball mill (~15 h).
