Enhancing copper and lead bioaccumulation in rapeseed by adding hemp shives as soil natural amendments

Journal of Environmental Engineering and Landscape Management, 2014
The current study reveals the results of a phytoremediation process applied to a multi metal contaminated soil, located in close proximity to an energy power plant. Phytoremediation process was studied using the rapeseed cultivation, both in the presence

Production of Particleboard Using Various Particle Size Hemp Shives as Filler. [PDF]

Materials (Basel), 2022
Research was performed into the use of hemp shive as a fast-growing and carbon-storing agricultural waste material in the production of particleboard for the construction industry. Hemp shives were acquired and prepared for board production with the use of milling and sieving to reach two target groups with 0.5 mm to 2 mm and 2 mm to 5.6 mm particle ...

Hemp Shives: A Sustainable Biosorbent for Water Purification by Dye Removal

Key Engineering Materials
This study evaluates the potential of hemp shives (HS) as candidate for two basic dyes removal, namely Azure B (AB) and Malachite Green (MG), from aqueous solutions. The biosorption tests were conducted in batch mode. The influence of experimental variables, including pH, dye concentration, adsorbent dosage, and contact time, was evaluated.

Effect of Hemp Shive Granulometry on the Thermal Conductivity of Hemp-Lime Composites. [PDF]

Materials (Basel)
This study investigates the effect of hemp shive granulometry on the thermal conductivity and microstructure of hemp–lime composites. Three distinct particle size fractions—fine, medium, and coarse—were characterized using high-resolution image analysis to determine geometric parameters such as Feret diameters, circularity, and elongation.

An Impact of Moisture on Thermal State of Flax and Hemp Shives Thermal Insulations. [PDF]

Materials (Basel)
Plant-based materials exhibit different moisture absorption properties than synthetic materials. In the case of synthetic fibrous insulation, the effect of moisture on thermal conductivity can be relatively easily determined based on the mass fraction of moisture in the material’s skeleton.

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).
