Anaerobic Digestion of Hemp and Flax Straw and Shives and Rapeseed Straw by the Ruminal Microbiota [PDF]

, 2023
To mitigate greenhouse gas emissions and improve energy supply security, there is an increasing effort toward the use of non-fossil energy sources. Crop residues have a great potential to be exploited as biomass for biogas production.

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.

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.

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.

Biodeterioration of Sustainable Hemp Shive Biocomposite Based on Gypsum and Phosphogypsum

Journal of Natural Fibers, 2021
The present research investigated bio-based construction material based on hemp shives and gypsum. Low-density material was developed with densities of 200, 300, and 400 kg/m3. Simple yet robust production technology was used. For the first time, a binder for biocomposites obtained from phosphogypsum was used and properties were compared to commercial ...

Investigation of Durability Properties for Lightweight Structural Concrete with Hemp Shives Instead of Aggregate

Applied Sciences, 2023
The paper presents the results of testing the performance of lightweight structural concrete containing hemp shives as an aggregate. It has been analysed how the higher binder content and use of the Portland cement affect the thermal and microbiological ...
