Most of the Western World banned the cultivation of Cannabis sativa in the early 20th century because biotypes high in ∆9-tetrahydrocannabinol (THC, the principal intoxicant cannabinoid) are the source of marijuana. Nevertheless, since 1990, dozens of countries have authorized the licensed growth and processing of “industrial hemp” (cultivars with quite low levels of THC). Canada has concentrat...

Biocomposites are being developed for structural applications, particularly in the automotive industry. The use of plant fibers as reinforcement is a first step toward development eco-materials, but it necessary to also more eco-friendly matrix. In this paper, woven hemp composites impregnated with two different eco-polymers compared: hemp/Greenpoxy and hemp/Elium. Greenpoxy partially bio-based...

field experiments were conducted to determine the optimum application rate of sunn hemp crotalaria juncea leaf residue in the management of meloidogyne incognita on tomato. sunn hemp applied at rates of 0 (control), 2, 4 and 6 kg/ha showed a varied effect on second stage juveniles of m. incognita. there were no differences in plant height and stem girth. the 6 kg/ha treatment reduced the m. inc...

This work used a literature search to select the most suitable system for delignification process of annual plants. was evaluated in terms lignin removal from plant biomass. Based on previous experiments, low transition temperature mixture (LTTM) used, which choline chloride and lactic acid molar ratio 1:2. Samples hemp fibers were examined. The biomass monitored by changing content main compon...

Non-wood biomass is particularly attractive as a cellulose source because of the lower lignin content. However, optimal extraction conditions are required content varies between plant sources. Further, use organic acids in place harsh mineral interest “greening” production process. This study sought to establish optimum parameters for microfibers (CMFs) from hemp (Cannabis sativa) biomass, usin...

The adsorption of two commonly used pesticides, diuron and tebuconazole, on an organic substrate (hemp), which was chosen as an analogue for natural substrates often found in agricultural ditches, has been studied using three different contact schemes: 1) contact in a beaker using a modified batch method; 2) contact in an experimental flume, with a dry start substrate; and 3) same as 2) but wit...

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 64(3): 803–812. Wheat fl our substitution by barley one led to shortening of fermentation and leavening times (about 14–57% and 35–83%, respectively) as well as to l...

The article is focused on analyzing the effect of functionalization and reactive processing on the morphological, thermal, rheological and mechanical properties of composites of isotactic polypropylene (PP), polystyrene (PS), poly(ethylene-vinyl acetate) (EVA), with cellulose fibers, hemp or oat as natural fillers. Both polymers and fibers were modified with bi-functional monomers (glycidyl met...
