Research areas of interest
1. Ethanol production from hemp hurd
Hemp is at least four times richer in biomass/cellulose potential than its nearest rivals: cornstalks, sugarcane, kenaf, trees, etc. Hemp produces the most biomass of any crop, which is why it is the natural choice for an energy crop. Hemp converts the sun's energy into cellulose faster than any other plant, through photosynthesis. Hemp can produce 10 tons of biomass per acre every four months. The cellulose can be converted to fermentable glucose, which holds the greatest promise for production and feedstock, because it could produce 100 gallons/ton. Their high value fibre can be extracted as first step. Then the remaining core material (mostly hurd) can be converted to alcohol.
2. Hemp fibre composite for green brake linings
Brake linings are currently made from asbestos in phenolic resin. “Since asbestos was banned, no fibre has completely replaced it,” Aramids are now commonly employed, but also metallic and mineral fibres. But as the cost of aramid fibre is high, any alternative low-cost fibre that can perform some of the work of such an expensive material in composite structures would be significant. “Hemp goes some way to meeting requirements in respect of a stable coefficient of friction and resistance to friction heat. It has adequate compression and shear strength.
Cashew nut shell liquid (CNSL) a renewable phenolic source is the viscous, dark brown substance found in cashew nut shell. It is a sustainable and naturally occurring source of phenolic compounds that can be used to produce thermally stable phenolic resins suitable for use as green brake pads having hemp fibre as reinforcement.
3. Phyto-remediation by Hemp plant
Phyto-remediation is the direct use of green plants and their associated microorganisms to stabilize or reduce contamination in soils, sludges, sediments, surface water, or ground water. Hemp plant has been found to be effective in decontaminating soil from heavy metal contamination.
4. Cellophane and rayon
Cellophane and rayon are both classified as regenerated cellulose fibres, as they are structurally identical to cellulose. They are produced similarly: cellulose is dissolved in alkali solution and extruded through a slit into a bath of sulphuric acid to make cellophane film, or through a spinneret to make rayon fibre.
5. Nanocellulose
Cellulose can be used to make a vast range of plastics and related substances. Much of the difference in physical properties is attributable to the length of the polymer chains and the extent of crystallisation. Cellulose is extracted from hemp and other fibre crops in various ways. The raw pulp can be hydrolysed (separated into its component parts through addition of water) at 50-90°C; it can also be soaked in a weak acid solution to separate the crystalline sections from the amorphous sections, to produce nanocrystalline cellulose. It can be further subjected to heat and pressure to produce an intriguing form known as nanocellulose—a “pseudo-plastic” that appears gel-like and viscous in normal conditions, but becomes more liquid when shaken or subjected to stress. Nanocellulose has a range of potential applications, as a composite plastic reinforcing material, as a super-absorbent to clean up oil spills or make hygiene products, and even as a low-calorie stabiliser in food technology.
