Treatment of spent cannabis biomass with activating agent
cannabis biomass is heated in stages, the first to remove water and volatile components, and the second to reclaim leftover cannabinoids. During a third, higher temperature stage, the biomass is converted to activated carbon.
Cannabis oil reacts with acetic anhydride with hexane and under reflux to produce THC-O-acetate and acetic acid using sulfuric acid as a catalyst. The resulting crude product is distilled and subjected to a SALLE with hexane followed by a SALLE with petroleum ether, before being distilled again in order to obtain a refined, THC-O-acetate product.
A process for producing THC-O-acetate using a succession of distillation, salting-out assisted liquid-liquid extractions (SALLEs), and solvent recovery techniques. Tetrahydrocannabinol (THC) in cannabis oil dissolved in hexane reacts with acetic anhydride under reflux to produce THC-O-acetate and acetic acid using sulfuric acid as a catalyst. The resulting crude product is subjected to a SALLE with hexane followed by a SALLE with petroleum ether, before being distilled in order to obtain a refined, THC-O-acetate product.

A slurry is made with ground cannabis biomass and a non-flammable co-solvent. The non-flammable co-solvent is made up of water and ethanol. The ultrasonication process extracts cannabinoids by applying ultrasound to the slurry. The slurry is then filtered, optionally centrifuged, and then distilled to obtain cannabinoid oil.

cannabis plant matter is agitated in a tumbler in a cooled environment to separate the trichomes from the remainder of the plant matter. The trichomes are then sieved using a sieve shaker with sieves of different mesh sizes mounted in a tower.

Hemp straw ash as a supplementary cementitious material
Hemp straw is ground and burnt to result in hemp straw ash for making concrete. The hemp straw ash is mixed with water, cement, fine aggregate, coarse aggregate and superplasticizer using a two-step addition process to form a concrete mixture.

Concentrated cannabis extract is obtained from raw cannabis plant material using a mixed solvent extraction process. The cannabis is soaked and agitated in a chilled mixture of butane, propane and isobutane. After removing the solid plant material, the remaining solvent mixture, now with dissolved extracts, is heated to remove the solvents. The remaining, viscous oil is then heated in a vacuum oven to purge the traces of solvent and result in a brittle shatter.

Refrigerated solvent is fed through a cooling jacket around an essential element extraction vessel. After circulating through the cooling jacket, the solvent is re-chilled and at least some of the solvent is passed into the extraction vessel, in which essential elements dissolve into the solvent.

Raw cannabis plant material is mixed with ethanol and spun-dry to extract cannabinoids. The ethanol may be chilled before adding it to the raw cannabis plant material, and a non-polar solvent stage may be used to increase the yield of the extraction. The resulting crude oil and ethanol with the dissolved cannabinoids is separated from the raw cannabis plant material and filtered to remove particulates, waxes, lipids, fats and dissolved impurities. The ethanol is then evaporated from the resulting mixture of oil and ethanol, and the remaining oil then undergoes brine- washing, decarboxylation and distillation to obtain the cannabinoids and other desirable volatile phytochemicals.
