An integrated approach for utilizing waste products of 2G bio-refineries to fractionate the lignin of high purity. The present invention also provides a method of recycling of two waste products (2-G ethanol residue as the substrate (LRBR) and fusel oil/synthetic fusel oil (SFO) as one of the solvent) of the biorefineries in a beneficial manner to fractionate the lignin of high purity. The present method of separating high purity lignin comprises fractioning extractive-free lignin rich residue with a solvent, wherein the solvent is a mixture of SFO/Fusel oil and Formic acid. An optimized ratio of waste fusel oil and formic acid gave more than >85% yields of high purity lignin.

An apparatus and method for extraction of oils from botanical material using high-pressure hydrocarbons such as propane, or butane, or mixtures thereof are described. A high-pressure propane or butane saturated liquid/vapor mixture formed by pressure reduction through a valve placed before an extraction column, thereby serving as an expansion port was employed. The apparatus is capable of both continuous liquid extraction or batch-style liquid operation through the use of a manifold valve, which directs the solvent liquid/vapor in the system to either a supply tank or an extraction column.

Electric jacket systems and methods for extraction are described. A system may be arranged or arrangeable for electrically controlling a temperature of one or more extraction system components. The system may include a first plurality of thermoelectric devices, the first plurality arranged or arrangeable for coupling with a first extraction system component at multiple locations along the first extraction system component. The system may further include a controller operably coupled to the first plurality of thermoelectric devices, with the controller configured or configurable to establish or maintain at least a first target temperature by selectively applying or causing the selective application of electrical power to the first plurality of thermoelectric devices.

A solvent extraction process for extracting oil containing dihomolinolenic acid from marine macro-algae, since as ascophyllum. Harvested ascophyllum is desalted to a salt content of less than 3% by weight, and dried to a moisture content of less than 5% by weight, and is then chopped into pieces of maximum dimension not exceeding 5 mm. The desalted, dried and chopped ascophyllum is then packed into a cellulose soxhlet thimble (13) and covered with a silica glass wool. The soxhlet thimble (13) is then placed in a vessel (12) of a soxhlet apparatus (11). A solvent reservoir (15) is charged with the solvent, namely, a food grade hexane, and is evaporated from the solvent reservoir (15) and condensed in a condenser (22) above the vessel (12) and is drip-fed into the soxhlet thimble (13) for extracting the oil containing the dihomolinolenic acid from the ascophyllum. The solvent with the extracted oil entrained therein is returned to the solvent reservoir (15) and the process continues until substantially all the oil has been extracted from the ascophyllum. The oil containing the dihomolinolenic acid is then recovered from the solvent by low pressure distillation until the solvent content of the oil containing the dihomolinolenic acid has been reduced to less than 5% by weight. The oil containing the dihomolinolenic acid is then desolvated to remove the remaining solvent therefrom.

The invention relates to a method of separation by fractionalization of the antioxidant active ingredients of Rosemary plant, which are the diterpenes Carnosic acid and Camosol and the phenolic acid Rosmarinic Acid, through column chromatography method. The production process involves the passage of rosemary extract, which is obtained in/with a proper solvent, through a column packed with a suitable packing material, the separation of the part rich in carnosic acid and carnosol, and the obtainment of a deodorized product in powder form after drying. During the process, another extract containing rosmarinic acid with high antioxidant activity is also obtained. The invention thus allows the use of an extract rich in carnosic acid and carnosol and another extract containing rosmarinic acid—which are obtained at once with no need for additional processes like acidification, precipitation, membrane filtration or deodorization—in food, pharmaceutical and cosmetic sector applications.

A composition for treating respiratory diseases and strengthening the immune system is provided including a synergic mixture of a) oil extracted from seeds of the plant Nigella sativa diluted in propylene glycol with b) an alcoholic extract with ethanol obtained from aerial parts of the plant Asclepias curassavica. The composition is prepared by (a) extracting seed oil from the Nigella sativa plant, adding the extracted seed oil to propylene glycol; (b) macerating aerial parts of Asclepias curassavica plants in ethanol with a resting time if subjected to a water bath or another resting time without the water bath, straining and filtering; c) mixing a volume of the alcoholic extract of Asclepias curassavica with a volume of oil extracted from the seeds of the Nigella sativa plant diluted in propylene glycol; d) shaking and letting it rest.

Disclosed are extraction solvents used in compositions and methods to refine synthetic feedstocks derived from plastic. Methods of refining plastic-derived synthetic feedstocks are also provided. For example, a method of refining a plastic-derived synthetic feedstock composition may include adding an extraction solvent to a synthetic feedstock composition derived from plastic pyrolyis to provide an extract phase and a raffinate phase, wherein the extraction solvent includes a polar organic extraction solvent immiscible in the synthetic feedstock. The methods may also include separating the raffinate phase from the extract phase to obtain a refined synthetic feedstock.

An arrangement of a mobile harvester decarboxylator with a terpene collector includes a heated enclosure for use in the field with terpene collectors coupled to ducted fume hoods of the heated enclosure. The terpene collector may include a chilled coil that condenses and separates oil-based terpenes from water-based terpenes via a centrifugal effect and/or immiscibility.

The invention relates to a process, method and devices for recovery of products from a feedstock such as an organic, non-organic or biodynamic feedstock. The products include consumables such as high nutrition foods, nutraceuticals and bioactive compounds and/or non-consumables such as energy and synfuels. The invention typically includes real-time process optimisation. The devices include a counter current diffusion extractor and a decorticator for deriving useful products from a feedstock, optionally for consumption in further processing.
