The PureHemp Biorefinery Technology

The PureVision Technology

PureHemp has exclusive worldwide access to a highly disruptive technology that has many advantages over current biomass conversion technologies. Based on years of R&D and favorable results, PureHemp’s patented continuous countercurrent reactor (“CCR”) technology along with other in-line equipment rapidly converts hemp stalks and other biomass into raw materials to manufacture a wide variety of products. Countercurrent processing, where the solid hemp stalks move in the opposite direction of the liquid reagent, has proven to cause highly effective reactions. Processing hemp in the CCR results in the production of pulp as one product, and the existing extract liquor is further refined into lignin and sugar co-products.


PureHemp’s CCR technology is very versatile, allowing different processing configurations for producing a wide variety of products.

1200 Pound per Day Pilot-Scale CCR: PureVision designed and built its first CCR in 2003, able to process 120 pounds (dry weight) of biomass per day. With a successful scale-up, the second CCR was developed in 2008, capable of processing 1200 pounds per day. In 2014, hemp was processed in the CCR for the first time. Based on encouraging results generated during the past 30 months, plans are underway to develop a small commercial-scale, 4-ton per day CCR, targeted to go into operation by July of 2017, followed by a 40-ton per day CCR planned to go into production in late 2018 or early 2019.

Employing the PureHemp CCR technology will add significant value to the emerging industry by utilizing the entire hemp plant for the economical production of hemp-based products. In addition to traditional products, there are novel products that can be produced from hemp using the PureHemp CCR technology, specifically pulp, lignin, sugars and extracts.

Hemp-based Products and Markets

The U.S. trend to legalize the cultivation of industrial hemp is a major driver for the PureHemp opportunity. There are many new business opportunities for farmers, end product manufacturers, entrepreneurs and investors. Perhaps the greatest emerging market driver is the demand for hemp-based products, ranging from nutraceuticals, body care products, food supplements, sweeteners, specialty chemicals, paper and tissues, plastics, lightweight composites, just to name a few. With the growing demand for hemp-based products in the U.S., the hemp value chain from field to end products coincides perfectly with the production, branding and marketing opportunities being developed by PureHemp.

Pulp from hemp can be used for a wide variety of end products such as sugars, specialty and packaging papers, bathroom and facial tissues, diapers, other personal hygiene products and building products. Unlike traditional pulping technologies that take hours to remove the lignin, the hemp pulp produced in the CCR takes, on average, 5 minutes.

Lignin is another raw material that PureHemp is able to efficiently extract from hemp. Unlike other technologies that produce lignin, the PureHemp lignin has been tested by third parties and shown to have outstanding and unique qualities, suitable for producing value-added industrial products including plastics, coatings and chemicals such as terephthalic acid and ionic liquids.

Sugars that will be produced from hemp refineries will primarily be glucose and xylose, both intermediate commodities used to make an array of beverages, nutraceuticals, chemicals, plastics and other consumer and industrial products.

CBD Oils have been produced and refined by PureHemp. Historically, extractions have been performed by PureHemp under contract with growers of high CBD strains of hemp. PureHemp employs ethanol as the solvent to perform cannabinoid extractions.

Hemp Seeds are typically separated from the plant when seeds are mature. Oil extracted from hemp seeds is a valuable component of the plant. Hemp oil and other seed-based products will be produced with off-the-shelf equipment.
