About PureHemp Technology LLC


Hemp Refining Platform

PureHemp has secured global technology licensing rights to convert industrial hemp into hemp-based products. PureVision Technology, Inc. (“PureVision”) based in Ft. Lupton, Colorado, has developed and patented biorefining technologies to rapidly convert non-food biomass such as corn stover, wheat straw, grasses, wood and hemp into biobased products. PureHemp has demonstrated the unique capabilities of its refining technology that deconstructs hemp into its fundamental components that then become intermediate materials including:
  • Pulp, which is one of the products exiting the continuous countercurrent reactor (CCR), is made primarily from the cellulose fraction of the hemp stalks. The cellulose fraction makes up about 40% of hemp stalks. Pulp is used for making a wide variety of products including paper products, alpha cellulose, dissolving pulps, composites and building products. PureHemp is currently producing hemp pulp for paper, packaging products and producing 100%-derived hemp glucose sugar.
  • Lignin, which makes up about 20% of hemp stalks, is the “glue” that protects the cellulose and hemicellulose fibers. PureHemp is able to fractionate lignin from hemp stalks, which can then be used as a raw material to make many products, including chemicals and plastics.
  • Sugars from the cellulose and hemicellulose fractions of hemp, primarily xylose and glucose, can be used to produce products including sweeteners, beverages, chemicals and plastics.
  • Oils can be produced from two sources from the hemp plant. At a PureHemp refinery, hemp seeds and flowers will be converted into hemp oils, including full spectrum cannabinoid oil, which includes cannabidiol or CBD, now being used by health and wellness practitioners. PureHemp is currently converting hemp flowers into cannabinoid-rich oil.

Working with Farmers

PureHemp is and will continue to work with farmers and farming communities. With dwindling water supplies and continuing draught throughout much of the world, traditional irrigation practices are now changing in many areas. The versatile hemp plant offers an alternative to fertilizer- and pesticide-dependent crops with high water demands. Hemp refineries will pay farmers to cultivate hemp to sell to the PureHemp refinery.

Promoting Industrial Hemp

PureHemp is on the ground floor of a new hemp refining industry. PureHemp plans to benefit from this new opportunity not only by becoming an important link in the emerging value chain from farmer to consumers, but also by licensing technology packages to project developers and entrepreneurs.

Building PureHemp Biorefineries

PureHemp's mandate is to work with partners interested in developing refineries that convert hemp into intermediate and final products. PureHemp is planning to develop its first commercial hemp refinery in Colorado. Once proven out, plans are in place to develop hemp refineries throughout the world.
