Almost any product that can be made from wood, cotton, or petroleum (including plastics) can be made from hemp. There are more than 25,000 known uses for hemp.
For thousands of years virtually all good paints and varnishes were made with hemp seed oil and/or linseed oil.
Hemp stems are 80% hurds (pulp by-product after the hemp fiber is removed from the plant). Hemp hurds are 77% cellulose - a primary chemical feed stock (industrial raw material) used in the production of chemicals, plastics, and fibers. Depending on which U.S. agricultural report is correct, an acre of full grown hemp plants can sustainably provide from four to 50 or even 100 times the cellulose found in cornstalks, kenaf, or sugar cane (the planet's next highest annual cellulose plants).
One acre of hemp produces as much cellulose fiber pulp as 4.1 acres of trees, making hemp a perfect material to replace trees for pressed board, particle board, and concrete construction molds.
Heating and compressing plant fibers can create practical, inexpensive, fire-resistant construction materials with excellent thermal and sound-insulating qualities. These strong plant fiber construction materials could replace dry wall and wood paneling. William B. Conde of Conde's Redwood Lumber, Inc. near Eugene, Oregon, in conjunction with Washington State University (1991-1993), has demonstrated the superior strength, flexibility, and economy of hemp composite building materials compared to wood fiber, even as beams.
Isochanvre, a rediscovered French building material made from hemp hurds mixed with lime petrifies into a mineral state and lasts for many centuries. Archeologists have found a bridge in the south of France from the Merovingian period (500-751 A.D.), built with this process.
Hemp has been used throughout history for carpet backing. Hemp fiber has potential in the manufacture of strong, rot resistant carpeting - eliminating the poisonous fumes of burning synthetic materials in a house or commercial fire, along with allergic reactions associated with new synthetic carpeting.
Plastic plumbing pipe (PVC pipes) can be manufactured using renewable hemp cellulose as the chemical feed stocks, replacing non-renewable coal or petroleum based chemical feed stocks.
In 1941 Henry Ford built a plastic car made of fiber from hemp and wheat straw. Hemp plastic is biodegradable, synthetic plastic is not.
