Hemp plastics come from the hemp stalks. You can make plastic products from the cellulose in the hemp stalks. Since hemp is the most significant cellulose producer – up to 85% of the stalks are cellulose – it is an excellent resource for plastic production. Henry Ford developed his first fenders and doors from hemp and other plant-based materials. He knew how strong and easy it was to make car parts out of hemp, but with the 1937 marijuana tax act, then making marijuana illegal, Henry had to move from hemp to settle for his car parts. Hemp fibers are broken down and molded into whatever product you want. The best part is all you need is hemp and water to make hemp plastics.
