Hemp Plastics

Is there anything this plant can't do? I was just browsing around online and found the following information from Paul Benhaim's hemphasis.net website. I have not found much information about hemp plastics so as an overview I am copying Paul's summary below. His hemphasis.net website is here: Hemphasis.net

Hemp Plastics & Biocomposites
Henry Ford used hemp-and-sisal cellulose plastic to build car doors and fenders in 1941. On video Henry Ford demonstrated that his hemp cars were more resistant to blows from a sledgehammer than steel-bodied cars were.

The basic building block of plastics is cellulose taken from petroleum, but toxic petrochemical compositions are not the only way to derive plastics.

Plastics can be derived from plant cellulose, and since hemp is the greatest cellulose producer on Earth (hemp hurds can be 85% cellulose), it only makes sense to make non-toxic, biodegradable plastic from hemp and other organics, instead of letting our dumps fill up with refuse.

A recent technological advance with biodegradable plastics made from cornstarch has led to a new material based on hemp. Hemp Plastics (Australia) have sourced partners who have been able to produce a new 100% biodegradable material made entirely from hemp and corn. This new material has unique strength and technical qualities which have yet to be seen before, and this new material can be injection or blow-molded into virtually any shape using existing moulds, including cosmetic containers, Frisbee golf discs, etc.
Hemp hurds may be processed into cellophane packing material, which was common until the 1930s, or they may be manufactured into a low-cost, compostable replacement for Styrofoam.

Zellform (Austrian) has created a hemp-plastic resin called Hempstone, for use in musical instruments, loudspeakers, and furniture. This material can be carved into any desired form.

Hemp can also be made into compressed door panel and dashboards. Carmakers such as Ford, GM, Chrysler, Saturn, BMW, Honda, and Mercedes are currently using hemp composite door panels, trunks, head liners, etc.

These composites are less expensive than dangerous fiberglass counterparts. Hemp fiberglass replacements would only cost 50 to 70 cents a pound. These hemp composites could replace carbon and glass fibers, which have environmental and weight problems, and run from 60 cents to 5 dollars a pound.

The reason why virtually all European car makers are switching to hemp based door panels, columns, seat backs, boot linings, floor consoles, instrument panels, and other external components is because the organic hemp based products are lighter, safer in accidents, recyclable, and more durable.

The possibilities are endless with hemp plastics and resins, and Biocomposites. Virtually any shape and purpose can be fulfilled by biocomposite plastics. Just think of the possibilities and realize that biodegradable non-toxic products are always the wisest choice for the future. Buy smart. Buy Hemp.
