hempI have been blogging about alternatives to plastic for almost two years and I have hardly ever mentioned hemp. It’s not because I haven’t looked into it as an alternative material. It’s partly because the body of information online is sullied with the unfocused ramblings of stoned slackers. It’s mostly because I sometimes publish unfocused ramblings and I don’t want my mom or anyone else to incorrectly assume that I am a stoned slacker.

Hemp was actually displaced by other natural fibers before plastics like nylon and polyester were invented. During the Industrial Revolution materials like wood pulp, cotton, jute and manila were found to be more suitable for large scale mechanized production of paper, textiles, rope and other products. Technological advances also meant that rope ceased to be as vital to commerce as it once was. When the US government used a tax law to prohibit hemp and marijuana in the 1930s, there was no strong lobby to oppose the move.

Hemp does have some unique attributes. It is fast growing and dense. This means that herbicides are not required for hemp production. The length and strength of its bast fibers are actually a significant stumbling block because they make it difficult or impossible to retrofit existing processing facilities. Canada has fostered a fledgling hemp industry since the 90s and the biggest problem has been the risk of oversupplying the market for the fiber. Basically, production is infinitely scalable while processing and market demand are not.

Hemp should be part of the solution to the plastic problem, but my opinion is that it won’t be anytime soon because of logistics and more obviously because it is illegal to grow it in the USA.

There are some good hemp products on the retail market including reusable shopping bags. The information on this organic hemp products website suggests that many hemp products are made in China where they are processed using toxic chemicals and manufactured using unfair labor practices.

Update: I went back to this topic this afternoon and found a few websites belonging to large technologically advanced hemp processors. They make some pretty interesting products including auto components. With all the recent concerns about plastic auto parts off-gassing into the interior of new cars, hemp might find a niche in this industry.
