A Massachusetts-based company is genetically modifying switchgrass to produce a polymer used to make plastics.
The greenhouse at Metabolix’s lab is full of grass. That would be unexciting, except that the 300 or so pots of switchgrass growing here have been genetically engineered to produce a kind of polymer used to make plastics.
Metabolix, a bioplastics company founded in 1992, is one of a small group of companies and universities pushing at a new frontier in bioplastics: the genetic engineering of crops to produce plastics materials. The efforts – unique in making bioplastics not from, but in, crops – put forward a solution to the longstanding problem in bioplastics: how to make the production costs of bioplastics as cheap as, or cheaper than, oil-based plastics.
The answer, these scientists say, is in plants: What if crops, planted in droves in US farm fields, could become quiet, tiny plastics factories, churning out all the plastics we need?
But that, of course, raises another question: Is that even possible?
Bioplastics, simply put, are plastics made from renewable biomass resources as opposed to fossil fuels. Billed as a potentially cheaper and more sustainable alternative to conventional oil-produced plastics, bioplastics is a fledgling industry, and, so far, both eco-friendliness and cheapness have not been achieved in one product.
