I have blogged here in the past against the use of bioplastics as a solution to the solid waste problem. They don’t degrade in properly built landfills and they can foul recycling streams. I was at a meeting last Wednesday, however, where the biopolymer producers seem to be improving their case.
Stefan Facco of Novamont said that the European Commission ranks composting on an equal level with recycling as a way to reduce waste. The only strategies ranking higher are waste reduction and re-use. Novamont is targeting food-service applications such as fast-food restaurants and cafeterias where it’s too time-consuming or energy intensive to wash food waste off plates or utensils. Those materials would go into a composting stream instead of a recycling stream. The extent to which those types of composting systems will be developed, however, still remains to be seen. That’s the only case to me that may make sense for use of biodegradable plastics for food service products. Use of degradable plastic for agricultural mulch is a no-brainer and is already an important product. The cost of the starch-based bioplastics made by Novamont, however, still cost two to five times more than the commodity plastics they replace. Given that, might incineration of additive-free plastics in a waste-to-energy plant make more sense?
How can automakers, aerospace contractors, and other OEMs get new metal alloys that are stronger, harder, and can survive ever higher temperatures? One way is to redesign their crystalline structures at the nanoscale and microscale.
Although a lot of the excitement about 3D printing and additive manufacturing surrounds its ability to make end-products and functional prototypes, some often ignored applications are the big improvements that can come by using it for tooling, jigs, and fixtures.
A fun and informative tour you can attend at the upcoming Design & Manufacturing Minneapolis, MD&M Minneapolis, and other events there, is the Materials Innovation Tour on Wednesday afternoon. I'll be leading it.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies.
You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived.
