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?
Just in time for Earth Day, chemicals leader Bayer MaterialScience reported from the UTECH Europe 2015 polyurethane show on programs and applications using its materials to help reduce energy usage. The company also gave an update on its CO2-based PU as that eco-friendly material comes closer to production.
A slew of announcements about new materials and design concepts for transportation have come out of several trade shows focusing on plastics, aircraft interiors, heavy trucks, and automotive engineering. A few more announcements have come independent of any trade shows, maybe just because it's spring.
At the JEC Europe 2015 composites show in Paris last month, makers of composite materials, software, and process equipment showed off their latest innovations. This year's show saw some announcements related to automotive applications, but many of the improvements came in the world of aerospace.
The DuPont-sponsored Plastics Industry Trends survey shows engineers want improved performance in a broad range of plastics and better recycling technology. These concerns top even processing enhancements that improve productivity.
Plastics leader SABIC recently announced a global initiative to help its customers take advantage of additive manufacturing (AM) and also advance 3D printing (3DP) technologies in several application areas. The company's plans go way beyond materials, and also include design, processing, and part performance.
