GE Plastics has come up with a way to turn post-consumer plastic waste, chiefly PET bottles, into PBT-based polymers. Not simply a recycling effort, GE spent two years developing a manufacturing process that chemically upgrades the post-consumer waste, turning it into a feedstock suitable for making PBT-based polymers. GE claims the process saves both energy and reduces CO² emissions compared to traditional PBT manufacturing. The new eco-materials come in two versions: Valox iQ is a PBT-based polymer derived from 85 percent post-consumer waste. Xenoy iQ is an alloy of polycarbonate and PBT-based polymers, the latter also derived from 85 percent post-consumer waste. The materials don't trade-off properties in return for their environmental advantages. In fact, GE developed them initially for Japanese auto component makers, among them DENSO. Potential applications include demanding uses such as automotive connectors, lighting bezels, energy absorbers and body panels.

Engineers at Fuel Cell Energy have found a way to take advantage of a side reaction, unique to their carbonate fuel cell that has nothing to do with energy production, as a potential, cost-effective solution to capturing carbon from fossil fuel power plants.
To get to a trillion sensors in the IoT that we all look forward to, there are many challenges to commercialization that still remain, including interoperability, the lack of standards, and the issue of security, to name a few.
This is part one of an article discussing the University of Washington’s nationally ranked FSAE electric car (eCar) and combustible car (cCar). Stay tuned for part two, tomorrow, which will discuss the four unique PCBs used in both the eCar and cCars.
