A study by two business school professors makes the case that green manufacturing is not an expense; in fact it’s a money-maker. It took 20 years, but a Subaru plant in Indiana that makes 800 cars a day has reduced by waste 47 percent and makes use of 99.9 percent of the remaining waste. Nothing goes to a landfill, and dumpsters have been converted to recycling bins. One of the biggest problems was a toxic solvent used to flush painting systems. Subaru now distills impurities from used solvent so that it can be re-used. The impurities go to a company that makes coatings for steel industry ladles. There are a thousand examples, but one of the more intriguing (odder?) is to use all cafeteria food waste in a circular composting track. One day’s waste would be placed next to the last day’s in a plan under study. Special worms devour the waste, leaving rich soil behind. Or, I guess, Subaru could just hire workers who clear their plates.
United Launch Alliance will fly 3D-printed flight hardeware parts on its rockets starting next year with the Atlas V. The company's Vulcan next-gen launch vehicle will have more than 100 production parts made with 3D printing. The main driver? Parts consolidation and 57% lower production costs.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
Although bio-based polymers face challenges from petroleum-based polymers, in certain markets they can displace the petro-based incumbents. Here are six new bio-based and renewable plastics for a variety of applications.
BASF has developed tools and initiatives to help engineers use more of its renewable materials in their designs, more effectively, as well as to build parts using them with more predictable performance.
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.
