Investors are putting a lot of money into bioplastic ventures. But the jury is still out on their environmental benefit They were panned in a recent study conducted by the University of Pittsburgh Now comes an announcement from Unilever that bioplastics won’t be part of an aggressive sustainability program in packagingUnilever makes this comment:
“Bioplastics are derived from renewable resources. But this does not mean that they are sustainable when all the environmental impacts and issues around their growth, production and subsequent disposal are taken into consideration.”
That’s a pretty broad-brush statement considering all of the technologies being investigated for renewably sourced packaging materials Unilever’s overall dismissal of this technology may be unwarranted But who really knows for sure? The companies with a stake in the plants-to-plastics projects need to make more convincing cases of their environmental benefits
Last week, the bill for reforming chemical regulation, the TSCA Modernization Act of 2015, passed the House. If it or a similar bill becomes law, the effects on cost and availability of adhesives and plastics incorporating these substances are not yet clear.
The latest crop of coating and sealant materials and devices has impressive credentials. Many are designed for tough environments with broad operating temperature ranges, and they often cure faster, require fewer process steps, and produce less waste.
A new program has been proposed for testing and certify 3D printing filaments for emissions safety. To engineers who've used 3D printers at home this is a no-brainer. It's from a consumer on Kickstarter, and targets use in homes and schools.
For the last 50 years, the Metal Powder Industries Federation (MPIF) has sponsored an awards competition for creative solutions to designing and fabricating near-net-shape parts using powder metal (PM) technologies. Here are the seven Grand Prize winners of the 2015 contest.
Graphene 3D Lab has added graphene to 3DP PLA filament to strengthen the material and add conductivity to prints made with it. The material can be used to 3D print conductive traces embedded in 3D-printed parts for electronics, as well as capacitive touch sensors.
