I commented yesterday on the ridiculous study commissioned by the American Christmas Tree Association that claims PVC Christmas trees are better for the environment than natural trees. A study earlier this year by a consulting firm in Canada makes the opposite conclusion. ”The results for this impact category are clear: the natural tree is better than the artificial tree considering an average life span of six years for the artificial tree. This conclusion holds true for resource depletion as well,” state researchers for Ellipsos of Montréal, Quebec. If someone kept an artificial tree for a very long time, “ideally over 20 years”, they could reduce the impacts of the artificial tree, says Ellipsos.
If you like to drive deep into the country to chop down your own tree, then you could be better off with a PVC tree, strictly from an environmental lifecycle analysis, says the study. I say, go into the country, have a great time with your kids, and chop down your own tree. Deposit the tree at a composting site when done. I didn’t do any research, but how is that worse than a PVC tree made in China?
Thanks to my colleague Don Loepp at Plastics News for citing my blog post, and pointing out the Ellipsos citation in one of the Plastics News comments.
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.
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.
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. So if you can't attend live, attend at your convenience.
