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
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.
A theme that was reflected in several ways at NPE 2015 was the use of 3D printing to assist in, or improve on, injection molding, as well as improvements in 3D printing materials and processes that are making better functional prototypes and end-use parts.
