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
The company that brought you 3D-printed eyeglasses has launched both an improved clear polymer material for 3D printing optical components and a high-speed, precision, 3D-printing process for making small- and medium-sized batches in a few days.
We've found an amazing variety of robot hands & arms in medicine, space, and service robots, as well as R&D and assembly. Some are based on industrial designs modified for speed or dexterity, while others more closely emulate human movements, as well as human size and shape.
To give engineers a better idea of the range of resins and polymers available as alternatives to other materials, this Technology Roundup presents several articles on engineering plastics that can do the job.
The first photos made with a 3D-printed telescope are here and they're not as fuzzy as you might expect. A team from the University of Sheffield beat NASA to the goal. The photos of the Moon were made with a reflecting telescope that cost the research team £100 to make (about $161 US).
