Can plastics be removed from the environment and be biologically degraded? Chemical engineers at TU Wien (Vienna) are working on it
Scientists at the Institute for Chemical, Environmental and Biological Engineering (ICEBE) at TU Wien (Vienna) are trying to replace exploitation of the environment, by using ecologically balanced approaches. “There is no contradiction between technology and nature – quite the contrary”, says Anton Friedl, the director of the institute. “Nature can teach us about new technological approaches, and new technologies will benefit the environment. It is a process we call ‘imagineering nature”, he adds.
End market diversity is the blessing for manufacturers of extruders.
Extruders are used to make pipe and siding in the construction market, sheet and blown film in packaging and tubing for medical. Not to mention custom extrusion for everything from aerospace to writing instruments.
One slow market segment can be offset by another hot one, machinery officials said.
In construction, single-family housing starts were up 8 percent year to date through October, from the same period a year ago, on pace to hit an annual rate of 877,000 in 2017, according to the U.S. Census Bureau. Starts are beginning to get a boost from reconstruction activity from Hurricanes Harvey and Irma.
Mexico City — The increasingly sharp rhetoric over the future of the North American Free Trade Agreement wasn’t exactly center stage at Plastimagen. Visitors and exhibitors said the focus was definitely on business.
But still, like the hum of the machinery running in the exhibition halls, it was constantly in the background and could not be avoided.
Adding bits of irradiated plastic water bottles could cut cement industry’s carbon emissions.
MIT undergraduate students have found that, by exposing plastic flakes to small, harmless doses of gamma radiation, then pulverizing the flakes into a fine powder, they can mix the plastic with cement paste to produce concrete that is up to 20 percent stronger than conventional concrete.
U.K. naturalist and broadcaster David Attenborough has warned of the dangers of plastic in the oceans after witnessing the damage it causes while filming a new wildlife series.
Attenborough said that during the recording of the BBC’s TV series “Blue Planet II” he saw countless examples of the negative effect of plastics, according to comments in the Guardian newspaper on Sunday.
FCC Approves Alphabet’s Project Loon for Hurricane-Devastated Puerto Rico
NEWS ANALYSIS: The Federal Communications Commission has approved a license to enable Alphabet’s X innovation lab to set up its Project Loon communications system to provide emergency cell service to hurricane-devastated Puerto Rico.
WASHINGTON — Industry has made more than 9.1 billion tons of plastic since 1950 and there’s enough left over to bury Manhattan under more than two miles of trash, according to a new cradle-to-grave global study.
CORVALLIS, Ore. – Engineers at Oregon State University have used “additive manufacturing” to create an improved type of glucose sensor for patients with Type 1 diabetes, part of a system that should work better, cost less and be more comfortable for the patient.
A key advance is use of electrohydrodynamic jet, or “e-jet” printing, to make the sensor. Conceptually, e-jet printing is a little like an inexpensive inkjet printer – but it creates much finer drop sizes and works with biological materials such as enzymes, instead of ink.
