Plastic is a great material for many purposes. Lite-On Mobile has a wealth of experience in the field, enabling it to offer products that can justifiably be called high-class. Surfaces can be made look and feel totally different to what we are used to when holding a plastic object - ceramic, velvet, shiny, color-changing and, even to the eye of an expert, totally seamless products. Those are the kind of qualities that give plastic products a high-class look - they are exclusive and expensive looking, but still at an affordable price. And that doesn't go for just mobile phone covers, but for almost anything you can think of. Kimmo Turunen, Senior Manager from LOM Plastics Innovations explains that Lite-On Mobile has developed a fast and cost-efficient way to remove tooling split lines from the visual surfaces of plastic parts. * Split line removal is a technique by which the seams in plastic parts are polished away before painting. Plastic parts may sometimes have features like ...

On average we each consume 120 grams of plastic wrapping on Christmas gifts most of which is of a type which almost impossible to recycle. Now researchers at the University of Warwick have devised a new technique which could process 100% of Christmas and other household plastic instead of the tiny fraction that currently actually gets processed - typically only 12% of such waste is truly recycled often and the rest is often put into land fill or simply burnt as fuel. Some plastic still goes straight to land fill but householders currently spend a great deal of effort separating out the rest of their plastic waste believing it will be recycled yet typically only 12% of "Municipal Plastic Solid Waste" is truly recycled.. It is often simply too time consuming to separate out and clean the various types of plastic of their persistent labels or other problems, as that requires significant laborious human intervention. An additional problem is that often objects ...

TU Delft Researcher Jean-Paul Meijnen has 'trained' bacteria to convert all the main sugars in vegetable, fruit and garden waste efficiently into high-quality environmentally friendly products such as bioplastics. There is considerable interest in bioplastics nowadays. The technical problems associated with turning potato peel into sunglasses, or cane sugar into car bumpers, have already been solved. The current methods, however, are not very efficient: only a small percentage of the sugars can be converted into valuable products. By adapting the eating pattern of bacteria and subsequently training them, Meijnen has succeeded in converting sugars into processable materials, so that no bio-waste is wasted. Basis for bioplastics The favored raw materials for such processes are biological wastes left over from food production. Lignocellulose, the complex combination of lignin and cellulose present in the stalks and leaves of plants that gives them their rigidit...

In a pioneering step toward achieving industrial-scale green production, scientists from the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and collaborators at Dow AgroSciences report engineering a plant that produces industrially relevant levels of compounds that could potentially be used to make plastics.

"We've engineered a new metabolic pathway in plants for producing a kind of fatty acid that could be used as a source of precursors to chemical building blocks for making plastics such as polyethylene," said Brookhaven Biochemist John Shanklin, who led the research. "The raw materials for most precursors currently come from petroleum or coal-derived synthetic gas. Our new way of providing a feedstock sourced from fatty acids in plant seeds would be renewable and sustainable indefinitely. Additional technology to efficiently convert the plant fatty acids into chemical building blo...

Braskem S.A. and Toyota Tsusho Corporation (Toyota Tsusho) have concluded the joint study of life cycle analysis for polyethylene derived from Brazilian sugarcane (Green Polyethylene), and has found that the Green Polyethylene emits less greenhouse gas (GHG) when compared to petroleum-based polyethylene even if it is delivered to the other side of the earth. The University of Tokyo, Tokyo, Japan conducted the analysis under the collaborative study with the parties using the preliminary eco-efficiency study performed by Fundação Espaço Eco in Brazil (2007/2008), which shows that 1 kilogram of Green Polyethylene emits 1.35 kilograms* of CO 2 equivalents of GHG when it is produced in Brazil, shipped to Japan, used by consumer as container and packaging, and then incinerated. Meanwhile, traditional petroleum-based polyethylene emits 4.55 to 5.10 kilograms in its overall life cycle. As a result, the study demonstrates that 70 to 74 percent of GHG can be reduced with the s...

Professor Andre Geim, who along with his colleague Professor Kostya Novoselov won the 2010 Nobel Prize for graphene - the world's thinnest material, has now modified it to make fluorographene - a one-molecule-thick material chemically similar to Teflon. Fluorographene is fully-fluorinated graphene and is basically a two-dimensional version of Teflon, showing similar properties including chemical inertness and thermal stability. The results have been reported in the advanced online issue of the journal Small. The work is a large international effort and involved research groups from China, the Netherlands, Poland and Russia.
