Rogers says the whole system is about as stiff as the plastic used to make food wrappers.

Complex components, plastics and other substances in TV products can create significant potential to contribute to high chemical and formaldehyde exposures, according to UL Environment.

The whey is used as a bio-coating a biodegradable film-for the plastic, offering additional protection while also being recyclable.

Additionally, the plastic based on whey is easily recyclable because the whey product can be ashedoff from the plastic layers by treating it with special enzymes('protease'and'alcalase),

This platform uses oll-to-roll manufacturingwhich is the process of creating electronic devices on a roll of plastic or foil.

and as a result, high-quality new plastics from old plastics will soon be a possibility.

e g. turning a used plastic bottle into a lower grade product, or rubber residues to floor coverings or safety crash pads.

The new plastic compounds are called elastomer powder modified thermoplastics or EPMT for short. They are made up of rubber residues crushed into elastomer powder that are blended with thermoplastics.

In recent years, dental correction orthodontics have used braces made from clear plastic polymer to good effect,

They may be made of metal, white porcelain or clear plastic. Braces made from a clear plastic polymer have a better aesthetics

when compared to metal braces, but they do come with their own set of problems, such as wear and tear within the mouth.

#Ultravisc#Separating the plastic from the chaff To the untrained eye, recycling almost appears to be like some kind of alchemy, that medieval art

Recycling plastics has many environmental and economic advantages. With dwindling global supplies of oil, recycling offers a powerful means of reducing the amount of petroleum (currently standing at around 8%of global production) required to manufacture plastics, the production

of which is growing steadily. In fact the amount of plastic produced in the first decade of this century is believed to have exceeded all that was produced in the previous one.

Plastic waste, which has a tendency to spread to even the remotest environments, can take centuries to decompose,

Although reducing the amount of disposable plastic products manufactured offers the most sustainable way forward,

The complex structure of plastic polymers makes the mixing of different plastics difficult or can result in weaker materials,

i e. the process of pushing the melted plastic through a special die which cuts or shapes it into the desired form,

The EU-funded project'Sensor-base ultrasonic viscosity control for the extrusion of recycled plastics'(Ultravisc) has broken the mould

"The ultrasonic technology is used to control the flow of the plastic through the production line and to control the properties of the plastics,

resulting in the production of a more consistent product,"explains Dr Paul Beaney, the technical manager at Cherry Plastics Group which coordinated the project."

"Ultrasonic technology had never been integrated into recycling technology before, so building the ultrasonic modulator was a big challenge,

and enables you to use more waste plastics in the process, thereby improving the environmental friendliness of the recycling process,

#Building new plastics with smart software Chemists can help create a wide range of plastics from polymers,

When chemists come up with a new idea for a plastic, it can sometimes involve a trial-and-error process of mixing elements in the laboratory.

In addition, because many of these materials are derived plastics from fossil fuels, they also increase the impact on climate change.

but instead of printing with plastics, it deploys edible ingredients squeezed out of stainless steel capsules:""It's the same technology,

"but with plastics there's just one melting point, whereas with food it's different temperatures, consistencies and textures.

#New recyclable plastics discovered by accident A collection of new plastics that are recyclable and adaptable have been developed by researchers

stiff plastics and flexible gels that can mend themselves if torn. The findings, reported in the journal Science, could lead to cheaper and greener cars, planes and electronics.

It is the first time that durablethermoset plastic has been produced in a recyclable form. Dr Jeanette Garcia, from IBM s Almaden Research center in San jose, stumbled upon the first new class of thermosets in many years when she accidentally left one of three components out of a reaction.

That chunk of plastic, produced from unexpectedly simple ingredients, proved to be tremendously hard and stable.

Yet until now, none of this thermoset plastic could be recycled. The potential impact here is said phenomenal

As well as very hard and durable plastics the researchers adapted their procedure to a different monomer and produced flexible, self-healing gels.

or treating the plastic with a chemical like acetone, which is used commonly to make desktop printed items smooth.

The Robox, for example, uses one extruder that prints a large volume of plastic, while a second extruder prints thin strands to add detail.

which would enable a piece of plastic to create the shape by self-folding. The second paper presents designs that show how to build electrical components (such as resistors, inductors, capacitors, sensors and actuators) with self-folding laser-cut materials.

#Self-healing plastic grows back after damage The newly-developed self-healing plastic can take rather extensive damage

A plastic developed by the University of Illinois is one of the latest plastics developed that regenerates when damaged.

The difference between this plastic and scratch-healing gadgets presently available is the amount of damage that can be tolerated.

Fullerenes turned out to be the type of additive that most effectively protects the insulation plastic.

"The researchers place the nanowires on the Shrinky Dinks plastic as they would for any other substrate,

"The plastic is clamped before baking so that it only shrinks in one direction, so that the wires pack together

The researchers also can control how densely the wires pack by varying the length of time the plastic is heated.

They also are exploring using lasers to precisely shrink the plastic in specific patterns. Nam first had the idea for using Shrinky Dinks plastic to assemble nanomaterials after seeing a microfluidics device that used channels made of shrinking plastic.

He realized that the high degree of shrinking and the low cost of plastic could have a huge impact on nanowire assembly and processing for applications."
