The whey is used as a bio-coating a biodegradable film-for the plastic, offering additional protection while also being recyclable.
Tests ran on the Oxygen Transmission Rate (OTR) of the packaging showed that a layer of whey improved the protection level 30-fold compared to conventional plastic films.
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.
Dr Holger Wack, scientist at UMSICHT, explains the production process:''In the first step, the rubber residues, that can be meter-long rubber pieces,
This is then conducted to the melt-mix process with thermoplastics and additives. Here we use, for example, polypropylene as a thermoplastic material.'

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

In particular, polysulfone is of interest in the biohealth field in the development of medical/surgical equipment:
#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,

In addition, because many of these materials are derived plastics from fossil fuels, they also increase the impact on climate change.
With the above in mind, a European research project has developed new environmentally friendly materials that can replace oil-based plastic films used in packaging for food
These materials can compete with plastic films and other flexible packaging in terms of performance and cost, but have a much lower environmental impact.

From there Schroers focused on producing BMGS in sheets. That form he reasoned is the most conducive to practical manufacturing applications. eveloping a fabrication method for BMG sheets has been extremely difficult
which can be carried out as easily as the process for blow-molding plastics. Seeing the commercial potential for his technique Schroers launched his own company Supercool Metals.

#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.

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.
For example, a PVC sheet sandwiched between two films of rigid polyester featuring slits of different sizes contracts
The PVC becomes deformed creating different angles where the edges of the polyester films press against each other.
#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.
The newly-developed self-healing plastic can take rather extensive damage and heal it through a process of regeneration,

"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.
