Whey Protein Transformed into Sustainable Food Packaging

Whey protein, a milk protein that is a byproduct of cheese production, is often used in protein bars and shakes, but scientists in Barcelona have discovered that it can also be made into a more sustainable plastic for food packaging.

The WheyLayer project was funded by the us prescription cialis European Commission to find an alternative to petroleum sources in food packaging.  Through this project, research company IRIS found that whey protein could replace synthetic petroleum-based polymers.  The whey protein plastic has similar oxygen-blocking properties to traditional food packaging, but it's cheaper to make and, even better, more easily recyclable.

Traditional plastic packaging is hard to recycle because the petroleum-based polymers are almost impossible to separate for individual recycling, but with the whey protein plastic, the whey can be removed with enzymes so that the remaining film can be recycled or reused in new packaging.

This process also keeps the 40 percent of whey protein discarded by European cheese factories out of buy viagra pill landfills.

That is so interesting. It really looking into every aspect of the product when designing it. A problem with new 'green' technologies is they have not looked at the entire life cycle of the product, from production, to shipping, packaging, and discarding. It would be interesting too, if this could to put in backyard composting systems instead of recycled.

We should not be diverting food of any kind to production of food packaging. Snail mucus could be genetically engineered for use as food packaging. I would rather snail mucus than whey.
they are NOT diverting food

Read closely
"This process also keeps the 40 percent of whey protein discarded by European cheese factories out of landfills."

So unless you pick you food up at the local dump, then they aren't diverting your food.

If anything this would drvie down the cost of cheese, since they could make money on something they have to pay to have removed now.

Want to drive down the cost of corn? Find a use for corn stacks that would pay farmers about $100 a pound for the stacks and corn proces would drop big time.

Whey is not usually thrown away (contrary to what the article says). Whey is used to make sports drinks, weight building supplements and immune system bolstering tonics.

From the article, I'd suggest that things like that use 60% of the whey, and the rest find no market, and so has to cheap cialis find be discarded. That would fit with the "40% of whey" that the article states.
