THE NEED

On the one hand, the increasing amount of green consumers around the world as well as the need to comply with the related legislative pressure has led to market demand for environmentally friendly packaging materials that still meet the need of sensitive food as well as pharmaceutical and cosmetic products. .

On the other hand, whey, a cheese by product can be highly polluting if not properly handled due to its high organic content and 50% of the 50 million tons of whey produced annually in Europe is still unprocessed.

In such context, the WHEYLAYER project has received a lot of interest from the packaging industry and its end-users, as the whey protein-coating offers good oxygen barrier properties and can be removed enzymatically thus the resulting multilayer films presents a greatly improved recyclability.
