Plastic bags, which retail chains once gave away for free in large quantities, pose a significant burden on the environment, as they can persist for up to hundreds of years. 
The European Commission even adopted a proposal last November that directly requires member states to limit the use of lightweight plastic shopping bags. Environment Commissioner Janez Potočnik stated:
"With this measure, we are trying to solve a very serious and obvious environmental problem. In Europe, more than 8 billion plastic bags end up as waste every year, causing enormous damage to the environment."
Scientists from the Faculty of Chemical and Food Technology at the Slovak University of Technology in Bratislava also tried to find a solution to this problem. They developed a new material for bags and films made from whey and starch. This special carbohydrate substance is more environmentally friendly, decomposes into biomass in compost, and leaves no heavy metals in the soil, which cooperates with our green decalogue. The success of the Slovak scientists is also demonstrated by the fact that their discovery was awarded a gold medal at the world exhibition in Taiwan.
