According to the Wuppertal Institute for Climate, Environment and Energy, the number of coffee-to-go packages is about 20 billion, with one tenth produced by the coffeehouse chain Starbucks alone. Not surprisingly, therefore, environmentalists are demanding sustainable solutions. The packaging industry has successfully adjusted to this trend, providing environmentally sound packaging solutions for use while travelling, covering every possible usage scenario.
Although a traditional paper cup is lightweight and can easily be transported, it has a special plastic coating for hot drinks and is therefore difficult to recycle. Coffee shops and petrol stations are trying to persuade customers to do without disposable cups by offering discount on reusable cups. Nevertheless, the majority of people still prefer paper because it is more convenient. Innovative alternatives must meet the needs of the consumer and the environment alike.
A year ago, in 2014, the Dutch group AkzoNoble invented a to-go cup with inside coating that dissolves together with the paper during recycling. The EvCote™ Water Barrier 3000 is made from vegetable oils and recycled PET bottles. So far the coating has only been used for cold drinks.
