Introducing BioCup 4oz BioCup Single Wall (50 in a sleeve), the new eco-friendly coffee cup. Your coffee cups are now produced in an environmentally responsible way. Unlike traditional paper cups that use a petroleum based plastic lining, the BioCup uses a compostable corn-based plastic lining. Therefore, it is fully renewable, EN13432 certified compostable, and leaves a smaller environmental footprint. And it does so without adding anything that will distract from the rich, deep flavour you have come to know and love. One more step towards a sustainable future. Together, we can make a difference one coffee at a time.
