Earth Stool is a circular bar stool designed by Danish architect Eva Harlou. Earth Stool is the result of a new innovative waste-to-value technique that enables Mater to reuse companies' industrial waste, e.g. plastic waste and other fibre-based materials. The seats are made from insulin pens in collaboration with Novo Nordisk and coffee bean shells from BKI coffee or waste from Carlsberg's beer production – the spent grain – mixed with post-industrial plastic waste. The technique is developed in collaboration with Danish Technological Institute with support from the University of Copenhagen. The waste materials are mixed in a unique compound suitable for press moulding – a method designed to reuse companies' resources more efficiently. Earth Stool represents classic Scandinavian design with steel frames that make the bar stool elegant and timeless. The Earth Stool supports the UN Sustainable Development Goals: 'Life on Land' (SDG 15), 'Responsible consumption and production' (SDG 12) and 'Partnerships for the goals' (SDG 17).
