Transition to a circular economy is a must if we are to protect our planet, but also if we are to increase the competitiveness of European industry. This is a long-term process that will require numerous initiatives at European, national and regional level. Companies see the circular economy as an opportunity. "Going green" is beneficial not only for the environment, but also for businesses, providing real savings in terms of raw materials, water and energy. The participants of the conference entitled "Sustainable industry in the Context of Circular Economy" tried to identify major opportunities and challenges emerging from circular economy. This publication summarised the outcome of this discussion which took place on 13 September in Kosice, Slovakia.
