We live in an era where future exhaustion of fossil fuels and much needed commodities is an accepted reality. At the same time, waste management puts an ever-growing strain on our environment. Rather than perceiving waste as a burden, we should look into its wide variety of useful properties, such as building materials from which new and alternative products can be created. The Circular City is where we manage waste, commodities and energy in smarter and more efficient ways. What can we expect from a circular approach? Less pressure on our environment, new business models, innovative designs and new alliances and cooperation between different stakeholders.
