CityLoops: shaping a circular urban future

A circular economy transcends national boundaries. As many production chains are international, sharing our knowledge of circular economy practices is crucial to achieving our climate goals. As a pioneer of sustainable solutions, Rijkswaterstaat recognises this international dimension as an integral part of its mission.

The CityLoops project gave us the opportunity to help small to medium-sized cities develop sustainable circular solutions. Our focus extended to helping emerging cities in their initial steps towards a circular economy, particularly emphasising the role of procurement in valorising a city's 2 main waste streams: construction and demolition waste, and organic waste.

Handbook for circular economy

A key outcome of the project was the creation of a handbook to inspire and guide procurement professionals, local and regional governments, policymakers and private entities on their journey towards a circular economy. The handbook provides practical tools and advice for implementing circular procurement practices and promoting sustainable projects.

The CityLoops project aligns with Rijkswaterstaat’s aim to improve our understanding of the circular economy and waste management in urban areas. It highlights the importance of integrating circular principles into construction, procurement and efficient bio-waste management. This approach not only reduces waste and conserves resources but also addresses carbon emissions and biodiversity loss.

Working together towards urban circularity

Beyond the environmental benefits, circularity is also an economic opportunity, reflecting Rijkswaterstaat’s belief in the economic benefits of sustainable practices. Collaboration is the key to achieving an urban circular economy. By adopting circular procurement practices and supporting sustainable waste management, cities can accelerate the transition to a circular economy and contribute to sustainable development goals.
