Collaboration on resource recovery solutions for circular economy


On 15 December, Jaya Ratnam, Ambassador of Singapore, and Henk Snoeken, Deputy Director of International Affairs of the Ministry of Infrastructure and Water Management and thirteen partners signed a covenant, creating the PIB Cluster ReCirc Singapore. This covenant connects the partners in the exploration and realization of circular solutions in the field of sludge and waste processing and resource recovery solutions, both in Singapore and the Netherlands.

ReCirc Singapore is an initiative of Witteveen+Bos, Waternet, TU Delft and the Amsterdam Institute for Advanced Metropolitan Solutions. Director Stephan van der Biezen and CTO Arjen van Nieuwenhuijzen signed the covenant as coordinator and partner on behalf of Witteveen+Bos.

Aims of the covenant

This cooperation came about because the initiators, together with Singaporean partners, concluded last year that there are many similarities between Singapore and the Netherlands: both countries have limited natural resources, limited land space, are densely built, and are facing an ageing population which puts pressure on productivity. These similarities can be benefited by working together, exchanging knowledge and jointly exploring new markets and solutions. The Dutch embassy in Singapore has embraced this initiative, and together with RvO.nl, ReCirc Singapore has developed within the Partners for International Business (PIB) programme of the Dutch Ministry of Foreign Affairs.

About the consortium

The consortium starts with the PIB ReCirc program (2018-2020), creating the basis fora Centre of Excellence on Resource Recovery for Circular Economy (2021 and beyond). The cooperation within this covenant focuses on pragmatic solutions, more applied R&D, business development and cross sectorial collaboration. The following critical topics will be tackled:


  • Incinerated Bottom Ash and Fly Ash Treatment and Application as Building Material
  • Sorting, Separating, Segregating and Recycling of Urban Waste
  • Integrated Recovery of Renewable Energy and Resources from Waste, Used Water and UWTP Sludge
  • Packaging and Plastic Waste Management and Treatment
  • Food Waste Management, Treatment and Resource Recovery
  • E-waste Handling and Recovery of Valuable Materials


ReCirc Singapore is built as a Public-Private Partnership (PPP) of RvO.nl: a coalition between business, government, civil society organizations and knowledge institutions. It is an alliance of knowledge, know-how and business. In ReCirc Singapore the following companies and institutes are working together: Witteveen+Bos (cluster coordinator), Waternet, Amsterdam Institute for Advanced Metropolitan Solutions, Nijhuis Industries, Paques, CirTec, World of Walas, Asia Pacific Breweries, Organic Village, KWR Watercycle Research Institute, Delft University of Technology, Wageningen University and Research and Upp! UpCycling Plastic.
