About CT

We have done some amazing projects with a lot of impact over the years. In 2023 the company Circulaire Tuin stopped operating. Daniel van der Linden was the sole founder and owner of Circulaire Tuin. Daniel moved on to become part of Bluehive (OPG One Productivity Group) in 2023.

Below a summary of all the amazing projects we did.

2021 until 2023: Textile out, Green in Greening (trees, shrubs, insect hotels, play trees, etc.) is incredibly important for children's development and absolutely essential for a sustainable future. 🌍 We developed a program where primary schools can green their playgrounds for FREE by collecting textiles and earning points. The program gained national coverage and quickly had 150 participating schools.

2021: Terraces Just like in 2020, we've provided Rotterdam's restaurants with circular terraces.In 2021, we made 55 patios from recycled plastic, which lasts much longer than wood. After decades of use as patio furniture, it can easily be cast into a new mold to be reused as playground equipment or a garden bench, for example—how circular!

2020: Terraces In 2020, we built 275 terracces for the Municipality of Rotterdam, all made from recycled wood. No new wood was purchased. This allowed us to provide Rotterdam's hospitality industry with additional patio capacity during this year of COVID-19, allowing them to welcome more customers.

2019: Development of Marketplace for gardeners. Marketplace for used garden materials, such as 30x30 tiles, paving stones, and fences. This allows gardeners to trade their secondhand raw materials.
