About Prinsenzwam
Prinsenzwam is a Breda-based circular-economy initiative focused on turning local organic waste streams into food and useful by-products. The company collects coffee grounds from businesses and organizations, uses them as a substrate for growing oyster mushrooms, and aims to keep the production and sales cycle local.
Its positioning is strongly rooted in sustainability and urban circularity: Prinsenzwam describes its mission as contributing to cleaner air, cleaner water, sufficient food, sustainable energy, comfortable housing, and meaningful employment. It presents itself as a practical local partner for organizations that want a useful destination for coffee grounds and a fresh, locally grown mushroom product in return.
Core Values
- Circular economy: Prinsenzwam is explicitly built around closing loops, turning waste into a new resource and keeping biological cycles separate from technical ones.
- Local collaboration: The company emphasizes local partnerships and local sales to reduce transport and strengthen circular chains in Breda.
- Sustainability: Its model is designed to reduce waste, limit transport, and make better use of residual streams in a practical way.
- Social and environmental balance: Prinsenzwam frames its work around people, planet, and profit, aiming for a balance between ecological, economic, and social value.
Unique Aspects
- Coffee grounds as a feedstock: Prinsenzwam uses used coffee grounds as the main substrate for oyster mushroom cultivation, giving a common waste stream a new food use.
- Urban circular loop in Breda: The company describes its model as an organic loop in the middle of the city, with local collection and local distribution keeping the chain short.
- Multiple residual streams: In addition to coffee grounds, it mentions using other residual organic materials with a high dry-matter content to support cultivation.
- Community and volunteer network: Prinsenzwam actively seeks contacts, volunteers, technical specialists, ecologists, and circular growers to help expand its sustainability efforts.
