GBN

What GBN does

GBN Groep B.V. is a privately held Dutch circular materials company headquartered in Utrecht, founded in 1998, that processes construction, demolition, infrastructure, and contaminated-soil waste streams into certified secondary raw materials. The company serves municipalities, provincial governments, utilities, and civil engineering contractors, accepting material from infrastructure projects and redeploying it as certified circular products including Circugrind/Circuzand/Circument aggregates (via C2CA Technology co-developed with TU Delft), Vandolith cement-bound immobilisate from contaminated soils, cleaned railway ballast meeting ProRail's SPC-00033 specification, and circular infill sand and granulates from end-of-life artificial grass.

GBN's technology stack is built around four proprietary or co-developed processing capabilities: C2CA on-site concrete fractionation, Vandolith micron-level immobilization of contaminants, certified rail ballast cleaning installations in Roosendaal and Sappemeer, and the Netherlands' first artificial grass recycling facility in Amsterdam (operational since 2020). Operations are distributed across 12+ processing locations and depots, with revenue generated through transaction fees on material intake, sales of certified secondary construction materials, professional services via GBN Advies en Transitie, and rail infrastructure processing fees. Multiple revenue lines are operated through joint ventures — Grondstoffen Recycling Weert (with De Bloem-Group Panheel), Grondstoffen Recycling Burgum (with De Boer Burgum), and GBD Grondstoffen Alliantie (with Bontrup and Dirix).

The business model combines direct enterprise sales to project developers and government organizations with an inside-sales support function in Utrecht. All material outputs are delivered under sector-specific certifications (NL-BSB, BRL 9335, BRL 2506, Besluit Bodemkwaliteit, SPC-00033), which together form a meaningful barrier to entry. Pricing is quote-based and not publicly disclosed. Long-tenured framework contracts — including a 2025 four-year agreement with Enexis Netbeheer and Watermaatschappij Limburg (with an eight-year extension option) — provide multi-year revenue visibility, and the company's stated 'Mount 2030' goal is to reduce primary raw material use by 50% by 2030, aligned with the Dutch national 'Nederland Circulair' program.

Core offering

GBN handles the intake, processing, and recycling of soil, construction, and demolition materials in the Netherlands, converting these waste streams into certified circular raw materials and secondary construction products. The company operates a nationwide network of processing facilities handling concrete, contaminated soil, railway ballast, and end-of-life artificial grass, complemented by advisory and transition services for circular construction economics.

Product overview

GBN offers a comprehensive suite of circular economy solutions for the construction and infrastructure sectors in the Netherlands. The portfolio centers on circular material processing including Circulair beton (circular concrete using C2CA Technology developed with TU Delft), Circulaire grond (circular soil/ground), Circulaire bouwstof/Vandolith® (circular construction materials through immobilization), Circulaire spoorballast (circular railway ballast), and Circulair kunstgras (circular artificial grass recycling). These core products are complemented by Advies en Transitie consulting services, an Impact Report for tracking circular economy progress, and a network of recycling facilities including Grondstoffen Recycling Hoorn, Grondstoffen Recycling Weert, Grondstoffen Recycling Burgum, TOP Roosendaal, and specialized operations like GBN Artificial Grass Recycling (the first artificial grass processing factory in the Netherlands, established 2020) and Ballast Recycling Roosendaal. The offering is structured as a platform-plus-modules architecture where the core circular material processing services are the primary offering, with advisory services and impact reporting as complementary add-ons, and regional recycling facilities as specialized sub-brands.
