What Den Ouden Groep does
Den Ouden Groep is a privately held Dutch family business founded in 1948, headquartered in Schijndel, Netherlands, and currently led by the third generation (seven cousins, grandchildren of founders Tein and An den Ouden). The company operates as a diversified environmental and infrastructure platform across five core divisions: Den Ouden Infra (public-space design and civil concrete construction), Den Ouden Bodac (UXO detection, archaeology, ecology, and soil remediation using proprietary 3D ground-penetrating radar), Den Ouden BraBob (ground and sediment stream management including large-scale soil applications), Den Ouden Organic (green waste processing at 15 Dutch production locations handling ~500,000 tonnes annually), and Den Ouden GrowSolutions (organic fertilizers, biostimulants, and mycorrhizal products distributed to 75+ countries, formed via the 2023 merger of Ferm O Feed and Plant Health Cure).
The group generates revenue through a combination of professional services project delivery (infrastructure and soil conditioning), transaction fees (green waste intake, soil brokerage), and product sales (compost, substrates, organic fertilizers, biostimulants, and SolidGreen open-paving substrates). Distribution combines direct field sales to government and enterprise clients, tender participation for public-sector projects, on-site retail/wholesale at 15 production locations, and dealer/distributor networks internationally. A joint venture with Royal De Heus is constructing a 70,000-tonne organic fertilizer facility in Tay Ninh, Vietnam, targeted for summer 2027. The company holds ISO 9001/14001, CE marking under FPR EU 2019/1009, BRL SIKB 7500, Trede 4 Safety Culture Ladder, and Trede 2 PSO certifications, alongside comprehensive organic certifications (Skal, EU 2018/848, Demeter, KRAV, BIO AUSTRIA, Bio Suisse, NOP, JAS). Customer base spans Dutch municipalities (Tilburg, Dordrecht, Oosterhout), regional authorities (Provincie Drenthe), water utilities (Brabant Water, Vitens), and global agricultural producers.

Den Ouden Groep competitors and assessment
Company assessmentBroad incumbents
- Royal HaskoningDHV: Global engineering consultancy with strong Dutch presence in water infrastructure, soil remediation, and environmental services. Comparable to Den Ouden Bodac and BraBob's soil-conditioning and remediation work but at vastly larger scale and advisory rather than operator-led model.
- Renewi: UK-listed multi-national waste-to-product company with significant Dutch operations in green-waste recycling, composting, and organics processing. Directly comparable to Den Ouden Organic's green-waste intake and compost output, but operates at much larger scale and broader geographic footprint across multiple waste streams.
- Valagro (Syngenta Biologicals): Global biostimulants and specialty plant nutrition company (now part of Syngenta), comparable to Den Ouden GrowSolutions' biostimulant and mycorrhiza portfolio. Larger international footprint and R&D scale but operates at higher price points in different crop segments.
- Heijmans: Larger Dutch listed infrastructure and construction company delivering civil concrete, roads, bridges, and public-space projects for Dutch municipalities. Comparable to Den Ouden Infra's municipal infrastructure work but at substantially larger scale and broader scope.
- SUEZ (waste and recycling): Global environmental services group with significant Benelux operations in waste collection, organics processing, and circular economy solutions. Comparable to Den Ouden Organic and Infra at a much larger international scale.
Direct peers
- Tauw Group: Dutch environmental consultancy providing soil investigation, remediation, and ground/sediment management services. Closest peer to Den Ouden Bodac's soil investigation and Den Ouden BraBob's ground-stream management activities.
- Attero: Dutch green-waste composter and organic-fertilizer producer with comparable intake volumes and composting operations across the Netherlands. Direct competitor for municipal green-waste contracts and producer of competing compost and digestate products.
- DCM (De Ceuster Meststoffen): Belgian/Dutch producer of organic fertilizers, soil improvers, and biostimulants for professional horticulture and agriculture. Directly comparable to Den Ouden GrowSolutions' organic fertilizer portfolio and European distribution channels.
- Van Vliet Groep: Dutch family-owned group active in green-waste processing, compost production, and landscaping services. Most structurally similar peer to Den Ouden Organic in business model and ownership profile.
Regional players
- Vandermoortele / Vandersanden (brick/concrete peers): Vandersanden is a large European brick manufacturer relevant to Den Ouden Infra's concrete and masonry construction activities. Comparison useful for assessing construction-materials supply chain dynamics but a partial overlap only with Infra division.
