InnoMax B.V.

What InnoMax B.V. does

InnoMax B.V. is a Netherlands-based engineering consultancy specializing in environmental and recycling technology, operating since 2003 from Velsen-Noord under the Du-Max Groep holding alongside sister company Du-Con Trade B.V. The firm is privately owned and led by founder and CEO Cees Duijn, who brings more than 35 years of experience in waste and materials recovery. InnoMax delivers advisory, basic engineering, project management and interim management services to recycling companies, large industrial enterprises, municipalities, healthcare institutions, and SMBs across the Netherlands, with selected international project work in Benelux, Germany, Denmark and developing markets (Myanmar, Nepal, Singapore, Malaysia) executed through partnerships and PUM volunteer missions.

The company's service portfolio spans waste diagnostics (Afvalscan), chemical-recycling advisory, sustainability reporting under CSRD/ESRS E5, medical-waste decontamination advisory (Blue2Green), custom sustainability advisory, and turnkey engineering for recycling installations. InnoMax also develops proprietary process technology, including the trademarked Windzifter-Unit (WZU) and Stijgzifter-Unit (SZU) air-separation installations co-developed by Cees Duijn and John van der Kolk, with the WZU having operated continuously for 30+ years at customer sites such as GP Groot. Two adjacent commercial platforms extend the core advisory business: Blue2Green, a collaborative label with Ecosteryl, Less2Care and Vinyl Recycling for medical-waste decontamination, and UQuip, an online marketplace for used recycling equipment launched with Du-Con Trade and Scratch Recycling Solutions.

InnoMax generates revenue through project-based, quote-driven professional-services engagements typically structured as multi-year contracts, with pricing determined by scope, complexity and client requirements rather than published tiers. The firm operates a field-sales go-to-market with on-site advisory visits across the Netherlands, supported by participation in trade events (Vakbeurs Recycling, IFAT, Plastic Recycling Show), industry publications and an ecosystem of strategic partners. As of January 2023 the team comprised five recycling professionals, with operations housed across two adjacent offices at Staalstraat 91 and 95 in Velsen-Noord. The firm carries no external institutional investment; its only disclosed non-dilutive funding is a €2 million EU Just Transition Fund grant awarded in 2024 to the Blue2Green medical-waste project.

Expansion highlights7 records

Broad incumbents

• Arcadis: Global design and consultancy firm with strong environmental and sustainability practices. Comparable as a broader environmental advisory incumbent that competes for the same circular economy and CSRD-related mandates, though with much broader portfolio and global footprint.
• Royal HaskoningDHV: Large Dutch engineering consultancy with a substantial environmental, sustainability, and waste management practice. Directly comparable because they independently validated InnoMax's medical waste approach and operate in the same Dutch environmental advisory market, but at vastly larger scale and broader scope.
• Ramboll: Global engineering, architecture, and environmental consultancy with significant waste and circular economy practices. Comparable as a broader incumbent competing for environmental and CSRD advisory work, though offering much wider service breadth.

Direct peers

• Tauw Group: Dutch environmental consultancy providing advisory, environmental impact assessments, and circular economy services to industry, municipalities, and developers. Most directly comparable peer given overlapping services (environmental consulting, permit support, sustainability advisory) and similar target customers in the Netherlands.
• CE Delft: Dutch independent research and consultancy organization specializing in environmental, transport, and circular economy policy. Comparable for the circular economy and sustainability research/advisory overlap, though CE Delft focuses more on policy analysis than implementation engineering.
• Nihot Recycling Technology: Dutch supplier of air separation and density separation technology for waste processing. Highly comparable as a fellow Dutch air-separation technology firm where Cees Duijn previously worked, with overlapping customer base in the Dutch recycling industry.
• Antea Group: Dutch engineering and environmental consulting firm offering environmental impact studies, permit support, and sustainability advisory. Comparable because of similar service mix targeting Dutch municipalities and industrial clients, though operating at significantly larger scale.
• Witteveen+Bos: Dutch engineering consultancy with environmental, waste, and water expertise serving public and private sector clients in the Netherlands. Comparable for its environmental advisory practice, though it focuses more on infrastructure and water projects than InnoMax's recycling specialization.

Regional players

• Eunomia Research & Consulting: UK-based environmental consultancy focused on circular economy, waste management, and resource efficiency. Comparable for circular economy and waste advisory services, but operating primarily in the UK market rather than the Netherlands.

Emerging players

• Duurzaamheidsfabriek: Dutch sustainability and circular economy advisory network supporting SMEs and municipalities with sustainability transitions. Comparable for the regional sustainability advisory overlap, though it operates as a community/network model rather than a focused consultancy.
