Building on almost 40 years of NRR conferences, NRR2026 offers a premier venue to explore the latest biotechnological advancements in (waste)water management. Special emphasis will be placed on the role of curiosity-driven research as the foundation for groundbreaking technological solutions.

NRR2026 will bring together key stakeholders — from international academics to industry leaders, practitioners, and policymakers. With strong engagement from universities, research institutes, industry, and governmental agencies, NRR2026 will be a pivotal moment in accelerating the transition from research to real-world impact, providing a roadmap for resilient, sustainable, and climate-proof cities.
