Chemelot is an integrated chemical production site and innovation campus in Sittard-Geleen, the Netherlands. Originating from the former DSM site at Geleen, it has evolved into a large industrial cluster hosting multiple companies that manufacture base chemicals, polymers, elastomers, fertilizers, and specialty intermediates. The site provides shared infrastructure and services—including utilities, energy, logistics, maintenance, and safety—enabling efficient operations for tenants across interconnected plants and value chains.
Adjacent to the industrial park, the Brightlands Chemelot Campus focuses on research, development, and scale-up, offering laboratories, pilot plants, and support for startups and established R&D teams in materials science and process technology. Chemelot emphasizes coordinated site management and permitting, and its location offers strong connectivity by road and rail within the broader North West Europe chemical corridor. Ongoing initiatives at the site target improved sustainability and circularity, including process efficiency, electrification, recycling, and other emissions-reduction efforts.
Also known as Chemelot Foundation.
