Origin2023
ERCO Worldwide and Nouryon together supply approximately 62% of global sodium chlorate — the chemical converted to chlorine dioxide (ClO2) for pulp mill bleaching. This two-company concentration means that more than 60% of the world's toilet paper, tissue paper, and printing paper bleaching supply chain depends on the output decisions of two companies: Nouryon (Dutch-headquartered, private equity-owned) and ERCO (Canadian, privately held). Sodium chlorate production requires substantial electrical power (electrolytic process) and favors locations with low-cost hydroelectric power — which explains both Nouryon's Scandinavian and North American concentration and ERCO's Canadian and Pacific Northwest US facilities. If both companies simultaneously faced production disruptions — from severe weather (ice storms affecting hydroelectric supply), regulatory shutdowns, or accidents — the global tissue and printing paper supply chains would be impaired within weeks, as pulp mill bleach chemical inventories are typically 1-3 months. The tissue paper supply chain's dependence on two companies making one industrial chemical is a rarely-discussed concentration risk in consumer goods manufacturing.

ERCO's ClO2 generator installed base (~100+ pulp mills globally) creates a service-and-supply relationship that goes beyond simple chemical commodity sales: ERCO designs and installs the equipment that converts sodium chlorate to chlorine dioxide at the pulp mill, and then provides the sodium chlorate feedstock for decades of ongoing operation. This technology-plus-supply model creates deep customer dependency — a pulp mill using an ERCO ClO2 generator system is optimized for ERCO's sodium chlorate specification; switching to Nouryon's chemical requires equipment recalibration, potentially regulatory reapproval, and process adjustments. The same dynamic exists for Nouryon's Eka technology customers. The result is a market segmented by equipment installed base: some portion of global pulp mills are 'ERCO mills' and some are 'Nouryon/Eka mills' based on which ClO2 generator technology they adopted — and this equipment choice effectively locks in chemical supply for the life of the equipment. The most sophisticated bleaching chemical supply chain lock-in mechanism is not chemical IP or cost — it's equipment compatibility.
