- Since January 2026 Teijin Aramid switched its cooling systems to industrial water from Nobian's salt evaporation residual stream after a successful test phase.
- The change cuts annual drinking-water use by 80% (over 300,000 m³, roughly equivalent to 3,000 households) and trims total water consumption by about 10%.
- Project works included construction of an industrial water pipeline, adaptation of the drinking-water feed to the cooling basin, and installation of an automated cooling-water treatment unit.
- Veolia engineered the tailored cooling-water treatment, and the measure contributes to Groningen's business water-use reduction target of 1.5 million m³ per year.
Implementation
Since January 2026 Teijin Aramid switched its cooling systems at Chemie Park Delfzijl to industrial water from Nobian's salt-production evaporation residual stream after a successful test phase.
Water savings
The change cuts annual drinking-water consumption by 80%—over 300,000 m³, roughly equivalent to 3,000 households—and reduces total water use by about 10%.
Project scope
Work comprised construction of an industrial-water pipeline, adaptation of the drinking-water feed to the cooling basin, and installation of an automated cooling-water treatment unit that continuously monitors and adjusts water quality.
Partners and regional impact
Veolia tailored the cooling-water treatment to the new water quality; the measure contributes to Groningen's target to cut business drinking-water use by 1.5 million m³ per year and illustrates reuse of residual streams within the park.
