Major step in sustainability at Chemie Park Delfzijl: Teijin Aramid reduces drinking water consumption by 80%

Teijin Aramid has taken an important step at Chemie Park Delfzijl in making its operations more sustainable. Since January 2026, the company has been using a new, alternative water source for its cooling systems. As a result, annual drinking water consumption will fall by 80 percent, a saving of more than 300,000 m³. This is equivalent to the annual drinking water consumption of approximately 3,000 households.

Industrial water from salt production as a new water source 
The alternative source consists of industrial water derived from the evaporation process used in Nobian's salt production. This residual stream is given a high-quality, sustainable application within Teijin Aramid's cooling process. The circular water solution was developed in collaboration with Veolia and Nobian. This leads not only to a significant reduction in drinking water use, but also to an additional 10 percent reduction in total water consumption.

Important for the region's drinking water challenge 
In the Groningen region, demand for drinking water is increasing due to climate change, a growing number of households, and a strong economy. Water company Groningen is therefore working on various measures to restore the balance between supply and demand. One of these measures is reducing drinking water use by businesses by 1.5 million m³ per year. The change at Teijin Aramid makes a direct and substantial contribution to this goal. For Teijin Aramid, this change aligns with its sustainability ambitions and strategy to make processes more future-proof and efficient.

Intensive collaboration at Chemie Park 
The project consisted of three components: the construction of an industrial water pipeline, the adaptation of the drinking water supply to the cooling water basin, and the installation of a new automated cooling water treatment unit that continuously monitors and adjusts water quality. Veolia tailored the cooling water treatment to the new water quality of the industrial water from salt production, ensuring that the cooling system can continue to operate reliably and efficiently. Following a successful test phase, the complete system has been operational since January 2026.

Collaboration delivers regional and social benefits 
The project demonstrates how organizations at Chemie Park can jointly achieve solutions with clear societal and regional impact. By making smarter use of residual streams, pressure on the regional drinking water supply is reduced and concrete steps are taken towards making industrial processes more sustainable. This underscores the strength of the integrated chain of companies at Chemie Park.
