Perstorp inaugurates facility for purifying wastewater in Sweden

Sweden’s Perstorp has opened a facility that will enable wastewater from the water treatment plant run by the municipality to be further purified and reused for cooling at the Perstorp Oxo production plant in Stenungsund. This will save 1.1 billion l/year of freshwater.

Each production plant utilises water for various purposes, including serving as a solvent for chemical reactions, a carrier for products, a heat-transfer medium, and for cooling, among other uses. The scarcity around fresh water is present everywhere in the world, and the chemical industry have the opportunity and responsibility to create solutions when it comes to reducing the freshwater consumption.

Perstorp says it invested in this project in Stenungsund and now with this facility fully up and running it will save fresh water every year. This is an investment that Perstorp plan to implement at more sites around the world, to reduce freshwater consumption.

The recycled water will be used for production of renewable hydrogen via electrolysis for Perstorp’s transition project Project Air, as well as for other strategic investments.

The project is a key enabler to combining business growth and sustainable development, and to ensure a future water supply for the Stenungsund plant.

It adds that the 30% decrease in fresh water usage aligns with Perstorp’s long term ambition to become Finite Material Neutrality.
