Home Best practices Harjavalta Industrial Eco-Park
Depending on the activities
This industrial park has been developing eco-efficiency activities for more than 60 years. It is located in Harjavalta, a town with a prominent mining sector.
The main tenants are copper and nickel flash smelters (Boliden), a nickel chemical producer (Norilsk Nickel), an energy producer (Porin Lämpövoima), a hydrogen plant (AGA), a sulphuric acid plant (YARA) and the town of Harjavalta.
In addition to these major actors that established symbiotic exchanges (energy cascading and material flows) the site also incorporates the services of more than 100 subcontractors. Many waste,and by-products outputs are used as resources: heavy metals, sulphur, sulphuric acid, slag, wastewater, etc.
