Sustainable zinc production expansion in Boliden Odda, Norway

Zinc is one of the most widely consumed metals in the world.

Zinc is an incredibly important metal for the development of a sustainable society, and it is used in e.g. in automotive, buildings and infrastructure.

Boliden is a Swedish mining and metals company with a focus on sustainable development. The company’s core competence lies within the fields of exploration, mining, smelting and metal recycling and it operates in Sweden, Norway, Finland and Ireland.


Boliden Odda zinc smelter expansion project

AFRY provides engineering and site services for the Boliden Odda zinc smelter expansion project. The expansion enables Boliden Odda to almost double zinc production and, at the same time, reduce already world-class low carbon dioxide intensity by 15 percent. Boliden has decided to expand the zinc smelter in Odda, southern Norway. The project named Green Zinc Odda will increase the annual production capacity for zinc products to 350,000 tonnes. In addition to zinc products, it will also enable extract of the bi-metals lead, gold, and silver. Boliden’s total investment value is EUR 700 million, and the project will be completed at the end of 2024.

We are extremely proud to be Boliden’s trusted partner in this strategic project. AFRY’s mission is to support transition towards more sustainable societies and this project is perfectly aligned with that target. Our operating model where local presence and knowhow is supported by global competencies enables us to deliver world-class solutions to Boliden
