The world's most climate-efficient zinc smelter is inaugurated

Today, the world's most climate-efficient zinc smelter is inaugurated. In recent
years, Boliden has made extensive investments with the aim of nearly doubling
zinc production at Boliden Odda in Norway. The inauguration is a key milestone
as it is Boliden's largest investment to be completed and one of Norway's
largest industrial investments on the mainland ever.

100 years ago, zinc production began in Odda, supported by the development of
hydropower in the region. Now a new era is beginning as the largest development
step ever in the business begins. In addition to a large amount of
infrastructure being built, primarily for logistics and energy, a new roasting
furnace and a new sulfuric acid plant, as well as a new cellhouse, have been
built. Furthermore, the leaching and cleaning plant and the foundry have been
expanded and modernized.


- This is a historic day from several perspectives. We will almost double the
production of the world's most climate-efficient zinc. This is zinc that will
primarily be used as rust protection in a variety of European applications and
thereby be part of a responsible climate transition of our common continent. At
the same time, this is a flagship for Norwegian industry to be proud of for
another hundred years, says Mikael Staffas, President and CEO of Boliden.

The investments will result in a production capacity equivalent to 350 ktonnes,
compared to the previous 200 ktonnes. In addition, additional metals will be
extracted from the raw material, which will result in less waste. Through the
increase in production, Boliden Odda will establish itself as Europe's second
largest and the world's most productive zinc smelter. The plant will produce
1,000 tonnes of cast zinc per full-time employee (FTE) each year.

Zinc is the world's fourth most widely used metal. The main area of application
is to protect steel structures against corrosion. The construction sector,
together with the automotive industry, is therefore the largest users of zinc.
In addition, the energy sector is a growing consumer of zinc, as wind turbines,
for example, are often located in environments exposed to corrosion. Other areas
of application include fertilizer, as a large amount of agricultural land
globally is zinc deficient. The addition of zinc thus contributes to higher food
production.
