Terrafame’s nickel sulphate production offers 60% lower carbon footprint than existing conventional processes

Our subsidiary fights climate change by enhancing low-carbon mobility with responsible battery chemicals.

IN TERRAFAME'S production process, the carbon footprint generated through the production of one kilogram of nickel sulphate is 1.75 kg CO2-eq(1, compared to the industry average of 5.4 kg CO2-eq.(2

The carbon footprint of 1 kg of Terrafame’s nickel sulphate corresponds to driving 10 km with an average petrol-powered passenger car(3. The value for industry average is 30 km/kg.

When Terrafame’s nickel sulphate hexahydrate is used in electric vehicle batteries, the annual savings in CO2 emissions correspond to a total of 3,400 million kilometres of driving with petrol car, i.e. approximately 85,000 journeys around the world.

– Terrafame will soon move downstream and start the production of battery chemicals in early 2021.
– A certified(4 life cycle assessment shows that the carbon footprint of Terrafame's nickel sulphate hexahydrate is more than 60% lower than that produced through conventional production technologies.
–Terrafame’s bioleaching-based production process uses about 90% less electricity and thermal energy in the production of nickel sulphate than the industry average.(5 
– Terrafame's integrated production process – which begins in its own mine and ends with battery chemicals production on one industrial site – is a unique and energy-efficient entity that provides customers with a transparent, traceable, and truly European battery chemical production chain.
