Make an impact with us
Our
Story
VSCA’s mission is to significantly lower CO2 emissions in the light metals industry.
This will have a major impact on three of the UN’s Sustainable Development Goals:
​
- Industry, Innovation & Infrastructure
- Responsible Consumption & Production
- Climate Action
.
Everyday day materials
Light metals such as aluminium and titanium are key materials in all our lives. We use them every day.
When we drink a can of cola, when we wrap our food in aluminium foil, when we drive our cars to work and when we fly in planes. Some people even have titanium implants in their bodies.

Radical solutions needed to
reduce CO2
​
Because of their high strength and low density, light metals are becoming increasingly important in the transport sector to make cars, trucks and planes lighter and more fuel efficient.
​
Energy intensive, producing CO2 emissions
However, the primary production of these light metals is very energy intensive and unfortunately produces greenhouse gases (GHG). For example, huge amounts of electricity are needed to convert aluminium ore (bauxite) into aluminium metal. And because aluminium smelters use carbon electrodes, CO2 gas is an unavoidable by-product of the conventional Hall-Héroult process.
As a result, each kilogram of aluminium metal produced today typically generates 15 kilograms of CO2 emissions.- The titanium industry is even more energy intensive, and the conventional Kroll process for producing titanium sponge also produces large amounts of CO2 and chlorine-based pollution.- Cleaning up the light metals industry by further reducing greenhouse gas emissions and other forms of pollution is timely. But it requires radical solutions.
