For a "lighter" Future
Relieve the strain on Environment
Today, no dedicated production plant exists worldwide, and no production and/or continuous supply in/for Europe is secured. Europe imports 100 % of scandium. The goal of the EU is to reach strategic independency with competitive prices.
The ScaVanger company will be the first scandium producer from acid chlorine-rich solutions, by-products from TiO2 pigment production in the EU. The first plant will be operated at an EU TiO2 producer site. It can be adapted to other chlorine TiO2 production sites.
This plant can supply about 21t/a of Sc2O3, which represents about 2/3 of the expected EU consumption in 2028.
The Scavanger plant concept can be adapted to other chlorine TiO2 production sites in the EU and worldwide.
ScaVanger contributes to the EU’s circular economy and green deal action plans.
Scandium is a scarce transition metal and a critical and strategic element for the EU. It is used essentially in Solid Oxide Fuel Cells (SOFC), Solid Oxigen Electrolysis Cells (SOEC), thin films for 5 G application, and aluminium-scandium alloys for the aeronautic and space industries.
Europe depends on 100 % of scandium imports mainly from China.
ScaVanger will ensure a stable, reliable and sustainable supply for scandium (Sc), but also vanadium (V) and niobium (Nb) for the European growing markets.

ScaVanger extracts and refines scandium, vanadium and niobium from acid chlorine solutions. The EU produces about 1.5 million tonnes of TiO2 pigments every year. Most of the residus, including valulable metals, are landfilled as filter cakes at high costs.
Material flow analyses will be performed for the critical elements scandium, vanadium and niobium during the project time at macro-meso and microlevel to develop material flow indicators.
Labscale tests and process tuning will be performed in 2021.
Pilot plant preparation and piloting is planned for 2022 and 2023.
Upscaling of metallothermic Sc and Nb extraction will be performed in 2022.
The ScaVanger process technology will be demonstrated at real scale in Q1/2024.
ScaVanger Company will start industrial operation in 2026.
This technology can be easily implemented in all chlorine-based TiO2 pigment production plants.
