Tapojärvi Innovation Challenge 2023

A Challenge for Students to reduce the environmental impact of the raw materials industry

Tapojärvi has embarked on a new journey in partnership with EIT RawMaterials to launch the Tapojärvi Innovation Challenge 2023 for Students to seek novel solutions for extracting valuable substances from waste or side streams in three areas of the raw materials industry: Stainless steel, Mining and Forest industry.

The call addresses teams consisting of two-to-four students with innovative ideas to reduce the environmental impact of these industries by finding new products and services based on wastes or side streams. The benefits of industrial circular economy solutions are directly reflected in the environmental impact, employee well-being, safety and economy.

Join us to achieve Zero Waste in the raw materials sector ! Apply by 14 April 2023

Tapojärvi's approach to circular economy

As a global forerunner in industrial circular economy, Finnish Tapojärvi provides circular economy solutions for the raw materials industry to contribute to reducing environmental impact.

Tapojärvi handles large quantities of processed materials from industrial side streams and implements circular economy services to give used materials a second or third life cycle.  Tapojärvi provides these valuable services for the steel, pulp and paper, construction, chemical, electronics and mining industries.

Scope of the challenge


Do you have an innovative idea to reduce the impact of one of the following three main areas?

Mining industry side streams

During ore extraction occurs waste rock and tailings. The future is recycling everything from side streams for re-use.

Do you have a solution for this?


Stainless Steel industry side streams

The residue of stainless steel production is slag, which mainly ends up in landfills.

Do you have a solution for using slag in products and services?


Forest industry side streams

In the forest industry, green liquor dregs are known to be the largest fraction of the inorganic residue in the kraft pulping process and energy generation from the wood-based residues generates a large amount of dry biomass fly ash. Do you have a solution to use forest industry side streams?

Students leading the future of resources circularity

This competition is ideal for any students concerned about  making a positive difference for the environment, who want to reduce the amount of waste and give back to humanity. The best teams will receive additional coaching for their solution with industry experts and compete for a chance to win a 10 000 € prize! The collaboration with Tapojärvi has the potential to be expanded to an internship role or even a more permanent employment.

Together, we can help turn your brilliant ideas into a reality, to extend the life of the planet’s precious raw materials!
