Growing critical metals supply through protein-based waste recycling.

Get in Touch

01 · The Problem

Europe's critical metals supply is locked up by monopoly suppliers.

98%

EU Reliance

EU reliance on Chinese rare earths (2025).

76,000 t/a

Projected Demand

Projected demand for tech-enabling metals by 2040.

40%

EU Target

EU critical-metals refinement target for 2030.

02 · The Opportunity

We have more than enough resources. They're sitting in the waste.

1.8 Bn t/a

Mineral Wastes

Processing by-products stockpiled in landfills and dams.

16 Bn t/a

Mine Tailings

Legacy piles, sometimes rivaling primary ores in metal content.

21 Bn m³/a

Industrial Waters

Wastewater streams from pharma, petroleum, semiconductors.

03 · The Solution

Protein-based extraction — built for waste streams where hydrometallurgy struggles.
