Europe imports over 95% of its battery anode materials from China. That is not a supply chain problem. It is a strategic vulnerability.

Waste2Watt is a pre-seed deep tech startup and spin-out from TU Berlin and the University of Oxford. We are building a process to convert organic waste streams into high-performance hard carbon, the anode material of choice for next-generation sodium-ion batteries.

Our feedstock is what others throw away. Coffee grounds, agricultural residues, and other biomass waste that currently has no high-value end of life. Our output is a locally sourced, sustainably produced anode material for European battery cell manufacturers who can no longer afford to depend on Asian supply chains.

Why now? The EU Critical Raw Materials Act, the EU Battery Regulation, and a wave of new European gigafactories are creating urgent demand for domestic battery materials. Sodium-ion battery startups across Europe are actively searching for local hard carbon sources. That supply does not exist yet at scale. We are building it.

Why us? Our founding team combines materials science research from two of Europe’s leading universities with a deep understanding of the European battery value chain. We are female-founded, science-first, and mission-driven.

We are currently in the research and validation phase, conducting customer discovery interviews with European battery manufacturers and material producers.

If you are building in the battery space, sourcing anode materials, or investing in European deep tech, we would love to connect.

Trash in. Power out.
