Still Bright Secures $18.7M Seed Funding to Scale Clean Copper Extraction

Why It Matters

If scaled, the process could dramatically cut greenhouse‑gas and toxic emissions from copper production while reducing reliance on overseas smelting, addressing both environmental and supply‑chain risks as global copper demand is projected to rise 40% by 2040.

Deal Summary

Clean‑tech startup Still Bright announced it has closed an $18.7 million seed round to advance its water‑based copper purification technology. The funding will support pilot and demonstration‑scale reactors slated for 2027‑2028, aiming to reduce the environmental impact of traditional copper smelting.
