Data centers convert nearly all the electricity they consume into heat — yet most of that heat is still vented into the atmosphere.
We saw an opportunity to turn that wasted energy into value and built a solution to do exactly that.
Meet Spectra: a modular, tubular photobioreactor designed for the sustainable cultivation of microalgae. 🌱
In partnership with Data4 and University of Paris-Saclay, we set out to develop a biocircular model for data center waste heat reuse.
In May 2025, we successfully piloted Spectra using waste heat from Data4’s servers to cultivate Chlorella microalgae—demonstrating how digital infrastructure can directly support sustainable biological production.
