Data center operators are getting serious about waste heat and, more specifically, what to do with it.

While the solution for many is to pump it back into nearby district heating systems, other companies are getting more creative and using warmth from servers to heat aquafarms and greenhouses.

European operator Data4 has joined a project which aims to demonstrate that waste heat from its data center can help to grow algae, which could in turn be used as biofuel. Linda Lescuyer, Data4’s innovation manager, joins us to explain how the project is taking shape.
