Where does our body heat go? Well at least some of it ends up down the drains that connect our homes to sewage networks, along with the heat from showers, washing machines and other household items. And that makes wastewater a potential resource.

This week on the pod we’re getting technical with Christoph Donner, CEO of Berliner Wasserbetriebe, as we delve into the science and regulations behind Berlin’s push to use wastewater to heat homes and businesses, including Ikea.

We also discuss the other good stuff that can be extracted from your sewage and the challenges that come with supplying water to a thriving metropolis.
