Episode description

Wastewater is a gold mine for energy, nutrients and water. Marc Wehmeijer dispels myths about breaking in to the wastewater industry, and takes us on a tour of the global wastewater treatment landscape from the deserts of Durango, Mexico to the Swiss Alps.

Marc Wehmeijer is the CEO of ThinkTIM, a company that designs, manufactures, installs and services wastewater treatment recycling units. Wehmeijer advocates for the use of artificial wetlands as treatment methods and to promote biodiversity. He emphasises wastewater as a 'microbiological zoo', detailing how we can extract phosphates from wastewater and use excess sludge to produce energy. 
Additionally, he promotes segmenting wastewater treatment processes with the end use in mind - for example, not using portabilised water for crop irrigation. The key message of wastewater treatment being: decentralise, segment and capitalise to the full extent!

The Living Revolution brings you scientists, industry leaders and entrepreneurs working on engineering biology to solve the world’s most pressing challenges. Listen in to hear the trials and successes of the bioeconomy.
