Can sewage make tech cleaner ?

Author: BBC World Service July 22, 2025 Duration: 26:29

Thousands of tonnes of excess sewage, manure, food waste and paper sludge are being pumped hundreds of meters underground in the USA, where it will stay for centuries, preventing greenhouse gases from being released. Microsoft is backing the method to help offset carbon emissions. We speak to the co-founder and CEO of Vaulted Deep.

Also on Tech Life: We sound out some in the music industry about the impact of generative AI. And a high altitude Tech Life listener tells us about the time his tech went wrong.
