The topic of 'Certification' is relevant to the podcast episodes in several ways.

In the episode "Do you like your job?", the discussion touches on the rigorous certification processes involved in bringing new technologies, like electric aircraft, to market, and the financial hurdles associated with it.

The episode "Packaging and plastics in a circular economy with Olaf Boerner" focuses extensively on Flustix's certification process for plastic-free and recycled plastic products, and the importance of third-party verification.
