Thank you for the question.
What would be very important and interesting for the future is to look, for instance, into the production of plastic from other waste sources. For example, we have a lot of food waste and sewage sludge that we want to valorize now as well; we need to valorize organic waste through, for instance, processes like anaerobic digestion. In these processes, we can produce methane, but we can also basically stop the process earlier and produce hydrogen gas with volatile fatty acids, and these volatile fatty acids can then be used for fermentation by bacteria that can produce bioplastics. For example, PHA can be produced by that method.
In this way, we can produce bio-based plastics from organic waste materials, so we're not in any competition with food production, etc.
