About
I am Mateusz Wielopolski, a material scientist who spent fifteen years in polymers and now spends most of his attention on one gap: the distance between a working pilot and a plant that runs at price.
PhD in physical chemistry. MBA. Around thirty publications. Patents on bio-based materials. Co-host of Plastic. Climate. Future. and author of The Plastic Shift.
What I do here is narrower than that CV suggests. I read announcements the way a chemist reads them, looking for the constraint nobody mentioned — the temperature the enzyme needs, the feedstock already contracted to someone else through 2028, the cost per tonne that quietly decides whether any of it happens.
I publish every second week and send a monthly note. If you are building something in bio-based materials or biological recycling and have hit a wall that is not scientific, that wall is the thing I find interesting.
