Because recycled polymers are not just materials, they are histories of processing.
Every cycle introduces:
πchain scission
π oxidation
π molecular weight reduction
And the result is not subtle:
❌ unstable melt flow
❌ inconsistent cavity filling
❌ higher shrinkage variability
❌ increased reject rate
This is why most recycling solutions collapse at the production scale.
Not in the lab.
But on the injection molding machine.
The real challenge is not using recycled content.
It is restoring process stability.
When properly engineered:
✔️ rheological behavior becomes predictable
✔️ thermal degradation is controlled
✔️ surface quality is consistent
✔️ scrap and energy per part are reduced
This is where sustainability becomes real.
Not as a material choice but as a process-controlled system.
