Emission-Reducing Material Innovations
Covation Biomaterials' CovationBio® bioPTMEG is Promising
Kalin Ned — October 11, 2025
Covation Biomaterials has provided a progress update on its new product — CovationBio® bioPTMEG — at the K 2025 plastics industry trade fair. The material is presented as a sustainable version of polytetramethylene ether glycol (PTMEG), a chemical traditionally derived from fossil fuels.
A key point of differentiation for Covation Biomaterials' CovationBio® bioPTMEG is its significantly reduced greenhouse gas emissions during production when benchmarked against conventional alternatives. The company reports that the product is entirely derived from biological sources and utilizes annually renewable resources. Specifically, the material relies on feedstocks like corncobs, which are agricultural byproducts that do not divert resources from the primary food supply chain, thereby mitigating a common concern associated with bio-based materials.
From a performance perspective, the bioPTMEG is described as a "drop-in" solution, meaning it is designed to be a direct substitute for fossil-based PTMEG without requiring downstream manufacturers to alter their existing production processes or equipment.
