I researched what it would take to acquire our own plasma gasification to burn plastic among other waste streams for a true zero waste footprint community. It turns into a very complex system to prevent undesirable particulates like dioxins and furans from dispersing into the atmosphere when burning plastics, especially mixed plastics streams. The inert vitrified glassy rock has a far lower economic value per kg than if the plastic was downcycled into manufacturing feedstock. The maintenance on the systems was intensive and expensive, so between capex and opex, a community already consciously downcycling plastics back to feedstock would have to be quite large (>10K) before a plasma arc with heat co-generation plants would be economically prudent.
So this universal dynamic crosslinker is a welcome advance if we can use it to create upcycled feedstock in bulk. I see burning as a last resort; we should want to preserve the embedded energy in materials as long as possible in circular use and use the least possible increased embedded energy into them when transforming them again. It is much more economically efficient modeling the use pattern in this manner.
