This is a great way to get microplastic through abrasion into even more places within the foodchain.
Wonder if it burns nicely too, plastic after all is "frozen gasoline" - here mixed with sand.

- hh3k0 4y agoThat's where my mind went first, too. We don't need more plastic in our lives, quite the opposite actually.
- yarg 4y agoIt could be probably be mitigated with some sort of coating. It would be more expensive, but it would still allow for the repurposing of waste plastic.
- moffkalast 4y agoAh I know, coat it in epoxy!
- 2muchcoffeeman 4y agoThere must be some applications though. Perhaps in the initial foundation which is probably waterproofed and underground? Or internal partitioning walls that get painted or plastered over?
- klyrs 4y agoCoat it in concrete!
- moffkalast 4y agoFirst in epoxy, then concrete, and then concrete mixed with epoxy for good measure.
- robbedpeter 4y agoThis is where you might use a variation of that "healing cracks" bacteria in conjunction with the "eats plastic" bacteria. If you could get the plastic digesting bacteria to excrete rigid oxides, then most of the plastic would be replaced with an interlocking 3d mesh of concrete and rock-like bacteria waste. https://www.sciencedirect.com/science/article/abs/pii/S0950061817313752 https://www.sciencedirect.com/science/article/abs/pii/S09500... It'd eliminate the plastic waste and leave much more environmentally friendly remains, and it'd be self healing.
- ProtoMathics 4y agoplastic can be infused with chemicals to not burn, but other than that youre right.
- coryrc 4y agoThose chemicals are usually the worst ones, PFAs for example...
- aliswe 4y agoAsphalt also emits microparticles during wear and tear, as do tires... It needs to be tested, not assumed.
- ajsnigrutin 4y agoAren't a lot of those microparticles just sand? Asphalt is basically just rocks/sand and some tar-ish cemicals to bind them together.
- rockinghigh 4y agoMost tires are made from synthetic rubber which also derived from oil.
- jahewson 4y agoNo you should assume it’s a problem until proven otherwise. We only have one environment and shoving anything we please into it without so much as a second thought is exactly what’s led us to our current predicament.
- throwaway742 4y ago>until proven otherwise a.k.a. testing
- aliswe 4y agowe know that the microparticles are a problem - the assumption that I'm challenging is that plastic is worse than conventional asphalt.
- ge96 4y agoI thought I saw somewhere it's also not a reliable load bearing material due to the random composition/possible empty pockets. I should check it they're extruding solid plastic bricks.
