No one (including the manufacturer) knows how long it will last - 50 years is as far as accelerated aging can test to. You're assuming they split or break apart

No one (including the manufacturer) knows how long it will last - 50 years is as far as accelerated aging can test to. You're assuming they split or break apart. The posts themselves are recyclable, so maybe in 50 years someone can pull them out of the ground and recycle them?
- jcrben 1y agoThe point is that we know the weathering process will shed microplastics. https://magazine.hms.harvard.edu/articles/microplastics-everywhere https://magazine.hms.harvard.edu/articles/microplastics-ever...
- PlunderBunny 1y agoAbsolutely, and they admit this themselves. From their FAQ: "the rate of degradation is very, very slow – untreated plastics of the type used in Future Posts degrade in the environment by 1.3um to 22um (0.0013mm/year to 0.022 mm/year for HDPE and LDPE respectively). For the mix of plastics typically in a Future Post, that means the post will degrade at a rate of around 10% of thickness of a hair every year"
- garbagewoman 1y agoThink about what you’re writing and compare that to your experience with any non-uv stabilised plastic that has spent its life in the sun. For someone who implores for people to “think about it” you sure seem extremely easy to convince with a bit of marketing fluff
- PlunderBunny 1y agoI'm not convinced - I'm still thinking about it even now! The plastics, treatments, geometry etc make the posts quite different from the kind of plastics we find falling apart on the roadside etc.
