Honestly, that's a pretty bold claim. Where did you hear most plastic can't be recycled? Tbh, I thought those numbers were a standard thing. It would be really helpful to know what makes them wrong. Feels like we're all just guessing if the system itself is broken.

Oh man, that's so true. I read an article once about how bakers say to feel the dough, not just follow the recipe time. It's the same idea, you gotta adjust for your actual conditions. That old guy knew his stuff.

That cheap caulk story is a perfect example.
