    Yeah, except those are actually from polylactid and decompose completely without microplastic. Paper tea bags on the other hand are often mixed with polypropylene and ironically contain microplastic and don’t decompose completely. The best way is a tea strainer anyway

      Are you sure those aren’t nylon bags? Anyway I’ve found PLA’s biodegradability highly over rated. When Sunchips were doing those PLA bags I threw one into a worm bin, when I emptied the bin a year later it looked pretty much unchanged.

        Tbf: I’m from germany and can only speak for our local market.

        Yes PLAs decompose slow and waaay slower than advertising suggests and need certain conditions, but they are still the better choice over polypropylene.
