From what I’ve read PLA is only biodegradable under very specific conditions. I looked into it and you have to send it to a recycling center designed for PLA and its expensive to do so. I would assume microplastics would still be present too. Even though it can be sourced from plant matter its still plastic.
I just ordered my first TV ever, and its a smart TV of course. My first choice would be to not connect it to the internet, but my wife wouldn’t like that. So i think ill just put it on its own network and block as many domains that it uses to phone home with as i can, without breaking functionality.
