In addition to the question: Can I really throw failed PLA prints on compost? and anything else I've read about PLA biodegradability, what exact conditions are needed to achieve this?
I mean, oxygen can be bought, and exposure to high temperatures for a specific time or light conditions can be arranged in a DIY matter. So, what conditions need to be met precisely to achieve PLA biodegradation? So far, I've never seen anyone provide a comprehensive list of required conditions or a DIY method.
