Brussels will require all phones sold in the EU to have replaceable batteries from 2027 – and use USB-C chargers

Per the article, there must be replacement batteries available for at least five years after the end of the product being available on the market. I don't think it would make much sense to keep tonnes of batteries in storage for so long. Presumably battery manufacturing would therefore have to continue over time. Maybe device manufacturers will try to share battery designs across device models so they don't need so many manufacturing lines?

Would be great if it means that I could swap out my device's battery after a few years and the new battery takes advantage of the improvements over that time.

Treated waste water sludge is very commonly used here in Sweden albeit using anaerobic digestion rather than regular composting. High temperature composting would kill any pathogens so you can absolutely get permission to use a composting waste system in small scales. For larger scale waste treatment it is with anaerobic digestion, as mentioned.

The captured methane is typically used for fuel, e.g., in public transport.

As far as I know the sludge used for fertilizer needs to be certified under something called REVAQ. Some controversy does exist surrounding safe levels of the various harmful substances and perhaps PFAS in particular.
