The EU 1999 Landfill Directive is about the phase-out of biodegradable waste going to landfill. Nothing which composts or biodegrades should be disposed of this way.

These cups should not go in this waste stream, the only end of life is commercial composting as I don't believe they are suitable for home composting.
