Hello.

I am not an expert on recycling, but "energiajäte" or energy waste is going to be burned for energy. Therefore anything that burns is suitable for energy waste. For example plastic, wood and cardboard can be put there if there is not a separate container for them. I considered recycling:waste but if I understood correctly recycling:waste includes also non-flammable materials. Do you have any tagging suggestions?
