Your waste contains many different products, and therefore it makes good sense to sort. When you sort your waste, the materials can be reused. If, on the other hand, the waste is mixed together, it smokes for combustion, and then valuable materials go up in smoke.
Have you also considered where the empty butter tray should go? After all, it consists of both plastic and often a cardboard cover. If you separate the materials, the materials can be reused. The cardboard must be sorted under "Paper and cardboard", while the plastic tray itself must be sorted under "Plastic". If you do not separate the materials, the entire butter tray must be sorted under "Residual waste".
Good waste sorting.
