This separates medium and large-sized waste that has come out of the multi-stage trommel into three types: flat and light packaging, fine and rolling waste. Flat and light packaging includes, amongst others, folded bags and card. Rolling waste includes cans and plastic jars. Fine waste mainly means organic waste. Flat and rolling waste continue with the pre-treatment to completely separate them by material. Fine organic waste is put together with the small waste from the multi-stage trommel and is sent for wet pre-treatment.
Flat, sloping paddles with holes make the waste jump so that the rolling waste falls back, the flat and light waste goes up, and the fine waste falls through the holes.
