Why do owners charge slag removal fees for renovating properties?

The official name of the slag removal fee is: decoration garbage removal fee \x0d\ garbage removal is to be paid, which is borne by residents and handed over to the sanitation department \x0d\ Our ordinary "domestic garbage removal fee" is relatively small, so it is generally deducted from the water and electricity bill, so if we don't pay attention, we won't see this fee and think it is not; \x0d\ Decoration garbage can't be treated by ordinary methods, and its volume and weight are relatively large, so an extra "decoration garbage cleaning fee" is needed to deal with this kind of garbage; \x0d\ After the residents pay the fees, the property management company and the sanitation department (or a special removal company) will cooperate to clean up the decoration garbage;
