1. A method performed in a local node of a waste management system, comprising
using radio signals of a radio interface unit of the local node for communication in the radio access network, wherein the radio signals are specified for radio access and communication in a radio access network;
using predefined information on one or more of said radio signals specified for radio access in the radio access network transmitted or received by the radio interface unit of the local node as radar input data, the said one or more of said radio signals being the same one or more of said radio signals used by the radio interface unit for the radio access and communication;
determining a distance from the local node to objects inside a container from the radar input data;
determining a fill state of a container from the determined distance;
generating an indication of the fill state of the container; and
transmitting the indication of the fill state of the container to a control node of a waste management system.
