In general municipal garbage is a small fraction of all wastes. In Poland municipal garbage is just 10% of all (the rest is industry), and out of this 10% only 15% could be recycled. So, this effort to sort garbage has negligible effect, yet it is costly and resource consuming, so net effect on environment could be easily negative as compared with, say, incineration with energy recovery.
Going after chewing gums is just stupid from that perspective.
