Every city, village or incorporated town may provide such method or methods as shall be approved by the corporate authorities for the disposition of garbage, refuse and ashes. Any municipality may provide by ordinance that such method or methods shall be the exclusive method or methods for the disposition of garbage, refuse and ashes to be allowed within that municipality. Such ordinance may be enacted notwithstanding the fact that competition may be displaced or that such ordinance may have an anti-competitive effect. Such methods may include, but need not be limited to land fill, feeding of garbage to hogs, incineration, reduction to fertilizer, or otherwise. Salvage and fertilizer or other matter or things of value may be sold and the proceeds used for the operation of the system. Material that is intended or collected to be recycled is not garbage, refuse or ashes. A municipality with a population of less than 1,000,000 shall not provide by ordinance for any methods that award a franchise for the collection or final disposition of general construction or demolition debris, except as allowed under Section 11-19-1.
