Types of Collection Systems
There are two types of garbage collection systems—the separate and the combined. Before deciding which is the better adapted to local conditions the method of disposal of all municipal waste—rubbish, ashes, dead animals, street sweepings and stable manure—must be considered. A further study should be made of the five combinations which have been adopted by American cities and which are outlined in the chapter on ash and rubbish collection. When garbage is collected separately, the method of disposing of it is by the reduction process, incineration or feeding to hogs. If it is collected with rubbish the two wastes must be incinerated. If ashes, rubbish and garbage are collected together the wastes are either dumped or incinerated.
