Ultimate disposal of house and trade refuse is by:
Disposal into the sea. Special barges convey the rubbish well out to ‘sea, discharging it at such a distance that it will not be washed back to the foreshore.
Dumping, unless under stringent conditions, is objectionable as dumps become breeding grounds for rats. They are liable to catch fire. In time they may become overgrown and forgotten, and houses built on this undesirable site.
Pulverization. The refuse is mixed and crushed, and the resulting mass dumped.
Incineration. The refuse is consumed in a furnace; this is by far the best method, although incinerators frequently give off offensive odours. Cinders and clinkers are extracted by screens, and used for road construction.
