In many countries people generally prefer their waste to be composted (provided, of course, the landfills are nowhere near their own backyards). But without costly plumbing, landfills produce copious quantities of methane, a powerful greenhouse gas that does more than 20 times the damage to the environment as comparable emissions of carbon dioxide. Modern incinerators capture the energy from solid waste as well as the emissions from the combustion. Such WTE plants burn rubbish at temperatures high enough (over 850[degrees]C) to break the molecular bonds in dioxins and other toxic chemicals and thus render them harmless. The flue gases are cooled in heat exchangers, producing steam to drive electricity-generating turbines. Why does America produce so much more rubbish? The difference is that in Europe and Japan it is manufacturers, rather than consumers, that are held responsible (via taxes on packaging waste) for the cost of processing the packaging used to wrap their goods. This gives them an incentive to use less of it. By contrast, in America, the cost of cleaning up the mess is dumped at the consumer's door. That, more than anything, is what needs to change.
