Wisconsin, USA -- Europe burns heaps of garbage, getting lots of electricity and some heat. The United States does not. Proponents say incineration shrinks the waste and produces heat and electricity while reducing the need for landfills and the diesel-drinking trucks tasked with taking trash to often-distant burial grounds.

These folks acknowledge that incinerators were rather dirty 25 years ago, but note that current air emissions are below Environmental Protection Agency standards. In a modern garbage incinerator, a complex set of filters removes heavy metals and other pollutants; high-temperature operation reduces the output of ultra-toxic dioxins.
