Waste to energy might have its place, but incineration has some rather nasty byproducts: carbon and numerous other air pollutants, some highly toxic, but most particularly the ash, components of which require disposal as hazardous/toxic waste.  This is expensive and ultimately a future threat to water supplies.  Beyond that, my experience has been that local authorities are often motivated to reduce costs of monitoring and enforcement.
Burning wood is only minimally efficient, and then only if transport distances are short, I believe.
