Incineration turns waste into toxic air pollution and toxic ash, which would be dumped in area landfills, making them even more toxic to groundwater than they usually are.
Incineration is the most expensive and polluting way to make energy or to dispose of waste. Real solutions like reuse, recycling and composting produce 10 times as many jobs as burning or burying waste. San Francisco just reached 80% diversion from landfills and incinerators through their zero waste program.
