The location of an incinerator is often very controversial and most residents do not want one situated near to them. The problems they can bring include increased traffic to an area, which is specifically carrying waste for processing at the incinerator plant, a problem made worse if waste is imported from other regions. This itself is associated with unpleasant smells and an adverse effect on local land and house prices. This latter effect could just be perception, but who wants to relocate to an area which has a waste incinerator nearby? So incinerator locations are often very restricted and plans for new ones can become political hot potatoes.
