Engineers like big machines and solving seemingly impossible problems, and I do not deny that waste management is a major problem, but there is a view that if we put all the country's waste into a big oven and light a fire, the smoke will go up the chimney and all our problems will be solved. The reality is that the ash produced in an incinerator by the burning process is much more toxic than any domestic refuse that would go to landfill. The introduction of incinerators will result in fewer landfill sites, but those landfills will hold waste that is much more toxic than anything we have seen previously. Nobody appears to be highlighting that problem in the debate on incineration.
