Solid and Hazardous Waste/Environmental Justice ! What are the consequences associated with landfills and incinerators? Landfills: groundwater contamination, methane generation, long-term viability, few new facilities opening and expensive to close Incinerators: though they take up 90% less space and can make steam to turn turbines, they have been wrongfully marked as "green". They are harmful to the environment -- Harmful Air Pollutants (HAPs) which include Carbon monoxide, dioxins,...
