Biswas, who also chairs the Department of Energy, Environmental and Chemical Engineering at Washington University, and his research team have demonstrated the ability of nanostructured titanium dioxide to remove mercury with greater than 95 percent efficiency. Recently concluded tests in a pilot scale facility have further corroborated the results of the laboratory research.
Mercury is released into the environment in trace quantities from the burning of coal in electric-generating plants, Biswas said. The amount of titanium dioxide in the paint solids from the Chrysler plants would be sufficient to removed the traces of mercury.
Through its collaboration with Chryslers St, Louis assembly plants, Amerens 855-megawatt Meramec power plant is the first in the nation to generate electricity by burning paint solids recovered from an automotive manufacturing facility. In the initial phase, the project produces enough electricity to power 70 homes for a year.
