With Poplar Trees, a One-Time Polluter Makes Some Green
|
NORTH LIBERTY – Lou Licht was once a polluter – aiding and abetting companies that spewed toxins into the air and water.
Today he could hardly be greener.
With a quick-growing, toxic-zapping tree and a patented technique, Licht cleans up the types of messes he once helped create. His professional and environmental interests are wrapped up in trees, and he hopes to apply his work in Iowa.
