This looks very promising! Efficiently dehalogenizing toxins, preserving their carbon "skeletons" to be repurposed for valuable (nontoxic) industrial chemicals, creating NaCl (table salt) as a byproduct... seems full of win to me. Here's hoping...
Render me surprised as there is no Na in DDT.
Benzene is quite toxic. The EPA classifies benzene as a known human carcinogen for all routes of exposure. And their method leaves it buried it in the soil. It is not a valuable industrial chemical when it is in the soil, it is a pollutant.
