New process for reducing dioxins in the combustion process by adding sulfur-containing waste

Researchers from the ecological chemistry research institute of the GSF center
near Munich have developed a new process that significantly reduces dioxins in the exhaust gases of incinerators. Through
addition of non-toxic sulfur bonds, they have achieved a
reduction of dioxins up to 99%.

Since, on the other hand, ordinary household waste contains some
part of sulfur bonds, this process opens perspectives completely
news, in terms of recycling for the combustion of waste, but also
for other combustion devices such as coal-fired power stations. he
This would mean adding a portion of household waste to the fuel
selected containing these sulfur bonds to allow to reduce
the emanations of dioxins.

A patent has been filed in Germany at the European patent office,
constituting an important step in the exploitation of the results of this project
subsidized by the European Union. According to Karl-Werner Schramm, the
Director of the Institute of Ecological Chemistry of the GSF Center, he is
now necessary to carry out a series of tests on the scale of
industrial incinerators. Mr. Schramm and his colleagues are looking
an industrial partner making its facilities available for
continue their research.
