Juan A. Conesa is Professor of Chemical Engineering at the University of Alicante. During the last 25 years he has been developing his research work on issues related to the thermal decomposition of waste, both in pyrolysis and in combustion. In the year 2000, together with his research group, he pointed out the analytical techniques related to dioxins and furans. Since then the research group works on the analysis and formation and destruction of these compounds in thermal decomposition systems. He is the author of more than 190 scientific articles and has directed around 40 research projects and 13 theses in the field of waste recovery. Since 2015 he is the director of the research group "Waste, Energy, Environment and Nanotechnology (WEEN)" of the University of Alicante.
