What should we do with waste - dump it nationally or ship across borders to burn? Does it make sense economically - and how about climate? This rare and very interesting topic is discussed by PhD Amalia Alonzo and Professor Marie Münster, based in their two studies The climate footprint of imports of combustible waste in systems with high shares of district heating and variable renewable energy and The economic value of imports of combustible waste in systems with high shares of district heating and variable renewable energy. The studies were co-authored with Ciprian Cimpan, Maria Ljunggren Söderman and Hans V. Ravn as part of the TOPWASTE project.  In the Peer Review section, Marie recommends Harry van der Weijde/University of Edinburgh's webinars on energy and Dartmouth College's: Energy seminar series.
