Andreas Tsangaris, BEng/80, MEng/83, is replacing landfills with power plants. In the quest for new sources of sustainable energy, he is sifting through the garbage. As chief scientist with Plasco Energy Group, Tsangaris co-developed a process to turn solid waste into fuel for electricity-generating engines—garbage in, electricity out. The conversion technique is about to go large-scale. The City of Ottawa and Plasco Energy Group signed a 20-year deal to divert 300 tonnes of garbage a day from landfills and convert it to energy. The project is scheduled to be operational by 2018.
