The City of Yellowknife is currently landfilling all of its tires and plastics that are collected in the city.  Denesoline has proposed a system that would pyrolyze these materials into its basic constituents like pyrolysis oil, steel and carbon black.  Pyrolysis is an established technology and consists of heating the materials to a certain temperature in the absence of air.  Negotiations are ongoing with various stakeholders to establish at the very least a pilot plant to demonstrate the viability of this alternative to landfill which is not sustainable in the long run.
