Burn or let them bury? The net social cost of producing district heating from imported waste

open access: yesEnergy Economics, 2022
In this study, a net social cost framework is applied to provide insights on policy issues relating to the cross-border trade in waste fuel. We estimate the net social cost of using imported waste fuel in a highly efficient combined heat and power plant (CHP) in a cold climate by considering both private costs and benefits as well as external costs ...
