Recycling industrial waste heat for sustainable district heating: a multi-actor perspective
Addressing the climate change and energy scarcity problems are two of the most complex sustainability challenges facing not only scientists, but also policy makers. Attempts at tackling these issues should be approached from two fronts: by increasing the energy efficiency (demand side) and by promoting the usage of renewables and non-Greenhouse Gases emitting energy sources (supply side). Usually, there is an agreement among stakeholders about sustainability in general, but there is a notable disagreement about how to achieve it. Thus, this paper proposes a multi-actor modelling and analysis approach as a way forward in systematically studying the system and actors dynamics – this is necessary in order to garner cooperation that will not only get such sustainability projects started, but that will also keep them going. A case study was employed to study the feasibility of using residual industrial heat for sustainable District Heating System. The result of the multi-actor analysis reveals that the Municipality (the initiator of the project) will have far greater success if it includes the perspectives of all the different stakeholders and encourage their participation from the early phases of project design and development.
