Abstract

Abstract: Algeria's interest in the global warming issue and its commitment to reduce its GHG emissions by 2030 requires research for operational solutions to support this effort. That entails establishing new urban planning tools, especially at the local urban scale. At the root of harmful Climate Change, cities must exploit their full potential to set up mitigation strategies. The interest of Industrial Symbioses in optimizing the industrial metabolism led us to explore such a potential for the operational urban planning needs focused on reducing CO2 emissions. This article aims to study the performances of a Low Carbon Urban Symbiosis (LC-UrS) at Algiers local scale. Based on a systemic approach, the study defines, firstly, the concerned urban system. Secondly, it explores its perimeter's symbiotic potential to build a database allowing develop the possible symbiotic scenarios and quantify their performance in energy optimization and CO2 emissions reduction. The gains are then estimated for each scenario. An urban design strategy for the considered optimal scenario is proposed under an action plan for LC-UrS. The results bring interesting answers for energy optimization and CO2 emissions reduction, with estimated rates of 30.5% and 13.27% per year, in Algerian's capital city case. This optimizing potential will be even more significant for other cities in the world, particularly with the increase in urban waste. However, implementing such a strategy would require background conditions. Highlights: UrS could be useful to realize global strategic climatic goals at the local scale. It offers more opportunities to loop flows between various activities than IS. Algiers' local case study proves its efficiency to reduce energy use & CO2 emissions. UrS should be incorporated into Algerian urban planning and energy management tools. Setting up an UrS would require an evolution of the local urban development policy.
