| Abstract | |
Steel and cement industries are essential for developing economies and challenges for global climate change mitigation. Low carbon (LC) forecasting that couples steel and cement, focusing on circular economy (CE) and industrial symbiosis (IS) concepts, are scarce. Considering such concepts, this paper proposes an intersetorial model for these industries, based on the Brazilian case. The findings indicate sustainable charcoal-based steelmaking as the greatest CE emissions abatement measure. Regarding IS, we have found that the more fly ash is available, the lower is the average abatement cost, but such an strategy is not gainful for overall abatement, given sizable coal-fired power plants' emissions. CE and IS can avoid 2.75 billion tCO2e or 52% of the businessas-usual emissions up to 2050 at US$ 10/tCO2e by intensifying existing processes in Brazil. CE and IS approaches extend the opportunities for economic savings and carbon reduction, therefore they must be part of future LC portfolios. (AU) | |
