Reduction of CO2 Emissions by Using Sugar Cane Bagasse Ash as Partial Cement Replacement

Cement production, mainly due to the calcination of limestone and burning of fossil fuels, is amongst the most carbon intensive industrial activities, being responsible for about 5% of global CO2 emissions. This paper presents a study on the viability of cement replacement by residual sugarcane bagasse ash. Furthermore, it investigates potential scenarios of CO2 emissions reductions in the manufacture of cement through the implementation of Clean Development Mechanism (CDM) projects, in accordance with the Kyoto Protocol. Studies of the thermal, chemical and mechanical behavior of concretes with 10 to 20% of ash indicated that there is improvement in the performance of all these properties and that the ash can be used as an admixture in cement manufacturing. Additionally, based on the official and applicable methodology, the CO2 emissions of two hypothetical scenarios of CDM project implementation using this technology in southeastern Brazil were evaluated. The results show that there are emissions reductions on the various scenarios, even for the worst, thus presenting evidence of the possibility of obtaining tradable carbon credits.
