Integrating sugarcane-based bioenergy generation in Colombia with carbon capture and utilization technologies

Reducing local anthropogenic emissions to limit the danger to societies around the world is one of the main challenges of science and technology. Bioenergy with carbon capture and utilization is an approach that aims at harnessing two essential carbon sources in post-fossil scenarios: biomass and carbon dioxide, while looking for achieving global mitigation goals. Thus, this study presents, based on a literature review, an approach to a CO2 valorization chain integrating a cogeneration plant as CO2 source, absorption with amine solvent or calcium carbonate looping as options for carbon capture and its bioconversion in succinic acid. On a one-year basis, the results show that of the 628,7 kilotons of CO2 produced by burning bagasse, 452,7 and 402,4 tons can be captured at a cost of 34,6 and 58,3 US$/ton of CO2 captured by absorption with amine solvent or calcium carbonate looping respectively. Then, putting the captured CO2 to use in anaerobic fermentation produces close to one thousand kilotons of succinic acid per route. The development suggests a growth in the overall carbon conversion yield of the sugarcane industry but capture and using CO2 as feedstock does not automatically guarantee environmentally friendly processes then, there appear to be more challenges to take care before even considering the proposal.
