All the stakeholders, including industries, have been forced to take serious action in preserving the environment. Therefore, recycle of waste into energy and valuable chemicals has become attention in industries throughout the world. This paper focused on the integrated-waste utilization in a sugar industry by capturing the CO2 from the boiler and absorbing it into the mineral solution extracted from filter cake (mud) for producing mineral carbonates with the capacity of 3000 tonnes sugarcane per day. The mud first undergoes the extraction using Ammonium Chloride (NH4Cl) to extract the minerals. The alkali extracted from the mud then will be converted into Calcium Carbonate and Magnesium Carbonate via mineralization. Simulation using Aspen® plus was carried out using stoichiometric (RStoic ) and yield (RYield ) reactor block to find out the heat duty, the thermodynamic feasibility, and the yield distribution. CaCO3 was produced from both methods with the yield of RStoic and RYield 0.718 and 0.676 mol CaCO3/mol CaO, respectively. Based on the capacity of 3000 tonnes sugarcane per day, the process could produce the desired CaCO3, approximately 210 kg/hr. The CO2 to mineralize 1 tonne of filter cake was 74.2 kg CO2, while the heat duty is 76.3 kWh for 2.8 tonnes filter cake/hr. The conceptual design is thermodynamically favorable and would be potential to be applied in sugar mills.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1088/1757-899X/823/1/012052[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
