“…In our study, we consider blended cement as potential product, where CO 2 mineralization products serve as cement substitutes to replace conventional cement. 45 Blended cement offers a large market size in the gigaton scale with a good price. The life cycle stages are discussed in more detail in Section 3.1 and in the ESI, Section S2.…”

“…45 The blended cement with the mineralization products has been shown to fulll cement standards (e.g., ASTM C150 standard). 49 Still, the blended cement has also been shown to reduce performance for some applications: 45 Benhelal et al 45 showed that blended cement with 10% silicon dioxide (SiO 2 ) from mineralization has approximately 95% of the performance of pure ordinary Portland cement. The substitution credit considered in our study is thus 95% of the environmental impact due to production of ordinary Portland cement.…”

“…In order to solve or reduce the impact of CCS implementation challenges in Pakistan, it is recommended to academia and industries to initiate research activities to determine the most technical and economically viable process for CCS in this country. For example, there is no clear information available for exact energy consumption and costs of the carbon mineralization process, but initial assessment indicates that it consumes much less energy compared to the conventional CCS process (amine CO 2 process and geological CO 2 storage) and is more economically viable [25,28]. One of the promising aspects of carbon mineralization is utilizing by-products.…”

“…Magnesite and silica by-products of this process can be utilized for brick making and as a pozzolanic material for partial cement replacement. Utilization of these by-products can significantly offset the overall costs of CCS [28]. Pakistan can utilize its abundant coal reserves to provide the budget for CCS.…”

Reduction of Greenhouse Gas Emissions from Gas, Oil, and Coal Power Plants in Pakistan by Carbon Capture and Storage (CCS): A Review

The production of energy in Pakistan as a developing country mainly depends on consumption of fossil fuels, which are the main sources of greenhouse gas (GHG) emissions. These emissions can be mitigated by implementing carbon capture and storage (CCS) in running plants. An overview of the current and future potentials of Pakistan for CCS is provided, indicating a great potential for this technology to capture CO 2 emissions. The amine CO 2 capture process as the most mature procedure is currently applied in many oil and gas companies in Pakistan, which can be employed to capture CO 2 from other industries as well. Pakistan has a great CO 2 storage potential in oil, gas, and coal fields and in saline aquifer as well as significant resources of Mg and Ca silicates suitable as feedstock in the carbon mineralization process. For further development and implementation of CCS technologies in Pakistan, economic and policy barriers as the main obstacles should be alleviated.

“…Their research and technical facilities are centred at the University of Newcastle, Australia. MCi's suite of projects includes fundamental theoretical and laboratory research [66,[95][96][97][98][99][100] as well as one of the world's first mineral carbonation pilot plant facilities [101,102]. MCi's project has primarily been studying the carbonation of serpentine, which as mentioned above is an abundant mineral in New South Wales (NSW), Australia and globally [102].…”

Carbon capture, utilisation and storage (CCUS) via mineral carbonation is an effective method for long-term storage of carbon dioxide and combating climate change. Implemented at a large-scale, it provides a viable solution to harvesting and storing the modern crisis of GHGs emissions. To date, technological and economic barriers have inhibited broad-scale utilisation of mineral carbonation at industrial scales. This paper outlines the mineral carbonation process; discusses drivers and barriers of mineral carbonation deployment in Australian mining; and, finally, proposes a unique approach to commercially viable CCUS within the Australian mining industry by integrating mine waste management with mine site rehabilitation, and leveraging relationships with local coal-fired power station. This paper discusses using alkaline mine and coal-fired power station waste (fly ash, red mud, and ultramafic mine tailings, i.e., nickel, diamond, PGE (platinum group elements), and legacy asbestos mine tailings) as the feedstock for CCUS to produce environmentally benign materials, which can be used in mine reclamation. Geographical proximity of mining operations, mining waste storage facilities and coal-fired power stations in Australia are identified; and possible synergies between them are discussed. This paper demonstrates that large-scale alkaline waste production and mine site reclamation can become integrated to mechanise CCUS. Furthermore, financial liabilities associated with such waste management and site reclamation could overcome many of the current economic setbacks of retrofitting CCUS in the mining industry. An improved approach to commercially viable climate change mitigation strategies available to the mining industry is reviewed in this paper.
