CO2 Utilization for Environmental Innovation: From Waste Stream to Sustainable Solutions

Abstract This paper seeks to redefine the role of carbon dioxide (CO2), shifting its perception from a greenhouse gas to a versatile resource in environmental sustainability. Focusing on applications in construction, agriculture, renewable energy, and material science, the aim is to explore CO2's potential in creating environmentally beneficial products and solutions. Through a systematic literature review and analysis of recent technological advancements, the paper evaluates the environmental, economic, and practical aspects of utilizing CO2 in various industries. It highlights processes such as carbonation in concrete production, CO2 enrichment in greenhouses, conversion to synthetic fuels, algae cultivation, and its use in manufacturing carbon fibers, plastics, and polymers. The study uncovers substantial environmental benefits across CO2 applications. In concrete production, CO2-infused concrete shows a significant potential to reduce carbon footprint. Greenhouse CO2 enrichment has demonstrated considerable enhancements in crop yields. The synthesis of CO2 into fuels like methanol offers a renewable energy source, which can contribute to reducing fossil fuel dependence. Algae cultivation using CO2 has the potential to substantially increase biofuel yields compared to traditional crops. In material science, CO2-derived plastics and polymers present opportunities to decrease reliance on petroleum-based products. Carbon fiber production from CO2 also shows promise in reducing emissions in the automotive and aerospace industries. In developing the next wave of batteries and electric vehicles (EVs), using carbon dioxide (CO2) is emerging as a game-changer. The focus here is on turning CO2 into advanced materials for battery parts, like lithium-carbonate, which can store more energy for longer than current technologies. However, challenges related to scalability and economic feasibility must be addressed for widespread adoption. This paper provides a comprehensive and quantified overview of CO2's emerging applications, challenging traditional views and showcasing its potential in sustainable practices. It offers new perspectives for the petroleum industry to participate actively in the global transition towards sustainability, emphasizing CO2's role in the circular economy and its capability to transform from a pollutant into a valuable environmental asset.
