Engineered pathways toward low-carbon footprint materials for sustainable applications: a review
摘要
Low-carbon footprint materials have become essential for advancing sustainable technology and industrial growth amid growing environmental and climate concerns. The pivotal role of low-carbon materials, ranging from conventional forms to advanced synthetic nanostructures such as graphene, facilitates innovations across renewable energy systems, construction materials, fossil-derived resources, and sustainable packaging. The importance of developing low-carbon technologies aligns with Sustainable Development Goals 7, 9, 11, and 13, which aim to achieve universal access to sustainable energy, infrastructure, and communities with a clean environment. The biobased materials, which include timber, bamboo, cork, straw bales, hempcrete, and mycelium composites, provide sequestration capabilities and low embodied energy. Recycled and waste materials-based alternatives for construction work, such as fly ash, recycled plastic, recycled aggregate concrete (RAC), and Ground Granulated Blast Furnace Slag (GGBS), have significantly reduced carbon emissions. Recent advances in carbon nanomaterials have opened new avenues in electrochemistry, catalysis, photodetection, solar energy harvesting, and hydrogen storage, owing to their high surface area, electrical conductivity, and functionalizing ability. Furthermore, integrating carbon-based systems in low-emission technologies represents a strategic pathway toward reducing greenhouse gas emissions and promoting a carbon-neutral economy. The aforementioned potential of low-carbon materials necessitates an understanding of various aspects of these materials, from synthesis to life cycle assessment, in order to contribute to a low-carbon future. Therefore, this review examines the underlying chemistry, structural design, and potential applications of low-carbon materials in modern sustainable technologies. It distinctly integrates low-carbon materials into a single outline that associates them with properties, applications, and lifecycle performance, providing an advanced roadmap for designing and developing low-carbon infrastructure using technological and biogenic advanced materials.
