In the quest for sustainable construction practices, a groundbreaking review article published in *Next Sustainability* (which translates to *Next Sustainability* in English) offers a promising avenue for reducing the environmental impact of Portland cement and concrete. Led by Sabrina A. Shaikh from the Department of Nuclear and Radiochemistry at Kishinchand Chellaram College, HSNC University in Mumbai, the research explores the potential of agricultural-origin functional additives as supplementary cementitious materials.
Portland cement, a cornerstone of modern construction, is notorious for its high energy consumption and substantial CO₂ emissions during the production of clinker, its primary constituent. Shaikh’s review highlights the critical need for decarbonization, energy efficiency, and resource optimization in the construction industry, aligning with several UN Sustainable Development Goals. “The construction sector is a significant contributor to global CO₂ emissions,” Shaikh notes. “By incorporating agricultural-origin materials, we can partially replace clinker and tune the properties of Portland cement, offering a greener alternative.”
The review delves into various agricultural-origin materials, including natural fibers, nanocellulose, lignin, plant extracts, agricultural waste ashes, and biochar. These materials not only serve as partial replacements for clinker but also enhance the properties of cement and concrete when used as reinforcement, fine aggregates, or supplementary components. Shaikh emphasizes the dual benefits of these materials: “They not only reduce the environmental footprint but also present economic advantages, particularly in regions with abundant agricultural waste.”
The article also presents SWOT analyses and life cycle assessments, underscoring the environmental and economic benefits of these materials. However, it acknowledges significant barriers to their widespread adoption, such as the lack of standardization and supply chain inefficiencies. “While the potential is immense, we must address these challenges to fully realize the benefits,” Shaikh states.
The implications for the energy sector are profound. By reducing the energy-intensive processes involved in cement production, these agricultural-origin materials can contribute to a more sustainable and circular economic model. The research suggests that future developments in the field could focus on standardizing these materials and optimizing supply chains to facilitate their integration into mainstream construction practices.
As the construction industry continues to evolve, Shaikh’s review offers a compelling vision for a more sustainable future. By leveraging agricultural waste, the sector can make strides towards decarbonization and resource efficiency, ultimately contributing to a healthier planet and more resilient communities. The publication of this research in *Next Sustainability* underscores its relevance and potential impact on the global stage.
