In a significant move towards environmental sustainability, the Council of Scientific and Industrial Research (CSIR) is spearheading initiatives that not only address pressing waste management issues but also contribute to the nation’s infrastructure development. The utilization of Waste Foundry Sand in road construction is a prime example of how industrial by-products can be transformed into valuable resources, reflecting a commitment to a circular economy.
CSIR-Central Road Research Institute (CSIR-CRRI) has taken the lead in this innovative project, collaborating with the Institute of Indian Foundrymen (IIF) and Suyog Elements India Pvt. Ltd. The initiative aims to convert Waste Foundry Sand, a by-product of the metal casting industry, into a sustainable material for road construction. This is particularly crucial as the Coimbatore foundry cluster, which houses around 800–1000 foundry units, generates significant quantities of foundry sand waste.
Dr. N. Kalaiselvi, a prominent figure in this initiative, stated, “The utilization of industrial by-products like Waste Foundry Sand in road construction reflects CSIR’s commitment to sustainable development and circular economy.” This collaboration not only promotes environmentally sustainable practices but also reduces dependency on natural aggregates, which are often limited and costly.
Moreover, CSIR-National Aerospace Laboratories (CSIR-NAL) has made strides in drone technology by transferring technology for the QPlane eVTOL drone to KRR Aerospace for mass production. This drone, designed for multi-sector use including defence, agriculture, and logistics, features fully electric propulsion and vertical take-off and landing capabilities. With an operational range of around 20 km, the QPlane is set to revolutionize various industries.
Dr. Ch. Ravi Sekhar from CSIR-CRRI emphasized the importance of such initiatives, stating, “CSIR-CRRI has been at the forefront of developing sustainable and innovative road technologies.” The project not only addresses the challenges of waste management but also aligns with the Government of India’s vision for a circular economy and green infrastructure.
Sushil Sharma, another key player in this project, noted, “This project aims to address these challenges by enabling the scientific reuse of foundry sand in road construction, thereby converting waste into a valuable infrastructure resource.” This reflects a growing recognition of the need for sustainable practices in infrastructure development, which is vital for the future of urban planning in India.
Reaction from the field
The collaborative efforts between CSIR, IIF, and other stakeholders are expected to set a precedent for future projects aimed at sustainability. As these initiatives unfold, they will likely inspire further research and development in the field of sustainable materials and technologies. However, details remain unconfirmed regarding the full impact and scalability of these projects.
