Reaction from the field
The Council of Scientific and Industrial Research (CSIR) is making significant strides in sustainable infrastructure and drone technology, with initiatives that could transform waste management and contribute to a circular economy in India. The most notable of these efforts is led by the CSIR-Central Road Research Institute (CSIR-CRRI), which is pioneering the use of Waste Foundry Sand in road construction. This initiative not only addresses the environmental challenges posed by industrial waste but also promotes innovative practices in infrastructure development.
Waste Foundry Sand, a by-product of the metal casting industry, has been identified as a valuable resource that can be repurposed for construction. The Coimbatore foundry cluster, known as India’s largest foundry cluster, generates significant quantities of this waste, with estimates suggesting there are between 800 to 1000 foundry units operating in the region. The collaboration between CSIR-CRRI and the Institute of Indian Foundrymen (IIF) aims to develop effective solutions for utilizing this waste, thereby reducing the dependency on natural aggregates and fostering environmentally sustainable practices.
Dr. N. Kalaiselvi, a prominent figure in this initiative, emphasized the importance of utilizing industrial by-products like Waste Foundry Sand in road construction, stating, “The utilization of industrial by-products like Waste Foundry Sand in road construction reflects CSIR’s commitment to sustainable development and circular economy.” This collaborative effort is expected to convert waste into a valuable infrastructure resource, aligning with the Government of India’s vision for a greener future.
In addition to its work with foundry sand, CSIR is also making waves in the drone technology sector. The CSIR-National Aerospace Laboratories (CSIR-NAL) has successfully transferred technology for the QPlane eVTOL drone to KRR Aerospace, paving the way for mass production. This drone is designed for multi-sector use, including applications in defence, agriculture, and logistics, showcasing the versatility and potential of drone technology in various fields.
The QPlane eVTOL drone features fully electric propulsion and is capable of vertical take-off and landing, making it an innovative solution for modern transportation challenges. With an operational range of around 20 km, this drone is set to revolutionize how goods and services are delivered, particularly in remote areas. Dr. Ch. Ravi Sekhar of CSIR-CRRI noted, “CSIR-CRRI has been at the forefront of developing sustainable and innovative road technologies,” highlighting the institute’s commitment to advancing infrastructure solutions.
As these initiatives unfold, the collaboration between CSIR, IIF, and Suyog Elements India Pvt. Ltd. is expected to yield significant advancements in sustainable infrastructure. The project aims to not only address the challenges of waste management but also to enhance the quality and sustainability of road construction across India. Sushil Sharma, involved in the project, remarked, “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.”
While these developments are promising, uncertainties remain regarding the full impact and scalability of these initiatives. As CSIR continues to push the boundaries of innovation in sustainable practices, further details on the outcomes of these projects will be closely monitored. The success of these initiatives could serve as a model for similar efforts globally, promoting a more sustainable and circular economy.
