CSIR‑CRRI Partners with IIF & Suyog Elements to Convert Waste Foundry Sand into Roads — Boosting India’s Circular Economy
The Council of Scientific & Industrial Research’s Central Road Research Institute (CSIR‑CRRI) has signed a Memorandum of Understanding with the Institute of Indian Foundrymen (IIF) and Suyog Elements to develop technologies for using Waste Foundry Sand (WFS) in road construction. The initiative aligns with India’s circular‑economy push, aiming to turn a hazardous industrial by‑product into a sustainable construction material, thereby reducing natural aggregate demand and improving waste management.
Overview The CSIR ‑Central Road Research Institute ( CSIR‑CRRI ) has entered into a collaborative research agreement with the IIF and private firm Suyog Elements. The MoU, signed in the presence of the Secretary of the DSIR and CSIR Director‑General Dr. N. Kalaiselvi , aims to develop and scale processes for incorporating WFS from the Coimbatore foundry cluster into road infrastructure. Key Developments Signing of a MoU among CSIR‑CRRI, IIF and Suyog Elements. Creation of a structured R&D programme to characterise different types of foundry sand (green sand, resin‑bonded sand) and devise processing protocols for road use. Goal to replicate the successful Steel Slag Road technology model for waste‑to‑wealth conversion. Commitment to provide technical validation (CSIR‑CRRI), industry outreach (IIF) and implementation scaling (Suyong Elements). Important Facts The Coimbatore cluster houses 800‑1000 foundry units, making it India’s largest source of foundry waste. WFS disposal poses significant environmental challenges due to its volume and non‑biodegradable nature. Utilising WFS can reduce dependence on natural aggregates, conserving river sand and gravel resources. The project supports the Government’s circular‑economy vision and green‑infrastructure agenda. UPSC Relevance Understanding this initiative helps aspirants in multiple GS papers: GS3 – Economy & Environment: Illustrates how industrial waste can be converted into a value‑added resource, linking waste‑management policies with infrastructure development. GS3 – Science & Technology: Showcases the role of CSIR as a bridge between research institutions and industry for technology transfer. GS2 – Polity & Governance: Highlights inter‑ministerial coordination (DSIR, Ministry of Road Transport & Highways) and the use of MoUs for public‑private partnership. GS4 – Ethics & Integrity: Emphasises sustainable development and responsible industrial practices, aligning with the principle of ‘development that does not compromise future generations’. Way Forward Complete laboratory characterisation of various WFS types and develop pilot‑scale road sections for performance validation. Formulate standards and guidelines for WFS‑based aggregates, enabling adoption by state highway authorities. Scale up through capacity‑building workshops for foundry owners and road contractors, leveraging IIF’s industry network. Monitor environmental impact and cost‑benefit metrics to inform policy revisions on industrial waste utilisation. By turning a hazardous by‑product into a construction input, the CSIR‑CRRI‑IIF‑Suyog Elements collaboration exemplifies science‑driven, sustainable infrastructure that can be replicated across other industrial clusters in India.

Overview
CSIR-CRRI ties up with IIF & Suyog Elements to turn waste sand into roads, bolstering circular economy
Key Facts
2026: CSIR‑CRRI, Institute of Indian Foundrymen (IIF) and Suyog Elements signed an MoU to convert Waste Foundry Sand (WFS) into road aggregates.
Coimbatore foundry cluster houses ~800‑1000 units, the largest source of industrial sand waste in India.
WFS is a non‑biodegradable by‑product; its utilisation can cut natural aggregate demand by up to 30% in road projects.
The partnership mirrors the earlier "Steel Slag Road" model, aiming for pilot‑scale road sections using processed WFS.
CSIR‑CRRI will provide technical validation, IIF will handle industry outreach, and Suyog Elements will scale implementation.
The initiative aligns with the Government’s circular‑economy vision and green‑infrastructure agenda under the Ministry of Road Transport & Highways.
The MoU was witnessed by the Secretary, Department of Scientific & Industrial Research (DSIR) and CSIR Director‑General Dr. N. Kalaiselvi.
Background & Context
India generates massive industrial waste, especially from foundries, posing environmental hazards. Converting Waste Foundry Sand into road material integrates waste‑management policy with infrastructure development, reflecting the circular‑economy thrust in GS‑3 (Environment, Economy) and the role of research institutions in technology transfer (GS‑3, Science & Technology).
