India and Norway Explore Joint Technologies to Transform Industrial Waste into Sustainable Construction Resources

India and Norway are strengthening scientific and technological cooperation to transform industrial waste into valuable construction materials, advancing sustainable manufacturing, circular-economy practices and environmentally responsible infrastructure development.

The Council of Scientific and Industrial Research (CSIR), in collaboration with Norway’s SINTEF research organisation and the Research Council of Norway, organised the India–Norway Dialogue on Waste to Resource Solutions in the Cement and Construction Sector on 10 November 2026 at the India Habitat Centre in New Delhi.

The dialogue brought together scientists, researchers, regulatory authorities and representatives from the cement and construction industries to explore technologies for recycling industrial residues, managing hazardous waste and developing commercially viable construction materials from waste products.

The initiative forms part of the expanding India–Norway Green Strategic Partnership, established during Prime Minister Narendra Modi’s visit to Norway in May 2026, which places clean technology, circular-economy solutions and scientific research among the priorities of bilateral cooperation.

Transforming Industrial Waste into Valuable Construction Materials

A major focus of the dialogue was the transition from conventional linear production systems, in which materials are extracted, processed, consumed and discarded, towards a circular economy that recovers and reuses resources.

Prof. R. Pradeep Kumar, Director of CSIR-Central Building Research Institute (CSIR-CBRI), highlighted the importance of converting construction debris and industrial by-products into useful materials for infrastructure development.

The discussions examined the potential applications of construction and demolition waste, steel slag, fly ash, red mud and other industrial residues in manufacturing construction materials.

Steel slag, generated during steel production, can be processed for use in aggregates and certain construction applications. Fly ash from thermal power generation can serve as a supplementary material in cement and concrete production, while red mud generated during alumina refining offers potential applications in specialised construction products after appropriate processing and testing.

The researchers also examined challenges involving material-processing technologies, product standardisation, economic viability and market acceptance. Addressing these issues will be essential for translating laboratory research into commercially scalable technologies.

Using Cement Kilns for Hazardous Waste Treatment

An important technical session examined the potential of cement manufacturing facilities to support environmentally sound hazardous waste treatment.

The session, led by Dr. Kåre Helge Karstensen, Chief Scientist at SINTEF, and Dr. Ramesh Kumar, Chief Scientist at CSIR-National Environmental Engineering Research Institute (CSIR-NEERI), explored cement kiln co-processing technologies for treating suitable categories of hazardous waste.

The discussions covered Persistent Organic Pollutants (POPs), including DDT and materials contaminated with polychlorinated biphenyls (PCBs). These substances present significant environmental challenges because of their persistence, toxicity and potential to accumulate in ecosystems.

Cement kiln co-processing involves introducing compatible waste materials into controlled, high-temperature cement manufacturing processes. Under appropriately designed and monitored operating conditions, certain hazardous organic contaminants can be destroyed while suitable waste-derived materials substitute for conventional fuels or raw materials.

International experience presented by SINTEF highlighted the technological potential of using cement kilns for hazardous waste destruction while reducing dependence on conventional fossil fuels.

CSIR-NEERI presented India’s National Implementation Plan associated with the Stockholm Convention, the Construction and Demolition Waste Management Rules, 2025, and information concerning legacy persistent organic pollutants.

Participants emphasised that successful implementation would require rigorous technical protocols, carefully controlled industrial trials, continuous emission monitoring and compliance with applicable environmental regulations.

CSIR Research on Industrial Waste Recycling

Research presented by CSIR-Central Road Research Institute (CSIR-CRRI) and CSIR-Advanced Materials and Processes Research Institute (CSIR-AMPRI) demonstrated opportunities for converting industrial by-products into higher-value construction materials.

The research initiatives examined potential applications of fly ash, copper slag, red mud, plastic waste, steel grit and other industrial residues in road construction, geopolymer concrete, specialised aggregates and engineered building products.

Geopolymer concrete is an emerging construction material that uses suitable aluminosilicate-rich raw materials, potentially including certain industrial by-products, as alternatives to conventional cementitious binders.

Depending on the material formulation and production process, geopolymer technologies may help reduce reliance on conventional Portland cement while improving the productive utilisation of industrial residues.

The research discussions also highlighted the importance of developing reliable processing techniques, evaluating material durability and ensuring that recycled construction products meet appropriate engineering and environmental standards.

The participation of CSIR research laboratories provided an opportunity to connect ongoing scientific investigations with industrial requirements and potential commercial applications.

Recycling Construction and Demolition Waste

Another major area of discussion concerned the recycling of construction and demolition waste generated by infrastructure development, urban redevelopment and building activities.

Dr. Christian John Engelsen of SINTEF led a dedicated technical session examining international practices for construction waste recovery and recycling.

The discussions highlighted recycled aggregate-based construction products, mobile recycling facilities and advanced processing techniques designed to remove impurities from recovered construction materials.

Effective construction and demolition waste recycling can reduce the volume of debris requiring disposal while recovering materials suitable for selected infrastructure and building applications.

Mobile recycling units offer particular advantages because waste can be processed closer to demolition or construction sites, potentially reducing transportation requirements and handling costs.

Prof. S. K. Singh of CSIR-CBRI also presented research on the utilisation of slags and other industrial by-products in construction materials, highlighting opportunities to improve resource efficiency in the building sector.

The participants recognised that wider adoption of recycled materials would depend on consistent product quality, appropriate technical standards and greater acceptance among construction companies and infrastructure developers.

India and Norway Identify Priority Areas for Joint Research

The dialogue identified several areas for future scientific and industrial cooperation between Indian and Norwegian institutions.

One of the principal objectives is to develop two to three joint India–Norway research proposals involving CSIR laboratories, SINTEF researchers and relevant industry partners.

The proposed collaborations are expected to focus on practical technological challenges and the development of solutions that can eventually be demonstrated under industrial operating conditions.

Other priority areas include pilot-scale demonstration projects for hazardous waste treatment, technical guidelines for managing DDT- and PCB-contaminated materials, advanced processing of industrial residues and the development of waste-derived construction products.

The participants also emphasised strengthening collaboration between research institutions, universities, regulatory agencies and industrial enterprises.

Such partnerships could facilitate technology validation, support the development of technical standards and improve the prospects for transferring successful research outcomes into industrial applications.

The proposed research projects and pilot demonstrations remain future collaborative activities, with their implementation dependent on subsequent technical planning, institutional agreements and necessary approvals.

Supporting India’s Circular Economy and Sustainable Infrastructure Development

The India–Norway initiative is particularly relevant to India’s expanding infrastructure and industrial manufacturing sectors.

Large-scale construction, steel production, thermal power generation, mineral processing and other industrial activities generate substantial quantities of residues that require environmentally responsible management.

Technologies capable of recovering useful materials from these waste streams could reduce pressure on natural resources, improve industrial efficiency and support the development of more sustainable construction supply chains.

The utilisation of industrial by-products in roads, buildings and other infrastructure applications could also create opportunities for specialised recycling enterprises, construction-material manufacturers and technology developers.

At the same time, the safe treatment of hazardous industrial waste remains essential for protecting the environment and preventing long-term contamination.

The collaboration between CSIR and Norwegian research institutions offers an opportunity to combine India’s industrial research capabilities with international expertise in waste processing, environmental engineering and sustainable construction technologies.

The India–Norway Dialogue concluded with a shared commitment to advancing scientific cooperation, developing practical circular-economy solutions and encouraging the responsible utilisation of industrial waste.

As the two countries work towards joint research proposals and potential demonstration projects, the initiative could contribute to India’s efforts to strengthen resource-efficient manufacturing, reduce industrial waste and develop more sustainable infrastructure technologies.
