**Summary:**
The Department of Science and Technology (DST) is considering the recommendation of an Expert Panel to establish five Carbon Capture and Utilization (CCU) testbeds within the cement sector across India. This initiative aims to reduce carbon dioxide (CO2) emissions from cement manufacturing by capturing CO2 and converting it into value-added products, including synthetic fuels, urea, soda ash, concrete aggregates, and food-grade CO2.
These testbeds will serve as platforms for validating and demonstrating CCU technologies at a small scale in real-world industrial settings through collaborations between industry and academia. The initiative directly supports India's goal of achieving net-zero emissions by 2070 by promoting a circular carbon economy and decarbonizing emission-intensive sectors like cement, which accounts for approximately 7% of the nation's industrial carbon emissions. The testbeds are designed to capture up to 2 tonnes per day (TPD) of CO2.
The Expert Panel's recommendations include the following sites, institutions, and technological solutions:
1. **JK Cement (Chittorgarh, Rajasthan):** Partnering with the National Council for Cement and Building Material, Ballabhgarh and the Indian Institute of Technology (IIT), Roorkee, to implement oxygen-based calcination to capture 2 TPD of CO2. It will be utilized 0.4 TPD in lightweight concrete products and olefins. Focus on solvent-based carbon capture technology.
2. **JSW Cement (Sundergarh, Odisha):** Collaborating with the Indian Institute of Technology (IIT), Kanpur, to capture 1 TPD of CO2 using solvent-based carbon capture technology and mineralize it into concrete using ICCM (Integrated Carbon Capture and Mineralization) technology.
3. **Dalmia Cement (Rajganjpur, Odisha):** Working with the Indian Institute of Technology (IIT), Bombay, to deploy a water-based catalyst-driven CO2 capture process at a scale of 2 TPD, integrating it within a live cement plant to convert captured CO2 into calcium carbonate, sodium bicarbonate, and formic acid.
4. **JSW Cement (Kurnool, Andhra Pradesh):** Partnering with CSIR-Indian Institute of Petroleum, Dehradun, Indian Institute of Technology (IIT), Tirupati, and Indian Institute of Science (IISc), Bengaluru, to employ a Vacuum Swing Adsorption (VSA) process for capturing 1 TPD of CO2 from cement kiln gas and utilizing it within the construction material value chain.
5. **Ultratech Cement Ltd. (Reddipalayam, Tamil Nadu):** Collaborating with the Indian Institute of Technology (IIT), Madras, and Birla Institute of Technology and Science (BITS) Pilani, Goa, to implement new kiln burning technology based on oxygen-enriched burning, adsorption-absorption capture, and mineralization of captured CO2 (2 TPD) using concrete blocks, waste concrete fines, and concrete plant sludge.
These testbeds are expected to generate valuable byproducts and enable Indian industries to adopt and scale up CCU technologies. The modular solutions developed have the potential to be replicated in other hard-to-abate sectors, including power, iron and steel, oil and natural gas, and the chemical industry.

PARLIAMENT QUESTION: CARBON CAPTURE
AND UTILISATION (CCU) TESTBEDS
Posted On: 23 JUL 2025 3:25PM by PIB Delhi
The Department of Science & Technology (DST) is in the process of considering the recommendation of the
Expert Panel for five Carbon Capture and Utilization (CCU) testbeds in the Cement sector in different parts of
the country. The objectives of these CCU testbeds are to capture Carbon Dioxide (CO₂) emission from cement
manufacturing and convert it into value-added products like synthetic fuels, urea, soda ash, concrete
aggregates, and food- grade CO₂. These testbeds are going to act as a platform for validating and
demonstrating CCU technologies at small scale in real industrial settings through Industry-Academia
collaborations. This initiative has significant relevance to enable Industrial decarbonisation in the country
with special focus on emissions-intensive sectors like Cement by promoting circular carbon economy, thereby
aligning well with India’s overarching target of net-zero by 2070.
The Expert Panel constituted by DST has recommended five CCU testbeds, and the Department is in the
process of considering the recommendations of the Expert Panel for further processing and financial
sanctions. The site-wise details of Institutions and Industry partners involved
in these recommended CCU testbeds along with proposed technological solutions to be deployed, are given

within India's cement sector, which constitutes approximately 7-8% of the Nation's industrial carbon
emissions. These recommended CCU testbeds are envisaged to demonstrate the carbon capture and utilization
at small scale i.e. up to 02 TPD (Tonnes Per Day). Apart from reduction in CO emissions, these testbeds are
2
expected to generate valuable by-products, such as synthetic fuels and construction materials, and thereby
contributing to the circular carbon economy.
Further, the successful implementation of testbeds is going to enable Indian industries to adopt the
technologies and scale up them to a full commercial level. These modular solutions have the potential to
replicate in other hard-to- abate sectors, including power, iron & steel, oil & natural gas, chemical industry,
etc. through customized engineering into pre-existing industrial frameworks.
