Swapnil Jadhav, Director, SIDSA Environmental, discusses transforming waste into valuable resources through cutting-edge technology and innovative process solutions.

SIDSA Environmental brings decades of experience and expertise to the important niche of waste treatment and process technologies. As a global leader that is at the forefront of sustainable waste management, the company excels in recycling, waste-to-energy solutions and alternative fuel production. In this conversation, Swapnil Jadhav, Director, SIDSA Environmental, shares insights into their advanced shredding technology, its role in RDF production for the cement industry and emerging trends in waste-to-energy solutions.

Can you give us an overview of SIDSA Environmental’s role in waste treatment and process technologies?
SIDSA is a leading innovator in the field of waste treatment and process technologies, dedicated to delivering sustainable solutions that address the growing challenges of waste management.
SIDSA is a more than 52-year-old organisation with worldwide presence and has successfully realised over 1100 projects.
Our expertise is in the engineering and development of cutting-edge systems that enable the conversion of waste materials into valuable resources. This includes recycling technologies, waste-to-energy (W2E) systems, and advanced methods for producing alternative fuels such as refuse derived fuel (RDF). The organisation prioritises environmental stewardship by integrating energy-efficient processes and technologies, supporting industrial sectors—including the cement industry—in reducing their carbon footprint. Through our comprehensive approach, we aim to promote a circular economy where waste is no longer a burden but a resource to be harnessed.

How does SIDSA Environmental’s shredding technology contribute to the cement industry, especially in the production of RDF?
SIDSA’s shredding technology is pivotal in transforming diverse waste streams into high-quality RDF. Cement kilns require fuel with specific calorific values and uniform composition to ensure efficient combustion and operational stability, and this is where our shredding systems excel. In India, we are segment leaders with more than 30 projects including over 50 equipment of varied capacity successfully realised. Some of the solutions were supplied as complete turnkey plants for high capacity AFR processing. Our esteemed client list comprises reputed cement manufacturers and chemical industries. Our technology processes various types of waste—such as plastics, textiles and industrial residues—breaking them down into consistent particles suitable for energy recovery.

Key features include:

High efficiency: Ensures optimal throughput for large volumes of waste.
Adaptability: Handles mixed and heterogeneous waste streams, including contaminated or complex materials.
Reliability: Reduces the likelihood of operational disruptions in RDF production. By standardising RDF properties, our shredding technology enables cement plants to achieve greater energy efficiency while adhering to environmental regulations.

What are the key benefits of using alternative fuels like RDF in cement kilns?
The adoption of RDF and other alternative fuels offers significant advantages across environmental, economic and social dimensions:

Environmental benefits: Cement kilns using RDF emit fewer greenhouse gases compared to those reliant on fossil fuels like coal or petroleum coke. RDF also helps mitigate the issue of overflowing landfills by diverting waste toward energy recovery.
Economic savings: Alternative fuels are often more cost-effective than traditional energy sources, allowing cement plants to reduce operational expenses.
Sustainability and resource efficiency: RDF facilitates the circular economy by repurposing waste materials into energy, conserving finite natural resources.
Operational flexibility: Cement kilns designed to use RDF can seamlessly switch between different fuel types, enhancing adaptability to market conditions.

What innovations have been introduced in waste-to-energy (W2E) and recycling solutions?
SIDSA’s machinery is meticulously engineered to handle the complex requirements of processing hazardous and bulky waste.

This includes:

Robust construction: Our equipment is designed to manage heavy loads and challenging waste streams, such as industrial debris, tires and large furniture.
Advanced safety features: Intelligent sensors and automated controls ensure safe operation when dealing with potentially harmful materials, such as chemical waste.
Compliance with standards: Machinery is built to adhere to international environmental and safety regulations, guaranteeing reliability under stringent conditions.
Modular design: Allows for customisation and scalability to meet the unique needs of various waste management facilities.

How does your organisation customised solutions help cement plants improve sustainability and efficiency?
We consistently push the boundaries of technology to enhance waste management outcomes.
General innovations and new product development focus on:

Energy-efficient shredders: These machines consume less power while maintaining high throughput, contributing to lower operational costs.
AI-powered sorting systems: Utilise advanced algorithms to automate waste classification, increasing material recovery rates and minimising errors.
Advanced gasification technologies: Convert waste into syngas (a clean energy source) while minimising emissions and residue.
Closed-loop recycling solutions: Enable the extraction and repurposing of materials from waste streams, maximising resource use while reducing environmental impact.

What future trends do you foresee in waste management and alternative fuel usage in the cement sector?
Looking ahead, several trends are likely to shape the future of waste management and alternative fuels in the cement industry:

AI integration: AI-driven technologies will enhance waste sorting and optimise RDF production, enabling greater efficiency.
Bio-based fuels: Increased use of biofuels derived from organic waste as a renewable and low-carbon energy source.
Collaborative approaches: Strengthened partnerships between governments, private industries and technology providers will facilitate large-scale implementation of sustainable practices.
Circular economy expansion: The cement sector will increasingly adopt closed-loop systems, reducing waste and maximising resource reuse.
Regulatory evolution: More stringent environmental laws and incentives for using alternative fuels will accelerate the transition toward sustainable energy solutions.

JSW Cement has commissioned an additional 1 MTPA cement grinding unit in Nagaur, Rajasthan, taking the company’s total cement grinding capacity to 25.1 MTPA. The commissioning was announced on Tuesday, October 6.

The company said the new unit had increased the total cement grinding capacity at its Rajasthan plant to 3.50 MTPA. The expansion adds to JSW Cement’s production infrastructure as it continues to build capacity across its operating network.

The company’s total clinker manufacturing capacity, including capacity at its joint venture JSW Cement FZC, stands at 9.74 MTPA. Clinker is an intermediate material used in cement production, and its availability supports the company’s grinding operations.

JSW Cement is also pursuing a proposed merger of its listed subsidiary Shiva Cement with the company. The scheme, approved by the boards of the respective companies, involves issuing five fully paid-up JSW Cement equity shares for every 41 shares held by Shiva Cement shareholders other than JSW Cement.

The arrangement remains subject to shareholder and regulatory approvals. JSW Cement currently holds 66.23 per cent of Shiva Cement’s paid-up equity share capital, and the shares held by JSW Cement in the subsidiary will be cancelled under the proposal without any issue of JSW Cement shares against that holding.

The scheme has an appointed date of April 1, 2026, and the company has indicated that completion could take 12 to 14 months, depending on the receipt of approvals. These include clearances from stock exchanges, the Securities and Exchange Board of India, the National Company Law Tribunal and other applicable authorities, along with approvals from shareholders and creditors where required. JSW Cement shares closed at Rs. 113.15 on the BSE, up Rs. 2.05, or 1.85 per cent.
