Transforming industrial waste into valuable resources through cutting-edge agglomeration technologies and expert environmental services.
Established on May 10, 2023, Green Sustainability Services Pvt Ltd (GSS) brings together elite professionals from Horizon Sustainability Solutions, former HARSCO personnel, and experienced steel plant employees. Our venture is financially backed by established Bhilai-based investors, providing the robust foundation needed to execute large-scale EPC projects.
Our core mission focuses on delivering customized waste and by-product agglomeration solutions, including advanced processes like Blending, Briquetting, Micro Pelletizing, and Vacuum Stiff Extrusion Briquetting (BREX).

We specialize in innovative technologies such as our proprietary Enclosed Slag Cooling Chamber (ESCC) process and state-of-the-art Metal Recovery Plants that extract valuable materials from industrial slag.
GSS offers comprehensive service models including Design & Engineering, EPC, Build-Own-Operate (BOO), Build-Own-Operate-Transfer (BOOT), and Operation & Maintenance (O&M) formats to meet diverse client needs.
Successfully refurbished, debottlenecked, and operated their DRI & Coal fines Briquetting Plant, significantly improving operational efficiency and waste recovery rates.
Provided comprehensive refurbishment, debottlenecking, and expert supervision services at their DRI fines Briquetting Plant, resulting in improved throughput and product quality.
Secured major contract for Design, Supply, and Project Supervision implementing our innovative Enclosed Slag Cooling Chamber (ESCC) technology – an advanced evolution of Steam Box Technology (SBT).
GSS is currently participating in bids for a wide range of customized service opportunities across nearly all major steel production facilities in India, expanding our footprint in the sustainable industrial solutions sector.
At GSS, we're committed to transforming industrial waste challenges into sustainable opportunities. Our mission centers on maximizing by-product recycling through innovative approaches and operational excellence.
We leverage deep industry knowledge and continuous innovation to create tailored solutions that address the unique needs of each client while optimizing resource recovery and minimizing environmental impact.
Combining subject matter expertise with innovative thinking to develop breakthrough solutions for complex waste challenges.
Creating co-developed solutions through customer intelligence and operational excellence to meet specific client needs.

The GSS team represents the perfect balance of full-time employees and specialized consultants, with plans to expand our roster of experts as we grow. With over 100 years of cumulative experience in by-product agglomeration, resource recovery, and outsourced services, our team brings unparalleled expertise to every project.
We've strategically identified experienced specialists for all key functions and specializations, ensuring comprehensive coverage for both our central management team and site operations.
Our team members have worked with industry leaders including JSW Steel Limited (Vijayanagar and Dolvi), AM/NS Hazira (formerly Essar), Vizag Steel, Harsco Environmental, and NMDC, bringing diverse perspectives and best practices to our operations.
Our Steam Box Process represents a breakthrough in slag management, reducing expansion by 50-60% within just 10 hours – significantly faster than conventional methods while delivering superior environmental performance.

Custom-designed slag pit and yard systems that ensure high safety standards, low emissions, reduced mobile equipment needs, and lower water consumption.
State-of-the-art dry metal recovery from carbon steel and stainless steel slag, plus wet processing systems for stainless steel slag (wet grinding) and ferro alloy slag (jigging).
Comprehensive O&M services for lime calcination plants, sinter plants, and pellet plants – a high-potential opportunity as outsourcing of non-core operations continues to increase across the industry.
Transformed waste materials into valuable resources through our advanced briquetting technology, creating compact, easily transportable briquettes that can be reintroduced into production processes.
Implemented our proprietary Steam Box technology to dramatically reduce slag cooling time while minimizing expansion issues, enabling faster processing and reducing environmental footprint.
These projects demonstrate our ability to tackle complex industrial challenges with innovative, effective solutions that deliver measurable environmental and operational benefits to our clients.

Compact footprint designs with optimized equipment configuration to reduce material handling costs while maintaining high production capacity.
Engineered to minimize emissions and material spillage throughout the processing cycle, supporting environmental compliance goals.
Designs focused on maintaining operations at rated capacity while minimizing off-spec material and product fines recycling requirements.
Lower specific power consumption (kWh/ton) and maximum safety features built into every system we design and operate.
Reduced mobile equipment requirements and fleet configurations designed to achieve lower fossil fuel consumption and reduced vehicle movement.
Streamlined operations requiring less manpower with minimized man-machine interfaces, enhancing both safety and operational efficiency.
Fewer bottleneck equipment points combined with lower O&M costs and reduced binder consumption for more sustainable operations.
Significantly lower water consumption, reduced fuel requirements for drying processes, and maximum plant uptime through preventative maintenance approaches.
Our plant designs integrate these advantages to deliver measurable improvements in operational efficiency, environmental performance, and cost-effectiveness for our clients.
We understand that different projects require different approaches. That's why GSS offers multiple engagement models to best fit your specific requirements and constraints:
Expert guidance throughout the design process with ongoing supervision to ensure proper implementation of sustainability solutions.
Comprehensive service including procurement assistance while maintaining our supervision-focused approach.
Professional operation and maintenance services for both new installations and revitalized existing plants.
Build-Own-Operate model for select opportunities where GSS takes full responsibility for implementation and operation.
