When northern India’s agricultural fields begin to burn each harvest season, it signals more than just the onset of winter pollution. It underscores a deeper environmental and agrarian dilemma of how to manage surplus biomass sustainably without compromising soil health or atmospheric balance. Positioning itself at the intersection of waste management, clean energy generation, and soil revitalization, SPS BIO-CHEM finds both purpose and opportunity in these challenges.
Bioenergy with Agricultural Relevance
SPS BIO-CHEM operates a compressed biogas (CBG) plant in Yamunanagar, Haryana, utilizing a feedstock mixture of press mud from sugar mills, cattle dung, and rice straw. These waste materials, often regarded as pollutants, are processed through anaerobic digestion into biogas, primarily methane, which is then purified and compressed into CBG using Vacuum Pressure Swing Adsorption (VPSA) technology. “Enriched methane is an alternative to conventional industrial fuel and is also viable in the transportation sector as per the SATAT Scheme of Government of India”, says Rohit Singla, Founder & Director, SPS BIO-CHEM.
The company’s use of in-house developed microbial consortia for the acidogenesis and methanogenesis stages of digestion has significantly improved gas yield and reduced processing time. Coupled with advanced automation via SCADA systems and quality assurance through Gas Chromatograph analysis, it ensures its CBG meets rigorous industrial standards for safety and consistency.
This aligns directly with government mandates promoting clean energy and offers a commercially viable alternative to compressed natural gas (CNG), particularly in rural and semi-urban areas.
Integrated Fertilizers with Functional Utility
The digestate left after biogas production is not wasted, it becomes a powerful agricultural resource. SPS BIO-CHEM transforms this by-product into biofertilizers and biocontrol agents, by enriching Fermented Organic Manure (FOM) and Liquid Fermented Organic Manure (LFOM). Fermented Organic Manure (FOM) and Liquid Fermented Organic Manure (LFOM) is recognized under the Fertilizer Control Order and reclassified as organic carbon enhancers which help restore degraded soils by improving organic carbon content, microbial health, and nutrient-use efficiency. Phosphate Rich Organic Manure (PROM) delivers plant-available phosphorus in amounts similar to other alternate fertilizers.
“We are one of the first companies in India with an integrated plant producing CBG and PROM from FOM, a process that maximizes resource utilization”, says Rohit. The pathogen-free nature of these fertilizers, ensured by anaerobic conditions, protects beneficial microflora, further strengthening the case for transitioning away from chemical-based agriculture. With a strong emphasis on nutrient-use efficiency, its fertilizers ensure that applied nutrients are better absorbed by plants, enhancing productivity and return on input costs.
Engineering Legacy
Behind SPS BIO-CHEM is SPS Group, a group with deep roots in infrastructure engineering and real estate. This relationship brings technical strength to plant setup and optimization, and provides institutional trust for major government collaborations. The civil and architectural infrastructure at the Yamunanagar facility is a result of this synergy, reducing lead times and enabling scalability for future installations.
SPS BIO-CHEM is not attempting to reinvent the energy market, it is recalibrating the role of agricultural and industrial waste within it
A Vision for Green Transitions
SPS BIO-CHEM is not attempting to reinvent the energy market, it is redefining the role of agricultural and industrial waste within it. With a clear vision to support India’s transition from food security to nutrient security, the company promotes green agriculture alongside green energy. Through anaerobic digestion, it converts biomass into clean fuel and nutrient-rich agri-inputs, addressing both climate resilience and soil regeneration. Its dual focus positions the company as a catalyst for sustainable farming and carbon mitigation in India’s evolving bioeconomy.
