Blue Stone Energy

Blue Stone Energy stands as a pioneering force in India’s clean-energy transition, being the first company in the nation to systematically collect Used Cooking Oil (UCO) for sustainable fuel production. With the active support and regulatory framework of FSSAI, which plays a critical role in standardizing and monitoring UCO collection across the country, Blue Stone Energy has helped shape the foundation of India’s circular bio-economy. As the first company to secure an official UCO collection contract from Indian Oil Corporation Ltd. (IOCL), Blue Stone Energy has set industry benchmarks for transparency, traceability, and large-scale operations. Today, as India evaluates a Sustainable Aviation Fuel (SAF) blending mandate—starting at 1% and projected to rise to 5% by 2032—BSE’s early vision and ground-level expertise position it at the forefront of supplying the essential feedstock required to power the next era of low-carbon aviation.

UCO (Used Cooking Oil)

The problem with reused oil

  1. Repeated reheating

    Cooking oil becomes harmful when repeatedly reheated or illegally reused in the food industry.

  2. Toxic compounds

    Once it exceeds safe limits, it forms toxic compounds like trans fats, free radicals, and aldehydes.

  3. Health risks

    Consuming food made with degraded oil can cause digestive issues, hypertension, heart disease, and long-term metabolic problems.

  4. Polluted drains & water

    Improper disposal of UCO clogs drains and pollutes soil and water, creating environmental hazards.

How Blue Stone Energy solves it

  1. Safe, compliant collection

    Blue Stone Energy addresses these risks by providing safe and compliant UCO collection services.

  2. Traceable under FSSAI & RUCO

    As India’s first organized UCO collector, it ensures responsible, traceable handling of used oil under FSSAI and RUCO guidelines.

  3. Turned into sustainable fuel

    Collected UCO is diverted to sustainable fuel production, preventing food chain contamination and creating value from waste.

Processing Plant

Blue Stone transforms used cooking oil into premium SAF feedstock through a proprietary ultra-refining process that combines impurity removal, advanced purification, glycerolysis, distillation, and ultra-fine filtration. This comprehensive approach eliminates solids, water, sulfur compounds, trace metals, and other contaminants while improving oil stability, delivering a high-purity, consistent feedstock that meets the stringent requirements of the Sustainable Aviation Fuel industry.
