India produces 1.3 million tonnes
of used oil every year.
We are changing what happens next.
Santosh Petrochemical Innovations is commissioning India's Group II+ RRBO facility in Ghaziabad — converting used lubricating oil into premium base oil via vacuum distillation and hydrotreating. EPR-compliant. BS-VI ready.
Indian Oil
Santosh03 · WHO WE SERVE
Three audiences. One circular solution.
Group II+ RRBO that meets your formulation specs.
Procurement teams at lubricant manufacturers and blending companies need base oil that matches Group II+ virgin specs. Our hydrotreating process delivers the purity, VI, and low sulfur your BS-VI formulations require.
Turn your workshop's used oil into value — responsibly.
We collect used lubricating oil from garages, fleet operators, petrol pumps, and workshops across NCR and western UP. Fair price. Proper disposal. Full EPR compliance documentation provided.
EPR-compliant recycling with full audit trail.
MoEF/PCB auditors and corporate ESG teams need a recycler that's registered, compliant, and transparent. We provide EPR certificates, CPCB documentation, and environmental data on request.
04 · THE PROCESS
From used oil to Group II+
in six steps.
Indian Oil Technology powers our plant. Vacuum distillation with Wiped Film Evaporation, followed by catalytic hydrotreating — the same technology trusted by leading Group II+ producers in India.

Group I was sufficient for BS-IV. BS-VI needs Group II+.
Technical comparison: Group I RRBO vs Santosh Group II+
* Sulfur measured in ppm for Group II+, % for Group I. Group I RRBO spec per IFP Product Data Sheet (IS 1448 methods). Group II+ per API Base Oil Categories.
Hydrotreating removes what adsorption cannot
IFP and most Group I Indian re-refiners use acid clay or activated earth adsorption. This removes colour and odour — but cannot desulfurize or saturate aromatic structures. Hydrotreating reacts hydrogen with sulfur → H₂S, and saturates aromatic rings into paraffins. The result is chemically different oil.
BS-VI lubricants require Group II+ base stocks
India's BS-VI transition (April 2020) changed the base oil landscape. BS-VI engine oil grades for PCMO and HDO — API SN+, SP, CI-4+, CK-4 — require low-sulfur, high-VI base oils. Group I base stocks are insufficient for many modern OEM specifications.
The IOCL MOU validates our model
In March 2026, IOCL and Re Sustainability signed an MOU to build India's first national Group II+ RRBO circular economy. This directly validates Santosh's technology choice — Group II+ hydrotreating — as the direction India's leading oil company is committing to.
Re-refining uses 66% less energy than producing virgin base oil from crude. Every tonne of RRBO displaces virgin oil and reduces crude import dependency.
06 · SUSTAINABILITY
The circular economy
India is mandating.
India's EPR regulations under the Hazardous Waste Rules 2023 require lubricant manufacturers to blend increasing proportions of RRBO — starting 5% in FY2025, scaling to 50% by FY2031. Santosh is positioned to supply the Group II+ segment of this mandated market.
IOCL and Re Sustainability signed an MOU to build India's first national Group II+ RRBO circular economy — directly validating Santosh's technology and market positioning.
