Castrol India Limited and Tata Motors have signed a memorandum of understanding (MoU) to jointly launch a pilot programme for a used oil circularity ecosystem. The collaboration aims to establish a structured, traceable system for the responsible collection, channelisation, and recycling of used engine oil from Tata Motors' authorised service network in Karnataka. This initiative addresses the long-standing gap in managing used oil, a material classified as hazardous waste, by creating a credible and scalable model linking collection to high-quality re-refined output.

Under the agreement, Tata Motors' authorised sales and service touchpoints in Karnataka will serve as structured collection points for used engine oil. Castrol India will anchor the channelisation of the collected oil to registered recyclers. The pilot leverages Castrol India's lubricant expertise and insights from previous used-oil collection pilots in southern India to ensure quality and traceability throughout the recycling process.

Strategic Collaboration for Sustainability

The MoU builds on the existing relationship between the two companies and reflects a shared commitment to advancing sustainability through innovation. The initiative complements Tata Motors' broader sustainability agenda, which includes electric vehicles, CNG platforms, and energy-efficient mobility solutions. It aligns with Castrol India's strategy to embed recycled materials in high-performance lubricant products.

Mr. Vikram Agrawal, Head–Spares and Non-Vehicle Business, Tata Motors Commercial Vehicles, emphasised the environmental significance of the partnership. He stated that responsible used-oil management is central to building a circular automotive ecosystem in India.

Mr. Anoop Jindal, Vice President–B2B (OEM) Sales, Castrol India Limited, highlighted that creating a circular economy for lubricants requires collaboration across the entire value chain.
