A long-term industrial platform

The resource that anchors everything
Our operations are anchored in high-purity chemical-grade limestone resources, representing approximately 17.84%* of India’s chemical-grade limestone base and enabling forward integration across mining, processing, and lime production. For our customers, this is not a statistic, it is supply confidence.
Scale ensures:
- Long-term contract security
- Stable process planning
- Consistent chemical input
- Reduced exposure to raw material volatility

In gratitude

Among the people who shaped our understanding of lime, Mr. Hiroo Makhijani holds a special place. We came to him as newcomers — without introduction, without connection, and with nothing to offer. Yet he shared the full breadth of knowledge without hesitation. That generosity, so rare in any field, is something we have never forgotten — and his quiet clarity and deep experience left a lasting impression on how we look at materials and processes.
He often reminded us that "Lime making is more of an art than pure science" — and over time, we came to understand exactly what he meant. The philosophy behind Dr Lime owes much to his wisdom and generous spirit.
