INSEE drives sustainability through its ‘Sustainability Ambition 2030.’ A strategic framework built on three strategic pillars, such as Climate & Energy, Biodiversity & Water, Circular Economy, and two interconnected themes of Community & Stakeholder Engagement, and Occupational Health & Safety, all of which pave the way for a resilient and responsible future. From restoring quarries to thriving ecosystems, reducing water consumption across operations, and replacing fossil fuels with alternative waste-derived energy sources, sustainability is a core operational principle. INSEE Ecocycle, the company’s waste management arm, further strengthens the circular economy model, offering sustainable industrial waste solutions, reducing environmental impact, and promoting resource efficiency.
INSEE Cement steers the local building and construction industry towards low-carbon, environmentally responsible projects, introducing consistently high-quality, superior blended cement products and sustainable building materials through substantial investment in innovation and R&D.
Its flagship brand, INSEE Sanstha Cement, has evolved from Ordinary Portland Cement (OPC) to becomethe first to introduce Blended Cement in Sri Lanka, significantly reducing CO₂ emissions and preserving valuable natural resources through reduced clinker content and industrial byproduct integration. As the first brand to introduce environmentally friendly Portland Composite Cement (PCC) (SLS 1697:2021) to the Sri Lankan market, INSEE Sanstha catalyzed a national shift towards more environmentally responsible building materials.
