Nuvoco Vistas Corp. Ltd reported a strong financial performance for the quarter ended 31 December 2025 (Q3 FY26), driven by record cement sales, higher premium product volumes and improved operational efficiencies.

The company achieved its highest-ever third-quarter consolidated cement sales volume of 5 million tonnes, registering growth of 7 per cent year-on-year. Consolidated revenue from operations rose 12 per cent to Rs 27.01 billion during the quarter. EBITDA increased sharply by 50 per cent YoY to Rs 3.86 billion, supported by improved pricing and cost management.

Premium products continued to be a key growth driver, sustaining a historic high contribution of 44 per cent for the second consecutive quarter. The strong momentum reflects rising brand traction for the Nuvoco Concreto and Nuvoco Duraguard ranges, which are increasingly recognised as trusted choices in building materials.

In the ready-mix concrete segment, Nuvoco witnessed healthy demand traction across its Concreto product portfolio. The company launched Concreto Tri Shield, a specialised offering delivering three-layer durability and a 50 per cent increase in structural lifespan.

Leading industry bodies, including the Global Cement and Concrete Association (GCCA), European Composites Industry Association, International Solid Waste Association – Africa, Mission Possible Partnership and the Global Waste-to-Energy Research and Technology Council, have issued a joint statement highlighting the cement industry’s potential role in addressing the growing global challenge of non-recyclable and non-reusable waste. The organisations have called for stronger policy support to unlock the full potential of cement industry co-processing as a safe, effective and sustainable waste management solution.

Co-processing enables both energy recovery and material recycling by using suitable waste to replace fossil fuels in cement kilns, while simultaneously recycling residual ash into the cement itself. This integrated approach delivers a zero-waste solution, reduces landfill dependence and complements conventional recycling by addressing waste streams that cannot be recycled or are contaminated.

Already recognised across regions including Europe, India, Latin America and North America, co-processing operates under strict regulatory and technical frameworks to ensure high standards of safety, emissions control and transparency.

Commenting on the initiative, Thomas Guillot, Chief Executive of the GCCA, said co-processing offers a circular, community-friendly waste solution but requires effective regulatory frameworks and supportive public policy to scale further. He noted that while some cement kilns already substitute over 90 per cent of their fuel with waste, many regions still lack established practices.

The joint statement urges governments and institutions to formally recognise co-processing within waste policy frameworks, support waste collection and pre-treatment, streamline permitting, count recycled material towards national recycling targets, and provide fiscal incentives that reflect environmental benefits. It also calls for stronger public–private partnerships and international knowledge sharing.

With global waste generation estimated at over 11 billion tonnes annually and uncontrolled municipal waste projected to rise sharply by 2050, the signatories believe co-processing represents a practical and scalable response. With appropriate policy backing, it can help divert waste from landfills, reduce fossil fuel use in cement manufacturing and transform waste into a valuable societal resource.
