Dalmia are repurposing industrial waste products, turning industry byproducts and scrap into a cement high on strength and low on environmental impact.

By substituting a percentage of cement ingredients with industry waste products, Dalmia saves natural resources and helps to reduce the environmental impacts of its industrial processes. Their blended cements include industrial waste products such as fly ash from coal-based thermal power plants and waste from the steel industry. These additives lead to reductions in limestone mining, and improvements in energy efficiency with reduced CO2 emissions from the actual manufacture of their cement. The company continues to innovate, driving up the percentage of waste products incorporated in their cements, helping to reduce more of their greenhouse gas emissions.

Why you should care

This solution addresses the resource efficiency challenge in the energy-intensive cement manufacturing industry. The challenges of natural resource depletion and climate change are pressing. This solution shows that it is possible to reduce material and carbon footprints by substituting new materials with  suitable waste materials from other industries, without affecting product quality.

How the Global Goals are addressed

Responsible Consumption and Production

Utilizing otherwise wasted resources helps to reduce demand for limestone and reduce carbon emissions in the construction sector.

Climate Action

Cement production can be an extremely carbon intensive process. Using waste products from other industrial activities can substantially lower the carbon footprint of cement production.
