Sanjay Wali, National Sales, Marketing & Logistics Head, Dalmia Cement (Bharat) Ltd, discusses the in-roads the company has made in making production processes more sustainable and in making cement a greener product.

For 80 years, we followed a growth path that mirrored India’s promise and growth opportunities. Our philosophy of ‘Clean and Green is Profitable and Sustainable’ has helped us deliver on the expectations of our stakeholders, create sustained value for the larger ecosystem and show the way for responsible growth to others. Our focused product strategy has been a critical factor propelling us to the leadership position in the manufacturing of green cement.

We are the only cement manufacturer part of the UN Leadership Group on heavy industry net-zero transition. Moreover, we have been ranked #1 in the global cement sector on business readiness for low carbon economy transition by CDP in 2018. As we learn new methods to enhance sustainability, we are confident that our journey to decarbonise our business will pave the way for a carbon negative reality and at the same time inspire others to adopt the same path.

Leading the sector’s green movement

Sustainability led growth has always been our top priority. We are committed to becoming carbon negative by 2040, and for this very purpose, we created a roadmap to bring down our carbon footprint. Our carbon footprint at 492 kg CO2/ tonne of cement (specific net CO2) is one of the lowest group averages in the global cement sector. We installed 9.90 MW of solar and 21.70 MW of Waste Heat Recovery based power generation systems and plan to significantly increase solar and Waste Heat Recovery power generation to run our operations with more fossil-free electricity by the end of FY23. Through our continuous efforts and by proposing to use 100 per cent renewable energy by FY30, we are well on our way to leading the green movement within the sectors we operate in.

Responsible production and consumption

We understand that with leadership, comes responsibility. Therefore, as a leading proponent of ‘Green Cement’, we consume the waste produced by other industries and ensure that the waste produced at our facilities, both hazardous and non-hazardous is disposed-off as per legal requirements and in a responsible manner. In FY21 we utilised 7.83 million tonnes of alternative cementitious material and 0.2 MnT alternative fuels, which includes industrial wastes, for the pyro process. Both these waste categories were sourced from other companies. In comparison to this, the waste generated and disposed of by us stands at a mere 10,245 tonnes.

Our environment discipline is encapsulated in the principle of ‘Producing maximum cement with minimum harm to nature and natural resources. In FY21, we made a bold commitment to become a 100 per cent blended cement company over the next five years. Currently, our facilities in Eastern India are dedicated to producing 100 per cent blended cement and we now aim to maximise blended cement production across all our operations.

Energy efficiency and energy productivity

Cement production is an energy-intensive process, therefore, responsible use of energy is key to reducing environmental impact. We invest in low carbon technologies to reduce dependency on fossil fuels and better manage energy usage across the production value chain. Our newly commissioned plants are constantly setting industry benchmarks in the adoption and use of energy efficiency measures and our growing network of captive power plants allows us to wheel surplus power across our facilities in different parts of the country to optimise costs further.

Developing greener solutions for a better tomorrow

We are steadfast about our products causing minimal harm to the environment while delivering the highest quality. Our low porosity of Dalmia Infragreen enhances the durability of the product. It does not require any other chemical admixtures and delivers high strength, durable and waterproof concrete. It uses lesser heat in hydration than OPC large and mass concreting and can control thermal linked cracks of large sections better. Dalmia Infragreen has superior water ingress resistance and provides long-term durability against atmospheric carbonation, harmful chlorides and sulphates from groundwater usage. Our product can get runways, highway stretches and metro sections operational in three days, whether used for building, maintenance or repair.

Encouraging stakeholder partnership towards a net-zero pathway

We recognise the importance of reducing carbon emission causing global warming and are committed to climate protection to become a carbon negative cement group by 2040. We are one of the first few cement companies to commit to the Mission Possible Partnership setting science-based targets, and join the First Mover’s Coalition as founding members. Our defined ambition is to become carbon negative by 2040, beyond net-zero and well before the cement sector roadmap’s 2050 targets. We are proud to declare that as of FY21, we are already well below the current global Net Zero pathway target for the cement sector.

To foster greater adoption of this environmentally friendly building material, we have undertaken stewardship to create awareness of the product across our customers, institutional or individual. We encourage the use of blended cement and contribute to protecting our planet. Our dealers and distributors are the critical last-mile link to encourage customers to buy green cement for their building needs. Together, we will propagate the consumption of sustainable products such as our green product line to advance a negative carbon reality. Our efforts have already borne fruit as we recently became the first cement company in India to receive a green accreditation from the Green product rating for Integrated Habitat Assessment (GRIHA) council, and we were also awarded the prestigious GreenPro Ecolabelling Certificate by the Indian Green Building Council (IGBC), a part of the Confederation of Indian Industries (CII). We will continue to drive awareness and understanding of the benefits of green cement across our distribution chain.

The Department of Science and Technology (DST) recently unveiled a pioneering national initiative: five Carbon Capture and Utilisation (CCU) testbeds in the cement sector, forming a first-of-its-kind research and innovation cluster to combat industrial carbon emissions.
This is a significant step towards India’s Climate Action for fostering National Determined Contributions (NDCs) targets and to achieve net zero decarbonisation pathways for Industry Transition., towards the Government’s goal to achieve a carbon-neutral economy by 2070.
Carbon Capture Utilisation (CCU) holds significant importance in hard-to-abate sectors like Cement, Steel, Power, Oil &Natural Gas, Chemicals & Fertilizers in reducing emissions by capturing carbon dioxide from industrial processes and converting it to value add products such as synthetic fuels, Urea, Soda, Ash, chemicals, food grade CO2 or concrete aggregates. CCU provides a feasible pathway for these tough to decarbonise industries to lower their carbon footprint and move towards achieving Net Zero Goals while continuing their operations efficiently. DST has taken major strides in fostering R&D in the CCUS domain.
Concrete is vital for India’s economy and the Cement industry being one of the main hard-to-abate sectors, is committed to align with the national decarbonisation commitments. New technologies to decarbonise emission intensity of the cement sector would play a key role in achieving of national net zero targets.
Recognizing the critical need for decarbonising the Cement sector, the Energy and Sustainable Technology (CEST) Division of Department launched a unique call for mobilising Academia-Industry Consortia proposals for deployment of Carbon Capture Utilisation (CCU) in Cement Sector. This Special call envisaged to develop and deploy innovative CCU Test bed in Cement Sector with thrust on Developing CO2 capture + CO2 Utilisation integrated unit in an Industrial set up through an innovative Public Private Partnership (PPP) funding model.
As a unique initiative and one of its first kind in India, DST has approved setting up of five CCU testbeds for translational R&D, to be set up in Academia-Industry collaboration under this significant initiative of DST in PPP mode, engaging with premier research laboratories as knowledge partners and top Cement companies as the industry partner.
