Business News | Green cement is a concrete step towards building a sustainable India
New Delhi [India], March 31 (ANI/Mediawire): The Indian government is focusing heavily on infrastructure development in the country to boost economic growth. With the pandemic and subsequent lockdowns setting back growth for years, work on housing, transport infrastructure and electricity is back in full force. Due to the use of cement in such endeavors, India is only second to China as the largest cement producer in the world.
Since the pandemic, India and the world are pushing harder than ever to achieve climate goals. Moreover, for India, the need and importance of reducing emissions is twofold; target climate change and reduce current dangerous levels of air pollution. However, it is also a fact that cement, a key component of concrete, is a major contributor to CO2 emissions. Studies show that the cement industry’s annual global production of 4.2 billion tonnes contributes about 7% of global annual carbon dioxide emissions.

The use and demand for cement will only increase due to population growth and the need for housing and infrastructure. India, like the rest of the world, must accelerate the journey to zero carbon. In the cement industry, emission problems in the manufacture of cement. The energy used to heat the kilns that produce the clinker and the chemical processes that convert limestone into calcium oxide are the main causes of these emissions. However, the Indian cement sector has been at the forefront of the response to climate change. Many large cement companies have achieved huge emission reductions by using additional cementitious materials, improving energy efficiency, replacing fossil fuels with alternative fuels, using waste heat to generate electricity and by scientifically testing new production techniques and process improvements.
Technologies such as waste heat recovery (WHR) power generation systems, reducing or ceasing the use of fossil fuels, utilizing solar energy, as well as converting current fossil fuel-based facilities to units based on renewable biofuel, are used by various companies to reduce emissions during the production of cement. As the need for energy is paramount in the cement industry, the solution to its emissions problems lies in finding renewable electricity that can produce clean, safe, affordable and endless energy. All over the world and in India, companies are changing their manufacturing techniques to switch to clean energy and reduce their carbon footprint.

JSW Cement uses blast furnace slag, a by-product that is produced during the ironmaking process at integrated steel mills to produce low-carbon green cement. Highly effective in chemical resistance, slag increases the durability and late strength of concrete. Slag cement can replace 70-80% of OPC in various grades of concrete mixes, while it can be used 100% in massive concrete projects and other industrial structures.
Three of JSW’s products – Portland Slag Cement (PSC), Composite Cement (CC), and Ground Granulated Blast Furnace Slag (GGBS) – are GreenPro Certified and made JSW Cement the first cement manufacturer in the nation to receive the eminent certification. GreenPro for Portland. Slag Cement (PSC) from the CII-IGBC (Confederation of Indian Industry – Indian Green Building Council). JSW has also required EPDs for its PSC and GGBS products which help achieve USGBC certification.
JSW Cement initiatives that have received GreenPro certification include CO2 emissions reduction, use of alternative raw materials, improved mine life, limestone conservation, efficient water management, mine restoration, green belt development and biodiversity. In accordance with JSW’s PSC Product Life Cycle Assessment and EPD Certification, JSW PSC has been conclusively proven to have less environmental footprint than OPC in parameters such as lower global warming potential climate, maximum use of secondary materials, less potential for acidification and eutrophication and minimum consumption of non-renewable primary energy.
From a consumer and contractor perspective, switching to green cement is the best way to help reduce the carbon footprint. Green cement is basically cement produced by companies through various manufacturing techniques that reduce carbon emissions. Compared to OPC, green cement consumes about 60% less thermal energy and the carbon emission intensity of green cement is also 60% lower.
According to market forecast, the green cement market was recorded at US$609.3 million in 2019 and is expected to cross US$678.2 billion by 2026. Between 2020-2026, the market is expected to recording a CAGR of 4.8 per cent.
The governments of the United Kingdom (UK), India, Germany, United Arab Emirates and Canada, under the new Industrial Deep Decarbonisation Initiative (IDDI), announced a commitment in November 2021 which sends a clear message to heavy industry – “If you make low carbon steel and concrete, we will buy it”.
The group of countries announced plans to buy low-carbon steel and concrete at the UN Climate Change Conference in Glasgow, with specific interim targets by 2030 expected to be revealed at the next Clean Energy Ministerial (CEM) meeting by mid-2022. . At present, government steel and cement procurement in the five countries accounts for 25-40% of the domestic market for these materials.
While the cement industry is trying to reach Net Zero with green cement, this relatively new product holds negligible overall market share in India. Among the many challenges to make it a dominant product, awareness and cost to the consumer top the list. These two challenges are also symbiotic in the sense that improving consumer awareness will increase demand and therefore increase its production, leading to a better price for the consumer.
Being the second largest cement producer in the world, India’s global share in cement is about 9%. This means that a shift in consumer preferences in India would significantly affect the global war on climate change. Government can really drive change in commercial structures and individual housing by mandating a minimum component of green cement while emphasizing investment.
India is already among the best countries in the world trying to create a sustainable future with clean energy. The manufacture and use of green cement can significantly boost the cement industry’s efforts towards a greener and cleaner future.
All of our marketing efforts are aimed at getting the message across and the importance of using green and sustainable products, as demonstrated by our national TVCs and other efforts. It is surprising to many that cement can also be green and sustainable. Gurminder Singh, Head – Branding
“JSW Cement has a disruptive business model in the building materials business. Although we face headwinds and resistance in selling innovative low-carbon products, JSW management is committed to promote its range of sustainable products for the greater good of the people of India. We are hopeful that in the near future government procurement will embrace low-carbon products and lead by example.” Manoj Rustagi – EVP – Sustainability & Innovation, Capex Projects.
