Cement sector must innovate to achieve net-zero emissions

Cement production accounts for 7-8 per cent of global greenhouse gas emissions, making the sector a key focus area for sustainability efforts and highlighting the need for innovation to achieve net-zero goals, an official said. “Cement consumption in India stands at approximately 250 kg per capita, far below the global average of 500 kg. With

New research shows how biofuels affect cement production

The production of cement and quicklime is energy demanding and causes high carbon dioxide emissions. This is because the fuel, which is used for heating, and the limestone, which is converted into quicklime at high temperatures, emits carbon dioxide. By replacing fossil fuels with renewable ones, emissions can be reduced by up to 40%. The

ONGC launches four new eco-friendly cementing units

ONGC has launched four new advanced cementing units in Ahmedabad, aiming for better technology and environmental sustainability. Cementing is the process of securing a casing cylinder with cement after it is placed in an oil well. These new cementing units feature cutting-edge technology to improve performance, quality, and environmental standards. Their automation capabilities, including automatic

UltraTech Cement targets to achieve 85% green energy

The company said that it aims to meet its entire electricity requirement through renewable sources by 2050, as part of its RE100 commitment. Additionally, as a member of EP100, the company seeks to double its energy productivity. UltraTech Cement on December 13 announced its plan to significantly increase the share of green energy in its

New cement mixed with biochar absorbs more CO2

Engineers at Washington State University (WSU) have developed a new method for making concrete that absorbs more carbon than it emits. The process of making cement requires very high temperatures, and that usually requires burning fuels which, of course, emits CO2. That can be partly offset by switching to renewable energy sources, but chemical reactions

Green Planet Logistics to use LNG for cement transport

The deployment of its vehicles to UltraTech Cement’s bulk terminal in Pune has been announced by Green Planet Logistics, India’s first heavy trucking logistics company to use LNG fuel. With this second deployment of GreenLine’s LNG-powered fleet of trucks, following the initial deployment at its Awarpur Cement Plant near Nagpur, UltraTech is making progress in

First netzero cement production trial begins

The process developed at Cambridge University combines scrap steel recycling with cement clinker production using recycled concrete as a flux rather than limestone. Over the planned two-year trial period the Cement 2 Zero project will investigate both the technical and commercial aspects of upscaling Cambridge Electric Cement production to produce 20 tonnes of the world’s

At COP 27 India, China, Brazil, South Africa oppose tax on cement and steel

The European Union has proposed a policy to tax products such as cement and steel, that are extremely carbon intensive, with effect from 2026. With the 27 th edition of the Conference of Parties (COP) in Sharm El Sheikh nearing its final stages and efforts being ramped up to arrive at a conclusive agreement, a

Carbon trading market likely in India

As part of its efforts to hasten the transition to cleaner fuels, India is likely to introduce a carbon trading market for major emitters in the energy, steel and cement industries. The platform is expected to be announced by Prime Minister Narendra Modi at Independence Day celebrations on August 15. The market would initially be
