  • As part of India’s ambitious net-zero emissions goal by 2070, the country is prioritizing energy and climate change mitigation schemes. The construction industry, which accounts for around 20% of India’s annual carbon emissions, is a key area of focus. The adoption of sustainable and alternative construction materials can significantly reduce carbon emissions​.
  • Alternative construction materials such as geosynthetics (including geocomposites, geogrids, bio materials, geo mattresses) can reduce carbon emissions by up to 50%, decrease waste, use less energy, and enhance efficiencies at building sites. Advanced technologies are now enabling the construction of sustainable structures using these materials.
  • A crucial strategy is identifying, prioritizing, and applying local solutions for local problems. Utilizing local materials for construction reduces costs, saves time and energy in transporting materials, prevents wastage, and lowers the carbon footprint. These materials also help develop structures that can withstand the local weather conditions, reducing the maintenance cost significantly​.
  • A case in point is the Udhampur-Srinagar-Baramulla Railway Link (USBRL) connectivity Project. Here, alternative materials like tunnel muck, a byproduct of tunnel excavation, was used in place of concrete. This innovation reduced carbon emissions by up to 80% and cut project costs by 30%​​.
  • Companies such as Maccaferri Environmental Solutions Private Limited (MESPL) have been providing sustainable solutions for construction projects in India. MESPL provides customized solutions to the Indian Railways, the Ministry of Road Transport and Highways, the Indian Army, and several private companies. Their solutions primarily involve using polymeric products in soil or slopes for functions like drainage, filtration, separation, and strong reinforcement.
