GEA is supporting the sustainability strategy of Asahi India Glass Limited (AIS) with the supply of two waste heat recovery (WHR) systems. Asahi India Glass is India's leading end-to-end glass and window solutions company in both the automotive and construction sectors. AIS implementing an advanced waste heat recovery system from GEA at its two glass manufacturing units – at the greenfield float glass plant in Soniyana, Rajasthan, and at the existing installation in Roorkee, Uttarakhand to have 1.8 MWel capacity for each plant. By utilizing the waste gases from the furnace and converting the heat transferred from the waste gases into electrical energy, each plant will generate approximately 15,500 MWel per year, resulting in an annual reduction in carbon emissions of approximately 13,000 tons per plant. Another highlight of the greenfield project in the Rajasthan is, it will be utilizing 94% of required power through WHR.

Performance parameters convinced AIS
GEA waste heat recovery plants are state-of-the-art systems that utilize the waste heat generated during glass production and convert it into clean and green energy. This results in a lower environmental impact as well as greater operational efficiency and energy independence for AIS plant operations. AIS chose to partner with GEA because it needed a plant that would operate at optimal standards and performance parameters for its class. Thanks to GEA's process technology and the seamless integration of the waste heat recovery plant into AIS's existing infrastructure, ensuring optimal performance and reliability, the criteria were met.
“Our collaboration with GEA is a crucial step towards our goal of achieving carbon neutrality.”
Mr. Rupinder Shelly, COO Architectural Glass, Asahi India, said, “As a leading and responsible glass company, AIS is committed to aligning state-of-the-art technologies and operations with sustainability at our new greenfield float glass plant in Soniyana. Our collaboration with GEA is a crucial step towards our goal of achieving carbon neutrality. AIS' vision on sustainability not only underlines our commitment to the circular economy, but also sets new standards in the glass industry in terms of environmental responsibility and innovation.”
Background Information
Waste Heat Recovery
Waste heat recovery is a key factor in improving overall energy efficiency. GEA technologies make it possible to capture waste heat and process gases from existing processes and reuse them for other purposes, such as heating or power generation. Saving energy and reducing emissions are key success factors in the cement, glass, iron and steel, non-ferrous metals and refining industries, and we are always at their side as a highly reliable designer and supplier of comprehensive energy recovery plants. Thanks to GEA's extensive experience and expertise with close cooperation with partners and carefully selected sub-suppliers, all solutions include highly efficient components and state-of-the-art technologies such as ORC (Organic Rankine Cycle) based energy recovery. Exactly what is required for efficient energy recovery and emission reduction depends on the individual industrial plant, considering the potential impact of energy recovery on the existing gas cleaning process or, in the case of new plants, its full integration.
