Assessing Directions for Reducing Energy and Carbon Intensity of Manufacturing Large-Format Ceramic Stones

Abstract

The article analyses the experience of enhancing energy efficiency and reducing greenhouse gas emissions in the ceramic production. Calculations and assessments are made using the example of the industrial site of Wienerberger Brick LLC, located in the Vladimir region, where large-format ceramic stones are produced. Authors emphasize that ceramic production is a branch of energy and carbon intensive industrial sectors, for which in various countries and regions, programmes and projects aimed at reducing energy consumption and emissions of greenhouse gases are developed and implemented. The article presents estimated global average data and data obtained as a result of carbon intensity benchmarking conducted within the course of reviewing of the Russian national Reference Document on Best Available Techniques “Ceramic manufacturing industry”) ITS 4-2023. Authors analyse the energy efficiency enhancement programme implemented by Wienerberger Brick LLC, and calculate energy-related emissions of greenhouse gases for 2015–2022. They demonstrate that the enterprise managed to achieve a significant reduction in energy and carbon intensity. It attained parameters that are significantly lower than the industry average, as well as the so-called indicative greenhouse gas emissions indicators established to encourage Russian enterprises to implement green projects. Authors conclude that experience described can be replicated by other companies, including those applying for government support measures for projects aimed at the implementation of Best Available Techniques, enhancement of energy efficiency and reduction of greenhouse gases emissions.
