Why They Are a 2025 Climate Leader

The energy efficiency project completed at Oldcastle Stone Products stands as the largest in Berkshire Gas’ history. This transformative initiative involved the replacement of a screen and mill within their production process, resulting in a substantial reduction in natural gas consumption during the manufacturing of limestone pellets. Thanks to the scale and impact of this upgrade, an impressive 2.9 million therms in energy savings was claimed.
