US: Heidelberg Materials North America has reached an agreement with the administration of Santa Clara County to decommission its quarry in the county, near Cupertino. Silicon Valley News has reported that the quarry historically supplied limestone for cement production at Permanente cement plant, which came offline in April 2020. The county administration says that the deal signals that it has achieved its aim to ensure final closure of the Permanente plant.
Heidelberg Materials North America spokesperson Jeff Sieg said that the company is ‘pleased to formalise our agreement not to restart the kiln at our Permanente cement plant.’ He continued "We remain focused on working collaboratively with the community and other stakeholders on the development of a long-term strategy for the property, so that it can continue to provide value in the future.”
