US: Environmental groups have welcomed the imminent start of work to rehabilitate Heidelberg Materials’ former Permanente cement plant and quarry in California, which ceased operations in 2023. The project, to start on 29 July 2025, will clean up a polluted section of the Permanente Creek, which flows from the Santa Cruz Mountains past the quarry site an into the San Francisco Bay.

The work was required as part of the settlement to a lawsuit filed in 2011 by the Sierra Club against Lehigh Southwest Cement company, which was subsequently acquired by Heidelberg Materials. Under the settlement, the company is required to restore 2.7km of the creek by 2030. The restoration will remove sediment that contains selenium, nickel and other heavy metals that have washed out of the quarry over the years. Workers also will plant native vegetation, build pools for trout, and stabilise slopes. The project's cost is estimated at US$25m, according to Heidelberg Materials’ David Perkins.

Environmental groups have said the work is overdue. "We're relieved that it's finally actually happening," said Katja Irvin, Guadalupe Group chair of the Sierra Club's Loma Prieta Chapter, based in Palo Alto. "There is mining waste in the creek, and concrete barriers in the creek. The slopes have been eroded. All of those problems eventually will be fixed.”

India: Tamil Nadu Cement Corporation plans to rehabilitate limestone mines which serve its 500,000t/yr Ariyalur cement plant in Tamil Nadu. The state's Minister for Industry Thalikottai Rasuthevar Baalu Rajaa said that the state-owned producer will plant saplings to start the restoration.

The Hindu newspaper has reported that Rajaa and other ministers of the Tamil Nadu government visited the Ariyalur cement plant on 25 June 2023.

Europe: The European cement industry association, Cembureau, has welcomed the enactment of the Nature Restoration Law, which aims to restore ecosystems through binding targets in line with the EU Biodiversity Strategy. The European Commission says that the law provides a framework to 'secure the things nature does for free, like cleaning our water and air, pollinating crops and protecting us from floods,' as well as to help limit climate change to +1.5°C.

In a joint statement with other extractive industry bodies, Cembureau told the EU that member states' national restoration plans should take into account industry efforts to plan and implement nature restoration, that member states should protect pioneer species in line with the Nature Directives Species Protection Guidelines' definition of temporary nature and that restoration efforts outside of designated Natura 2000 areas should be addressed on a case-by-case basis in recognition of sectoral specificities.

Portugal: Setúbal District Council has submitted its opinion in the on-going consultation process over Secil's plans to expand its Arrábida quarry in Arrábida National Park. The quarry serves Secil's Outão cement plant. The Jornal de Negócios newspaper has reported that Secil has applied to expand the quarry up to a total area of 117 hectares, and says that the newly expanded quarry would have less impact on the landscape and environment than it currently does.

Setúbal District Council acknowledged Secil's 'clear effort' in its rehabilitation of exhausted sections of the Arrábida quarry, as well as the company's importance to the regional and national economy. Nonetheless, it concluded that the proposed expansion 'is not compatible with the territorial management instruments in force, which are currently under revision.'
