Restoration & Biodiversity

The locations of our mining operations are determined by geology. On those sites, we strive to protect biodiversity as we carry out our activities. Our mining sites and quarries are restored as operations progress, often contributing to the conservation of fauna and flora species.

Our mining and processing operations use land and natural resources. This can affect biodiversity and ecosystems throughout the lifecycle of our quarries. We ensure our mining activities are compatible with biodiversity conservation through relevant planning and restoration.

Our “Post-Mining Rehabilitation” protocol requires operations to prepare their quarries’ future and describes the restoration methods that will be applied during the site’s operating life and when it closes.

Our strategy consists of building our knowledge and understanding of the environment and, in sensitive zones, encouraging the development of biodiversity management plans. Approximately 15% of the Group’s operations are located on or near zones recognized for their interest in terms of biodiversity. In 2012, the Group began encouraging the “concerned sites” to formalize their biodiversity management approaches, and in 2013, an additional two of the “concerned sites” establish a site-specific BMP based on the newly developed internal reference mentioned above. In 2014, the Group plans to increase the BMP to 20% of the “concerned sites”.

Also in 2013, Imerys’ methodologies for biodiversity risk assessment were improved to incorporate new international trends in environmental risk assessment, as well as lessons learned from internal projects. The enhanced analysis enables Imerys to plot the proximity of its mining operations’ coordinates to the closest areas of High Biodiversity Value using Google Earth.

This new methodology is much more efficient at capturing new information on protected areas and newly acquired quarries. As of December 31, 2013, 34 out of the 115 mining operations in the Group are identified as concerned sites, near or inside an area of High Biodiversity Value.

2013 Objectives 2013 Performance
  • Biodiversity management plans at 12% of sites identified in, or adjacent to areas of High Biodiversity Value(6).
  • Achieved
2014 Objectives
  • Biodiversity management plans at 20% of sites identified in, or adjacent to areas of High Biodiversity Value

We monitor the rollout of our three-year plan for Sustainable Development through performance indicators defined by internal experts.

Consumption & Discharges

Manage properly water usage and limit waste production are part of our Sustainable Development goals.

Energy & emissions

For several years, we have implemented action programs to improve the energy efficiency of its industrial activities and reduce its greenhouse gas emissions.


Constantly improving the environmental impact of our products and processes is a priority for our R&D programs.
