Imerys and Seitiss announce the creation of a Joint Venture to develop mineral solutions from the circular economy

  • Imerys and Seitiss are joining forces in a Joint Venture: Seitiss Imerys Minéraux Circulaires, to provide a circular economy offer that allows the utilization of waste minerals from various industrial activities.
  • Seitiss creates and operates innovative and high value-added circular value chains, using unique digital tools to locate untapped sources of waste and create value chains to turn them into circular products.
  • Imerys brings its industrial and commercial expertise and know-how, as well as its international deployment capabilities.

Imerys invests in innovative circular economy solutions

This Joint Venture with Seitiss illustrates the growing need for manufacturers to better recover waste produced through industrial activities. Olivier de Mougins, Group Strategy Vice President at Imerys: “Thanks to this partnership with Seitiss, Imerys wishes to enrich its offering of circular solutions to meet the growing expectations of its customers in terms of recycled minerals. This is a new step taken by Imerys towards a greater circularity of its resources. Seitiss Imerys Minéraux Circulaires will be able to recover a growing number of industrial waste in many areas."

The joint venture will use innovative tools developed by Seitiss, making it possible to source unexploited waste deposits and promote them to various industrial users, including Imerys.

Towards the development of circular economy sectors

2.3 billion tonnes of waste is generated each year around the world, with a significant part coming from industrial activities, and more than half being buried or incinerated. Waste of industrial origin therefore represents a major problem which leads to the degradation of natural environments, the occupation of spaces, and the release of pollutants. All this waste represents significant and unexploited deposits which would make it possible to reduce the extraction of natural resources. 

For Jean-Baptiste Quintana, CEO of Seitiss & future President of Seitiss Imerys Minéraux Circulaires: "Imerys' investment in Seitiss Imerys Minéraux Circulaires will accelerate the development of numerous circular economy value chains involving a wide variety of resources. We are very excited and delighted to join forces with a renowned industrial partner, whose experience in running large-scale industrial operations will be beneficial and enable great strides to be made to improve the circular economy of mineral waste."

Financial and operational support

In addition to its financial investment, Imerys will provide Seitiss Imerys Minéraux Circulaires with industrial and commercial know-how as well as its international presence to accelerate the development of the first identified opportunity relating to the valorization of recycled calcium carbonate from industry. “This Joint Venture will benefit from Imerys’ technical expertise and capacity for innovation in order to offer customers high-performance mineral products with minimal impact on the planet,” says Frédéric Jouffret, Vice President Science & Technology, Performance Minerals.
