Best solutions for your business

We aim to provide the exact qualities you need for your business: automated, reliable, safe and energy-efficient quarries and treatment facilities. Our kilns are carefully selected in line with each process and we use the most energy-efficient fuels for them. One of our goals is to limit waste, which is why we continuously strive to optimize our consumption of raw materials to achieve this. 

Sustainable practices for the future

In our fast-changing and increasingly regulated world, Lhoist’s R&D department focuses specifically on ways to address environmental challenges. We are committed to developing sustainable solutions in response to vital environmental issues, particularly in the areas of water and gas treatment, agriculture and the steel industry. Our experienced research centers provide a platform for training and technical development for sales and production resources. They also serve as laboratories for pilot projects and trials. These can be implemented both in Lhoist’s plants and at your facilities. 

Continous innovation

We constantly strive to improve existing products and design new concepts. This is achieved through close cooperation with customers and experts. 

Our solutions are already present in your daily life. To assure a better future, Lhoist conducts continuous research to increase the benefits that our products provide. At our pilot plant facilities, researchers simulate new methodologies to show how we can reinforce the expansion and enhancement of your product portfolios. 

More than one thousand different types of limestone, dolomite and other minerals have already been discovered around the world. We use our extensive background and scientific knowledge to adapt their properties and transform them into new and innovative industrial products.  

An expanding business

Our emphasis has always been on the search for new markets, the co-development of innovative applications, and the launch of products and services that enhance customer satisfaction. This is especially true in the domains of steel, the environment, civil engineering and agriculture. We undertake applied research throughout the group. These efforts draw on collaborative partnerships with customers, renowned academics, research institutions, international experts and private partnerships. They require extensive financial and human resources and allow us to develop original concepts for clients in various industries. Our actions also enable us to enter previously untapped markets for future applications to help make lives increasingly more comfortable. 

We place significant emphasis on the development of truly sustainable products, processes and services to meet our clients’ needs and support our organic growth.
