Waste & Water management

Tackling environmental pollution

In a world with growing populations and natural resources scarcity, our industrial society is challenged by competing priorities: the ongoing search for productivity and the need to tackle environmental issues. In addition to increasing output, industries must reduce their polluting emissions, improve their processes for a maximum reuse of water and materials, while complying with increasingly strict regulations.

Helping industries reduce their environmental impact

Industrial gases can offer alternative solutions to the traditional water and waste treatment processes, providing environmental benefits in competitive manners. At Air Liquide, we leverage our gas expertise and technologies to develop these solutions proactively.

The challenge of attaining maximum efficiency at reasonable costs

Our R&D and application experts are continuously designing new gas offers that will become the industry benchmark of tomorrow.

Our goal is to help customers reduce their environmental impact and to conform to the strictest of environmental legislation. To rise to the challenge of attaining maximum efficiency at reasonable costs, we work hand in hand with our customers to implement competitive gas solutions and therefore deliver results when and where it matters most.

Air Liquide experts are in the field to find the best solutions for our customers.

Mastering applications for the management of waste and water

At Air Liquide, we master applications using gas technology to treat water, recycle metal, recover solvents, analyze air quality and valorize waste.

Focused on performance, we go beyond gas and propose a full expertise for client needs. We work with our customers in the way that suits them best.

Metal recycling

The smelting industry must increase existing production capacities while minimizing its environmental footprint. To help industrial actors involved in metal recycling just do this, Air Liquide has developed BOOSTAL™, our range of oxy-combustion technologies that draw on the power of pure oxygen instead of air in burners to heat up furnaces, for superior production efficiency.

Air pollution control

Air Liquide supplies analytical gases for air quality monitoring laboratories and industries. Our ALPHAGAZ™ range of pure gases and calibration mixtures is designed specifically to run analytical equipment and ensure high accuracy in use.

Water treatment

For industries, municipalities and water utility companies, Air Liquide offers ASPAL™, a range of dedicated solutions for drinking water, cooling water and waste water treatment. ASPAL™ is the result of a longstanding collaboration with our customers to understand their challenges and specific needs.

ASPAL™ leverages our know-how in pH control, biological and activated sludge treatments, odor control and disinfection, as well as scale prevention. Our expert teams implement our solution on site to ensure the expected performance.
