Annual Report 2021

At the heart of the future for a more sustainable world

Additive manufacturing

In 2021, the first 3D-printed metal bridge was inaugurated in Amsterdam. This was a technological feat to which Air Liquide made a major contribution. The Group shared the welding and additive manufacturing expertise of its R&D teams and provided shielding gases to MX3D, the tech start-up that masterminded the project. More generally, industrial gases play a key role throughout the chain of additive manufacturing processes, ensuring their safe execution, operational stability and the final quality of the metal parts.

Alternative proteins

By 2050, the Earth will have 10 billion inhabitants, and food production will need to increase by 70%. This global challenge will mean using new sources of accessible, sustainable proteins such as plant proteins, insects or proteins derived from fermentation. Air Liquide is committed to this transition through the supply of gas and equipment solutions to those working in this field. The Group has forged R&D and industrial partnerships notably in Belgium, Canada, France and Germany, to support the development of this high-growth sector.
