When designing high performance products, LEM is committed to respect the environment and the principles of sustainable development. A step further is the concept of Eco-Design.

This approach consists in designing products while limiting their maximum impact on the environment such as:

• human health and safety,

• natural resources: consumption of raw materials and energy,

• ecosystem conservation: pollution of water, soil and air, climate change.

Eco-design Product lifecycle

When using this approach, the whole product lifecycle is taken into account from its early design to its end of life at the moment of its recycling. It is a well-known fact that the design decisions for a product will condition its abilities to impact the environment.

For each step of the product lifecycle, an analysis is performed to keep the design solutions which will contribute to a sustainable environment, by reducing its environment impact as much as possible.

The three stages of the product lifecycle that are screened include:

Design Use End of Life

For each of these stages, LEM has defined rules to respect in order to achieve this main environmental goal:

To design a product with as little impact on the environment as possible throughout its life!
