Advanced composite technology reduces laptop’s carbon footprint

In Germany, a recent Life Cycle Assessment (LCA) found a laptop cover made of Maezio continuous fiber-reinforced thermoplastic composites from Covestro can significantly reduce the carbon footprint by more than 70 percent compared to one made from conventional aluminum-magnesium alloy.

Maezio composites are based on continuous carbon or glass fibers impregnated with polycarbonate, thermoplastic polyurethane (TPU) or other thermoplastic resins.

The LCA study, conducted in line with ISO 14040/14044 standards and reviewed by an independent panel of LCA experts chaired by DEKRA Assurance Service GmbH, compared a comprehensive range of parameters to assess the environmental performance of a laptop A-cover made from the two materials which are typically used for premium laptops. In all impact categories and scenarios, the composite laptop A cover shows better environmental performance than the aluminum-magnesium alloy cover from the extraction of raw materials until the end of life. 

Even after the implementation of current technology developments – use of low impact cover gas for aluminum-magnesium alloy and potential benefits of recycling for both materials – the composite carbon footprint is still more than 30 percent lower.
