A recent Life Cycle Assessment (LCA) has found Covestro’s continuous fiber-reinforced thermoplastic composites under the Maezio brand can significantly reduce carbon footprint compared to aluminum-magnesium alloy for laptop applications.

Covestro won second place in the “Best Lightweight Innovation” category for its composite “A-cover” for next-generation laptops.

The electronics industry is facing an increasing demand for sustainable solutions to reduce the environmental impact from the manufacture, use and disposal of electronic devices. Covestro embraces the growing need for sustainable material solutions and its new thermoplastic composite technology has proved to be a sustainable way of producing thinner, lighter and stronger components for electronic products.

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

Better environmental performance across all impact categories
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.

Lisa Ketelsen, new head of the thermoplastic composites business at Covestro says:

“Thermoplastic composites are ideally suited for producing thinner, lighter and more robust parts for IT devices that meet the needs of tomorrow. The fact that Maezio thermoplastics are not only mechanically competitive but can also be environmentally advantageous will provide the electronics industry and many other industries with a powerful solution for reducing carbon footprint and reaching their sustainability targets.”

Compared to aluminum-magnesium alloys, Maezio composites can also achieve weight reductions of approximately 15 percent, and the composite A cover exhibits a similar good bending and torsional rigidity compared to the metallic material. Moreover, the composite A cover meets the V-0 classification of Underwriters Laboratories’ UL 94 flammability standard.

Previously Covestro received a European Plastics Innovation Award for its composite “A-cover” for next-generation laptops in 2017. The development received the second prize in the “Best Lightweight Innovation” category.
