The process retains properties of fibers at a higher rate than previous methods, demonstrating a retention strength of up to 90 percent. Recycling of composite materials could be up to 70 percent cheaper and lead to a 90-95 percent reduction in CO2 emissions compared to standard manufacturing.

This is the case with carbon fibre reinforced polymer (CFRP) composites, non-biodegradable materials which, until now, have lacked a viable recycling method.

CRFP composites are present in products such as wind turbines, aeroplane parts, vehicles such as cars and ships, and everyday technology such as laptops and mobile phones.

They are typically disposed of in landfills or by incineration, which pose significant threats to both the environment and public health.

The vast majority of existing recycling methods also cause a major reduction in the mechanical and physical properties of the recovered material, weakening its core functionality.

Researchers from the University of Sydney’s School of Civil Engineering have developed an optimised method for recycling CFRP composites while maintaining 90 percent of their original strength.
