The production of carbon fiber is increasing steadily, however, the material that needs to be recycled is still a challenge. According to a research conducted at Washington State University, it is possible to grind up carbon fiber waste and use it in improving the pervious concrete. Pervious concrete is highly-porous and can handle stormwater run-off making it pass straight through into the soil underneath. It prevents flooding and also reduces pollution run-off to the aquatic life. The traditional non-pervious concrete makes the water run the length of the road and accumulates more and more pollutants along the way.
In addition to that, since the carbon fiber is added to the mixture in cured and composite form, neither heat nor any chemicals are required to process it. The researchers have demonstrated the effectiveness of the technology on some laboratory samples. They are also looking forward to conducting large-scale tests soon enough.
