Recovery of Carbon fibers from composites via flash pyrolysis
Recovery Carbon Fibers
Recovery of materials and energy is one of the pillars of a sustainable society. Carbon and glass fiber based materials are used for many products and in many forms. The recovery of carbon and glass materials is important for the industry to get green credits and to reduce costs. In this project the focus is on the recovery of carbon fibers from reinforced composite plastics, and on the recovery of glass fibers used in a wide range of different applications such as wind turbine blades, automotive applications, and boats. For both materials the problem is that the fibers are mixed with other components such as plastics, rubber or metals. Mechanical recovery from the waste streams is not successful as the resulting products do not meet the specs for reuse in high-quality products.
The goal of the present project is to recover carbon and glass fibers from waste streams via a new flash pyrolysis technology. The focus is on recovering carbon fibers from composite materials and glass fibers from polyester waste streams in an energy efficient way and to produce high-quality fibers and fuels for new applications and products.
