Assessing environmentally friendly recycling methods for composite bodies of railway rolling stock using life-cycle analysis
Carbon fiber reinforced plastic is applied to railway car bodies to lighten them and reduce fuel consumption. This study looks at recycling methods for carbon fiber reinforced plastic used in a car body of a tilting train. It looks at four types of recycling: acid, pyrolysis in oxygen and nitrogen, organic solvents and supercritical process under various operating conditions. It evaluates the environmental performance of the recycling methods in terms of footprints of energy consumption and greenhouse gas emissions. A simplified life-cycle analysis is applied focusing mainly on the recycling treatment system. Only acid and pyrolysis in oxygen were capable of passing the technical and recyclate quality criteria. The energy footprint by pyrolysis in oxygen is approximately six times greater than acids and greenhouse gas emissions are some five times greater than with the acid recycling method.
