In order to determine the energy consumption (electricalenergy consumed per kg. of fiber) during the electrochemical recycling process, I4 group was taken as an example.When the current was 4 mA, the feeding voltage across CFRP, NaCl solution, and steel was measured to be around 2.6 V during the whole process (actually, the voltage across CFRP was not more than 2.6 V). Thus, the electric charge passing through the CFRP during 21 days is not more than
