PROBLEM TO BE SOLVED: To provide a method of recovering resource from a disposed communication cable coated with gel without generating pollution. SOLUTION: This method of recovering resource from a disposed communication cable recovers copper wire chips and polyethylene resin chips from a disposed communication cable containing gel. This method is formed of a process for cutting the disposed communication cable to separate it with a tube cutting device 1, a process for compressing the cable with a compressing roller 2 to separate the gel, a process for cutting the cable at the predetermined length with a coated copper wire cutting device 3, a process for crushing with a primary crushing device 4, a process for washing with a primary specific gravity separating device 5 and a vibration separating device 6 to separate foreign materials, a process for crushing again with a secondary crushing device 7, a process for separating the copper wire chips from the polyethylene resin chips with a secondary specific gravity device 8, a process for drying the copper wire chips with a copper wire chip drying device 9, a process for dehydrating the polyethylene resin chip with a vibration dehydrating device 10.
