Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a recovery system for exhaust CO2comprising an adsorption and separation process of low concentration CO2made highly efficient by cold generation through a chemical heat pump and the combination of the cold and waste heat using low temperature exhaust gas around 100-200°C exhausted from a thermal power plant, an incineration facility or a business establishment such as a factory, and a CO2refrigerating cycle for providing multipurpose cold for producing liquefied CO2and dry ice, providing a low temperature cold source, or the like using the adsorbed and separated CO2as a refrigerant. SOLUTION: This recovery system for the exhaust CO2comprises a waste heat driven chemical heat pump 31 for generating cold from low temperature waste heat 30; temperature pressure swing adsorption (PTSA) 20 for recovering and separating the low concentration CO2included in the low temperature exhaust gas 25; and the CO2super-critical refrigerating cycle 11 driven using the recovered CO226 as the refrigerant.
