Zusammenfassung:	The invention provides a method and a system for cracking waste rubber. The waste rubber is sequentially sent to a low-temperature thermal cracking chamber, a high-temperature thermal cracking chamberand a microwave cracking chamber which respectively have an oxygen-free or oxygen-deficient environment, wherein thermal cracking of the waste rubber in the low-temperature thermal cracking chamber is carried out in a 200-400 DEG C environment, thermal cracking in the high-temperature thermal cracking chamber is carried out in a 500-800 DEG C environment, and microwave cracking in the microwave cracking chamber is carried out in a 500-800 DEG C environment; a cracking oil gas generated in the cracking process is continuously discharged from the low-temperature thermal cracking chamber, the high-temperature thermal cracking chamber and the microwave cracking chamber; and solids generated in the cracking process are recovered. The method and the system can effectively reduce the energy consumption in the cracking p
