A degradation device (100). The degradation device (100) comprises a container (101), a nozzle (102), a first pipeline (103), and a water pump (104). The container (101) is used for containing a material to be degraded. The nozzle (102) is disposed on a side wall of the container (101), and the nozzle (102) ejects into the container (101) and is used for spraying a solvent to the material to be degraded. One end of the first pipeline (103) communicates with the nozzle (102). A water outlet end of the water pump (104) communicates with the other end of the first pipeline (103). The water pump (104) is used for providing an ejection pressure to the nozzle (102). In the degradation device (100), a material to be degraded is placed in the container (101), and the water pump (104) provides an ejection pressure, so that the nozzle (102) can spray a solvent to the material to be degraded in the container (101); the solvent stirs the material to be degraded under the action of the pressure, so that the material to be degraded can be in full contact with the solvent and is degraded in an accelerated manner. The material to be degraded may be foamed plastics. The degradation device (100) has a simple structure and low costs, can be widely used, and helps to resolve the environmental problem brought by foamed plastics and other consumables that are difficult to degrade in nature degradation.
