Document Type and Number:
WIPO Patent Application WO/2021/181533
Kind Code:
A1
Abstract:
Provided is a biodegradable-resin decomposition device with which a decomposition product of stable quality can be obtained even when the feed material fluctuates in property. The biodegradable-resin decomposition device (1) is a device in which a biodegradable resin having ester bonds is kneaded together with an additive to decompose the biodegradable resin, and comprises a reactor (11) into which the biodegradable resin and the additive are introduced, a screw (12) which kneads the contents of the reactor (11), a heater (13) which heats the reactor (11), a viscometer (152) with which the viscosity of a decomposition product is measured, and a controller (40) which controls the screw (12) and/or the heater (13) on the basis of the viscosity measured with the viscometer (152).
