Identification of plastic material composition

摘要

Identification of a material composition. The material composition is configured with a color additive that is embedded or otherwise not visible. The color additive identifies the specific material composition. A discrete section or sub-section of the material is deformed such that the embedded color additive is made visible in the optical spectrum, after which the discrete section or sub-section may be sorted for recycling.

主权项

1. A system comprising:
a platform to carry a body comprising a first material and a second material, the first material having a first property and the second material in communication with the first material having a second property, the second property different from the first property, and the second property of the second material non-visible to an optical wavelength in a first state of the body; an applicator in communication with the platform, the applicator to deform the body beyond a deformation range, including the applicator to transform the body to a second state different from the first state; and a scanning module in communication with the platform, the scanning module to identify a characteristic of the second material made visible to at least one optical wavelength in the second state, the visible characteristic of the second material to identify a composition of the body.
