Deliverables

Summary: The design for the presorter was based on the spectroscopical observation that plastics show characteristics reflectance peaks in the optical near infrared reflectance (NIR) wavelength region. Typical nonplastics such as metals, wood, paper, ceramics and glass show less characteristical spectral patterns. A presorter has been designed under laboratory conditions. An infrared camera watches via an infrared mirror and monochromator, a single illuminated waste sample. A sequence of digital infrared images on several typical wave length is taken from this object and read into a computer workstation. This data is preprocessed and combined image processing and classification is applied in order to identify the class and size of each object. This data can be used for further processing / sorting of the waste stream.
