Creating a closed-loop economy

Plastics recycling is an area where the benefits of using optical sorting technology are readily apparent.
Sorting regrind or otherwise fragmented plastic using an optical sorter enables the automation of the recycling process, significantly increasing efficiency and effectively reducing the costs of separating plastics into individual color fractions, thus increasing the percentage of recycled plastics.
In the case of mixed waste recycling, an optical sorter works seamlessly with complementary technologies such as flotation and electrostatic sorting.

Expand the range of applications

  • Color sorting is one of the stages of the recycling process, allowing to expand the range of applications and increase the cost of the regranulate obtained later. It is also great for internal recycling of production waste.
  • SmartSort sorters are used in the recycling of waste electrical and electronic equipment (WEEE) and end-of-life vehicles (ELV), thanks to the cooperation of color cameras and InGaAs cameras, which, working together, are able, for example, to detect rubber contamination in black plastic and support the removal of other foreign bodies.

The highest precision of plastic cleaning

Cloud color cameras in cooperation with energy-saving LED strips and backgrounds of various colors to increase contrast make SmartSort sorters ideal devices even for sorting transparent materials such as PET flakes.

  • SmartSort sorter software allows not only the detection of assortment defects manifested by a difference in color or shade but also the removal of impurities of a different shape and size.
  • InGaAs near-infrared cameras and UV cameras allow for multispectral analysis of the sorted regrind, supplementing the capabilities of our devices with the detection of flakes indistinguishable by color.

Recycling and more

Optical color sorting is not the only application for an optical sorter. They can also find application after the regranulation process as well as in the production of virgin granulate, searching for and removing discolorations, inclusions, and other defects.

Cloud cameras, on which the visual recognition technology of SmartSort sorters is based, thanks to the technological advantage of resolution, are able to recognize defects sometimes arising in granulation processes, even if they differ from correctly formed particles by just a spot in a different shade.

Failure-free and even operation

A well-thought-out device layout, efficient feeding system, and auxiliary elements for controlling material flow ensure optimal and repeatable efficiency regardless of the difficulties characteristic of the caliber, elasticity, and frictional properties of a given granulate or regrind.
Work in difficult dust conditions is facilitated by the automatic operation of brushes and wipers in the detection zone and the internal architecture of the devices designed for the installation of aspiration systems.
A set of air filters mounted on each device extends the life cycle of the device, primarily protecting the valves ejecting defective material against the potential presence of water, oil, or dust in the installation.

Savings on energy and servicing

SmartSort optical sorters consume small amounts of electricity, especially since many of them operate on a low-voltage network.
Compressed air demand in our devices has also been optimized, enabling cooperation with smaller compressors.
The wear period of consumable parts before any replacement with correct use is from half a year to two years.
