Facilities for Material-Specific Sorting and

The problem
The countless synthetic packings are a great challenge for refuse 
disposal. In Germany, for example, recycling of synthetic packings is 
laid down legally. Until now, sorting -as a part of this process- was 
time-consuming and caused enormous costs because the sorting out of 
synthetic packings was mainly done manually.
Neural network application
A system of sensors registers  the individual objects. The follow-up 
software, based on neural network technology, decides to which class of 
material the registered object belongs and provides the facilities for 
sorting with this information.
Benefits
The application of neural networks replaces the costly manual sorting 
process by an automatically-driven system, even avoiding direct contact 
with the objects. Furthermore, supplementing the system with a sensor 
for color-detection allows for the extraction of high-quality synthetic 
material of pure sort and color.
Generalization
This application illustrates the growing importance of neural network 
technology for environmental protection.
