Regenerative Energie
Waste is a heterogeneous mixture of materials often containing reusable or recyclable materials. In accordance with the hierarchy of the EU requirements 'Prevention - Preparing for reuse - Recycling - Other Recovery - Disposal of Wasteâ€, waste processing and recycling additionally fulfills the duty to protect the environment and to preserve primary resources. In order to meet the demands of increasing recycling rates and the quality of recycled waste materials sensor based sorting is playing an important and increasing role in waste processing techniques.
Physical sorting represents an important step within the unit operations of waste treatment including crushing, screening and separating. The separation technology can be sub-classified in direct and indirect segregation procedures. Direct separation or conventional separation is utilizing interactions between the material properties of single particles and the force fields dependent on the used equipment. This becomes apparent regarding e.g. separation in magnetic fields which allows a selective segregation of ferrous items due to their difference in magnetic susceptibility. However, sensor based sorting is among the indirect separation methods as the working principle initially stipulates a specification of material attributes with detectors like color, electrical conductibility, density and spectral reflection, etc. The actual separation occurs subsequently by digital software based interpretation of the detector signals so that positively recognized particles separately can be blown out of the flight trajectory by compressed air from nozzles (PRETZ, 2005).

Like all public international law treaties, the Paris Climate Accords rely on national law for their implementation. The success of the agreement therefore depends, to a large extent, on the stepstaken or not taken by national governments and legislators as well as on the instruments and mechanisms chosen for this task. Against this background, the present article compares different approaches to the implementation of the Paris Agreement, using court decisions as a means to assess their (legal) effectiveness.
