Regenerative Energie
Our economy increasingly depends on metals and minerals, which are present on earth in only low concentration. Waste electronic equipment contains strategically relevant metals and minerals and is therefore an important source for recovery of secondary raw material.
Flat display panels (FDP) have largely replaced Cathode Ray Tubes (CRT). The vast majority of flat display panels (more than 75 %) are based on LCD (Liquid Crystal Display) technology. The future relevance of FDP based on so-called OLED (Organic Light-Emitting Diode)-technology cannot be predicted precisely but it is likely that it will displace other display-technologies.
The change of technology from CRT to FDP entails challenges in recycling questions:
ï‚· The amount of waste rises in foreseeable future.
ï‚· Flat display panels with LCD technology contain large amounts of hazardous mercury, which carries a risk for employees in treatment plants.
ï‚· By law components, which contain hazardous substances, have to be removed before recy-cling.
ï‚· Plastic and metal components are valuable, e.g. LEDs contain critical metals like gallium.

Die innerstaatliche Umsetzung des Pariser Klimaschutzübereinkommens
- ein Rechtsvergleich
© Lexxion Verlagsgesellschaft mbH (8/2024)
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.
