· As a followup to this issue. I was unable to find the timer mechanism but was able to replace the light sensors in my two boxes. The light sensors are still manufactured by Intermatic (Intermatic K4021C 120-Volt Fixed Position Thermal Photocontrol) and the system now works fine as a dark to daylight controller.

· In the early stages simple and rough processes for precious metals recycling were widely adopted. For example recycling precious metals from e-waste mainly includes manual dismantling aqua regia leaching or open burning. These methods not only have low recovery rate but also pollute the environment (Wang and Xu 2015).
· According to Chancerel and Rotter (2009) the performance of the recycling process including the previous mentioned operations strongly depends on the composition of the considered WEEE and can be improved through a "recycling oriented characterization" of the waste fed to the process. It must be taken into account that no standards exist for the characterization of WEEE but some attributes have been recognized as important to perform a correct recycling
· A recycling oriented characterization of end-of-life mobile phones was carried out. • Characterization was developed in a zero-waste-perspective aiming to recover all the mobile phone materials.. Plastic frames and printed circuit boards were analyzed by electronic and chemical imaging.
