Abstract: The objective was to reduce variation in the outcome of a corona-electrostatic separation process for solid waste recycling by finding operating conditions (high-voltage level, roll speed, splitter position) under which uncontrollable variation in |noise factors| (ambient humidity, metal content in the feed) has minimal impact on the quantity and the quality of the recovered products. The samples of processed material were prepared from mm-size chopped electric wire wastes. The design and noise factors were first analysed using the classical Taguchi|s approach, then combined into one single experimental design, so that a regression model of the process will be fitted.
Keywords: solid wastes; electrostatic separation; corona discharge; robustness; experimental design; relative humidity; waste recycling; chopped electric wire; electric wire waste; Taguchi methods.
