Abstract Increasing electronic waste (e‐waste) volume from the electronic industry and households has been creating primary health and environmental considerations because some of the e‐waste materials contain toxic substances. This study mainly focuses on the recovery of metals from e‐waste based on the melting temperatures of recyclable metals and centrifugal forces, thereby reducing the environmental pollution and recovering valuable metals for future use in the same or different industries. A perforated basket was designed and manufactured from stainless steel for feeding the chopped e‐waste. An induction furnace attached to a perforated basket was used to melt solder, aluminum, and other metals of the e‐waste. Around 95% of all metals was recovered from the e‐waste at different rotations (400–700 rpm) and temperatures (100–1,200°C) in less than a minute. The economic analysis indicated that this process was highly profitable and affordable for the future investment in the field. This study will also open new possibilities of extracting other metals from e‐waste by induction heats and centrifugal forces in affordable and fast manners for sustainable use of the electronic materials in the same or different industries.
