This study examined the role of epoxy, present in glass fibre reinforced laminate (FR-4), in inhibiting the leaching of copper from electronic wastes (e-wastes). FR-4 makes up the majority of the base materials used in printed circuit boards and would be a prevalent polymeric constituent of e-wastes. To mimic the spent medium based leaching of fungi, leaching of e-waste was performed using citric...
Bioleaching of copper-rich electronic waste material was carried out using mesophillic Acidithiobacillus thiooxidans. The leaching behaviour of copper was investigated using three methods: abiotic chemical leaching using inorganic sulphuric acid, indirect leaching using bacterially generated sulphuric acid and by direct leaching using the acidophilic bacteria. The yield of bacterially generated sulphuric...
