Electronic scrap concentration and metal mobilization of e-waste leachates at different concentrations using A. niger for the biotechnology treatment of Cu (II) ions contained in solid waste [27, 31].

Element	Electronic scarp concentration (g/L)
	1 (g/L)	10 (g/L)	50 (g/L)	100 (g/L)
	Metal mobilization (%)
Cu^2+ (copper (II) ions)	85 (0.07 g/L)	86 (0.69 g/L)	70 (2.80 g/L)	8 (0.60 g/L)
