Applied Tests to Select the Most Suitable Fungal Strain for the Recovery of Critical Raw Materials from Electronic Waste Powder

Electrical and electronic wastes (WEEEs) are a potential source of raw materials. The main challenge for scientists is to set up reliable eco-friendly process recycle materials precious elements from WEEEs. Today, we know that fungi could play an active role in green technologies aimed at recycling valuable elements. bioaccumulation mechanism bioleaching activity filamentous fungal species have already been exploited fruitfully extraction processes. However, not all strains possess the same characteristics, it crucial choose right use. In this work, show method assess elements’ recovery efficiency WEEE using strains. A CAS agar screening test siderophore detection was carried out with three following plate accumulation performed on medium added 120 ppm waste powder highlighted differences capability, growth rate, biomass production. Among tested waste, yttrium, copper, palladium highest bioconcentration factor. results confirm biotechnological recover bench scale, highlighting importance effective tests most efficient strain each kind waste.
