Exploring bioremediation potential: sustainable treatment of landfill leachate with oyster mushroom (Pleurotus ostreatus) grown on different agro-industrial waste.

Landfill leachate poses significant environmental risks due to its high concentrations of heavy metals and harmful physicochemical properties, which threaten ecosystems and human health. This study investigates the use of powdered oyster mushrooms (Pleurotus ostreatus) as a sustainable bioremediation agent for treating landfill leachate. The mushrooms were cultivated on three agricultural waste substrates, sawdust, corncob, and coconut fiber, and their efficiency in heavy metal removal was evaluated through batch adsorption experiments.
