A pilot test with dynamic biopiles was performed at the facility Sistemi Ambientali S.r.l. (Calcinate, BG). In a first step, the pilot test involved setting up 2 biopiles of approx. 18 mc to test separately the addition of a green composted soil improver and a fungal soil improver. To increase the bioavailability of the more recalcitrant fraction, a surfactant product was added. In the second step of the test, the efficacy of an oxidative treatment with persulfate, applied at the pretreatment or finishing stage, was tested.
