Vermicomposting technology as a process able to reduce the content of potentially toxic elements in sewage sludge
Original language description
The objectives of this study were to evaluate the potential of vermicomposting to decrease PTEs (As, Cd, Cr, Cu, Pb, and Zn) during composting of SS and whether the bioaccumulation of PTEs in earthworm tissue depends on feed quality. The initial SS was mixed in triplicate with varying proportions of pelletized wheat straw (PWS) (0%, 25%, 50%, and 75% (w/w)) along with a control (100% SS, no earthworms). The experiment was conducted for 120 days using Eisenia andrei. In comparison to the control, mixing SS with PWS reduced content of PTEs demonstrating that the accumulation of PTEs in the earthworm tissues explains the low content of PTEs in the vermicompost. The total carbon loss showed a significant relationship with BCFAs (r = 0,989, p 0,011), BCFCd (r = 0,996, p 0,004), BCFCr (r = 0,977, p 0,023), BCFCu (r = 0,999, p 0,000), and BCFZn (r = 0,994, p 0,006). The variant containing 75% PWS (VC4) appeared to be a suitable SS mixture to reduce PTEs.
