“…did not improve the efficiency of oxidation treatment, due to the scavenger effect of both factors. Similar behaviour was obtained in Hu et al [16] investigation in which a semi-solid Fenton's process was used to hazardous solid waste detoxification. The model equation representing C-CO 2 released from oxidation reaction may be expressed through Eq.…”

This study aims to explore an innovative approach consisting of the Fenton's process to stabilise organic wastes as an alternative to the traditional aerobic decomposition (composting). Digestate from the anaerobic digestion of the organic fraction of municipal solid wastes was taken from a mechanical-biological treatment plant and was thoroughly characterised regarding physical, chemical and biological properties. This sludge contained around 7.8 g Fe kg TS -1 , which can be beneficial to the chemical oxidation. However, the use of zero-valent iron nanoparticles or iron(II) salt revealed treatment can be improved by adding extra iron into the system. The response surface methodology determined that the best peroxidation conditions were 35.6 g H 2 O 2 kg TS -1 and 33.1 g Fe 2? kg TS -1 , while maintaining constant pH 3, L/S 5 and room temperature. The chemical treatment enhanced the stability, reducing the oxygen uptake rate from 4.63 to 2.57 g O 2 kg VS -1 h -1 . Moreover, the germination index increased from 37 to 99.9 %, which means the treatment yielded a non-phytotoxic product. The outcomes of the present study are promising and open a new pathway for the Fenton peroxidation in semi-solid processes since this fast method can be very competitive when compared with the slow composting technology.

“…Some studies [12,14,15] stressed the possibility of improving sludge dewaterability by Fenton's reagent. Hu et al [16,17] have investigated a semi-solid Fenton process for hazardous solid waste detoxification. Recently, Beneduci et al [18] proposed the use of iron salts for producing soil amendments from organic wastes.…”
