abstract = {Untreated sewage sludge (SS) and misused stabilization technologies have contributed
to great contamination and the accumulation of various pollutants in agricultural soils.
Regarding micro-pollutants’ degradation, scalable and effective technologies are still scarce.
Although many attempts at composting adaptations have been discussed, only a few have
been tested individually under outdoor conditions. To investigate different composting
methods (bioaugmentation and semipermeable cover) for the removal of micro-pollutants
frequently found in SS, we performed a set of on-site experiments. Windrows of SS and
olive pruning were used as the compostable material and were subjected to (i) bioaugmentation with the fungus Penicillium oxalicum, (ii) covered composting, (iii) covered and
bioaugmented composting, and (iv) a conventional composting pile, which was included as
a control. The entire experiment lasted 99 days. Bioaugmentation without cover increased
the phosphorus content, favored a reduction in heavy metal content, and was the only
treatment that reduced carbamazepine at the end of the process. Moreover, the inoculation
of P. oxalicum under semipermeable cover increased the richness, diversity, and dominance
of specific microbial taxa and total bacterial abundance. The four mature composts obtained
met the standards required to be classified in the B fertilizer category, showing that we
reduced most of the micro-pollutants, and passed the germination test.},
