“…Similarly, Zn and Cu contents in anaerobically digested sewage sludge were found to be thirty and ten times higher, respectively, than the contents in PDSS. Moreover, when the comparison was carried out between the PDSS and the straw described in Scaglia et al it emerged that the two materials did not differ significantly [22].…”

“…Pathogens may also contaminate other biomasses classified as CMCs, especially when the production process is not carried out in optimal conditions. For instance, pathogens can survive during composting if the materials do not reach a sufficiently high temperature during the active phase of the process, leading to the production of composts that do not comply with pathogens limits [22,48].…”

“…In addition, recent literature has pointed out that biomasses commonly used in agriculture and reported as CMCs (e.g., compost and manure) can contain high concentrations of heavy metals and emerging organic pollutants (i.e., pharmaceuticals). Significant concentrations of dioxins and heavy metals were found in compost from green wastes [22], whereas antibiotics were reported to be the major contaminants in processed and unprocessed manures [23]. Therefore, definitions of CMCs, which rely only on the definitions and origins of biomasses may be misleading, since certain sewage sludge might show better agronomic and environmental performance than compost, manures and other secondary sources classified in the CMCs list.…”

The fertilizer framework in the European Union has recently been reviewed by EU Regulation 1009/2019 that excluded sewage sludge from the list of the possible constituents of organic fertilizers relying on their origin, not on their quality. This paper aimed to carry out a complete characterization of sewage sludge obtained from a pharmaceutical manufacturing process (PDSS) to demonstrate that sewage sludge obtained from a standardized and controlled manufacturing process can be safely recycled as organic fertilizer. The agronomic and environmental characteristics of the PDSS product were analyzed and compared to other organic fertilizers. Its fertilizing potential was also evaluated through plant growth trials. PDSS was characterized by a high concentration of total N (6.6% w/w), which was all present in organic form. PDSS also showed a low concentration of heavy metals, an absence of pathogens and low concentrations of organic contaminants. Plant growth trials showed that the PDSS was able to improve lettuce and carrot growth (+25 and +46% of dry weight compared to the unfertilized control), as well as their physiological status. Considering all the results, the exclusion of sewage sludge relying only on its origin and not on its quality appears to conflict with the principles of the circular bioeconomy.

Tomato peels and seeds (TP) are the most abundant canning industry waste actually used to produce biogas. TP is rich in lycopene (lyc) and represent a more sustainable feedstock than tomato fruits actually employed. It was therefore chosen as feedstock together with supercritical CO 2 extraction (SFE-CO 2) technology to develop a TP-SFE-CO 2 biorefinery, topic scarcely investigated. Two TP were tested and although TP-SFE-CO 2 parameters were the same, lyc recoveries depended by peel structure changes occurred during pre-SFE-CO 2 drying step. Higher moisture (102.7 g kg-1 wet weight) permitted 97 % lyc recovery and gave a water-in-oil emulsion as extract. Mass balance confirmed that lyc isomerisation did not cause lyc losses. After a significant oil extraction, exhaust TP showed a biodegradability 64% higher than the raw one, attributable to fibre structure disruption. The biorefinery proposed (SFE_CO 2 +anaerobic digestion) determined positive economic revenue (+787.9 € t-1 TP) on the contrary of the actual TP management.
