Abstract

Co-composting is suitable technology for recycling dredged sediments (S) and green wastes (GW), whose recovery are limited by their contamination and variability in composition, respectively. Some limitations in the process have been previously detected (e.g., limited thermophilic phase and low organic carbon content in the final product), thus restricting the use of co-compost for agricultural purposes. To optimize the co-composting and extend the application of the co-compost, the GW content in the piles (3S:1GW, 1S:1GW and 1S:3GW) and the pile volumes was increased. At the end of the process, the co-compost properties were compared to current legislation. The co-composting’s impact on the environment and its possible replacement of peat were also assessed by LCA. Maturity and stability were reached in all piles: enzyme activities ( 100%) decreased, together with hydrocarbons (− 162%/− 48%) and PCB (
