Data for the article: Comparative Environmental Assessment of Integrated Anaerobic Digestion and Pyrolysis Systems for Sewage Sludge Treatment: Impact Assessment using ReCiPe and USEtox methods
This dataset supports a comparative environmental assessment of integrated anaerobic digestion (AD) and pyrolysis systems for sewage sludge treatment. Six scenarios (S1–S6) are evaluated using ReCiPe and USEtox methods, covering configurations of AD, pyrolysis, and combinations with aqueous pyrolysis liquid (APL) recycling. The data includes process parameters, pollutant concentrations, energy balances, and ecotoxicity results.
The scenarios represent both conventional and innovative treatment pathways, including high-rate anaerobic digestion and the reintegration of APL. The dataset captures detailed information on chemical oxygen demand (COD), total solids (TS), methane yields, heating values, and degradation rates of persistent organic pollutants (POPs) such as PFAS, PAHs, PCBs, and PCDD/Fs. It also includes emissions data from pyrolysis. Foreground data is taken from the industrial plant and units already at the facility such as dryer, dewatering unit, and pyrolysis process. In addition, secondary data were retrieved from relevant literature and lab-scale reactor setups.
This comprehensive dataset enables reproducibility of life cycle impact assessments and facilitates the development of future sludge valorization strategies. It is particularly valuable for researchers and practitioners working on waste-to-energy systems, circular economy approaches, and environmental risk assessments of emerging treatment technologies.
