    Co-Authors: Malgorzata Kacprzak, Ewa Neczaj, Krzysztof Fijalkowski, Anna Grobelak, Anna Grosser, Malgorzata Worwag, Agnieszka Rorat, Helge Brattebo, Asgeir R Almas, Bal Ram Singh
    Abstract:

    The main objective of the present review is to compare the existing Sewage Sludge management solutions in terms of their environmental sustainability. The most commonly used strategies, that include treatment and Disposal has been favored within the present state-of-art, considering existing legislation (at European and national level), characterization, ecotoxicology, waste management and actual routs used currently in particular European countries. Selected decision making tools, namely End-of-waste criteria and Life Cycle Assessment has been proposed in order to appropriately assess the possible environmental, economic and technical evaluation of different systems. Therefore, some basic criteria for the best suitable option selection has been described, in the circular economy "from waste to resources" sense. The importance of Sewage Sludge as a valuable source of matter and energy has been appreciated, as well as a potential risk related to the application of those strategies.

  • Environmentally safe Sewage Sludge Disposal : the impact of liming on the behaviour of Cd, Cr, Cu, Fe, Mn, Ni, Pb, and Zn
    Journal of environmental monitoring, 2017
    Co-Authors: Peter Bukovec, Marjeta Stražar, Olga Burica, Radmila Milačič, Janez Ščančar
    Abstract:

    Dewatered Sewage Sludge containing relatively high total concentrations of Cr (945 mug ml(-1)), Cu (523 mug ml(-1)), Ni (1186 mug ml(-1)) and Zn (2950 mug ml(-1)) was treated with quicklime and sawdust for Sludge disinfection and post-stabilisation. The mobility of the heavy metals in the Sludge samples was assessed by applying a modified five-step Tessier sequential extraction procedure. Water was added as a first step for estimation of the proportion of the easily soluble metal fractions. To check the precision of the analytical work the concentrations of heavy metals in steps 1-6 of the extraction procedure were summed and compared to the total metal concentrations. The mass balance agreed within +/-3% for Cd, Cu, Cr, and Zn and within +/-5% for Ni, Pb, Fe and Mn. Data from the partitioning study indicate that in the lime-treated Sludge at a pH of 12 the mobility of Cu and Ni notably increased with the solubilisation of these metals from their organic and/or carbonate and Fe and Mn oxide and hydroxide fractions, respectively. Liming slightly decreased the proportion of other heavy metals in the easily soluble fractions while its impact on the partitioning between other Sludge phases was almost insignificant. Due to the increased solubility of Ni and Cu as well as potential Cr oxidation at high pH, liming cannot be recommended for Sludge disinfection. Addition of sawdust did not change the heavy metal partitioning.

  • A field method using microcosms to evaluate transfer of Cd, Cu, Ni, Pb and Zn from Sewage Sludge amended forest soils to Helix aspersa snails.
    Environmental Pollution, 2002
    Co-Authors: Renaud Scheifler, Annette De Vaufleury, M Ben Brahim, J-m Carnus, Pierre-marie Badot
    Abstract:

    Juvenile Helix aspersa snails exposed in field microcosms were used to assess the transfer of Cd, Cu, Ni, Pb and Zn from forest soils amended with liquid and composted Sewage Sludge. Zn concentrations and contents were significantly higher in snails exposed to liquid and composted Sludge after 5 and 7 weeks of exposure, when compared with control. Trends were less clear for the other metals. Present results show that Zn, among the cocktail of metallic trace elements (MTE) coming from Sewage Sludge Disposal, represents the principal concern for food chain transfer and secondary poisoning risks. The microcosm design used in this experiment was well suited for relatively long-term (about 2 months) active biomonitoring with H. aspersa snails. The snails quickly indicated the variations of MTE concentrations in their immediate environment. Therefore, the present study provides a simple but efficient field tool to evaluate MTE bioavailability and transfer.
