“…The individual PCB concentrations did not exceed 1.000 mg/kg DM in the composted mixtures, except for the PCB 28 concentration in the material from composting cycle 70II c. Lazzari et al (2000) found PCB concentrations of below 0.03 mg/kg DM in sewage sludge, and similar concentrations, of about 0.020 mg/kg DM, were found in composted green and organic kitchen waste by Brändli et al (2007). Grossi et al (1998) found total PCB concentrations of 0.015-1.690 mg/kg DM in compost from Brazil, and these concentrations are similar to those that have been found in compost from Europe (1 mg/kg DM, on average).…”

“…Therefore it can be assumed that the decrease of PCBs concentration during biological treatment strongly depends on the degree of chlorination of individual congeners. Brändli et al (2007) conducting composting process of municipal waste in piles found that the concentration of higher chlorinated PCBs decreased while the concentration of lower chlorinated PCBs increased. Different relationship was observed by Michel et al (2001) during research on the composting process in the remediation of soil contaminated with PCBs.…”

“…Similar results have been found in Germany (de Souza Pereira and Kuch, 2005), whereas PCB concentrations almost 100 times higher have been found in sewage sludge in Brazil (de Souza Pereira and Kuch, 2005). Many researches confirm the presence of PCBs in sewage sludge and organic waste, which should be utilized (Blanchard et al, 2004;Brändli et al, 2007;Siebielska 2008). Two biological methods are generally used: composting and the anaerobic digestion.…”

“…Residues derived from anaerobic digestion can be used as fertilisers and soil conditioners with nutrients in digestates more readily available than those within slurry or fresh manure [4,5], although variability is associated with the feedstock used, the retention time and conditions within the AD unit [6].…”

Available online xxxKeywords: Nitrous oxide Anaerobic digestate Biochar Nitrification Denitrification a b s t r a c t This investigation examines nitrous oxide (N 2 O) fluxes from soil with simultaneous amendments of anaerobic digestates and biochar. The main source of anthropogenic emissions of N 2 O is agriculture and in particular, manure and slurry application to fields. Anaerobic digestates are increasingly used as a fertiliser and interest is growing in their potential as sources of N 2 O via nitrification and denitrification. Biochar is a stable product of pyrolysis and may affect soil properties such as cation exchange capacity and water holding capacity. Whilst work has been conducted on the effects of biochar amendment on N 2 O emissions in soils fertilised with mineral fertilisers and raw animal manures, little work to date has focused on the effects of biochar on nitrogen transformations within soil amended with anaerobic digestates. The aim of the current investigation was to quantify the effects of biochar application on ammonification, nitrification and N 2 O fluxes within soil amended with three anaerobic digestates derived from different feedstocks. A factorial experiment was undertaken in which a sandy loam soil (Dunnington Heath series) was either left untreated, or amended with three different anaerobic digestates and one of three biochar treatments; 0%, 1% or 3%. Nitrous oxide emissions were greatest from soil amended with anaerobic digestate originating from a maize feedstock. Biochar amendment reduced N 2 O emissions from all treatments, with the greatest effect observed in treatments with maximum emissions. The degree of N 2 O production and efficacy of biochar amelioration of gas emissions is discussed in context of soil microbial biomass and soil available carbon.

“…Paulsrud B, et al [2] pointed out that the PAHs concentration of Norwegian sewage sludge was 0.7 ~ 30 mg/kg, and the PAHs concentration was 0.25 ~ 16.28 mg/kg in parts of German. R. Brandli, et al [3] found that PAHs average concentration of Denmark was 1.2 mg/kg, and was obviously less than the limit value of the "Working document on sludge". J.D.…”

Abstract. Sludge agriculture application in future will be one of the main sewage sludge disposal ways in China. To ensure safety and environment of sewage sludge agriculture application, except to strengthen the research of sludge heavy metal, pathogen outside the organic contaminants will be one of the focuses of the future research, especially to strengthen the PAHs and NP/NPE. In order to reduce the environmental risks of sludge agriculture application, using biological aerobic fermentation processing technology treatment sludge can effectively reduce the organic contaminants, depress secondary pollution problem, which sewage sludge brings.
