    Abstract This work explores the effects of amending a loamy sand soil with hydrochars having different physicochemcial characteristics. The effects of different hydrochars on emissions of the greenhouse gases nitrous oxide (N₂O) and carbon dioxide (CO₂) were investigated together with the relationship between the hydrochar's mineral nitrogen content and the soil microbial biomass. Soil samples were amended with eleven different hydrochars and feedstocks having different carbon and nitrogen contents at application rates of 5 t ha⁻¹ and 25 t ha⁻¹. Microbial immobilization was the main mineral nitrogen sink in soil following hydrochar application. Moreover, the processing conditions applied during hydrochar production (i.e., the pyrolysis temperature and residence time) had significant effects on N₂O and CO₂ emissions: treatment with incubated hydrochars yielded significantly lower N₂O emissions than treatment with non-carbonized feedstocks, particularly at the highest level of hydrochar application (25 t ha⁻¹). Further analysis revealed that increasing the process temperature and residence time during hdyrochar production significantly increased the final product's total organic carbon content but reduced its content of hot water extractable carbon. Hydrochars produced with higher process temperatures and longer residence times therefore yielded lower CO₂ emissions during a 44-day incubation experiment than raw feedstocks or hydrochars produced under less severe conditions. Hydrochars formed from sewage sludge at high process temperatures and with long residence times are thus promising soil additives for reducing GHG emissions.

    Abstract Wastewater-based monitoring of SARS-CoV-2 has become a promising and useful tool in tracking the potential spread or dynamics of the virus. Its recording can be used to predict how the potential number of infections in a population will develop. Recent studies have shown that the use of passive samplers is also suitable for the detection of SARS-CoV-2 genome copies (GC) in wastewater. They can be used at any site, provide timely data and may collect SARS-CoV-2 GC missed by traditional sampling methods. Therefore, the aim of this study was to evaluate the suitability of passive samplers for the detection of SARS-CoV-2 GC in wastewater in the long-term at two different scales. Polyethylene-based plastic passive samplers were deployed at the city-scale level of Leipzig at 13 different locations, with samples being taken from March 2021 to August 2022. At the smaller city district level, three types of passive samplers (cotton-cloth, unravelled polypropylene plastic rope and polyethylene-based plastic strips) were used and sampled on a weekly basis from March to August 2022. The results are discussed in relation to wastewater samples taken at the individual passive sampling point. Our results show that passive samplers can indicate at a city-scale level an accurate level of positive infections in the population (positive-rate: 86 %). On a small-scale level, the use of passive samplers was also feasible and effective to detect SARS-CoV-2 GC easily and cost-effectively, mirroring a similar trend to that at a city-scale level. Thus, this study demonstrated that passive samplers provide reproducible SARS-CoV-2 GC signals from wastewater and a time-integrated measurement of the sampled matrix with greater sensitivity compared to wastewater. We thus recommend the use of passive samplers as an alternative method for wastewater-based epidemiology. Passive samplers can in particular be considered for a better estimation of infections compared to incidence levels.

    Abstract Large amounts of labile compounds are adsorbed to the surface of chars produced by hydrothermal carbonization (HTC). The aim of this study was to characterize the core and adsorbed fractions of hydrochars and to gain knowledge about the possibility to remove phytotoxic compounds by washings with water. Chars were produced by HTC of sewage sludge at different temperatures (180 – 200 °C) and over different periods of time (4 – 8 h). For comparison one pyrolysis char produced by thermocatalytic low temperature conversion (LTC) at 400 °C for 1 h was included in the study. The chars and their feedstocks were treated varying the duration (1 x 15, 1 × 30 and 1 × 60 min) and number (2 x 60 and 3 × 60 min) of washings. Physicochemical properties, including the molecular structure of the test materials, and their effects on germination and plant growth were analysed. Element concentrations and phytotoxic effects were reduced and the number of washings had a stronger effect than their length of time. Intensive washings with water reduced the hydrochars’ portion of biodegradable compounds significantly. However, also plant available nutrients were lost by washing with water, decreasing the value of hydrochars as a soil amendment.

    Abstract Anaerobic thermochemical carbonization can be used to treat sewage sludge and facilitate its reuse. The aim of this study was to compare and evaluate chars produced by pyrolysis and hydrothermal carbonization (HTC) of sewage sludge, so-called sewchars, under varying process conditions in terms of their soil amelioration potential. Three different sewage sludges, two pyrolysis and four HTC sewchars were evaluated with respect to their stability in soil, perspective for nutrient recycling and potential use as soil amendments. The sewchars were produced at different temperatures (pyrolytic low temperature conversion LTC 400°C; PYREG pyrolysis 700°C; HTC 180–200°C) and for varying treatment times (LTC and PYREG 1h; HTC: 4–8h). O/C and H/C ratios of about 0.7 and 1.8 respectively, indicated that HTC sewchars will tend to be less recalcitrant in soils than pyrolysis sewchars. The duration and temperature of HTC correlated positively with the chars’ contents of adsorbed labile carbon and nitrogen compounds. However, HTC failed to increase the chars’ resin-extractable phosphorus contents. The cation exchange capacity of sewage sludge was reduced by HTC but stayed on a higher level than after pyrolysis. With increasing treatment temperature, the pH, ash (content) as well as macro- and micronutrient contents increased. Pyrolysis sewchars also accumulated heavy metals; however their contents were lower than those reported previously. An enrichment of heavy metals was also observed for the HTC sewchars, albeit to a much lesser extent.
