Primary and Activated Sludge Biogas Production: Effect of Temperature
Sewage sludge management is a problem of growing importance. Anaerobic sewage sludge stabilization is commonly used technology, where organic matter contained in primary and activated sewage sludge is converted into biogas, so both, pollution control and

ABSTRACT This study examines how carbon accounting can be used to govern, not merely report, circular economy principles in shipping corporations. Grounded in institutional theory and aligned with the UN 2030 Agenda, this study introduces circular harmony as an accounting design principle: Circular interventions are embedded in a single well‐to‐wake ...

Biomass and Yield of Peanut Grown on Tropical Soil Amended with Sewage Sludge Contaminated with Lead
Application of sewage sludge with high lead (Pb) contents may pollute soils and contaminate crops. The objective of this work was to evaluate peanut responses to application of sewage sludge with varying Pb contents in order to supply phosphorus (P) to ...

Schematic illustration of an integrated strategy for soybean whey wastewater (SWW) treatment combining high‐throughput air flotation sorting with microbial monitoring and interaction analysis. This dual approach enables efficient nutrient recovery from polysaccharide‐ and protein‐rich SWW, eliminates rancid pollution, and achieves sustainable nutrient ...

Methane emissions from fresh dairy cattle and pig slurry
Abstract During manure storage, methane (CH4) is produced by anaerobic decomposition of organic matter by methanogens. Frequent removal and further processing of manure from the barn can reduce CH4 emissions. However, little is known about how much CH4 is lost during the adaptation of methanogens to the changing environment from the gut to storage. The

Recovering nutrients from urine – A golden opportunity for sustainable fertiliser production
Agricultural industrialisation has led to levels of nutrients in the environment that are well above safe operating limits, yet fertiliser use is necessary to feed a growing population. The recovery of nutrients from human urine in large, developed cities may offset some of the ecological and economic impacts associated with fertiliser production, as ...

Removal of Inorganic Contaminants Using Sodalite Synthesized From Alum Sludge
Alum sludge was successfully converted into sodalite adsorbent through a mild hydrothermal for contaminants adsorption in wastewater. ABSTRACT The growing concern over water contamination by potentially toxic metals underscores the need for sustainable and cost‐effective remediation strategies. In this study, sodalite (SOD‐Na) was synthesized from alum

ABSTRACT During the past decade, major upgrades have been made to the Kitchener and Waterloo wastewater treatment plants (WWTPs) in the Grand River watershed in Ontario, Canada. As part of efforts to evaluate the effectiveness of these investments (>$450 M CDN), a benthic macroinvertebrate (BMI) monitoring program was initiated by sampling upstream and
