Modern approaches to treatment and recovery of secondary sludge of domestic sewage

open access: yesМеліорація і водне господарство, 2021
For today, pollution of the environment, in particular of surface waters, has led to an environmental crisis in many countries of the world. One of the reasons for this is the use of outdated approaches to the treatment and recovery of sewage sludge. The

Methane Generation Using an Anaerobic Biodigester From Waste Leachate Water

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Leachate wastewater (LWW) is characterized by slow biodegradation and low biogas production due to resistant materials and limited biological activity. Therefore, applying pretreatments is essential to improving biodegradation potential, which consequently boosts energy recovery.

Integrated Evaluation of Contaminant Profiles, Detection Techniques, and Management Strategies for Tannery Sludge

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This review article critically examines the environmental and health hazards of tannery sludge (TS), a complex by‐product of the leather tanning industry. TS is characterized by a diverse array of contaminants, including heavy metals like chromium, organic pollutants such as polycyclic aromatic hydrocarbons (PAHs), volatile organic compounds ...

Pollutant Emissions and Heavy Metal Migration in Co-Combustion of Sewage Sludge and Coal

open access: yesEnergies
The treatment of sewage sludge has become a global concern. Large amounts of sewage sludge can be disposed of by burning coal-mixed sludge. Thermogravimetric analysis and lab-scale combustion experiments in a drop tube furnace were utilized to study the ...

Scenario Analysis for Selecting Sewage Sludge-to-Energy/Matter Recovery Processes

open access: yesEnergies, 2021
The sewage sludges are the byproducts of the wastewater treatment. The new perspective of the wastewater value chain points to a sustainable circular economy approach, where the residual solid material produced by sewage sludge treatments is a resource ...

Ecotoxicity of sewage sludge- or sewage sludge/willow-derived biochar-amended soil

open access: yesEnvironmental Pollution, 2022
Co-pyrolysis of sewage sludge (SL) with plant biomass gains attention as a way to minimize SL-derived biochar drawbacks, such as high amount of toxic substances, low specific surface area and carbon content. The toxicity of soil amended with SL- (BCSL) or SL/biomass (BCSLW)-derived biochar was evaluated in long-term pot experiment (180 days).

Potassium Migration of Chestnut Shell Ashes Under Oxidizing Atmosphere and Its Modification Mechanism by Additives

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Biomass energy plays a critical role in alleviating environmental pressures. However, its relatively high content of alkali metals (especially for potassium) would cause ash‐related issues during combustion. To mitigate these issues, the potassium migration behaviors during chestnut shell (CS) conversion and the modification mechanisms of ...

Perceptions of sewage sludge

open access: yesWater Science and Technology, 2002
In Europe the agricultural reuse of sewage sludge is controlled by Directive but the combined forces of statutory regulation and “market” regulation have made the task of exploiting the scientifically recognised agricultural reuse benefits of sewage sludge arduous to achieve.

The Strategic Role of Waste Inventories in Industrial Symbiosis: A Simulation‐Based Perspective on Performance and Resilience of Industrial Symbiosis Networks

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Ensuring the resilience of industrial symbiosis networks (ISNs) has emerged as a key concern in the literature. However, existing studies focus on network‐level strategies, neglecting the potential benefits derived from strengthening the links between symbiotic partners.
