The removal of heavy metals from sewage sludge (SS) is attracting increasing attention
because the presence of toxic heavy metals in SS restricts its reuse or disposal, especially …

Our society currently faces three challenges, including resource depletion, waste
accumulation and environmental degradation, leading to rapidly escalating raw material …

When treating municipal wastewater, the disposal of sludge is a problem of growing
importance, representing up to 50% of the current operating costs of a wastewater treatment …

In this work, the influence of a low temperature (70–90° C) thermal treatment on anaerobic
digestion is studied. Not only the increase in biogas production is investigated, but attention …

In this study, the immobilization and risk assessment of heavy metals (HMs) in sewage
sludge (SS) during hydrothermal treatment combined with pyrolysis (HTP) was investigated …

The presence of heavy metals in municipal sludge restricts its use for agricultural purposes.
In this paper, the bioavailability and eco-toxicity of heavy metals in municipal sludge was …

Hydrothermal pretreatment was used for dewatering food waste digestate residue, and
biochar/biogas were generated from the separated solid and liquid phases via pyrolysis and …

Pyrolysis oils are a product of fast pyrolysis or liquefaction of biomass. Those dark brown
organic liquids are chemically a complex mixture and/or emulsion of water and degradation …

The hydrothermal (HT) treatment has been developed as a thermal pretreatment technology
to improve sludge dewaterability or to produce solid fuel by controlling sludge moisture …

During combustion of wastewater treatment sludge, the inorganic constituents are converted
into ash which contains the major fraction of the heavy metals present. The behaviour of …
