Blending waste biomass for co-pyrolysis is generally regarded as a promising method for
reduced-volume, value-added, and hazard-free treatment of sewage sludge. Hence, a …

The introduction of heavy metal-free biomass into the sewage sludge (SS) pyrolysis can
effectively improve the biochar properties and reduce the bioavailability and toxicity of heavy …

A novel type of biochar was produced by mixing bamboo sawdust with sewage sludge (1: 1,
w/w) via a co-pyrolysis process at 400–600° C. Changes in physico-chemical properties and …

Biochar production by pyrolysis of sewage sludge (SS) is one of effective ways to realize
resource recovery and harmless treatment of SS. However, biochar prepared by direct …

Co-pyrolysis of sludge and biomass was conducted to produce biochar with heavy metals
solidification. The synergistic coupling mechanism and the surface functional groups and …

Proper disposal of ever-increasing amounts sewage sludge and cotton stalks is a challenge
around the world, and conversion of these wastes into biochars via co-pyrolysis may be a …

Conversion of sewage sludge and agriculture straws into biochars via co-pyrolysis is a
promising strategy for the safe disposal and reuse of sewage sludge. In this study, biochars …

The safe disposal and utilisation of sewage sludge can be challenging because of the
potential environmental risks posed by heavy metals in the sludge. Conversion of sewage …

Sewage sludge (SS) has been proved to be a good feedstock material for the production of
biochars. However, the problem is that the total/leachable contents of some heavy metal …

Co-pyrolysis of straws with manures has been found effective to mitigate heavy metal risks in
manure-derived biochars. This study further investigated co-pyrolysis strategy on the levels …
