Sewage sludge was pyrolyzed in order to assess the effect of pyrolysis temperature, residence time and biomass chemical impregnation on the yield of biochar production. The pyrolysis temperature was a key factor affecting biochar yield, while the highest yield was obtained at a temperature of 300 °...
Sewage sludge biochar (SSB) has demonstrated a large potential to improve soil quality, availability of nutrients, particularly phosphorus (P), and increase crop productivity. There is a lack of information on the effect of P from SSB on the soil microbiota, especially on arbuscular mycorrhizal ...
Wastewater treatment and the efficient use of sewage sludge biochar are critical in addressing the needs of ever-increasing population in the world. Recently, phosphorus (P) removal from wastewater has become highly relevant and important, primarily to reduce eutrophication in surface water...

Biochar addition to soil has been proposed to improve plant growth by increasing soil fertility, minimizing bioaccumulation of toxic metal(liod)s and mitigating climate change. Sewage sludge (SS) is an attractive, though potentially problematic, feedstock of biochar. It is attractive because of its ...
We concluded that sawdust feedstock promoted nutrient availability in the resulting biochar and induced higher activity of nutrient mineralizing enzymes, whereas zeolite slowed down the release of nutrients from soil and putatively immobilized enzymes. This joint effect of sewage sludge biochar, sawdust and...
example, sewage sludge conversionto biochar may reduce the leaching of trace metals [1], increase the enzymatic activity of soils [2], and also reduce the bioaccumulation of trace metals [1,3] and PAHs [1,3e6]. Due to its large sorption capacity, bio- char has an ability of binding tr...
In summary, the downstream research of sludge focuses on the preparation of biochar from sludge and its application67,68,69,70,71,72, energy and nutrient recovery73,74,75,76, removal of toxic and harmful substances and heavy metals from sludge77,78,79,80,81. There are also some reports ...

This paper assesses the feasibility of using sewage treatment sludge biochar as a low-carbon 100% waste-based alternative to traditional alkali agents. Two biochar:slag ratios (0.5:0.5 and 0.67:0.33) were added to an artificial soil at dosages of 7.5 and 10% by dry weight and cured for ...
