As an efficient and low-cost adsorbent, biochar has been widely used in the adsorption and
removal of dyes, antibiotics and phenols from wastewater. Biochar is produced with gas and …

The ever-increasing rise in the global population coupled with rapid urbanization demands
considerable consumption of fossil fuel, food, and water. This in turn leads to energy …

The discovery of carbon-based catalysts triggers a wealth of research towards metal-free
catalysis. Various low-cost and earth-abundant biomaterials have been investigated to …

Antibiotics and antibiotic resistance genes (ARGs) have become a severe environmental
issue due to their widespread use in medicine and animal agriculture. Biochar is one of the …

Traditional fertilizers are highly inefficient, with a major loss of nutrients and associated
pollution. Alternatively, biochar loaded with phosphorous is a sustainable fertilizer that …

Transition from fossil fuels to non-conventional sources is needed to tackle the global
energy crisis and environment related issues. Thus, the use of organic waste generated from …

Safe disposal of excess sewage sludge (SS) produced from chemical/biochemical water
treatment processes has been a worldwide concern. In this work, sewage sludge biochar …

Sewage sludge (SS) pyrolysis to produce biochar is a vital approach for treating and utilizing
SS, while reducing the carbon footprint of SS disposal. However, the high inorganic content …

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 …

The appropriate conditioning of sewage sludge can facilitate its reuse as an adsorbent, such
as that for CO 2 capture to mitigate greenhouse effects. Herein, we treated raw sludge with …
