Neutralization of red mud using bio-acid generated by hydrothermal carbonization of waste biomass for potential soil application
TL;DR: In this article, a novel process employing natural biomass without addition of chemicals was proposed for remediation of red mud Hydrothermal carbonization (HTC) of local fallen leaves was conducted to obtain solution containing bio-acids (SBA) and hydrochar.

Plant and soil responses to hydrothermally converted sewage sludge (sewchar)
Tatiane Medeiros Melo,Michael Bottlinger,Elke Schulz,Wilson Mozena Leandro,Adelmo Menezes de Aguiar Filho,Hailong Wang,Hailong Wang,Yong Sik Ok,Jörg Rinklebe,Jörg Rinklebe +9 more
TL;DR: The positive effect of sewchar in addition to phosphorous on the plant response and soil properties suggests that the residual effect of Sewchar could be a promising alternative as a soil amendment for partly replacing mineral fertilizers.

TL;DR: It was found that biochar at 5% (BC5) and the mixture of biochar and apatite at 3% resulted in the greatest reduction of exchangeable forms of Cd, Pb and Zn, which was a major environmental issue for both farmers and the population as a whole.

Slow pyrolyzed biochars from crop residues for soil metal(loid) immobilization and microbial community abundance in contaminated agricultural soils.
Avanthi Deshani Igalavithana,Jinje Park,Changkook Ryu,Young Han Lee,Yohey Hashimoto,Longbin Huang,Eilhann E. Kwon,Yong Sik Ok,Sang Soo Lee +8 more
TL;DR: No considerable effects of biochars on the microbial community abundance and dehydrogenase activity were found in both soils, however, the silicon content in biochar is also an influencing factor in increasing the As mobility.

A Bio-Functions Integration Microcosm: Self-immobilized Biochar-Pellets Combined With Two Strains of Bacteria to Remove Atrazine in Water and Mechanisms
TL;DR: The kinetic adsorption results showed that the biosorption of biochar by pellets followed a pseudo-second-order kinetic model, and the ATZ removal ability and reusability of SIB were significantly increased by biochar.

Dynamic molecular structure of plant biomass-derived black carbon (biochar)
TL;DR: A molecular-level assessment of the physical organization and chemical complexity of biomass-derived chars and, specifically, that of aromatic carbon in char structures suggests the existence of four distinct categories of char consisting of a unique mixture of chemical phases and physical states.
