TL;DR: An extended overview of phase-mineral transformations of organic and inorganic matter that occur during biomass combustion was conducted in this article, where it was demonstrated that the phase composition of BA is polycomponent, heterogeneous and variable and includes: (1) mostly inorganic material (IM) composed of non-crystalline (amorphous) and crystalline to semiscale constituents; (2) subordinately organic matter (OM) consisting of char and organic minerals; and (3) some fluid matter associated with both IM and OM.

TL;DR: In this paper, the influence of preparation methods, process parameters, and modification methods on the physicochemical properties of biochar were discussed, as well as the mechanisms of the biochar in the remediation of soil pollution.
Abstract: As a new functional material, biochar was usually prepared from biomass and solid wastes such as agricultural and forestry waste, sludge, livestock, and poultry manure. The wide application of biochar is due to its abilities to remove pollutants, remediate contaminated soil, and reduce greenhouse gas emissions. In this paper, the influence of preparation methods, process parameters, and modification methods on the physicochemical properties of biochar were discussed, as well as the mechanisms of biochar in the remediation of soil pollution. The biochar applications in soil remediation in the past years were summarized, such as the removal of heavy metals and persistent organic pollutants (POPs), and the improvement of soil quality. Finally, the potential risks of biochar application and the future research directions were analyzed.
