Recovering phosphorous from biogas fermentation residues indicates promising economic results.
Josef Maroušek,Beata Gavurova +1 more
TL;DR: In this article, the authors proposed to activate the charred fermentation residues via calcium chloride and use the resulting sorbent to capture phosphorus (P) out of the fermentation residue's liquid fraction.

Mechanisms of metal sorption by biochars: Biochar characteristics and modifications
Hong-Bo Li,Xiaoling Dong,Evandro B. da Silva,Letuzia M. de Oliveira,Yanshan Chen,Lena Q. Ma,Lena Q. Ma +6 more
TL;DR: This review summarizes the characteristics of biochar (e.g., surface area, porosity, pH, surface charge, functional groups, and mineral components) and main mechanisms governing sorption of As, Cr, Cd, Pb, and Hg by biochar and includes competitive sorption mechanisms of co-existing metals.

Production and characterization of slow pyrolysis biochar: influence of feedstock type and pyrolysis conditions
TL;DR: In this article, a fixed-bed slow pyrolysis from various feedstock biomasses under a range of process conditions was used to produce biochar, which was characterized by proximate analysis, CHN-elemental analysis, pH in solution, bomb calorimetry for higher heating value, N2 adsorption for BET surface area and two biological degradation assays (oxygen demand, carbon mineralization in soil).

Analysis of Czech subsidies for solid biofuels.
Anna Mardoyan,Petr Braun +1 more
TL;DR: In this paper, the Czech Ministry of Environment argues that charcoal is not supported because of its high price per ton and the ecological criteria and price per energy should be also taken into account as analyzed in detail.

Effectiveness and mechanisms of phosphate adsorption on iron-modified biochars derived from waste activated sludge.
Qi Yang,Xiaolin Wang,Wei Luo,Jian Sun,Qiuxiang Xu,Fei Chen,Jianwei Zhao,Shana Wang,Fubing Yao,Dongbo Wang,Xiaoming Li,Guangming Zeng +11 more
TL;DR: Different iron modification was used to improve the phosphate adsorption capacity of waste activated sludge (WAS)-based biochar, and X-ray diffraction analyzes indicated that the iron in FeCl3-impregnated WAS-basedBiochar existed mainly in amorphous phase, as hematite andAmorphous hydroxides forms, which was of great benefit to the phosphate Adsorption.
