TL;DR: A review of the current state of the art was performed in order to search directions toward the most profitable biochar farming applications as discussed by the authors, indicating that a promising direction might be its on-farm production followed by onfarm use and nutrient recycling, or more precisely, special fertilization applications.

TL;DR: Biochar refers to carbon-based dusty residues obtained from biomass pyrolysis and has been widely accepted as a promising method of carbon sequestration as mentioned in this paper, however, despite significant achievements in reduction of biochar production costs, high demand from the industry and energy sector keeps the biochar price still high.

TL;DR: In this article, the very first apparatus which continuously produces the biochar from the fermentation residue by utilizing waste heat from the cogeneration unit linked to the biogas station was designed and analyzed.

TL;DR: In this paper, the cheapest biochar derived from fermentation residues that are pyrolyzed by waste heat, was used as sorbent, and multiple austerity measures have been designed to modify the sorbent by ferric (Fe3+) and calcium (Ca2+) chemisorption.

TL;DR: A 5-year study revealed that this widespread practice lowers the level of mobile phosphorus, on average, by 62% as mentioned in this paper, and the quality of extractable phosphorus declines, since the biologically available calcium, magnesium and aluminum based phosphates are gradually being replaced by ferric phosphates (originating from the ferric sludge).
