“…The pyrolysis process of biochars can lead to the conversion of P to more recalcitrant forms. As a result, a higher proportion of HCL-P and Rs-P accumulate in HBC [5,32]. Adhikari et al [33] reported a somewhat higher proportion of HCL-P (57.60%) in the biochar prepared at 400 ℃.…”

Conditioning alkaline soil with acidic phosphorus-rich biochar might contribute to achieving sustainable phosphorus (P) use and residue management. In this study, acidic phosphorus-rich biochar was prepared from halophyte species biochar (HBC) by the modification of H3PO4 (P-HBC) and H4P2O7 (PA-HBC). The P combination method and fractions in biochars were characterized, and the effects of biochars on P fractions in different types of alkaline soil were examined with incubation experiments. The results showed that the pH values of P-HBC (3.31) and PA-HBC (2.17) decreased significantly, and the total P content increased to 4.66 g·kg− 1 and 5.24 g·kg− 1, respectively. The spectral analysis confirmed the doping of P and acid groups in biochar. The addition of modified biochars in alkaline soils will makes the soil tend to be neutral. Sequential extraction of soil P confirmed that biochars application facilitated the transformation of stable P into active fractions, with greater effects from modified biochars than HBC. Activation mechanism of biochar to soil P fractions varies from soil types. Overall, acidic phosphorus-rich biochars can be employed to improve alkaline soil properties and increase P activity.

“…Jindo et al ( 2016 ) reported that adding biochar to compost stabilised the chemical component of fulvic acids and enhanced the degradation of humic acids, resulting in higher environmental stability. Wei et al ( 2021 ) evaluated woody peat and biochar co-composting. They revealed that co-composting reduced the humic to fulvic acid ratio compared to the control, indicating that the humification process is optimised following co-composting.…”

“…Wei et al ( 2021 ) observed that the total phosphorus concentration increased during the co-composting operation of woody peat and biochar due to the biodegradation of organic materials. However, the authors noted that the total phosphorus content of the co-compost could not be increased above that of control.…”

Biochar for agronomy, animal farming, anaerobic digestion, composting, water treatment, soil remediation, construction, energy storage, and carbon sequestration: a review

In the context of climate change and the circular economy, biochar has recently found many applications in various sectors as a versatile and recycled material. Here, we review application of biochar-based for carbon sink, covering agronomy, animal farming, anaerobic digestion, composting, environmental remediation, construction, and energy storage. The ultimate storage reservoirs for biochar are soils, civil infrastructure, and landfills. Biochar-based fertilisers, which combine traditional fertilisers with biochar as a nutrient carrier, are promising in agronomy. The use of biochar as a feed additive for animals shows benefits in terms of animal growth, gut microbiota, reduced enteric methane production, egg yield, and endo-toxicant mitigation. Biochar enhances anaerobic digestion operations, primarily for biogas generation and upgrading, performance and sustainability, and the mitigation of inhibitory impurities. In composts, biochar controls the release of greenhouse gases and enhances microbial activity. Co-composted biochar improves soil properties and enhances crop productivity. Pristine and engineered biochar can also be employed for water and soil remediation to remove pollutants. In construction, biochar can be added to cement or asphalt, thus conferring structural and functional advantages. Incorporating biochar in biocomposites improves insulation, electromagnetic radiation protection and moisture control. Finally, synthesising biochar-based materials for energy storage applications requires additional functionalisation.

“…Biochar have been reported to enhance the effectiveness of biowastes composting and to improve the quality of the final product ( Chavez-Garcia et al., 2020 ; Godlewska et al., 2017 ; Liu et al., 2017 ; Pandiyan et al., 2021 ; Teodoro et al., 2020 ; Wang and Zeng, 2018 ; Wu et al., 2017b ; Xiao et al., 2017 ; Yin et al., 2021 ; Zhang et al., 2021c ). Biochar has been shown in literature to reduce gaseous emissions ( Awasthi et al., 2017 , 2020a ), reduce N and C losses ( Awasthi et al., 2020b ; Zhang et al., 2021a ), reduce composting duration ( Qu et al., 2020 ), increase humification ( Vandecasteele et al., 2014 ; Jindo et al., 2016 ), improve aeration and porosity ( Zhang et al., 2014 ), reduce bioavailable HMs fraction ( Cui et al., 2020b ), reduce ARGs ( Qian et al., 2019 ; Cui et al., 2016a , 2016b ), improve microbial activity ( Awasthi et al., 2020b ; Lia et al., 2020 ; Qu et al., 2020 ), improve available nutrient ( Zainudin et al., 2020 ; Wei et al., 2021 ), and reduce ecotoxicity in compost ( Wang et al., 2017 ).…”
