In this study, biochar was prepared using waste dander and CaSa(4) was generated on its surface to enhance soil carbon sequestration ability. The results showed that the application of Ca-BC reduced soil organic carbon mineralization rate, increased soil moisture content and organic carbon content. Bioinformatics analysis also revealed a shift in bacterial phyla with the application of Ca-BC.
In order to reduce CO2 emissions, as well as realize the resource utilization of waste dander (WD) and the goal of international peak carbon dioxide emissions and carbon neutrality, Biochar was prepared with WD via pyrolysis technology, achieving CaSa(4) in situ generated on its surface, which could be used to inhibit soil organic carbon (SOC) from mineralizing and enhance soil carbon sequestration ability. The characterization results showed that the unstable carbon (C) structures as well as more conjugated structures were generated on Ca-BC, obtaining an increased C sequestration of Ca-BC to 21.70 %. With the application of Ca-BC, the mineralization rate of SOC was reduced to 0.451 mg CO2/(g.d), and the soil moisture content, pit and TOC content were increased to 45.48 %, 7.96 and 47.19 %. In addition, the bioinformatics analysis and redundancy analysis revealed that the application of Ca-BC promoted bacteria to convert into the stable C-dominant phyla (Firmicutes).
