“…The use of machine learning and artificial intelligence principles could lead to a better understanding of the effectiveness of biochar remediation of degraded soils as well as short‐ and long‐term effects (Cao et al., 2016; Palansooriya et al., 2022). While biochar research has employed machine learning techniques, current work has focused on model training using laboratory‐scale data (Wang et al., 2024).…”

“…Currently, a little information is available on the application of artificial intelligence and machine learning in the fields of biochar preparation (Cao et al, 2016) and heavy metal remediation (Palansooriya et al, 2022). Various factors, such as biochar characteristics, levels of biochar application, complex soil degradation problems, soil properties, environmental climate and temporal conditions can affect the effectiveness of biochar in remediating degraded soils (Ma et al, 2023;Wang et al, 2024;Wei et al, 2024). Such complex conditions can be predicted and optimized by models generated by machine learning.…”

Biochar, a black carbon material produced by high‐temperature, low‐oxygen pyrolysis of organic solids, can improve soil properties and realize carbon neutrality. However, how to effectively produce and apply biochar in the face of the complex soil environment and intractable widespread land degradation is still uncertain. This review is based on 1073 sets of data in 316 publications to address this issue. Firstly, the impact of different process parameters, namely feedstocks, pyrolysis temperature and activation on physicochemical properties of biochar are systematically summarized. Secondly, the effect of biochar on different soil degradation problems are reviewed from the perspective of the interaction between the physicochemical properties of biochar and soil characteristics. The “matching” of biochar properties, level of degradation and environmental factors can be used to design the desired biochar. Finally, future research should focus on biochar aging and costs and benefits of using biochar. The concept of “artificial intelligence designed biochar” is discussed to improve the degree of automation in biochar production and the predictability and suitability of its application for specific cases.

“…There are a variety of biogas upgrading technologies currently in use including physical/chemical adsorption, pressure swing adsorption, and membrane separation [6][7][8]. Microbial electrochemical technology coupled with anaerobic digestion can further increase methane content in biogas and improve COD degradation efficiency [9,10]. Given the current difficulties in the treatment of industrial potato starch wastewater, this paper aims to further improve the degradation efficiency of potato starch wastewater by coupling microbial electrochemical technology with anaerobic digestion.…”

With the development of the potato starch industry, the output of potato starch wastewater has increased rapidly. In terms of the characteristics of potato industry starch wastewater, it was heavily polluted and difficult to degrade, this paper proposes to use the method of electro-fermentation to efficiently treat potato starch wastewater with high COD concentration to realize resource conversion. Under the constant potential control of -1.0 V, the methane yield was significantly increased (maximum 1254 mL/d), and the cumulative methane production increased by 43%. The COD degradation rate reached 90.56%, an increase of 66.53%. Electro-fermentation can solve the bottleneck of anaerobic digestion and is an emerging technology.

“…In recent years, AD-MEC methane production technology, which couples anaerobic digestion and microbial electrolytic cells, has become a research hotspot [6,7]. Its main advantages include the low cost of microorganisms, abundant sources of electricity and organic matter (carbon source), and mature methane storage and transportation technology [8]. AD-MEC comprises a cathode, anode, electrolyzer, and external circuit.…”

Bioelectrochemical systems are widely used in waste utilization processes. Among them, anaerobic digestion (AD) and microbial electrolytic cell coupling (MEC) are cost-effective and efficient waste-to-energy technologies. In this study, the proposal was made that a carbon felt composite electrode plate be applied to an AD-MEC reactor. The control experiment was conducted using an AD reactor (without the external power supply). The result shows that the carbon felt composite electrode plate increased the biogas production of the AD-MEC reactor by 15.4%, and the average methane content increased by 9.49% compared to the control AD reactor. The total methane production of the AD-MEC reactor and control reactor was 302.51 and 407.79 mL, respectively. The total methane production of the AD-MEC reactor was 34.8% higher than the control group. In addition, the authors found that Methanosarcina and Methanosaeta activities in the AD-MEC reactor were significantly increased. The carbon felt composite electrode plate applied in AD-MEC may have promoted the methanogenic microorganisms’ interspecific acetic acid transport process and increased biogas production and methane content.
