“…However, there is no obvious difference in gas production between adding 0.1 g/L MWCNTs modified CF and adding pristine CF. The total gas production of the high‐loaded MWCNTs (1 g/L) was close to that of the control group, possibly due to the damage caused by the direct contact of cells with MWCNTs [29–30] …”

“…The total gas production of the high-loaded MWCNTs (1 g/L) was close to that of the control group, possibly due to the damage caused by the direct contact of cells with MWCNTs. [29][30] shows the gas production rate in before 20 h, and it can be concluded that the rate of gas production of the CF modified with 0.5 g/L MWCNTs was higher than that of the CF group before 14 h and lower than that of the CF group after 14 h. One reason may be there is no effective connection between the MWCNTs and the CF surface, which leads to the exfoliation and aggregation of MWCNTs. Aggregated carbon nanotubes cannot act as mediators of intercellular electron conduction and may cause damage to cells.…”

Harvesting energy from bubbles produced by seafloor microorganisms to power underwater devices is a promising method. However, the slow gas production rate under natural conditions hinders the practical application of this technology. Herein, we synthesized polyaniline/carboxyl multiwalled carbon nanotube/carbon felt (PANI/c‐MWCNT/CF) by dip‐coating and in‐situ chemical polymerization for accelerating gas production rate from underwater anaerobic digestion. The optimal WNCNTS addition dosage in modified CF was determined to be 0.5 g/L. Compared with the control group, the PANI/c‐MWCNT/CF improved the gas production yield and rate by 48% and 59%, respectively. Furthermore, after seven days of continuous experiments, the high gas production rate was maintained, demonstrating that the PANI/c‐MWCNT/CF is durable and stable. This study supplies enough gas for the underwater bubble energy harvester, removing environmental constraints on subsea in‐situ power generation and opening up a broad prospect for the power supply to underwater equipment.

“…Additionally, AD has shown less influence on air quality than other technologies and is conducive to minimizing carbon emission [41]. Single or mixed organic solid waste can act as a substrate for anaerobic digestion [42,43]; thousands of related studies have been published [44][45][46]. However, it is worth noting that some digestates rich in heavy metals, microplastics (MPs), and antibiotic resistance genes (ARGs) cannot be directly used for agriculture or forestry and should be further disposed of by other methods [47][48][49].…”

Organic solid waste is considered a renewable resource that can be converted by various technologies into valuable products. Conventional thermophilic composting (TC), a well-studied and mature technology, can be applied to organic solid waste treatment to achieve waste reduction, mineralization, and humification simultaneously. However, poor efficiency, a long processing period, as well as low compost quality have always limited its wide application. In order to overcome these shortages, hyperthermophilic composting (HTC) has been recently put forward. This paper reviews the basic principle, process flow, operation parameters, research advances, and application status of HTC. Compared with the TC process, the shorter composting period and higher temperature and treatment efficiency, as well as more desirable compost quality, can be achieved during HTC by inoculating the waste with hyperthermophilic microbes. Additionally, HTC can reduce greenhouse gas emission, increase the removal rate of microplastics and antibiotic residues, and achieve in-situ remediation of heavy metal-polluted soils, which greatly improve its application potential for organic solid waste treatment. This paper also proposes the limitations and future prospects of HTC technology for a wider application. As a result, this review advances our understanding of the HTC process, which promotes its further investigation and application.

“…Crop straw and human-livestock-poultry manure (CSHLPM) are the main waste types used in agricultural production activities. During the development of traditional agriculture for thousands of years, our ancestors also realized the value of CSHLPM as a fertilizer resource [ [1] , [2] , [3] ]. CSHLPM is rich in nutrients, such as N, P 2 O 5 and K 2 O, which are necessary for the growth of various types of crops.…”
