“…The highest daily average voltage generated in in this study was 650 mV when the biochar concentration reached 500 mg/L in the MFC, which was comparable to previous reports about the electricity produced from swine wastewater in MFCs (Min et al, 2005). Any improvement in electricity generation in the MFC with the presence of biochar might be due to biofilm formation on the surface of biochar and the increase in conductivity of electrodes' surfaces in the MFC (Ayyappan et al, 2018;Hejazi et al, 2019).…”

“…The authors applied this chemo-bio route for the dechlorination of trichloroethylene. A similar approach was used by Ayyappan et al [186], who used a coconut shell biochar for dye degradation in a microbial fuel cell; they claimed a removal efficiency of up to 78 wt.%.…”

Biochar is the solid residue that is recovered after the thermal cracking of biomasses in an oxygen-free atmosphere. Biochar has been used for many years as a soil amendment and in general soil applications. Nonetheless, biochar is far more than a mere soil amendment. In this review, we report all the non-soil applications of biochar including environmental remediation, energy storage, composites, and catalyst production. We provide a general overview of the recent uses of biochar in material science, thus presenting this cheap and waste-derived material as a high value-added and carbonaceous source.

“…In the realm of MFC applications, a study explored bioenergy generation and dye decolourization from dye wastewater, showcasing a power density of 940.61 ± 5 mW/m 2 , a voltage output of 790 ± 5 mV, and 83% decolourization. MFCs provide multiple benefits, including waste management, electricity generation, and reduced sludge production [54]. Combining biological catalytic activity with conventional electrochemical reactions, MFCs have proven efficient in decolourizing azo dyes and producing bioelectricity.…”

Synthetic dyes, exceeding 100,000 types on the market and produced at a global scale of over 700,000 tons annually, are extensively used in the textile industry. This industry, a leading contributor to water contamination, relies on dyes like reactive, azo, anthraquinone, and triphenylmethane, resulting in substantial water usage and significant effluent generation. A significant modern challenge is the pollution caused by dye-mixed wastewater, releasing hazardous chemicals into water bodies and posing threats to ecosystems, plants, and human health. Traditionally, physicochemical techniques have addressed textile dye-containing wastewater, but their drawbacks, including cost, inefficiency, and potential secondary pollution, have steered attention towards biological alternatives. Utilizing microorganisms and enzymes, these biological methods, such as microbial cell enzyme immobilization, the biofilm technique, bioreactors, biofuel/bioelectricity production, and genetic engineering, have emerged as promising, cost-effective, and environmentally friendly solutions for efficient dye removal from wastewater. This review paper specifically highlights advanced biological techniques and emphasizes their efficacy in addressing the challenges posed by synthetic textile dyes. Through a systematic review of recent research papers, published results, and observations, this review paper provides insights into emerging biological treatment strategies for effectively removing synthetic textile dyes and contaminants from wastewater.
