Green Energy Production and Integrated Treatment of Pharmaceutical Wastewater Using MnCo2O4 Electrode Performance in Microbial Fuel Cell Arul Devi Ettiyan, Tamilarasan Karuppiah, Shabarish Shankaran, Simona Di Fraia Sustainability Switzerland, 2024 The wastewater produced by the pharmaceutical industry is highly organic and toxic. Dual-chambered microbial fuel cells (DMFCs) may represent a sustainable solution to process wastewater while simultaneously recovering its energy content. DMFCs are bio-electrochemical devices that employ microorganisms to transform the chemical energy of organic compounds into electrical energy. This study aims to demonstrate the feasibility of a DMFC with a manganese cobalt oxide-coated activated carbon fiber felt (MnCo2O4-ACFF) electrode to treat pharmaceutical industry wastewater (PW) and exploit its energy content. The proposed technology is experimentally investigated considering the effect of the organic load (OL) on the system performance in terms of organic content removal and electricity production. As per the experimental campaign results, the optimum OL for achieving maximum removal efficiencies for total chemical oxygen demand, soluble oxygen demand, and total suspended solids was found to be 2 g COD/L. At this value of OL, the highest current and power densities of 420 mA/m2 and 348 mW/m2 were obtained. Therefore, based on the outcomes of the experimental campaign, the (MnCo2O4-ACFF) electrode DMFC technique was found to be a sustainable and effective process for the treatment and energy recovery from PW.
Mechanical and Durability Performance of Concrete using Dolomite Powder and Pond Ash as Cement Replacements R. Kavinshankar, K. Tamilarasan, K. Yuvaraj Journal of Environmental Nanotechnology, 2024 The construction sector, reliance on substantial quantities of raw materials has historically imposed a significant environmental burden due to its reliance on cement in concrete production. Cement manufacturing, being energy-intensive, has been a major contributor to CO2 emission, emphasizing the urgent need for sustainable alternatives. This study explored the substitution of cement with industrial by-products such as pond ash (PA) and dolomite powder (DP) to address these challenges. PA was incorporated at an optimal level of 10% by cement mass, while DP was added in varying combination of 5%, 10%, 15%, 20%, 25%, and 30%. Eight mix proportions were formulated for M20-grade concrete, designed with a w/b ratio of 0.5 in adherence to IS:10262-2019. The experimental program assessed the mechanical properties of the mixes, including compressive strength, split tensile strength, and flexural strength, alongside durability characteristics such as Rapid Chloride Permeability Test (RCPT), weathering resistance, and permeability tests. Results demonstrated that the combination of 10% PA and 15% DP (M4 mix) exhibited the most favorable performance at 7, 28, and 90 days, with significant improvements in strength compared to the control mix. The M4 mix displayed enhanced resistance to chloride penetration, superior weathering resilience, and reduced permeability, affirming its effectiveness as a sustainable concrete solution at 7, 28, and 90 days. Overall, the integration of PA and DP in concrete improved strength and reduce the environmental impact of construction materials, offering a promising pathway for eco-friendly and cost-effective building practices.
