Removal of nutrients and bioelectricity generation from institutional wastewater using constructed wetland-microbial fuel cell

This study evaluated the removal of nutrients from institutional wastewater and the generation of bioelectric power using a microcosm-scale constructed wetland system integrated with a microbial fuel cell (CW-MFC). The research explored the impact of vegetation on both bioelectric production and wastewater treatment within the wetland matrix. Results indicated that the CW-MFC system with vegetation outperformed the unplanted system in terms of treatment efficiency. The planted modules achieved average total nitrogen (TN) and total phosphorus (TP) removal efficiencies of 94.6 % and 90.0 %, respectively, compared to 90.59 % and 83.5 % in the unplanted system. Notably, the CW-MFC planted with Scirpus atrovirens exhibited the highest average output voltage (0.648 V) and power density (232 mW/m³). In contrast, the unplanted CW-MFC produced a maximum voltage of 0.537 V and a power density of 220 mW/m³. These findings suggest that Scirpus atrovirens enhances both the treatment efficiency and bioelectricity generation by facilitating microbial activity involved in the biodegradation of organic compounds and improving electron flow from the anode to the cathode. The significant nutrient removal efficiencies and bioelectric power generation demonstrate the potential of using a vegetated CW-MFC system to achieve sustainable wastewater treatment while simultaneously producing renewable energy, thus contributing to more eco-friendly waste management practices

Integrated biorefinery approach for bioconversion of fish manure to volatile fatty acids and its valorization by Schizochytrium sp for docosahexaenoic acid, squalene, and carotenoids production

To meet environmental sustainable goals, an integrated approach was used to generate volatile fatty acids (VFAs) from fish manure through acidogenic fermentation and their valorization by Schizochytrium limacinum SR21 for value-added biomass production. Acidogenic fermentations were conducted at different pH values (5.0–9.0) and total solid (TS) contents (5 %, 8 %, and 12 %). The highest VFA yield from thermally pretreated fish manure was obtained at pH 9.0 and TS 12 %. In batch culture, 84.0 % of the acidogenic fermentation VFAs were utilized by Schizochytrium limacinum SR21. The highest significant biomass, total fatty acids (TFA), and docosahexaenoic acid (DHA) production were 19, 10.1, and 3.0 g/L, respectively, at C/N ratio of 90 in batch culture with yeast extract as a nitrogen source. Analysis of the effects of three nitrogen feeding strategies with simulated VFA in pH-auxostat fed-batch culture shows that DHA concentration of 15.3 g/L and TFA yield of 53.56 g/L were achieved with low nitrogen (10 g/L) feeding. Squalene and carotenoid contents were 85 mg/g and 0.43 mg/g of dry biomass in fed-batch culture. These findings shows that the production of bio-based volatile fatty acids (VFA) is a cost-effective eco-friendly waste management method and provides high-value-added biomass for biofuel and aquaculture feed production.

Towards Sustainable Solid Waste Management Systems: Empirical Evidence From Northern Malawi.

Solid waste management system in Mzuzu City is a growing concern due to its inefficiency and the resulting effect of accumulation of solid waste. In light of this environmental challenge, a study was conducted to assess the system's effectiveness. Through a mixed methods approach and random sampling, 400 respondents from 5 different areas of the city of Mzuzu were selected to provide comprehensive and unbiased responses. It was found that both the public and private sectors lack a complete commitment to sustainable waste management, citing reasons such as limited knowledge on recycling benefits, inadequate infrastructure and budgetary constraints. As a solution, the study proposes a government-led campaign to change attitudes towards waste production and promote recycling. Additionally, a Public-Private Partnership (PPP) should be utilised to develop policies and strategies that encourage private sector involvement in eco-friendly waste management. To further enhance recycling practices, support is needed in transitioning to circular economy waste management practices through regular education and training.

Eco-Friendly Waste Management: A Segregation and Composting System for Domestic Use

Both models are part of the proposed system: The first step is to design a bin that can separate dry and moist trash. Additionally, a composting facility is showcased for the purpose of transforming organic waste into compost. Twenty homes’ worth of garbage was fed into the suggested model, and the results show promise for trash segregation and composting.

Household solid waste management in a recently established municipality of Bangladesh: Prevailing practices, residents’ perceptions, attitude and awareness

Increasing population, economic activities, and the associated factors put a serious strain on municipal solid waste management in developing nations. We assessed the amount of solid waste generated and elucidated the existing management practices at household level in Mymensingh City Corporation, Bangladesh. We also investigated residents’ perceptions and attitudes on waste management and their awareness on waste-induced health and environmental problems. Data were gathered by a questionnaire survey of 352 households and two key informants’ interviews. The Kruskal-Wallis H and Pearson Chi-Squared tests were used for statistical analysis. Results show that a household generated about 0.62 kg of waste per day of which 99% was organic. Following the door-to-door approach, the city corporation collects unsegregated waste. More than 50% of the households reused fresh food waste as green fertilizer, and either reused or sold paper, metal, and plastic waste. Small, higher-income, and educated households generated higher amounts of organic waste than their counterparts. Respondents were satisfied with the existing door-to-door waste collection system, like to use of bioenergy and organic fertilizer, and were willing to pay for sustainable and eco-friendly waste management. More than 80% of respondents were aware of public health and environmental issues caused by waste mismanagement. The corporation has a plan to establish an energy and compost plant for which we suggest providing incentives for source segregation and designated bins to households. The city planners can take the findings of this study as useful baseline information for planning sustainable municipal solid waste management.

Unraveling the challenges of waste-to-energy transition in emerging economies: Implications for sustainability

The recent geopolitical events, such as the conflict between Russia and Ukraine, have strained the available resources worldwide.

Investigation of thermal behaviour and synergistic effect in co-pyrolysis of municipal solid waste and sewage sludge through thermogravimetric analysis

Municipal solid waste (MSW) and sewage sludge (SS) co-pyrolysis have the potential to revolutionize waste management and address energy challenges. Consequently, it is crucial to explore the thermal and synergistic effect of MSW, SS and their blends using thermogravimetric analysis. Different blending ratios (MSW90%SS10 %, MSW80%SS20 % and MSW65%SS35 %) were analyzed under an inert nitrogen (N2) gas atmosphere, at various heating rates (10,20 and 30 K min−1), from 30 °C to 900 °C. This paper specifically addressed the effect of heating rate and blending ratio on separate and jointed pyrolysis of the two raw materials. The analysis revealed two significant decomposition stages observed in the individual pyrolytic processes and their blends. Results showed that a higher heating rate slowed down the decomposition rate due to less effective heat transfer. The blending ratio of 35 % SS at 20 K min−1 exhibited a positive synergistic effect while an antagonistic effect was observed in another mixing ratio. Activation energy determined using the Coats-Redfern model in the second stage of active pyrolysis for MSW90%SS10 %, MSW80%SS20 % and MSW65%SS35 % was 41.879, 43.365 and 40.271 kJ mol−1 respectively. The negative ΔS (entropy) and positive ΔH (enthalpy) values indicated a decrease in disorder and an endothermic reaction respectively. This finding was consistent with the formation of complex products from the feedstock and the endothermic nature of the pyrolysis process. Therefore, strategic co-pyrolysis optimization of MSW and SS with the precise blending ratio of 35 % sewage sludge and controlled heating rate of 20 K min−1, exhibits substantial potential for advancing eco-friendly waste management practices while enabling effective energy recuperation.

Computational insights into deep eutectic solvent design: Modeling interactions and thermodynamic feasibility using choline chloride & glycerol

To address climate change and environmental concerns, the chemical process industries are increasingly adopting green technology and exploring eco-friendly waste management practices. Deep Eutectic Solvents (DES) have emerged as promising green solvents with diverse applications in the industries in separation processes, catalysis, drug design, and a lot more. However, the ideal way for modeling ionic interactions within the hydrogen-bond acceptor (HBA) during DES synthesis remains uncertain, and theoretical insight on the formation mechanism of energetically stable DESs from choline chloride (CHL) and urea (URE) is yet to be explored. In this study, we investigate different modeling approaches (no bond, generic bond, or single bond) for ionic interactions in hydrogen-bond acceptor (HBA) molecules during DES synthesis and the thermodynamic feasibility of forming an energetically stable DES using choline chloride (CHL) and urea (URE) through theoretical calculations (PM3, HF, and DFT). Our findings indicate that the choice of modeling approach does not significantly affect the outcomes across calculation levels. The H-X DES formation pathway emerges as the most viable route for CHL: GLC DES synthesis, offering strong binding energy and high exothermicity. This pathway provides a robust solution for synthesizing energetically stable DES with potential applications in various industries. Researchers can consider alternative calculation levels when DFT becomes cost-prohibitive to optimize computational costs. Our study contributes valuable insights into DES design and synthesis, promoting environmentally sustainable and cost-effective processes.
