Anaerobic Digestion of Dye Wastewater and Agricultural Waste with Bio-Energy and Biochar Recovery: A Techno-Economic and Sustainable Approach

Water, Journal Year: 2024, Volume and Issue: 16(14), P. 2025 - 2025

Published: July 17, 2024

While several researchers have investigated the anaerobic digestion (AD) of textile wastewater for dye degradation, their studies suffer from lower biogas productivity due to substrate inhibition and occurrence secondary pollution digestate disposal. Hence, this study focuses on using extract wheat straw (WS) as a co-substrate facilitate AD process, followed by recycling sludge biochar production. In first study, batch digesters were operated at different (DW)/WS ratios (0–50% v/v), substrate-to-inoculum ratio 0.28–0.50 g/g, pH 7.0 ± 0.2, 37 °C. The digester DW/WS fraction 65/35% (v/v) showed best chemical oxygen demand (COD) removal efficiency 68.52 3.40% with bio-CH4 270.52 19.14 mL/g CODremoved. About 52.96 3.61% initial COD mass was converted CH4, avoiding caused volatile fatty acid (VFA) accumulation. second experiment, dry thermally treated 550 °C 2 h under an oxygen-deprived condition, yielding 0.613 0.031 g biochar/g. This exhibited multiple functional groups, mineral contents, high stability (O/C = 0.193). combined digestion/pyrolysis scenario treating 35 m3/d (106.75 kg COD/d) could maintain profits reduction, biogas, biochar, carbon trading, obtaining 6.5-year payback period.

Zero-Valent Iron and Activated Carbon Coupled to Enhance Anaerobic Digestion of Food Waste: Alleviating Acid Inhibition at High Loads

Fermentation, Journal Year: 2023, Volume and Issue: 9(9), P. 818 - 818

Published: Sept. 7, 2023

Anaerobic digestion (AD) has the advantages of utilizing complex substrates and producing renewable energy is currently one mainstream technologies for food waste (FW) resourcing. However, at high organic loads low inoculum-to-substrate ratios (ISRs), AD with FW as substrate prone to acid accumulation, resulting in a drastic decrease gas production system collapse. This study investigated effect coupled addition zero-valent iron (ZVI) activated carbon (AC) on three ISRs 0.715, 0.625, 0.5. The results showed that control group acidified stopped biogas when ISR decreased 0.625 0.5, but ZVI AC alleviated acidification increased cumulative yield. Especially = yield + was 31.5%, 99.5%, 11.43 times higher than ZVI, AC, groups, respectively. also degradation volatile fatty acids (70.5–84.4%) soluble chemical oxygen demand (50.0–72.9%) while decreasing propionate concentration improving stability system. COD mass balance analyses indicated promoted conversion particulate matter sources methane.

Solid Waste Management and Sustainability in Deltas: Concluding Remarks and Outlook

Published: Jan. 1, 2024

While Deltas represent about 5% of the global land surface, they occupy over 550 million people (i.e., a high population density). The Delta area, which is characterized by flat topography, fertile alluvial soils, and abundant natural resources, vital for human habitation. However, this area subjected to diverse anthropogenic threats, owing climate change vulnerability. delicate equilibrium delta ecosystems threatened as activities escalate (e.g., illegal solid-waste dumping), necessitating innovative solutions. This chapter includes main concluding remarks on evolution waste management practices within Deltas, emphasizing significance sustainable approaches balance ecological socio-economic aspects. As continue confront dynamic seasonal challenges, book tends provide foundation promoting resilient in solid (SWM) these ecosystems.
