Abstract Biochar (BC) was prepared by carbonizing sludge from agricultural lignocellulosic waste fermentation and then used to adsorb lambda‐cyhalothrin (LM), malathion (MA), oxamyl (OX) as potential pesticides in agrochemical industrial wastewater. Additionally, the photodegradation performance of ZnO ZnO/Fe evaluated using various catalyst doses a constructed parabolic solar collector reactor. The optimal dose reaction time 1.0 g/L 135 min. OX, MA, LM removal increased 38%, 30%, 24% pristine 55%, 70%, 46.9% case addition BC with (ZnO/BC), respectively. doping iron did not improve efficiency due reduction crystallinity affinity towards pollutants after introducing those ions. mechanism degradation proposed, by‐products generated were identified. total cost estimated for pure ZnO, iron‐doped (ZnO/Fe/BC). highest binding energy −44.74 recorded BC–OX complex, followed BC–LM at −42.97. adsorption LM, OX ZnO/BC is primarily hydrophobic interaction, hydrogen bonding, π–π interaction. After three cycles recycling ZnO/BC, remained 55–52.5% 70–65% 46.9–42.8% indicating excellent reusability stability composite catalyst. low solar‐light‐driven process may technique's feasibility large‐scale implementation.

Abstract The development and recycling of biomass production can partly solve issues energy, climate change, population growth, food feed shortages, environmental pollution. For instance, the use seaweeds as feedstocks reduce our reliance on fossil fuel resources, ensure synthesis cost-effective eco-friendly products biofuels, develop sustainable biorefinery processes. Nonetheless, in several biorefineries is still infancy stage compared to terrestrial plants-based lignocellulosic biomass. Therefore, here we review seaweed with focus production, economical benefits, feedstock for anaerobic digestion, biochar, bioplastics, crop health, food, livestock feed, pharmaceuticals cosmetics. Globally, could sequester between 61 268 megatonnes carbon per year, an average 173 megatonnes. Nearly 90% sequestered by exporting deep water, while remaining 10% buried coastal sediments. 500 gigatonnes replace nearly 40% current soy protein production. Seaweeds contain valuable bioactive molecules that be applied antimicrobial, antioxidant, antiviral, antifungal, anticancer, contraceptive, anti-inflammatory, anti-coagulants, other cosmetics skincare products.

This review article provides useful information on TiO2 and ZnO photocatalysts their derivatives in removing organic contaminants such as dyes, hydrocarbons, pesticides, etc. Also, the reaction mechanisms of were investigated. In addition, impact adding metallic (e.g., Ag, Co, Pt, Pd, Cu, Au, Ni) non-metallic C, N, O, S) cocatalysts to structure photodegradation efficiency compounds was thoroughly studied. Moreover, advantages disadvantages various synthesis procedures nanocatalysts discussed compared. Furthermore, photocatalyst dosage, structure, contaminant concentration, pH, light intensity wavelength, temperature, time According previous studies, led a remarkable enhancement stability reusability. attached demonstrated photocatalytic contaminants.

Herein, we explore the holistic integration of magnetite-based photocatalysts and techno-economic analysis (TEA) as a sustainable approach in wastewater treatment aligned with Sustainable Development Goals (SDGs). While considerable attention has been devoted to photocatalytic dye degradation, nexus between these processes considerations remains relatively unexplored. The review comprehensively examines fundamental characteristics photocatalysts, encompassing synthesis methods, composition, unique properties. It investigates their efficacy addressing homogeneous heterogeneous aspects while discussing strategies optimize photodegradation efficiency, including curbing electron-hole recombination mitigating scavenging effects interference by ions humic acid. Moreover, management are examined, focusing on reusability regeneration post-dye removal, along potential for reusing treated relevant industrial applications. From perspective, study evaluates financial feasibility deploying treatment, correlating reduced pollution marketing water social, economic, environmental objectives. By advocating TEA, this paper contributes insights into scalable profitable practices. underscores alignment practices SDGs, emphasizing comprehensive managing ways that meet environmental, societal

Contamination of water by ciprofloxacin has become a significant concern due to its adverse health effects and growing evidence antimicrobial-resistant gene evolution. To this end, chemically modified bamboo biochar was prepared from sawdust effectively remove (CIP) an aqueous solution. Under similar adsorption conditions, the (MBC) excellent CIP removal efficiency (96%) compared unmodified (UBC) (45%). Thus, MBC used in batch experiments, process optimized with central composite design (CCD) framework response surface methodology (RSM). Sorption parameters such as initial concentration, pH, adsorbent dose, contact time were studied found have effect on removal. The optimal obtained at dose (0.5 g L -1 ), concentration (20 mg pH (7.5), (46 min). kinetic data well described pseudo-second-order model ([Formula: see text]), both Langmuir text]) Freundlich models gave best fit isotherm analysis. maximum monolayer capacity 78.43 based model. These results suggest that mainly controlled chemisorption. Moreover, endothermic spontaneous. Overall, is low-cost, efficient, recyclable for eliminating emerging contaminants
