Traditionally relegated to landfills or incineration, biowaste is increasingly recognized as a renewable resource for producing biofuels, biochemicals, biomaterials, and animal feed. This review offers a systems-level analysis of biowaste characteristics, conversion processes, and derived bioenergy products such as biofuels, biogas, biodiesel, biohydrogen, bioelectricity, and other valuable chemicals. Diverse conversion methods are explored, including anaerobic digestion, fermentation, microbial fuel cells, pyrolysis, and gasification, alongside conventional practices like landfilling and incineration. Emerging analytical advancements are revolutionizing biowaste valorization. Artificial intelligence (AI) and machine learning (ML) techniques are highlighted for their transformative impact. For example, AI-driven optimization of pyrolysis conditions has enhanced biochar yield and quality, while predictive modeling using neural networks has improved the efficiency of anaerobic digestion. Additionally, techno-economic analysis (TEA) demonstrates a significant reduction in operational costs through AI-driven process optimization, and life cycle assessment (LCA) quantifies reductions in environmental impacts, such as greenhouse gas emissions and energy consumption, due to AI-informed process adjustments. Advanced assessment tools, including material flow analysis (MFA), further evaluate resource dynamics within biowaste-to-energy systems. Artificial intelligence and ML optimize waste processing, improving efficiency and product quality. Key analytical tools like TEA, LCA, and MFA assess the financial and environmental viability of these processes.</div></div>","PeriodicalId":15759,"journal":{"name":"Journal of Environmental Chemical Engineering","volume":"13 3","pages":"Article 116673"},"PeriodicalIF":7.4,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143873679","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many of these enzymes rely stoichiometrically on the NADH cofactor to provide the necessary reducing equivalents. However, the high cost and significant demand for the cofactor hinder the industrial feasibility of this method. NADH regeneration allows for the recycling of NADH at catalytic concentrations, thereby eliminating the stoichiometric requirement. Consequently, biocatalytic CO₂ reduction should be viewed as a two-part cooperative process involving an NADH regenerating unit and an enzymatic CO₂ reducing unit. This comprehensive review outlines the concepts and mechanisms underlying NADH regeneration and CO₂ reduction. In the first part of the review, various methods of NADH regeneration and related research are discussed. The second part addresses the basic concepts regarding enzymatic CO₂ reduction, followed by a review of research on CO₂ reduction coupled with NADH regeneration. This includes a review of single and multi-enzyme cascade systems for the production of primarily three products: formate, formaldehyde, and methanol. Various strategies to maximize the synergy between the two units and maintain their stability, such as compartmentalization, immobilization, and encapsulation of the multiple reaction partners, are examined. Toward the end, nature-inspired artificial photosynthetic systems are discussed. These systems facilitate the conversion of solar energy into fuels through CO₂ reduction, the carbon source, and water splitting, the electron source. This review highlights the advancements and challenges in the field of biocatalyzed CO₂ reduction, particularly concerning hybrid cofactor utilization systems.</div></div>","PeriodicalId":15759,"journal":{"name":"Journal of Environmental Chemical Engineering","volume":"13 3","pages":"Article 116657"},"PeriodicalIF":7.4,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143844312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hence, an effective treatment is imperative before being discharged into the environment. To ensure an appropriate treatment, a thorough comprehension of LFL physico-chemical properties is essential. In addition to conventional contaminants such as chemical oxygen demand, biochemical oxygen demand, solids, ammonia, metals, recent studies have reported the presence of dissolved organic matter (DOM) and emerging contaminants such as bisphenols, PFAS, xenobiotics in trace concentrations. While conventional detection techniques are chemical and time consuming and reveal limited information regarding DOM, spectroscopic techniques such as UV–visible spectroscopy, Fourier-transform ion cyclotron resonance mass spectrometry, excitation emission matrix fluorescence spectroscopy are comparably more efficient, and effective. Furthermore, the conventional MBR has shown lower efficiency for treating old LFL and removal of heavy metals, phosphorus, micropollutants and recalcitrant. However, novel configurations in MBR such as high-retention MBRs (nanofiltration-MBR, osmotic MBR, and membrane distillation bioreactor), and electrochemical MBR are more effective alternatives with excellent removal efficiencies of micropollutants, and pharmaceuticals. One of the major limitations in MBR is membrane fouling which reduces the lifetime of membrane and in turn increases the operational cost of MBRs. Novel strategies such as electrically or mechanically assisted scouring, chemical cleaning, enzymatic treatment and the development of novel nanomaterial-based membranes have been proposed to mitigate membrane fouling in MBRs. Further, it is essential to decipher the microbial dynamics in MBR which facilitates contaminant removal by using genome sequencing tools and understand the economic and environmental aspects of MBR.</div></div>","PeriodicalId":15759,"journal":{"name":"Journal of Environmental Chemical Engineering","volume":"13 3","pages":"Article 116653"},"PeriodicalIF":7.4,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143829605","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review explores a wide range of remediation approaches using biocompatible materials, including natural-based polymers, biochar, plant-derived substances, microorganism-derived systems, and protein coronas. Among these materials, natural-based polymers (e.g., chitosan, alginate) effectively adsorb M/NPs via electrostatic interactions and gel encapsulation. Similarly, biochar, due to its highly porous structure, enhances pollutant sequestration, particularly in aquatic systems. Plant-derived substances, including cellulose nanofibrils (CNF), sponges, and aquatic plants, offer promising nature-inspired solutions for M/NP remediation. Microorganism-derived systems facilitate M/NP degradation through enzymatic hydrolysis, biofilm formation, and trapping, while protein coronas influence particle aggregation and sedimentation, improving removal efficiency. The aim of this study is to review a wide range of biocompatible materials for the removal of M/NPs from contaminated environments.
