As a biomass-derived polymer containing abundant aromatic units, lignin has emerged as a prime candidate for replacing fossil fuels owing to its renewable nature. Paradoxically, as synthetic polymer materials with aromatic structures similar to those of lignin, plastics have become a critical environmental challenge owing to their accumulation over recent decades. The inherent stabilities of lignin and plastics pose significant challenges for their efficient utilization and recycling, making catalytic depolymerization a focal research point in recent years. Innovative catalytic strategies that enable the high-yield production of aromatic compounds through the catalytic hydroprocessing of lignin and plastic waste have recently emerged. These methods offer opportunities for the conversion of recalcitrant polymers into valuable chemicals and sustainable fuels. This paper comprehensively reviews these advancements and emphasizes their potential applications in catalytic hydroprocessing for biofuel production. Additionally, it highlights the latest developments in the high-value upgrading of lignin derivatives and underscores their significance in building a sustainable chemical industry. The review examines the entire value chain from lignin and plastic depolymerization to the production of high-value chemicals to outline the potential for enhancing the efficiency of sustainable processes. This emphasizes the critical role of developing novel cost-effective methodologies for the catalytic depolymerization of lignin and plastic waste. These advancements are expected to play a pivotal role in fostering a sustainable economy and addressing pressing environmental challenges.</div></div>","PeriodicalId":100595,"journal":{"name":"Green Carbon","volume":"3 4","pages":"Pages 335-362"},"PeriodicalIF":0.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145801996","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, current life cycle assessments (LCA) of chemicals are limited by slow speed and high cost. Molecular-structure-based machine learning (ML) is the most promising technology for the rapid prediction of life-cycle environmental impacts of chemicals. Advances in training datasets, feature engineering, and model architectures for ML models in this area are systematically discussed in this review. We call for the establishment of a large, open, and transparent LCA database for chemicals that includes a wider range of chemical types to address the challenge of data shortages. Greater emphasis on external regulation of data is also needed to produce high-quality LCA data. The construction of more efficient chemical-related descriptors and the identification of features most pertinent to LCA results represent pivotal steps in the advancement of next-generation modeling. The integration of large language models (LLMs) is expected to provide new impetus for database building and feature engineering. Finally, expanding the dimensions of predictable chemical life cycles can further extend the applicability of relevant research.

One of the current chemical processes used to produce <em>S</em>-PGB involves the Hofmann rearrangement of (<em>R</em>)-3-isobutyl glutaric acid monoamide (<em>R</em>-IBM). However, the chemical resolution of <em>R</em>-IBM is inefficient and environmentally unsustainable. In this study, we established an enzyme-catalyzed route to <em>R</em>-IBM that proceeds with exceptional optical purity and yield. We successfully resculpted the substrate-binding pocket of <span>d-</span>hydantoinase by attenuating the steric hindrance and enhancing hydrophilicity, resulting in accelerated substrate transport and restricted side-chain rotation during the asymmetric hydrolysis process. Notably, both optical purity and yield for the generation of <em>R</em>-IBM from the prochiral substrate 3-isobutyl glutarimide (IBI) were enhanced for the M3 (L64A/F66H/C318T) mutant; the enantiomeric excess increased from 65.51 % ± 5.85 % to 98.62 %± 0.28 % (ee<sub>p</sub>) and <em>k</em><sub>cat</sub>/<em>K</em><sub>m</sub> increased from 14.92 to 207.06 s<sup>−1</sup>∙M<sup>−1</sup>. The ancestral sequence reconstruction (ASR) and consensus analyses guided further engineering of the flexible C-terminal region of <span>d-</span>hydantoinase to enhance the thermostability of the enzyme. The final mutant, M6 (L64A/F66H/C318T/R99G/A265P/G466N/E470A), demonstrated a remarkable improvement in <em>R</em>-IBM production efficiency; thus, 500 mM IBI was completely transformed into <em>R</em>-IBM in 24 h.

Herein, we report a novel one-pot, two-step process for the highly efficient synthesis of ADA from the biomass derivative 2-furoic acid <em>via</em> hydrogenative carbonylation. In the first step, 2-furoic acid is selectively reduced to 2-tetrahydrofuroic acid using a Rh catalyst with acetic acid (AcOH) and water (H<sub>2</sub>O) as solvents. Subsequently, within the same catalytic system, the addition of I<sub>2</sub> as a promoter enables the further conversion of 2-tetrahydrofuroic acid to ADA through a highly selective carbonylation reaction under CO and H<sub>2</sub> atmospheres. This one-pot, two-step process achieved an ADA yield of 91.4 % from 2-furoic acid. Mechanistic studies revealed that 5-iodopentanoic acid is the key intermediate in the carbonylation process.
