Lignin is an energy-dense, heterogeneous polymer comprised of phenylpropanoid monomers used by plants for structure, water transport, and defense, it the second most abundant biopolymer on Earth after cellulose. In production fuels chemicals from biomass, lignin typically underused as a feedstock burned process heat because its inherent heterogeneity recalcitrance make difficult to selectively valorize. nature, however, some organisms have evolved metabolic pathways that enable utilization...
Biological funneling is used to convert lignin-derived species muconic acid, which separated and catalytically upgraded adipic acid.
Lignin Consolidated Bioprocessing utilizes microbes that simultaneously depolymerize lignin and convert the resulting aromatic compounds to fuel chemical precursors.
This study presents the complete utilization of spent coffee grounds to produce biodiesel, bio-oil, and biochar. Lipids extracted from were converted biodiesel. The neat biodiesel blended (B5 B20) fuel properties evaluated against ASTM EN standards. Although displayed high viscosity, moisture, sulfur, poor oxidative stability, B5 B20 met blend specifications. Slow pyrolysis defatted was performed generate bio-oil biochar as valuable co-products. effect feedstock defatting assessed through...

Hybrid processes, featuring biological conversion of lignocellulose to small molecules followed by chemo-catalytic larger suitable for difficult-to-electrify transport modes, are a promising route biomass-derived fuels in demand climate stabilization.
Summary Microbial conversion offers a promising strategy for overcoming the intrinsic heterogeneity of plant biopolymer, lignin. Soil microbes that natively harbour aromatic‐catabolic pathways are natural choices chassis strains, and Pseudomonas putida KT 2440 has emerged as viable whole‐cell biocatalyst funnelling lignin‐derived compounds to value‐added products, including its native carbon storage product, medium‐chain‐length polyhydroxyalkanoates ( mcl ‐ PHA ). In this work, series...
Significance To meet the growing demand for sustainable aviation fuels (SAF), conversion pathways are needed that leverage wet waste carbon and jet fuel property specifications. Here, we demonstrate SAF production from food waste–derived volatile fatty acids (VFA) by targeting normal paraffins a near-term path to market branched isoparaffins increase renewable content long term. Combining these distinct paraffin structures was shown synergistically improve VFA-SAF flash point viscosity blend...

Acrylonitrile (ACN) is a petroleum-derived compound used in resins, polymers, acrylics, and carbon fiber. We present process for renewable ACN production using 3-hydroxypropionic acid (3-HP), which can be produced microbially from sugars. The achieves molar yields exceeding 90% ethyl 3-hydroxypropanoate (ethyl 3-HP) via dehydration nitrilation with ammonia over an inexpensive titanium dioxide solid catalyst. further describe integrated modeled at scale that based on this chemistry...
Biorefinery process development relies on techno-economic analysis (TEA) to identify primary cost drivers, prioritize research directions, and mitigate technical risk for scale-up through of detailed designs. Here, we conduct TEA a model 2000 dry metric ton-per-day lignocellulosic biorefinery that employs two-step pretreatment enzymatic hydrolysis produce biomass-derived sugars, followed by biological lipid production, recovery, catalytic hydrotreating renewable diesel blendstock (RDB). On...
In this study, we performed a life cycle assessment (LCA) on an emerging lignin upgrading process, namely the production of biobased adipic acid.
Lipids are a promising feedstock to produce renewable hydrocarbon fuels and H2via catalytic hydrothermal processing. Upon exposure media (e.g., 300 °C, 8–11 MPa), lipids rapidly hydrolyze saturated unsaturated free fatty acids in varying ratios, depending on the feedstock, as well glycerol. This report demonstrates potential of Pt–Re/C for conversion hydrocarbons, using glycerol reforming situ H2 production meet process demands. Experiments showed that deoxygenation stearic acid, model was...

cis,cis-Muconic acid is an unsaturated dicarboxylic that can be produced in high yields via biological conversion of sugars and lignin-derived aromatic compounds. Muconic often targeted as intermediate to direct replacement monomers such adipic or terephthalic acid. However, the alkene groups muconic provide incentive for its use polymers, example, synthesis polyester resins. Here, biologically derived incorporated into polyesters condensation polymerization using homologous series...
Lignocellulosic biomass offers a renewable carbon source which can be anaerobically digested to produce short-chain carboxylic acids.
