The increasing demand for renewable energy sources has led to significant interest in second-generation biofuels derived from lignocellulosic biomass and waste materials. This review underscores the pivotal role of valorization meeting global needs, mitigating greenhouse gas emissions, fostering a circular bioeconomy. Key pretreatment methods—including steam explosion, pressure treatment, chemical pretreatment—are analyzed their ability enhance accessibility cellulose hemicellulose enzymatic saccharification. Advances cellulolytic enzyme development fermentation strategies, such as use genetically engineered microorganisms capable fermenting both hexoses pentoses, are discussed detail. Furthermore, potential biorefinery systems is explored, highlighting capacity integrate into biofuel production alongside high-value bioproducts. Case studies recent trends bioethanol biogas examined, providing insights current state research its industrial applications. While hold considerable promise sustainable emissions reduction, challenges related cost optimization, process scalability, technological barriers must be addressed enable large-scale implementation. serves comprehensive foundation bridging gap between laboratory application, emphasizing need continued innovation interdisciplinary collaboration technologies.

The sustainable utilization of biomass-derived bioactives addresses the growing demand for natural health products and supports development goals by reducing reliance on synthetic chemicals in healthcare. Cannabis sativa biomass, particular, has emerged as a valuable resource within this context. This study focuses hydroethanolic extract C. leaves (CSE), which exhibited significant levels phenolic compounds contributing to robust antioxidant activity. Evaluation using potassium ferricyanide, ABTS, DPPH methods revealed potent radical scavenging activity comparable Trolox standard. UPLC-MS/MS profiling identified cannabinoids predominant secondary metabolites CSE, with flavonoids also present substantial quantities. investigated anti-inflammatory potential CSE RAW 264.7 macrophages IL-1β-stimulated C-20/A4 immortalized human chondrocytes, demonstrating protective effects without cytotoxic or mutagenic effects. Mechanistically, reduced inflammation inhibiting MAPK NF-κB signaling pathways. In silico approaches showed ability CSE's main bind influence activity, confirming vitro evidence. Incorporating leaf into hyaluronic acid-based formulation biotechnological promise treating joint inflammation. Future research should aim elucidate molecular mechanisms underlying these explore CSE-derived mitigating osteoarthritis progression. approach highlights significance utilizing annually increasing biomass waste bioactivity environmental impact reduction.

Pyrolysis of lignocellulosic biomass and waste plastics has been intensely studied in the last few decades to obtain renewable fuels chemicals. Various pyrolysis devices have developed for use a laboratory setting, operated either batch or continuously at scales ranging from milligrams per hour tenths g hour. We report here design operation novel staged free-fall (catalytic) unit demonstrate that concept works very well pinewood sawdust, paper sludge, polypropylene as representative feeds. The consists vertical tube with pretreatment section, solid residue collection gas–liquid separation/collection catalytic reaction section optionally perform ex situ upgrading vapor. sample is placed tube, which transported by gravity through various sections unit. It allows rapid testing semicontinuous feeding (e.g., 50 h–1) opportunity reactions under an (inert) gas N2) atmospheric elevated pressure bar). Liquid yields noncatalytic sawdust optimized conditions (475 °C pressure) were 63 wt % on intake. A lower yield 51 (on basis) was obtained likely due presence minerals CaCO3) feed. possibility using (pyrolysis 475 550 °C) also successfully demonstrated sludge feed H-ZSM-5 catalyst (21 biomass).
