Abstract Unprecedented efforts are being deployed to develop hydrogen production from bioresources in a circular economy approach, yet their implementation remains scarce. Today’s Challenges associated with the shortage value chain, lack of large-scale infrastructure, high costs, and low efficiency current solutions. Herein, we report route cellulose pulp, integrating biomass fractionation gasification biorefinery approach. Softwood sawdust undergoes formic acid organosolv treatment extract cellulose, followed by steam gasification. High-purity hydrogen-rich syngas at concentration 56.3 vol% yield 40 g H2 /kg was produced. Char offers advantage producing free-tar reducing cleaning costs mitigating downstream issues. A comprehensive assessment mass energy balance along chain revealed an 26.5% for production, requirement 111.1 kWh/kg . Optimizing solvent recovery valorization other constituents as added-value products approach would further improve process entice its industrial takeoff.

Scientists are of key importance to the society advocate awareness climate crisis and its underlying scientific evidence provide solutions for a sustainable future. As much as research has led great achievements benefits, traditional laboratory practices come with unintended environmental consequences. Scientists, while providing problems educating young innovators future, also part problem: excessive energy consumption, (hazardous) waste generation, resource depletion. Through their own operations, science, laboratories have significant carbon footprint contribute crisis. Climate change requires rapid response across all sectors society, modeled by inspiring leaders. A broader community that takes concrete actions would serve an important step in convincing general public similar actions. Over past years, grassroots movements sciences recognized overlooked impact enterprise, so-called Green Lab initiatives emerged seeking address research.

It is essential to develop sustainable approaches creating energy devices by using natural materials like lignocellulosic biomass. As lignin mostly abundant in nature serves as a tribo-positive filler due chemical morphology. Here in, we isolated of from the raw hardwood via soda pulping method and utilize developing composite nanofibers with polyvinylidene fluoride (PVDF), i.e., PVDF-Lignin Nanofiber (PLNF) an electrospinning technique. Triboelectric characteristics different concentration were evaluated against polytetrafluorethylene (PTFE). An enhancement output performance was observed compare PVDF. The electrical PLNFs TENGs depends on their structural features, polarizability, dielectric properties, force, frequency vibration. Thus, P10-L5 TENG (PVDF 10 wt% 5% Lignin) generates highest power density approximately ~60 mWm-2. high attributed uniform dimensions surface charge accumulation PLNF. lignin-based have exhibited impressive stability endurance, enduring 10,000 cycles at 1 Hz, 3 5 Hz frequencies. produced high-power output, while ITO-PET sheets provided strength flexibility, resulting stable, durable system.
