“…As shown in Scheme 1, pine lignin (PL) powders were sieved with ethanol and acetone (polarity: ethanol > acetone) solvents. 29 The isolated lignin samples were then carbonized into a hard carbon material, and used as the anode of sodium-ion batteries. The relationship between the microstructure of lignin-derived hard carbons (LDHCs) and the lignin molecular structure was studied thoroughly.…”

“…17,18 To overcome these limitations, PBAT has been blended with starch and biofillers, including cellulose, lignin, and chitin. 19,20 However, lignin has several limitations including thermal degradability, the tendency to agglomerate within host matrices, and variability in chemical structure depending on the feedstock source. 21 Moreover, PLA/PBAT blends hold promise due to the combination of the mechanical strength of polylactic acid (PLA) and PBAT's toughness.…”

This study presents a technoeconomic analysis (TEA) for a novel ionic polybutylene adipate-co-terephthalate (PBAT), CPBAT, as a paper coating material, showcasing excellent water and oil resistance. This TEA determined total capital investment, operating costs, and minimum selling prices for a production capacity of 1,000 kg of CPBAT per day. The minimum selling prices of CPBAT coated on Kraft paper (CPBAT-K) and CPABT coated on starch-coated Kraft paper (CPBAT-S) are estimated to be $1.327/m 2 and $1.864/m 2 , respectively. Additionally, the results of a sensitivity analysis show that the production of CPBAT-K and CPBAT-S is highly sensitive to the production capacity, raw material costs, energy efficiency of the coating process, reaction energy, and reaction yield. Recovery of the ionization solvent only marginally increases the selling prices of CPBAT-K and CPBAT-S, and hence, it is highly favorable. By increasing production capacity, lowering raw material costs, using energy-efficient coating machines, and partially recovering energy from reactions, the prices of CPBAT-K and CPBAT-S can be reduced to $0.588/m 2 and $0.914/m 2 , respectively. Given that commercial polyethylene-coated paper prices range from $0.94/m 2 to $1.850/m 2 , CPBAT-based coated papers with comparable mechanical and barrier properties along with biodegradability and recyclability are positioned as highly competitive and sustainable alternatives in the market.

Lignin is a natural and nontoxic biomass material. It not only has antibacterial activity but also exhibits antioxidation and UV shielding properties, which has great potential application in food packaging, and the medical fields. However, with the complex structure, the antibacterial efficiency of lignin is quite low. It is therefore necessary to improve the antibacterial performance of lignin to broaden its applications. In this study, LZM hybrid nanoparticles with ZnO, long-chain quaternary ammonium salt structures were prepared by simple self-assembly method. Antibacterial activity and compatibility with PBAT of nanolignin was achieved in one step via surface modification. The antibacterial rates against E. coli and S. aureus of LZM nanoparticles reached up to 100%. Subsequently, LZM hybrid nanoparticles were filled into PBAT by solvent casting to prepare PBAT/LZM composite films, which showed a good compatibility between LZM and PBAT. LZM hybrid nanoparticles exhibit reinforcing and toughening effects on the composites. Especially, the tensile strength of the PBAT-3%LZM composite film is increased from 33.2 to 37.6 MPa. Meanwhile, the bacterial adhesion concentration of PBAT-3%LZM composite to E. coli decreases from 14 × 105 CFU/mL to 6 × 104 CFU/mL, while PBAT-3%LZM no longer adheres to S. aureus. Furthermore, the UV shielding of PBAT-2%LZM at λ = 320 nm is more than 99.0%. These interesting results will support the composite films to be applied in food packaging and medical devices. Hence, LZM has simultaneously LNPs’ antibacterial activity and compatibility with PBAT.
