Summary: Recently, there has been growing interest in using organic or biodegradable wastes, including lignocellulosic wastes (LWs), as renewable energy sources. Anaerobic digestion (AD) of these wastes can mitigate environmental damage and produce biogas and bioenergy, which is particularly valuable in developing countries. However, there are several challenges to overcome, such as waste floating on top of reactors, high carbon-to-nitrogen ratio (CNR), complex structure of LWs, and poor degradability due to high lignin content. These challenges can be addressed through methods like mixing in reactors, reducing CNR, balancing inoculum-to-substrate ratio (ISR), and pretreatments. This study aims to review the literature on AD of LWs, identify existing challenges, and propose strategies to improve bioenergy production from this waste.

Summary: The nano-metal-treated PET films with anti-virus and anti-fogging ability were developed using sparking nano-metal particles of Ag, Zn, and Ti wires on polyethylene terephthalate (PET) films. A highly transparent, anti-fogging, and anti-virus face shield was prepared using the Zn-PET film. Sparking was an effective technique to prepare the alternative anti-virus and anti-fogging films for medical biomaterial applications.

Summary: Improving biomass production by using low-cost substrates is important for large-scale microalgae production. In this study, the microalga Coelastrella sp. KKU-P1 was cultivated mixotrophically using unhydrolyzed molasses as a carbon source. The optimal conditions for maximizing biomass production were determined, and a batch cultivation achieved the highest biomass production of 3.81 g/L. CO2 supplementation did not improve biomass production, indicating that ambient CO2 concentration was sufficient for mixotrophic growth. The biochemical analysis showed that the microalgal biomass has potential as a source of essential amino acids, pigments, and fatty acids.

Summary: This study investigates the biorefinery of sugarcane bagasse into ethanol and xylitol. The results show that ethanol fermentation of sugarcane bagasse hydrolysate can be carried out without supplementing a nitrogen source, and approximately 50 g/L of bioethanol can be produced after 36 hours of fermentation. The vinasse containing xylose can be successfully used to produce xylitol, and supplementing the vinasse with yeast extract improves xylitol production. Controlled dissolved oxygen and the addition of low fraction of molasses do not positively affect xylitol production.

Summary: The effect of sodium hydroxide concentrations on the morphology, mechanical properties, and water barrier properties of carboxymethyl rice starch films was investigated. Increasing NaOH concentrations resulted in higher degree of substitution of CMSr powders, leading to changes in morphology. The water solubility, elongation at break, and water vapor permeability of the films increased as NaOH concentrations increased, while the water contact angle, melting temperature, and tensile strength decreased.
