Summary: The study investigated the effects of temperature and retention time on EFB torrefaction, revealing that higher temperatures and longer retention times led to lower solid yields but higher liquid and gaseous yields. Torrefied EFB showed increased carbon content, decreased oxygen content, improved calorific value, and reduced chlorine content. Thermal degradation of hemicellulose was observed during torrefaction, with oxygen removal migrating to liquid and gaseous products such as water, CO2, CO, and organic compounds. The findings contribute to biomass resource database for future bioenergy applications.

Summary: The study found that a mulching film made of a blend of polyvinyl alcohol and lignin has good water solubility, moisture content, and biodegradability, while effectively preventing weed growth in the soil. Tests on mechanical properties showed that the film with 60% lignin had the highest tensile strength. Life cycle assessment and cost estimation indicated that the blended film had lower environmental impact and was cheaper than commercial mulching films. Therefore, blending polyvinyl alcohol polymer with lignin may be an effective way to improve the biodegradability of mulch films.

Summary: In order to reduce dependence on nonrenewable plastics and solve the problem of non-biodegradable plastic waste, the development of biodegradable plastics from natural resources has received much attention. Starch-based materials, primarily from corn and tapioca, have been extensively studied and produced for commercial use. However, the use of these starches could lead to food security issues. Therefore, the investigation of alternative starch sources, such as agricultural waste, is of great interest. This study examined the properties of films made from pineapple stem starch, which has a high amylose content. The films showed water resistance due to their crystallinity. The effect of glycerol content on mechanical properties and gas transmission rates was also studied. Coatings made from these films were found to slow down the ripening process of bananas and extend their shelf life.

Summary: High planar defect and poor crystalline structure in P3HT hinders the performance of organic photovoltaic devices. This study introduces surface modification using NiCl2 incorporation into P3HT:PC60BM films to improve their structural, electrical, and optical properties. The presence of 20 vol% NiCl2 in the film leads to the formation of longer conjugate P3HT chains, reducing surface roughness and increasing photoabsorbance and electrical conductivity. These findings suggest that NiCl2 can serve as a surface passivator, improving charge transport in P3HT-based organic solar cells.
