摘要： An embodiment of the present invention provides a biodegradable resin composition containing biomass and a polyhydroxyalkanoate (PHA) resin, a biodegradable film and a mulching film formed using same, and a method for preparing same. A biodegradable resin composition according to an embodiment can enhance tensile strength, elongation, flexibility, and impact resistance of a film formed therefrom by containing the specific components, can be applied to various fields due to biodegradability thereof in both soil and the ocean, and can exert excellent characteristics when usefully applied to, especially, a mulching film.

摘要： The present invention relates to a composition for a biodegradable fiber and a biodegradable fiber manufactured using same. In detail, according to an embodiment of the present invention, the composition for biodegradable fibers contains a polyhydroxyalkanoate (PHA) resin bearing 4-hydroxybutyrate (4-HB) repeating units and specifically a first PHA resin and/or a second PHA resin, each bearing 4-HB repeating units and meets a degradation temperature (Td 5% weight loss) of 220°C or higher as measured by a thermal gravimetric analyzer. Thus, the composition is eco-friendly with excellent biodegradability and biocompatibility and can be used to easily manufacture biodegradable fibers having excellent properties.

摘要： The present disclosure relates to a physically pretreated biomass composition, which enables chemical treatment in a biomass composition comprising a high concentration of a biomass substrate, and a preparation method thereof.
Through specific physical pretreatment (attrition milling) of herbaceous biomass, the physically pretreated biomass composition has fluidity/flowability at a substrate concentration of biomass of 20% (w/w) (biomass:solvent = 1:4) or above, and thus the pretreatment cost may be reduced, and it is very useful in biomass treatment processes.
