Abstract: In the relevant technical field, cellulose-based wastes or agricultural wastes are used as raw materials in the production of environmentally friendly bioplastics or plastic admixture materials. The cost spent on a product is high to recycle agricultural wastes into these said final products. In addition, cellulose-based raw materials such as olive seeds are not as suitable for polymerization as starches. In this context, in the invention, starch-based bread waste is used as a raw material for the production of bioplastics and plastic admixture materials. The bread wastes are more suitable for polymerization, and when used as raw material, the product price per unit time is more economical compared to other agricultural or waste foodstuffs.

Abstract: Disclosed is a biodegradable composition, including: 5 to 90 percent by weight of polylactic acid (PLA), 5 to 80 percent by weight of plant fiber, and 5 to 70 percent by weight of maleic anhydride-grafted polybutylene succinate (PBS-g-MA), acrylic acid-grafted polybutylene succinate (PBS-g-AA), or silane coupling agent-grafted polybutylene succinate (PBS-g-Silane). The article manufactured therefrom is not only biodegradable but also has an enhanced heat deformation temperature, impact resistance and tensile strength. Further, by so limiting the proportion of each component, compatibility between the components may be increased and crystallization of polylactic acid may be facilitated.

Abstract: A biodegradable straw, which includes: a plant acid-modified plant fiber material, accounting for 20 wt % to 70 wt % of a total weight of the biodegradable straw; and a PBS material, accounting for 30 wt % to 80 wt % of the total weight of the biodegradable straw; wherein the plant acid-modified plant fiber material is mixed with the PBS material and then extruded and molded into the biodegradable straw. The biodegradable plant fiber and PBS material serve as raw materials for the straw, and the plant fiber is transformed with plant acid to improve the natural decomposition efficiency of the biodegradable straw in the environment, reduce environmental pollution, meet the demands of environmental protection, and improve the food safety of the biodegradable straw. It also improves the economic benefit of the biodegradable straw and reduces the production cost.
