Abstract: A biodegradable BB pellet includes an organic material and an inorganic material. Therein, the organic material includes a main ingredient polybutylene-1,4-succinate, while the inorganic material is selected from pulvis talci powder, calcium carbonate, barium sulfate, mica powder, and zinc powder. The manufacturing method of the present invention is mixing the organic material and the inorganic material into a mixture, and processing the mixture orderly through injection molding, grinding, waxing and polishing. Thereby, the present invention is degradable by the environment and prevented from polluting environment. Also, due to the properties of better toughness, flexibility, and higher heat tolerance, the present invention is prevented from bursting to hurt other people and deforming during long-distance transportation.

Abstract: A biodegradable composition includes: a polymer component including a first polymer of polybutylene-1,4-succinate (PBS); and a cross-linking agent capable of producing a free radical to allow the polymer component to be subjected to a free radical cross-linking reaction in such a condition that the biodegradable composition has a melt index ranging from 1.5 to 3.0.

Abstract: An article includes: a biodegradable textile material which includes a liquid absorbent layer made of a fiber material selected from rayon, cotton, linen, and synthetic fibers; and a liquid-impermeable layer bonded to the liquid absorbent layer, and made from a biodegradable composition including polybutylene succinate as a major component.
