Abstract: Provided is a biodegradable polyester polymer comprising a polymerization reaction product of an aliphatic dicarboxylic acid, an C6-30 aromatic dicarboxylic acid, an aliphatic diol, and a branching agent, and wherein the biodegradable polyester polymer has a ratio of z-average molecular weight (Mz) to weight average molecular weight (Mw) (“Mz/Mw”) greater than 2 and an easy-tear film including the same. The biodegradable film has excellent mechanical properties to effectively protect a product inside the packaging but also be easily opened in a controlled manner without excessive force and at the same time, provide an environmentally-friendly alternative to non-degradable plastics.

Abstract: A method according to an embodiment is for recovering a valuable metal from a waste electrode material of a lithium secondary battery by using lithium carbonate. An anode-cathode mixed electrode material that has been separated by draining, crushing, screening, and sorting a waste lithium secondary battery is preprocessed. A precipitation operation performed by adding lithium carbonate (Li2CO3) to a metal melt acquired by performing sulfuric acid dissolution using sulfuric acid. A valuable metal such as nickel, cobalt, manganese, aluminum, and copper is recovered as a residue in the form of a carbonate composite, and a lithium sulfate (Li2SO4) aqueous solution including lithium is recovered as a filtrate.
