Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a reclaimed foam composed by molding a ground foam from a biodegradable polyester. SOLUTION: The foam is molded from a biodegradable and expandable resin composition, ground and molded again, providing the reclaimed foam. Furthermore, a reclaimed molded article is obtained by mixing a ground foam other than polylactic acid in unused polylactic acid-based foamed beads (primary foam) of 70% or more, and by molding them.
