PROBLEM TO BE SOLVED : To provide a composition which has an excellent processability unachievable by chemically synthesized aliphatic polyesters or naturally occurring polymers such as starch, is decomposed by the action of microorganisms and the like under an aerobic or an anaerobic environment, when discarded and is derived from plants actively fixing carbon dioxide on the earth and its molding. SOLUTION : The composition comprises wood powder and/or cellulose powder and a microorganism-produced aliphatic polyester copolymer having a repeating unit expressed by formula (1) : [-CHR-CH2-CO-O-] (wherein, R is an alkyl group expressed by CnH2n+1 and n is an integer of 1-3), The composition is used as it is or as a molding.
