Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a biodegradable resin compsn. of which the cost due to a biodegradable resin can be decreased and which can be composted and thus reduced to soil by incorporating a biodegradable resin and food production waste into the same. SOLUTION: An example of the biodegradable resin is a lactic acid-base synthetic resin comprising a ring-opening polymer of lactide. Any food production waste can be used if it is solid, and a typical example is malt lees occurring in producing alcoholic drinks (e.g. beer). The compounding ratio of the waste to the resin is not specifically limited and is pref. determined optimally depending on the purpose of use (the application) of the compsn. Usually 10-200 pts.wt., pref. 50-150 pts.wt., waste is used per 100 pts.wt. resin. The compsn. is molded with extruder or is palletized, and the resultant pelletized compsn. is molded with an extruder, injection molding machine, a compression molding machine, etc.
