A detailed research for the article composition of domestic wastes was carried out in Kyoto city. The results show that 60% of domestic wastes by volume are composed of packaging materials and food packaging occupises 65% of those. About 70% of packaging materials in domestic wastes are made of plastic or paper. A recent trend on the consumption of packaging is estimated from various forwading statics. An undesirable change in food packaging having a great influence on the treatment of domestic wastes is discussed. This paper proposes a new evaluation method in which characteristics of refuse are evaluated by the volumetric analysis.
