Abstract
Various socioeconomic factors and the level of industrialization are considered in forecasting the volumes and composition of solid waste generated in 28 cities worldwide. Multiple linear regression analysis of the effect of these factors on the paper, metal, food, and glass recovery components of waste indicates that the persons per dwelling, climate, and income are the most important factors influencing the percentages of the four components. The percentage of paper in waste is directly related to and is affected by income levels. Food and glass components in waste are most affected by the dwelling occupancy rate.
