The pie charts illustrate the proportions of different types of waste disposed of in one country in 1960 and 2011.
Overall, paper accounted for the largest share of waste in both years. Over the period, the proportion of plastic increased noticeably, while several traditional materials, such as glass and textiles, became less significant.
In 1960, paper made up the biggest portion of waste at about a quarter of the total. Glass was the second largest category, representing just under one fifth. Food waste accounted for approximately 12%, while green waste and textiles each contributed around 8-9%. Smaller amounts were recorded for plastic, wood and metal, all of which together made up a relatively minor share.
By 2011, paper still remained the dominant waste type, although its proportion fell slightly. Plastic waste rose substantially and became one of the more prominent categories. In contrast, the shares of glass, textiles and food waste declined compared to 1960. Green waste and metal showed moderate changes, while wood continued to represent a relatively small proportion overall.
