The two pie charts give a breakdown of trash disposal of one country in 1960 and 2011. Overall, paper and food were the two biggest waste, while wood and other trashes were the least in 1960 and 2011 respectively. It is also worth mentioning that food and plastic refuse percentage increased notably, whereas glass and green waste rate showed no change over the past 51 years.
In 1960, the figures for paper and textile waste were the greatest, with the former being 25% and the latter 17%. The percentage of trash of food and other types were same as well as plastic and metal debris, accounting for 12% and 8% in the respective categories. The lowest rates of wasted materials were wood (4%), glass (5%) and green waste (9%).
In 2011, paper and fabric waste percentages decreased, accounting for 15% and 11% respectively. The figures for food rose, contributing to around the quarter of the pie chart (21%), whilst the rate of other types of rubbish declined, amounting to 4%. Plastic and metal debris percentage grew, with plastic waste rate being twice as much as metal waste, resulting in 18% and 9%. The figures for wood waste in 1960 saw a twofold increase by 2011. Interestingly, the percentage of glass and green waste maintained its level.
