The pie charts illustrate 8 types of waste disposal, paper, green waste, metal, glass, plastic, wood, food and textiles, in a country in two different years, 1960 and 2011
Overall, it is evident that while recyclable wastes were prominent in 1960, non-environmentally friendly ones were significantly dominant in 2011. Additionally, while only paper waste had a figure above 20% in 1960, food was the only category having that figure in 2011.
In terms of recyclable materials, paper accounted for the highest waste disposal, about 25% in 1960. This figure was followed by textiles, sharing about 17% in the same year. However, both figures exhibited a noticeable decline in 2011, 11% for textiles and 15% for paper, a decrease of 6% and 10%, correspondingly. Conversely, green waste remained unchanged in both years, accounting for 9%, while wood’s figure doubled in 2011 compared to itself in 1960, from 4% to 8%.
As for non-environmentally friendly wastes, plastic and metal shared the same figure in 1960, about 8%. Metal experienced a negligible increase, about 1%, whereas the consumption of plastic rose dramatically, leading to an increase of 10% in 2011. Moreover, food waste increased by 9% in 2011 compared to itself in 1960, about 12%. Glass exhibited the same level of waste in both years, sharing about 5% of waste disposal.
