The given pie charts illustrate the proportion of different types of waste generated in a European country in 2000 and 2020. According to the data, the waste is categorized into six types: organic, plastic, metal, paper, glass, and other waste.
Overall, organic waste accounted for the largest share in both years, although its proportion declined slightly over time. In contrast, paper waste saw a significant increase, while metal and plastic waste experienced a decline. Interestingly, the proportion of glass and other waste remained unchanged throughout the period.
Organic waste accounted for the largest share of total waste in 2000 at 35%, but it dropped to 30% in 2020. Similarly, plastic waste declined noticeably from 25% to 20%, making it the second-largest decrease after metal waste. By contrast, metal waste saw a sharp drop from 15% to 10%, indicating a possible shift towards alternative materials. Notably, the smallest proportion was other waste, which remained constant at 5% over the years.
A striking feature of the data is the growth in paper waste, which rose significantly from 10% to 25%, making it one of the most substantial changes. Meanwhile, the proportion of glass waste remained stable at 10% in both years. It is worth noting that this stability contrasts with the declining trends of plastic and metal waste. To sum up, the data suggests a shift towards more paper-based materials, possibly due to environmental policies, while the reliance on plastic and metal has gradually decreased.
