The aforementioned line graph delineates the rate of four recycled materials between 1982 and 2010 in a specific country.
Overall, it is discernible that an upward trajectory was generally recorded throughout the period displayed, albeit with some oscillations in both papers & cardboard and Glass containers. Another noteworthy observation is that while paper & cardboard and glass containers held the lion’s share in the recycling rate, aluminium underwent the most robust surge in the displayed period.
Initially, in 1982, paper & cardboard took the lead in the recycling proportion, standing at around 65%, which was 15% higher than that of glass containers. Neither aluminium cans nor plastics barely recorded any major changes. In the 8 ensuing years, there was no shift recorded in paper & cardboard, while a moderate decrease of 10% was registered in the figure of glass containers. The other remaining categories never surpassed 10%.
In 1994, an acceleration of 15% was witnessed in the recycling rate of paper & cardboard, after which point a steep decline of 10% occurred by the conclusion of the period, whereas glass containers bounced back to its starting point, constituting a modest 50%, which eventually rose to 60%. The proportion of aluminum cans recycled accounted for 15% in 1994, followed by a robust increase of 25% at the end of the examined period. In stark contrast, a minor growth was registered in the recycling percentage of plastics, making up for above 10% during the whole displayed period.
