The given line graph gives information about the percentage of four distinct substances that were reclaimed in an unspecified nation over a span of 28 years commencing 1982.
From an overall perspective, all the categories underwent an uptrend, with some fluctuations in P&C. Further, it is of note that P&C consistently claimed the top spot whereas P was recycled the least.
Looking at the chart for more details, one can see that a slight climb was witnessed in Paper and cardboard from 1982 to 1986, and this figure was 25% higher than Glass containers at the same time. After a decline to around starting point in 1990, there was a boom in this figure from 1990 to 1994, reaching nearly 80% which outnumbered Glass and containers by 30%, and then it shrank slowly to about 70% in 2010. Glass containers started at around 50% in 1982, after that there was a slight drop to 40% until 1990, but then the period from 1994 to 2006 experienced a gradual growth in Glass containers, reaching over 60% at the end of the perriod.
By comparison, AC and P registered a consistent upswing. Specifically, the percentage of AC which were recycled moderately rose from 5% in 1986 to 25% in 2002. The subsequent 8-year period witnessed a more substantial increase in this figure, reaching 45% at the end of the period. P had the same starting point as AC in 1990, and then there was a slight climb until 1994 to 7%. From that point onwards, it also modestly went up, accounting for one-fifth of AC and it was the bottom-ranker.
