The chart illustrates the recycling percentage of four different materials(paper and cardboard, glass containers, aluminium cans and plastics) in a period between 1982 to 2010, with data provided for one particular country.
Overall, all materials were recycled more by the end of the period, but the patern divide them into two groups. While plastics and aluminium cans didn’t have any declines over the period, glass containers and paper materials fluctuated. One more considerable detail is that at the first years of recordings first two materials were not recycled at all.
Despite the fact that plastics and aluminium cans followed a pattern with no decrease, they were first recycled in different years at different rates. Starting from 1986 aluminium cans were recycled at about 4%, for plastic waste materials the first year they were recycled was 1990 at around 2%. While aluminium waste products recycle rate rised agressively ending up at 45% in 2010, plastics remained under 10% over the period, climbing at negligible rate and reaching only 9% in 2010.
As for other two materials the percentages were larger and the patterns they followed were completely different. In 1982 the rate paper materials and glass containers recycled was 65% and 50% respectively. In the following years glass containers experienced a rapid fall, decreasing to 40% in 1990. Paper and cardboard products increased by 5% in 1986, but then decreased to 66%. After 1990 there was no decline for glass containers, their rate gradually rised and stoped at 60%, but for paper waste materials there was a rapid jump to 80% in 1994 after which there was no change at rate and by the end of the period it was 70%.
