The bar chart compares the proportions of four types of household waste—plastic, cans, paper and glass—recycled in 1992, 1997 and 2002.

Overall, recycling rates increased for most materials over the period, with glass and paper showing the most significant growth. Plastic remained the least recycled material throughout, while glass became the most recycled by 2002.

In 1992, recycling levels were relatively low across all categories. Glass and paper were recycled at 16% and 15% respectively, while cans accounted for 18%, the highest figure that year. Plastic had the lowest rate at just 10%.

By 1997, there were noticeable improvements. Paper recycling rose sharply to 32%, becoming the leading category, followed by glass at 26%. Cans, however, declined slightly to 14%, while plastic increased modestly to 12%.

In 2002, recycling rates climbed further. Glass saw the most dramatic rise, reaching 48%, the highest overall figure. Paper also increased to 38%, while cans rebounded significantly to 24%. In contrast, plastic remained unchanged at 12%, continuing to lag behind other materials.
