垃圾收集趋势

The bar chart illustrates how much waste of four categories (paper, glass, tins, garden waste) was collected by a recycling centre over the period 2011 to 2015, measured in tons. Overall, paper was the most collected type of waste across the period, while all categories saw an increase in collected amounts by 2015, except for a temporary dip in garden waste in 2012. In detail, paper waste collection stood at 57 tons in 2011, before fluctuating and reaching a peak of 70 tons in 2015, making it the largest waste stream throughout the five years. Glass collection rose gradually from 48 tons in 2011 to 52 tons in 2015, becoming the second most collected waste type by the end of the period. Tins saw a steady growth, rising from 35 tons in 2011 to 39 tons in 2015, despite a slight fall to 27 tons in 2012. Garden waste was the only category that experienced an initial drop, declining to 15 tons in 2012 from 32 tons in 2011, then recovering to 35 tons in 2015, which remained the lowest among the four waste types.
