The line graph shows how much household waste was disposed of by three different methods in one country between 2000 and 2025, measured in millions of tonnes.

Overall, landfill went from being by far the dominant method to the least used, while both recycling and incineration grew substantially. By the end of the period, recycling and composting had become the main way of dealing with household waste.

In 2000, 22 million tonnes of waste went to landfill, compared with just 2 million tonnes that were recycled or composted and a mere 1 million tonnes that were incinerated. Over the next fifteen years, the amount sent to landfill fell continuously, while recycling rose rapidly, and the two figures converged at 11 million tonnes in 2015.

After this point, the gap widened in the opposite direction. Recycling continued to grow, albeit more slowly, reaching 13 million tonnes in 2025, whereas landfill dropped to only 4 million tonnes, less than a fifth of its 2000 level. Incineration, meanwhile, increased ninefold over the period, overtaking landfill in 2020 and standing at 9 million tonnes at the end.
