It reached 2 million tonnes by the final year (2005).

Specifically, the figure for households source stood at approximately a million tonne in 1990 and dropped steadily during the period (1990; 2005). And Transport source, it started at a million tonne and showed some fluctuations throughout the period. It remained intact.
