The pie charts below give information about the composition of household rubbish in the United States in two different years.

The pie charts show the composition, in different categories, of domestic

waste

in the United States in 1990 and 2007.

Overall

, paper and organic

waste

were the main types of household litter in 1990. After 17 years, organic

waste

alone made up almost half the refuse of houses in the US. Taking a closer look at the charts, in 1990 more than one-third (35%) of domestic

waste

was paper.

This

percentage significantly dropped to only 16% in 2007.

Also

, other types of

waste

products,

such

as glassware, metals, and textiles, showed slight declines over

this

span of 3%, 2%, and 1% to be 5%, 3% and 3% respectively.

On the other hand

, organic refuse was the second-highest

waste

category at 29% in 1990. After 17 years

this

number jumped to 42% of total rubbish, thereby being the primary

waste

product.

Similarly

, the proportion of wood rubbish increased, though slightly, to 8%,

while

plastic

waste

remained stable at 6% in both years. In 1990, 7% of domestic refuse was attributed to the dust/ cinders category, which disappeared in 2007 to be replaced by miscellaneous rubbish, which accounted for 17% of household refuse.
