Historic developments of Dutch household food waste

The latest figures on the quantities of Dutch household food waste are available for the years 2010 and 2013 \cite{van_westerhoven_bepaling_2013}.
They show that between 2010 and 2013 household food waste quantities did not change significantly.
The uncertainty margins are larger than the measured differences.
In 2010, 37 kilograms of avoidable (edible) food products were found in the residual and organic waste stream.
The unavoidable (inedible) fraction amounted to 29 kilograms.
Taking together avoidable food waste from the residual and organic stream with alternative routes (e.g. toilette, kitchen sink), the total number of avoidable food waste was 48 kilograms.
In 2013, avoidable food waste found in the organic and residual stream was 35 kilograms.
The unavoidable fraction amounted to 30 kilograms.
Taking together the avoidable waste with the alternative routes, total avoidable food waste amounted to 47 kilograms.
Thus, avoidable food waste found in the residual and organic stream reduced by 5.41% in 2013 compared to 2010; the unavoidable fraction increased by 3.45%; the total amount of avoidable food waste decreased by 2.08%.
