Petersen (2001) and Petersen & Hansen (2003) provides 1997-2001 activity
data for the composting of garden and park waste (GPW). Activity data for
GPW for the years 1985-1996 and 2002-2010 are estimated from the surrogate
data gathered from the waste statistic reports, Affaldsstatistik 2007 & 2008
(and earlier years).
The waste statistics provides the development in composting and wood
chipping of GPW for 1995-2009, and by looking at the trend of this development
the remaining years 1985-1994 and 2010 are estimated. This data series
is used.

The last waste category involved in composting is home composting of garden
waste and vegetable waste. The activity data for this category is known
from Petersen & Kielland (2003) to be 21.4 Gg in 2001. It is assumed that the
following estimates made by Petersen & Kielland (2003) are valid for all
years 1985-2010.
• 28 % of all residential buildings with private gardens (including weekend
cabins) are actively contributing to home composting.
• 14 % of all multi-dwelling houses are actively contributing to home composting.
• 50 kg waste per year will in average be composted at every contributing
residential building.
• 10 kg waste per year will in average be composted at every contributing
multi-dwelling house.
The total number of occupied residential buildings, weekend cabins and
multi-dwelling houses are found at the Statistics Denmark website. The calculated
activity data for home composting of garden and vegetable waste
are shown in Table 7.11 and Annex 2D Table 2D-5.
