Source: ISAG reports 1995, 1996 and 1997, Government's Plan of Action for waste and recycling 1993-97, Danisco, Association of Danish Recycling Industries and other large scrap dealers, reports to the Danish Environmental Protection Agency on sludge applied to farmland etc. (for 1997, figures from 1996 have been used) and incineration of sludge at waste incineration plants (for 1997, figures from 1996 have been used). Waste amounts from wastewater treatment plants include sand and screenings and are therefore slightly higher than stated in Figure 17.
