“According to the ‘European Dioxin Emission Inventory,Stage II’ (Landesumweltamt Nordrhein-Westfalen, December 2000), funded by the Commission,incinerationof municipal solid wastes has experienced arapid decreaseof dioxin and furan emissions to air during the last decadedue to efficient abatement measures : dioxin emission levels in 2000 have decreased by 58 % compared to the levels in 1995 and they foresee a decrease of 81% comparing the levels of 1995 to 2005”Mrs. Wallström 500g/an 300g/an 200 160 5 g/an 1998 1999 1997 2006 2000 Dioxins : rapid decrease, efficient abatement France FEAD seminar inEcotech 2003, Amsterdam , 14 May 2003 : ENERGY-FROM-WASTE, A Secure and Sustainable Energy Source
Main concern : Uncontrolled burning “For the industrial sources a considerable emission reduction has been achieved (based on current trends and activities it is foreseen that thetarget set in the 5th Environment Action Programme of a 90% reduction will be nearly realised in 2005 compared to the levels in 1985). But, for the non-industrial sources (domestic solid fuel burning, domestic waste burning, fires, etc.) the rate of emission reduction is much lower. The relation between industrial and non-industrial sources is shifting towards growing importance of non-industrial sources” Mrs. Wallström on behalf of the Commission FEAD seminar inEcotech 2003, Amsterdam , 14 May 2003 : ENERGY-FROM-WASTE, A Secure and Sustainable Energy Source
