Waste problem l.jpg
Waste = problem

  • Waste = NUISANCE + resources

    • NUISANCES

      • Bulky

      • Disagreeable (visual, olfactory, …)

      • Health risks (epidemic)

      • Environmental Risk

    • Resources

      • Energy

      • Materials

  • Waste Policy : share out the money available as well as possible in order to

    • REDUCE PRODUCTION

    • MINIMISE POLLUTION potential

    • OPTIMISE RECOVERY

  • 0,1 ng/Nm3Þ « Negligible risk »

    “… providing that this legislation is enforced by Member States, a high level of protection will be ensured.”

  • 0,1 ng/Nm3 : can easily be achieved continuously in incineration plants

    “From a purely technical point of view, dioxin emissions from some processes, such as waste incineration, can be better controlled than emissions from other processes.”

    Quotations taken from the Answer given byMrs. Wallström on behalf of the Commission (12 July 2002)to a WRITTEN QUESTION (E-1585/02, 04.06.2002)to the Commission by Caroline Jackson (PPE-DE)

Dioxins rapid decrease efficient abatement l.jpg

“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

Main concern uncontrolled burning l.jpg
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

Clarify the notion of RECOVERY

  • RECOVERY Ì DISPOSAL

  • 3 levels in the EU texts

    • INTENTION to Recover (collected for sending to a sorting centre)

    • EFFECTIVE RECOVERY (OUT / IN ratio)

    • ENVIRONMENTAL RECOVERY (integrated, multiple parameters)

  • RECOVERY based on the RESULT and not on the intention

  • RECOVERY not on an ON/OFF basis, but in %age

  • RECOVERY should be judged on the whole chain and not on only one link (e.g.: sorting alone)
