IV. Conclusions • Europe having discontinued its revision work of directive 86/278/EEC, member states (or regions) have had to develop their own strategy and statutory solutions answering to sewage sludge use requirements, as well as to outline a framework and to decide on sewage sludge treatment processes. • In order to bring support to those who opted to develop the agricultural recovery potential, the revision will have to consider, not to adopt new measures or conditions financially restrictive and technically cumbersome which should not be duly justified and to support the subsidiarity principle approach in particular to deal with some region’s industrial heritage and some soils own specificity.
