  1. l’Eau, votre service public l’Eau, votre service public Thematic session - Towards a sustainable approach to sludge management: legal frameworks and technological solutions SDEA’s approach Edinburgh, 27/06/2019

  2. Territoire Est Mosellan - Sarre SDEA – managing water in eastern France Territoire Nord SDEA unites 668 municipalities and 1 020 000 inhabitants : Territoire Ouest 2 Territoire Centre Nord Siège du SDEA - EMS • 7 agencies • 11 000 kmlgrid, 2000 plants / structures • 615 agents • Total Budget : 200 M € • (WW : 121 M€) Territoire Centre Sud 634 Municipalities 395 Municipalities 514 Municipalities Territoire Alsace Centrale Drinking Water Wastewater River&Basin Management 2

  3. SDEA and wastewater management • 7023 kmlwastewater pipe grid / 90% unitary • 109 wastewatertreatment plants • Total capacity 895 500 PE • Biologicaltreatment : 100% • ActivatedsludgeWWTPs : > 98% capacity • Averagecapacity 8400 PE (50-102000) Sludge production : 13500 dry tons/year Disposal : agricultural valorization : 100% (100% norm / agricultural disposal compliance) Composting 40% / Spreading 60% Drying : solar, centrifugation, press + combinations 1 active methanization plant + 1 project

  4. France : a disposal based on agriculture, but…

  5. Threats on sludge disposal EU legislation : mandatorysorting of waste Sludgeisconsidered as waste • French ministriesinterpretation : no mixing of sortedwaste • Forbids compost (out of exemptions) and comethanizationwithotherwaste (industrial fat waste, green waste…) Other long-termthreats for agricultural disposal : badreputation (sludge = micropollution), wastewater money ≠ taxpayer money Agriculture - environmentperceived opposition Examples of nearby countries (Switzerland…)

  6. Short/Long term Sludge disposal policy French level / Ministries of agriculture and environment– circulareconomylaw (currently in discussion) : Action with FNCCR to legalize/defendlawfulness of comethanization of biological or green waste + compostingwithgreen/biological waste Methanization plants on WWTP Comethanizationwithlow-impact crops (sylphium, clover, raygrass, non-ediblepeas, …) positive effect on local aquifer Residuedisposal? Mass methanization of sludge(common plants by area) as sludgemixingwillbepermitted /!\ transport = CO2 emissions + costs

  7. Thankyou for your time ;)
