Take Lille, for example

  1. 1. WATER INNOVATION: BRIDGING GAPS, CREATING OPPORTUNITIES 27 AND 28 SEPTEMBER 2017 ALFÂNDEGA PORTO CONGRESS CENTRE THE GOOD OLD SEWAGE WORKS IS NOW YOUR COMMUNITY RESOURCE FACTORY TAKE LILLE, FOR EXAMPLE ERIC NESME VEOLIA
  2. 2. Paradigm Shift: WWTP Sludge from a Waste to a Resource The good old sewage works is now your community resource factory
  3. 3. 3Porto Water Innovation week Circular Economy  New (r)evolution for water and wastewater management A paradigm shift for WWTP sludge Wastewater sludge is not anymore a WASTE BUT A RESOURCE Adapted from Water Environment Federation Low carbon economy Digital economy
  4. 4. WWTP sludge challenges and opportunities 4 Sludge Treatment Design & Build, Operation, Merchant plant, … Periodic services Porto Water Innovation week Sludge equipment is about 45% of the global wastewater equipment ≈ 280 M ton of sludge produced in Portugal Sludge Disposal Management Turning Waste into Resources
  5. 5. 5Porto Water Innovation week Sludge management is local and specific  Some market drivers to chose the best solution for sludge management MARKET INCENTIVEREGULATION Composting Land spreading Landfill Attractive market price for: - Energy (Electrical and biogas feed-in tariffs) - Phosphorus - Nitrogen - Need for soil amendment ENVIRONMENTAL & SOCIAL INTEGRATION
  6. 6. 1 - Technologies adapted to local objectives France, Marquette-lez-Lille WWTP 6Porto Water Innovation week Key figures: 620,000 p.e. capacity 4.8GWh produced each year by treating sludge Volume of sludge reduced through: Digestion EXELYS® Thermal Hydrolysis BIOCO® Drying Process Water reuse on site: Compact Nanofiltration unit  Sludge volume reduction  Energy recovery  30% more biogas produced thanks to EXELYS® process
  7. 7. 2 – Combination of WWTP sludge and organic waste Denmark, Billund BioRefinery 7Porto Water Innovation week  Biogas from WWTP sludge and biowaste to supply heat and electricity Key figures : Wastewater: 70,000 p.e. Organic waste: 4,200 tons Energy production: 12 GWh per year Biofertilizer production Technologies: EXELYS® Thermal Hydrolysis Hydrotech® Discfilter An example of the circular economy: Wastewater Plant of the Future
  8. 8. 8Porto Water Innovation week 3 – Produce biogas with injection into the grid France, Cagnes-sur-Mer WWTP  Biogas production optimized  Drastic energy consumption reduction  > energy produced than consumed A POSITIVE ENERGY BALANCE Electricity consumption = 8,7 GWh/year Bio-methane production = 10,5 GWh/year Electrical energy consumption Bio-methane production
  9. 9. 9Porto Water Innovation week 4 – Innovation in the business model France, Artois Méthanisation  25,000 t of waste treated per year  Organic waste double recovery: agronomic and energetic Key figures : Electricity production: eq. of 2,700 households 2,000 tons of CO2 avoided Waste treated: Agriculture waste Wastewater biological sludge Local authorities waste Other organic waste An example of the circular economy: a facility designed, built and owned by Veolia
  10. 10. 10Porto Water Innovation week 5 - Environmental integration and energy recovery Hong-Kong, T-Park sludge incineration  Largest sludge treatment plant in the world  Ensure the energy recovery of sewage sludge from a 7,2 millions inhabitants area Key figures : Sludge coming from 11 WWTP Capacity: up to 2,000 tons in year 2030 Integration in the social life Heat recovery and power generation system Water autonomy & zero-wastewater discharge
  11. 11. 11Porto Water Innovation week Conclusion - Sludge from a Waste to a Resource  Turning sludge from a waste to a resource is a technological challenge  It needs to optimize the overall economical equation (Capex + Opex)  A comprehensive understanding of the overall sludge management and financial data is essential To keep in mind: WWTP sludge valorization is one lever only to value waste in a territory (biowaste, …)
