  1. REnescience at Amagerforbrænding 2012 By Project Manager Frank Hansen

  2. Agenda Brief introduction to Amagerforbrænding REnecience at Amagerforbrænding Site visit REnescience

  3. The owners of Amagerforbrænding Amagerforbrænding is owned by the municipalities of Dragør, Frederiksberg, Hvidovre, Copenhagen, and Tårnby - 730.000 inhabitants - 46.000 companies and institutions

  4. Business activities Landfill Recycling Waste to Energy plant Co-ownedwithVestforbrænding 9 recycling stations Production of heat and electricity 405.000 tons in 2010 - District heating since 1970 - Electricity since 1991 - Heat supply for 80.000 households - Power supply for 50.000 households 78.000 tons in 2009 Environmentally safe landfill 110.000 tons in 2010 - 73 % is recycled - 24 % is incinerated - 3 % is deposited

  5. Amager Bakke • State-of-the-art environmental performance • Modern and flexible design • Urban integration • Flagship Waste to Energy

  6. REnescience –wasterefinaryRenewables, Science and Renaissance of the energy system The objective of the REnescience project is upgrading of household waste for optimal use of the energy content and of the basic elements –with least environmental impact. Sponsored by

  7. Project goal • Householdwaste REnescience is wasterefining The goal is to develop a continuousprocessthataddsvalue to the wastethrough: • Liquefication of the bio-degradablefraction for optimal separation and utilisation • Recycling of metals,glass and plastic • Energy recovery of burnablefraction

  8. Method for waste treatment of the future

  9. Gain for society • Highenergyutilisation • Possibility for storing the liquid fraction and use as needed - in term of time and location • Production of a wide range of energyproducts i.e. biogas, bioethanol • Biogas can be used for • heat and power production • feeding to the natural gas net work • Transport • Power production in existingplants–replacingcoal/oil • Saving ressources • Metal, plastic and glassarerecycled and not lost • Soilimprovement (nutrientsareretained is residual from biogas production)

  10. REnescience-refining of waste Separation Separation Solid fuel Metal Glass Plastic Textiles, wood, plastic Recycling Liquefication Separation Enzymes Solid fraction Enzyme treatment 30-60 °C Heat treatment 100 °C Householdwaste Liquidfaction Heat Water Energy containing slurry

  11. REnescience – Technology spin-off Let’sseehowthisworks out 2005

  12. Initial tests – batch reactor Solid fraction with metal and plastics. 2006 50 kg batch processing with enzymes Liquid bioslurresuitable for biogas production

  13. End products – afterenzymetreatment Solid fractionconsisting of plastics and metals Bio slurry

  14. REnescience – pilot plant A pilot plant for treatment of 800 kg of waste per hour has beendeveloped and build. Operation commenced in december 2009. The plant is located at Amagerforbrænding. The enzymereactor is 16 m long and has a diameter of 2,5 m 2009 In the heat reactor the waste is prepared for the enzymetreaement Vibration sieve for separation of the liquid and the solid fraction

  15. REnescience – EUDP funded research project Elements of currentinvestigations: Washing and drying of solid fraction Optimisingautamaticcontrols Long term operation of pilot plant (7.000 timer) Reduction of enzymeconsumption Odourreduction Recycling of solid fraction Biogas production Design og feasibility studie of 10t/time plant LCA Life Cycle Analysis 2009

  16. REnescience – EUDP funded Research project • Preliminary results: • Biogas production: high biogas yields from bioslurry. Problematiccontents of phatalater. Low concentration of heavy metals • Enzymeprocessworkswell with ”un-sorted” municipal solid waste. • Recycling of plastics not solved as yet. Difficult to seperate from rest of solid fraction. • LCA: comparable with bestpractisewithinwasteincineration. • Odour problems needs to besolved. • Glass cannotberecovered. • Business case ?? 2009

  17. REnescience – EUDP funded research project Preliminary design of 10 t/h demonstration plant: 2009

  18. REnescience - Overall Time frame Renescience pilot project Start 2007, end 2011 Capacitet: 0,8 ton/h Project duration 4 år EUDP project study Start Q3,2010, end Q3, 2012 Duration 2 year Focus: full scale establishment 2017 2009 2008 2020 2019 2021 2010 2018 2014 2012 2016 2011 2007 2013 2015 Design & Construction of full scale demonstration plant for commercial operation.
