20 The largest waste treatment centre in the Nordic countries Field for topsoil Field for untreated wood Post-ripening field Field for green waste 20 Ämmässuo eco-industrial centre 1. Office buildings 2. Ämmässuo Sortti Station 3. Scale station 4. Composting facility 5. Old composting facility 6. Biowasher 7. PIMA hall 8. PIMA field 9. Water station 10. Gas power plant 11. Sedimentation basin for aggregate-containing sludge material 12. Baling field 13. Landfill 14. Reception field 15. Ash compartment 16. Old landfill 17. Slag field 18. Sorting station 19. Biogas facility 20. Biogas power plant

21 Reception of waste In 2017, ca tonnes of waste was received at the Waste Treatment Centre Sortti Station, operating within the Waste Treatment Centre, receives small loads of waste as well

22 Waste treatment Ämmässuo Eco-industrial center

23 From landfilling to waste treatment Mechanical seperation and treatment of reusable waste fractions - Sorting hall received and treated tn of waste tn waste from sorting stations in 2017 Mineral waste is used in landfill structures and infrastructure building at the eco-industrial center - Received total tn of mineral waste in 2017 During Vantaa Energys maintenance brake municipal mixed waste is received and bailed - In 2017 close to tn of mixed waste was received for bailing and intermediate storage In addition intermediate storage of seperately collected waste fractions

24 Treatment of biowaste and garden waste Ämmässuo Waste Treatment Centre

25 Collection and treatment of biowaste Collection began in the Helsinki Metropolitan Area in 1993 Composting in open-air stacks First tunnel composting facility in 1998 Second tunnel composting facility in December 2006 Biogas facility in 2015 The annual capacity is tonnes of biowaste and wastewater sludge, which results in cbm of ripe compost Biogas CHP in 2016

26 Collection and treatment of biowaste Stabilising medium

27 Operating principle of a dry digestion facility Fine-grained biowaste Biogas Vacuum output system Feed screw M i x e r s Digestate

28 Use of biogas The biogas facility produces renewable electricity and heat from gas Use of compost mass and quality control Quality control according to the Fertilisers Regulation (ca. 40 parameters) Compost is sold to the topsoil production

29 Treatment of fly ash, bottom ash and boiler slag from the waste-toenergy plant Ämmässuo Waste Treatment Centre

30 Stabilisation and final disposal of fly ash and boiler ash Ca t/a is received Due to its high chloride content, this is hazardous waste Stabilised with cement, finest-grained mineral material of slag, and water. This prevents the dissolution of detrimental substances. Final disposal at the landfill for hazardous waste

31 Treatment of boiler slag Ca t/a is received Magnetic and non-magnetic metals are separated in the treatment and put to recycling The remaining mineral material, screened by its grain size into separate fractions, can replace virgin mineral materials

32 Treatment of contaminated soil extracts Ämmässuo Waste Treatment Centre

33 Utilisation of contaminated soil extracts as such Principal contaminants: organic compounds Treatment methods: pore gas treatment and/or composting Heated treatment hall for contaminated soil extracts (PIMA hall) enables all-year-round degradation of harmful substances Apart from the PIMA hall, there is a VOC hall for treating soil extracts contaminated through volatile compounds Utilised in landfill structures and in landfill landscaping Soil extracts contaminated by heavy metals can also be utilised at the HSY landfill

34 Landfilling Ämmässuo Eco-industrial center

35 Landfill treatment and final disposal Old landfill, 53 ha In use between Over 11 million tons of waste is final-disposed there Height of the waste fill is over 40 m Landfill, 55 ha Introduced in 2007 The first 12.4 hectares are now in use Municipal solid waste unsuitable for reclamation, construction waste, rejects and soil extracts are finaldisposed here Final disposal of domestic waste was discontinued in 2016

36 After-care of the landfill According to the law, a time period of at least 30 years must be reserved for the after-care Due to the extensive size of Ämmässuo, the need for after-care will last, in practice, for several decades longer The after-care includes Monitoring of leachate collection and sewer system and prospective maintenance of leachate recycling for maintaining gas formation Monitoring of the gas collection system as a whole and pipe by pipe; monitoring of the amount and methane-concentration of collected gas Monitoring of the surface insulation structures and begin prepared for remodelling and repairing them along with the indentations Environment monitoring

37 landfill gas Ämmässuo Waste Treatment Centre

38 Utilisation of gas Formerly used as district heat at Fortum s Kivenlahti heating plant with a utilisation rate of 50 60% From 2010 onwards, as electric and heat energy in the gas power plant with a utilisation rate of ca. 90% (2017: 87%) Improves as a CO 2 neutral fuel (LFG) significantly the utilisation of landfill and replaces fossil fuels in energy production of the Helsinki Metropolitan Area The reduction of carbon dioxide emissions is conditional upon the type of the replaceable production form

39 Gas power plant Based on the gas-engine technique, strict conditions set for the environmental permit Production of additional electricity from the waste heat of electricity production (ORC) Total investments with the management agreement ca. 15 million euros (investment support, granted by the Ministry of Employment and the Economy, is 22% of the total investments) The project has won several prizes Climate Action of the Year 2010 Energy Globe Award 2012

40 Milj. Nm 3 (CH 4 50 %) The amount of landfill gas generated and utilised in Vuosi Collected gas amount Utilised gas amount

41 MWh Ämmässuo produces more energy than uses it Produced Bought Sold Own consumption

42 Water management Ämmässuo Waste Treatment Centre

43 Water management Landfill water: Leachate Process water from composting Sanitary water Water from waste treatment and storing areas Clean surface water: Irrigation, washing, dust suppression, fire extinguishing Led to open trenches Online monitoring Field measurements

44 Water station Different wastewater sections are directed in their own pipelines to the water station Centralised monitoring of water quality and amount Possibility to recycle leachate to the old landfill Directing wastewater to the Suomenoja wastewater treatment plant for treatment Ca m 3 wastewater in % of the entire nitrogen load of the Suomenoja wastewater treatment plant, 1% of the water amount

45 Water management is part of landfill aftercare

46 Environmental monitoring Ämmässuo eco-industrial center

47 Air quality and measurement Continuous measurement of PM 2,5, PM 10 and reduced sulphurs Odor complaints Methane leakage detection at landfills Emission measurements

48 Ämmässuo and Kulmakorpi water quality monitoring program I collaboration with other companies working at the site HSY incharge of managing the program 75 measurement points Surface and groundwaters Nearby lakes Wastewaters and wells Water sampling and analyzing 4-6 times a year

49 Other environmental monitoring Trash Visual inspection Cleaning and collection Noise measurements 3-4 x year 3 measuring points Pests Pest controll 2 x month Hygiene monitoring 1 x year
