3 1. Waste management in Germany Responsibilities i for disposal according to Closed Cycle Management Act Waste from households: Local authorities (public sector) Waste from industry, trade, mining and demolition and construction: In competition (private sector) BUT: Local authorities are not responsible for disposal of packaging g from households (Private sector / dual system) Hamburg: Stadtreinigung Hamburg 3

4 1. Stadtreinigung Hamburg (SRH) Household waste management in Hamburg Area Hamburg: 755 km² Inhabitants: 1,8 Mio. Households: SRH: public company by legal basis since 1994; responsible for waste collection and treatment from private households Owned by Free and Hanseatic City of Hamburg (FHH) Financed by fees Waste management for around 1.2 Mio. tons/a (household waste, waste from industry and trade, waste from other municipalities) 4

5 1. Stadtreinigung Hamburg (SRH) Facts and figures of SRH Duties according to SRH-law are carried out with around 2,500 employees and 700 vehicles Public duties Commercial activities Others Disposal (collection, transport, treatment) of household waste Disposal (collection, transport, treatment) of household waste Appropriate to object of company SRH e.g.: Cleaning service of streets and pavements Winter service Cleaning service of streets (events) Winter service In competition with private companies Plants for energy production (solar, wind, landfill gas) Marketing of paper 5

6 1. Stadtreinigung Hamburg (SRH) Household waste management in Hamburg Kerbside collection of household h waste in four bins Residual Paper waste 472,000 t (262 kg/inh.) 59,000 t (33 kg/inh.) Packaging Biowaste 4,000 t (kitchen and (SRH-amount only; In total: 32,000 t) garden waste) 54,000 t (2 kg/inh.) (30 kg/inh.) In addition 6 17,500 t bulky waste collection on demand

7 1. Stadtreinigung Hamburg (SRH) Household waste management in Hamburg Bi Bring system 13 waste receipt stations ~103,000 t in 2012 on receipt stations accepted Paper, bulky waste, green waste, e-scrap, hazardous waste etc. Bi Bring system Depot containers for paper 22,000 t in 2012 collected (SRH is not responsible for glass collection in depot containers) Kerbside and bulky waste collection: 605,000 t 7

8 2. Climate/resource protection at SRH Wet fermentation plant (SRH 47,5%) Capacity: 20,000 t/a Dry fermentation and composting plant Capacity: 70,000 t/a Rugenberger Damm incineration plant (Vattenfall, SRH, EWE) Capacity: t/a Contract until 2019 Stapelfeld incineration plant (E.ON) Capacity: t/a Contract until 2016 Stellingen SRH-owned incineration plant Capacity: 180,000 t/a Hamburg Borsigstraße incineration plant (Vattenfall, E.ON) Capacity: t/a Contract until 2014 Incineration plant for hazardous waste Capacity for incineration > 1 Mio. t/a Capacity for biowaste treatment ~ 70,000 t/a + 20,000 t/a 8

9 2. Climate/resource protection at SRH SRH: On the way of climate and resource protection X New law With focus on climate and resource protection Extension of energy and resource management, vehicles, electric mobility, renewable energy sources (wind, solar, photovoltaics, landfill gas), extension of separate collection since January 2011 (Hamburger Recycling-Offensive) 9

10 2. Climate/resource protection at SRH Recycling-Offensive i of SRH: To increase separate collected waste fractions! (amount of waste; changes 2011 to 2012) Residual waste -25,000 t (-5%) Paper +300 t (+0.3%) Packaging +1,800 t (+79%) (SRH-amount only; In total: +2,300 t) Biowaste +10,500 t (+25%) Green waste +3,300 t (+20%) 10

11 3. Dry fermentation plant In 2009 SRH decided d to improve biowaste treatment due to e.g. cost reduction, climate and resource protection (biogas, soil conditioner), disposal safety Construction of dry fermentation plant as upstream facility to composting plant: Biowaste double strategy 1. Biogas production by fermentation 2. Compost production by composting of digestate from fermentation 11

12 3. Dry fermentation plant Capacity t/a ( t biowaste; t green waste) Materials disturbing the process t/a (metals, plastics) Compost t/a Green waste / wood for small t/a woodchips heating plant Performance: 850 kw Initial operation of dry fermenation plant in December

15 5. Biomethankonzept Erzeugun ng Fossiles Erdgas Elektrolyse l von Wasserstoff aus Überschussstrom Vergasung und Biogas aus Biogas aus Biogas Methanisierung Organikabfällen Industriereststoffen aus Algen von Holzabfällen Biogas aus landwirtschaftlichen Reststoffen Verteilung ng + Speicherun Deutschland Länge ca km Speicherkapazität ca. 20 % des Jahresverbrauches Wärme Strom Transport Nu utzung Brennwerttechnik Dezentrale KWK Gaswärmepumpe Blockheizkraftwerk GuD-Kraftwerk Landtransport (CNG-Fahrzeuge) Lufttransport (Gas-to-Liquids (GtL))

16 5. Biomethankonzept Systemaspekte Vorteile als Brennstoff Biomethan kann zur Erfüllung der Klimagasreduktionsziele beitragen insb. im Transportsektor, wo die verfügbaren Optionen begrenzt sind. Biomethan als "grüner" und umweltfreundlicher Energieträger kann zum Umweltschutz vor Ort beitragen. Biomethan als heimischer Energieträger kann zur regionalen Wertschöpfung beitragen. Biomethanbereitstellung in unabhängig von politischen Krisen (Versorgungssicherheit) Systemtechnische Vorteile Unerschlossene Biomethan-Potenziale sind noch vorhanden Zur Biomethanerzeugung g können unterschiedliche biogene Stoffströme und insbesondere Rest- und Abfallstoffe dezentral genutzt werden. Biomethan kann mit der vorhandenen Erdgas-Infrastruktur transportiert, verteilt und gespeichert werden Biomethan kann mit hoher Umwandlungseffizienz im Wärme-, Strom- und Transportmarkt eingesetzt werden 16

17 5. Biomethankonzept Marktreife von Systemkomponenten t Stand der Technik Biogaserzeugung aus organischen Abfällen sowie industriellen und landwirtschaftlichen Rückständen und Nebenprodukten Aufbereitung und Einspeisung von Biogas ins Erdgasnetz (z.b. Bützberg) Biomassevergasung von Holz zur Kraft-Wärme-Kopplung (z.b. Güssing/AT, Ulm/DE) Transport, Verteilung und Speicherung im Erdgasnetz (Deutschland: Länge ca km, Speicherkapazität ca. 20 % des Jahresverbrauches) Umwandlung von Methan in flüssige Kraftstoffe (Gas-to-Liquids) (Shell Pearl GtL, Quatar) Demonstrationsmaßstab Biomassevergasung und Methanisierung (Güssing/AT) Elektrolyse von Wasserstoff zur Speicherung von Überschussstrom (Falkenhagen/DE) 17

18 6. Future prospects Guarantee of long-term safe and secure disposal of municipal solid waste and stable fees Intensifying of separate collection, climate and resource protection, energy production Increase of reuse and recycling rate Improvement of labour efficiency Improvement of cleanliness in Hamburg Intensifying of innovative waste collection systems (e.g. subsurface containers) Strengthening of citizen value 18
