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

(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

(amount of waste; changes 2011 to 2012) Residual waste -25,000 t (-5%) Paper +300

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

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
