The SYSAV Case A Concept for the Reduction of Green House
The SYSAV Case A Concept for the Reduction of Green House Gases with Maximum Recovery and Minimum Landfilling Håkan Rylander, CEO South Scania Waste Company, Sweden Maximum Recycling, Minimum landfilling The Waste Problem can only be solved with an Integrated Waste Mangagement - with a Combination of Methods Driving forces Legislation – Laws, Directives etc Environmental Awareness/Environmental Engagement Education and Information The Sysav Group handled 835 000 tonnes of waste in 2008 Household waste Bulky waste Industrial waste Building and Construction waste Hospital waste Hazardous waste Electronic waste with a Combination of Methods Overall goal since 1974 Maximum recycling of material and energy, with minimum of landfilling. The Sysav Region • 4 landfills Kävlinge Burlöv • 4 transfer stations Lomma Lund Sjöbo Staffanstorp Måsalycke Tomelilla Malmö Simrishamn Svedala Skurup Vellinge Trelleborg Hedeskoga Ystad • 16 recycling centers The Eco-Cycle Model Bunkeflo Recycling Center, Malmö 1,7 million visits on Sysavs 15 recycling centers during 2008 Sysav Hazardous Waste Secure handling of hazardous waste from industries and households Building Material Recycling Shop - reuse and selling of construction and demolition material, in co-operation with Malmö Local Authority Service Administration Sydåtervinning Recycling of waste paper ÅGAB Recycling of gravel, asphalt and concrete etc. Sysav Biotec • Treatment of 25 000 ton of food waste in 2010 • Plant for the pre-treatment and the hygienisation of food waste for the production of a slurry • Fermentation of the slurry in a separate bioreactor • Upgrading of the produced biogas to a gas with fuel quality • Production of biofertilizer Composting of Green Waste Composting at four Landfill sites Compost Waste provides heat and electricity Production of • 1500 GWh of heat • 250 GWh of electricity SYSAV delivers 60 percent of the heat demand in the cities of Malmö/Burlöv 3 tonnes of waste = 1 tonne of oil Production of heat to the district heating net 550 000 tonnes equals to 60 percent of the heating demand in the cities of Malmö/Burlöv MW 700 600 500 400 300 Other production 200 100 SYSAV 41 51 61 71 81 91 10 1 11 1 12 1 13 1 14 1 15 1 16 1 17 1 18 1 19 1 20 1 21 1 22 1 23 1 24 1 25 1 26 1 27 1 28 1 29 1 30 1 31 1 32 1 33 1 34 1 35 1 36 1 1 11 21 31 0 Advanced flue gas cleaning with latest technology • Electrostatic Precipitator/ESP • Wet cleaning in three scrubbers • Wet ESP • Catalyst • Water treatment plant Dioxin to air 1985 – 2007 in Sweden 14 000 000 120 12 000 000 100 10 000 000 80 8 000 000 60 6 000 000 40 4 000 000 20 2 000 000 0 0 1985 1990 1995 1999 2000 2001 2002 2003 2004 2005 2006 Energy prod. MWh Incineration, ton Dioxin (to air), g The Swedish Example The amount of incinerated waste has been more than doubled from 19852006, while the energy production has been quadrupled, and most of the emissions have decreased with 99%. Bottom ash recycling - of metals and gravels The Spillepeng Landfill – a recycling site Sorting Recycling Composting Final Landfilling Recovery of landfill gas Sysav and the climat - Scenarios GHG SYSAV Year 2010 Main scenario: Business-as-planned Alternative scenarios: 100% landfilling Electricity production at incineration only Waste treatment in the scenarios Incineration: 530 000 t Anaerobic digestion: 25 000 t Composting: 55 000 t Landfilling: 60 000 t Landfilling only Same as ”business-as-planned” ktonnes CO2-eq/year Main results – Total emissions 800 Emissions from complementary production of services 700 Direct emissions from the waste management system (Sysav) 600 500 400 300 200 100 0 Business-as-planned at Sysav 100 % landfilling Electricity production at incineration only ktonnes CO2-eq/year Main results – Total emissions 800 700 Emissions from complementary production of services Electricity production Direct emissions from the waste management system (Sysav) 600 500 Heat production 400 Heat production 300 200 100 0 Electricity production Landfilling Incineration Business-as-planned at Sysav Incineration 100 % landfilling Electricity production at incineration only Composting of Green Waste Composting at four Landfill sites Compost The Sysav Group 2008 Household waste Industrial waste (Hazardous waste Concrete, gravel, asphalt etc Recycables (paper, plastics etc) In Total Out of which landfilled Recycling of material and energy Landfilling 2007 386 200 294 100 37 600 89 815 64 868 834 983 35 069 382 300 346 700 52 000) 100 900 72 300 902 200 53 700 96 % 4% 94 % 6% Recovery versus Landfilling Sysav 2000-2005 Landfilling Recycling of materials and energy % Year Maximum recycling, Minimum Landfilling The Waste Problem is solved with an Integrated Waste Mangagement - with a Combination of Methods Thank you for your attention! www.sysav.se
