Part 1 Sweden Avfall Sverige – The Swedish Association of Waste Management
Sweden • 9,5 million inhabitants • 450 000 km2
Avfall Sverige • The Swedish Association of Waste Management • 400 members, primarilywithin the public sector, butalso private enterprises -service providers for the Swedish citizens • Networking, training and lobbying • National memberof Cewep, ECN, ISWA and Municipal Waste Europe
Part 2 Waste – a Resource The Development Responsibilities Operations
Waste - a resource • 2012: • 14,7 TWh districtenergy -> 20 % of the total districtenergyin Sweden - the heatingneedof 900 000 homes • 1,7 TWh electricity – the needof 250 000 homes • 2012: • 353 GWh vehicle-fuelproduced from foodwastereplacedabout 30 millions liters of petrol. • 725 000 tonnesbiofertilizerproducedreplacingindustrialfertilizer
Important steps of development • Late 1800:Cholera-epidemic - start of municipal waste management • 1950’s: • Districtheating systems developed • 1970’s and 80’s:Oil crises - waste is beingused for districtheating

Clear national targets and long-term regulations and economicalsteering instruments Household waste to landfill per year (tonnes) 50 % Landfill tax introduced Ban on landfillof combustiblewaste Producers’ responsibility introduced Ban on landfillof organicwaste Municipal waste planning compulsory National target on foodwaste recycling
National target on foodwaste recycling Old national goal: • By 2010 at least 35% of food waste from households, large-scale kitchens, stores and restaurants is recycled through biological treatment We reached approx. 25 % - with no legal requirements! New national goal: • By 2018 at least 50 % of food waste from households, large-scale kitchens, stores and restaurants is separated and treated biologically so that nutrients are utilized, and by at least 40 % being treated to recover energy.
Clear division ofroles and responsibilities Producers: • Collection and treatmentofwastewithin the ProducersResponsibility • Municipalities: • Collection and treatmentof municipal waste • Companies/Industries: • Handling ofowngeneratedwaste • Citizens/households: • Separation and leave/transport wasteat indicatedcollectionpoints
Benifits with public waste management responsibility • Front runner position todevelop • Competence • World classinfrastructure • Environmental and social benefits • Ensures long term and holisticworkaccording to the wastehierarchy
Plans, regulators, permissions and supervision National level • Parliament • National environmentaltargets • The Swedish Environmental Protection Agency • National waste plan • Producesnational legislation and guidelines • National environmental courts (5 plus onesuperior): • Gives permissions to largertreatment plants Regional level(21 counties) • County Administrative Board - government authority: • Regional environmentaltargets • Permissions and control for mosttreatmentplants • Supervision of the regional treatmentcapacity Municipal level(290 municipalities) • Municipal authorithies: • Localenvironmentaltargets • Localwaste plans and regulations • Permissions and control of smallertreatmentplants
Organisation and operation Municipalitiesdeal with theirresponsibility in different waysand design theirownwaste management organisation Organisation: • About 50 % municipal companies Collection: • 73 % outsourcing (mainlyto private companies) Treatment: • About 65% outsourcing (mainlyto municipal companies)
Owner-shipofwasteincinerators • Municipally owned plant • Co-owned regional waste company (2 out of 32) • Full-owned energy company • Full-owned multi-utility company • Privatly owned plant (4,5 out of 32)
Clear division ofroles and responsibilities Implementation and operation Responsibility • Private and public wastemanagement sector • Knowledge- and Equipment supply • Treatment- and Collection services Producers • Municipalities Companies/Industries Citizens/households
Co-operation Co-operation – the solution to an increasingly complex waste management Thru • Common municipal waste company (20 regional companies in Sweden) • Common municipal waste association (8 associations in Sweden with totally 28 municipalities) • Common board (4 common boards in Sweden with totally 9 municipalities) • Common procurement on specific issues matters
Part 3 OverviewModel Infrastructure Collection Recovery and Recycling
Public awarness - a successfactor Keymessages and tools for motivation and tofacilitatecollaboration: • Communication • Developmentofselfinstructive systems • Feed back of the results and that ”whatIdo matters” • Emphasize on the wasteholdersresponsibility and participation
Waste prevention • Long tradition of reusethroughflea markets, second hand, collection at recycling parks, etc • Depositfee system for bevarage containers/bottles • Foodwaste, textiles, electronical and demolitionwaste in focus – goalsproposed • Largestchallenge: decouplingbetweengeneratedwaste and economicgrowth
Infrastructure Collection ofwaste from householdsbased on source separation • Curbsidecollection • 5 800 unmanned recycling drop-off stations • 630 manneddrop-off recycling centers Treatmentand recycling ofwastebased on the charcterof the waste • 60 organicwastefacilities • 34 waste to energy plants • 78 landfills
Collection Collection ofwaste from householdsbased on source separation • Curbsidecollection for combustible and foodwaste (and sometimespackaging and paper) • 5 800 unmanned recycling drop-off stations for for packaging and paper • 630 manneddrop-off recycling centers for bulky, electronical and hazardouswaste • Various solutions for hazardouswastecollection
Innovation and trends in collection • Multi compartmentcollection vessels • Opticalsorting • Vehicles on biogas • Automated vacuum systems • Underground containers
Sortingequipment for foodwaste • Three groupsofwaste bags used: • Paper bags • Plastic bags • Bioplastic bags • The choice of bag depends on the pre-treatmentmethod
Infrastructure Treatment and recycling ofwastebased on the characterof the waste • 60 organicwastefacilities • 34 waste to energy plants • 78 landfills

Generation ofdistrictheating and electricity • Covers around 20 % of the total districtheating in Sweden, equals the needs of 900 000 homes • Produceselectricitycorresponding to the needs of 250 000 homes • Advanced and secureflue gas treatment • Most of the rest-productscan be recycled Total energyproduction 2012: Districtheating: 13 TWh Electricity: 1,7 TWh (includingindustralwaste)
