3prefaceThe Swedish Energy Agency is a governmentauthority for national energy policy issues. TheAgency’s mission is to promote the developmentof the Swedish energy system in order to makeit socially, ecologically and economically sustainable.International collaboration and disseminationof Swedish experience and environmentaltechnology are important aspects in this work.The Energy Agency’s efforts to strengtheninternational collaboration in the field ofwaste-to-energy began in 2009 when a delegationfrom Sweden visited India with thespecific interest to discuss ‘Biogas for UrbanInfrastructure’. Since then the Agency’s internationalwork in this field has intensified andtoday it reflects in several bilateral initiatives.By communicating Swedish experiencewithin the waste-to-energy sector, this bookletserves as the basis for further knowledgesharing and joint creation of sustainable wastemanagement systems. Sweden has a long historyof sustainable waste management backedby decades of gradual structural changes tostimulate the use of waste in the productionof heat, power and vehicle fuel as well as capturingthe potential in so many other residualsfrom society including waste water and surplusheat from industries.Erik BrandsmaDirector General,Swedish Energy Agency

4Main supporting partners ofthe Waste-to-Energy initiativeThe information in the booklet is a result of a combined effort between theSwedish Energy Agency and Environment and Energy clusters in Sweden as follows;SwediSh government officeSThe Government Offices form a single, integrated publicauthority comprising the Prime Minister’s Office, the GovernmentMinistries and the Office for Administrative Affairs.In collaboration with other government organisations andthe Swedish Embassies around the world, an important aimof the Government Offices is to build international relationsand increase Swedish export of environmental technology,energy efficiency and infrastructure for sustainable urbandevelopment.Sida – the SwediSh internationaldevelopment cooperation agencySida is a government organization under the Swedish ForeignMinistry. Sida administers approximately half of Sweden’sbudget for development aid. Swedish developmentaid follows three thematic priorities; democracy and humanrights, environment and climate change and gender equalityand women’s rights.ASSET, The Association of Swedish EnvironmentalTechnology Industries – a network organisation for regionaland national associations of environmental technologyindustries in Sweden.

6The systematic approachThe holistic and systematic approach to sustainableurban development is one of the keyfactors that has gained Sweden its position asa world leader in efficient use of renewable energy.Solutions are found by seeking synergiesbetween urban functions which unlock bothefficiency and ultimately profitability.Combine urban functions -and prosperThere are many ways to make urban functionsefficient. But focusing on them separately willresult in a sub-optimised system. It is the holisticapproach that is the key to lessened energydemand and reduced environmental impact.Take water – a scarcer resource than ever.Modern cleaning technology can producedrinking water from household wastewater.Along with household bio-waste, this wastewatercould serve as a resource for the productionof bio-methane and bio-fertilizer. Byaddressing these issues together it becomespossible to secure potable water, vehicle fueland sustainable farming with the same system.Another example is surplus heat fromindustries. This excess heat is often found tobe ventilated in cooling towers or in rivers orlakes. Instead, by linking the industrial systemto a city, households and other processes canhave cost efficient heating, cooling or evenpower that thereby substitutes other fossilbased sources.It’s important to recognise that a systemsapproach is not only a question of technology.Much more so, it’s a question of collaborationbetween public and private sectors and cooperationbetween different municipal departmentsenabling synergies to develop.

As shown above, solid waste andsewage water from different sources are handled in an integrated system; ultimately the residuals may be recycled, incinerated, gasified, digestedor otherwise purified for various uses. Incineration of waste provides heat and power to the end-users – both for domestic and industrialuse. Excess heat and steam from industrial processes are recovered enabling usage in other public or industrial functions. Both compressed andliquid biogas is produced from biodegradable waste and after upgrading it can be used as vehicle fuel. Through this systems approach a varietyof residuals are successfully used to replace considerable amounts of fossil fuels.In a modern, efficient and sustainable society, everything is connected.

8Waste-to-Energy definition in this booklet:Recovery of wasted energy!Inefficient use of residuals in society can be found everywhere. For example surplus steam cooled of in cooling towers, agricultural waste dumped on unusedland or municipal and industrial solid waste dumped on landfills etc. Swedish experience shows that it is often both financially and environmentally viable torecover these sources of energy. Over the past decades numerous initiatives and projects have been introduced in Sweden enabling such energy recovery.Recovery of wasted energy sources is divided into four different themes in this booklet.10 3460 84waStewater treatmentand Sludge managementExamples include systems and processes thatenable the utilization of energy in wastewaterboth in terms of thermal energy but alsoin terms of the extraction of energy from thematter content in the sewage through digestionwith bio-methane and bio-fertiliser output.municipal Solid waSte managementExamples include systems and processes thatenable the recovery of energy in solid wastethrough incineration or gasification with bothheat and power output or with the help oflandfill gas extraction techniques where the gascan be used to produce either heat and poweror alternatively bio-methane for vehicle fuel.the biogaS SyStemExamples include systems and facilities formanaging biodegradable waste with efficientproduction and innovative use of biogas.

101From<strong>WASTE</strong>WATER TREATMENT ANDSLUDGE MANAGEMENTa situation in the early 1970s, whena significant part of urban and industrialwastewater was discharged in altogetheruntreated form, today virtually all householdsin urban areas are connected tomunicipal sewage networks and roughly95% of urban wastewater undergoesboth biological and chemical treatment.This situation has been reached with thehelp of large government grants to improvewastewater treatment alongsidemajor steps taken by industry to reducetheir effluents to nature. These extensivemeasures taken during the last 40 yearshave made lakes and watercourses noticeablycleaner. Previously closed beacheshave re-opened and conditions for waterfauna have improved significantly. Majorindustrial facilities, such as mines andairports nowadays carry out their ownwastewater treatment or pre-treatment.Sludge – a reSourceDuring development of Swedish wastewatertreatment facilities, sludge was considereda resource early on. The materialcan be used either as fertilizers or for civilworks purposes and also in the productionof biogas – all of which are better thandisposal on landfill. In Sweden biogas productionis a common element in sludgemanagement, where the biogas producedcan be used as vehicle fuel or to produceheat and power. Residues from the digestionprocess can be used as fertilizer or ascovering material.induStry triggerS innovationSThe combination of an early start in theconstruction of wastewater treatmentinfrastructure and relatively strict environmentallegislation has resulted in bothpublic and private sectors gaining experiencein this sector. Furthermore, Swedishwastewater treatment technology is alsostrong in areas where Swedish industry isstrong; i.e. forestry, pulp and paper, steeland iron industry, mining, engineering andmanufacturing industry as well as in thepharmaceutical industry. Innovative technologiesand methods to optimise sludgemanagement and biogas production arecontinuously being introduced by Swedishcompanies.BENEFICIARIES:ManufacturingindustrySEPARATIONATIONATSOURCERECYCL<strong>IN</strong>GRecyclablesRawConstructionmaterialmaterialBuildingsectorReuseProducedbiofuelOtherfuelsWastebasedfuelConsumersectorFlue gasSurpluscondensatio<strong>ENERGY</strong>RECOVERYIndustrySurplusIndustrialsector<strong>WASTE</strong> FROM:• Households• Industry• Agriculture• Forestry• Waste WaterTreatment PlantsMIXED <strong>WASTE</strong>PresortingCombined Heat andPower PlantSteamindustrial useSOLID <strong>WASTE</strong>IncinerationSEWAGE TREATMENTSEPARATION AT SOURCEResidual wasteLandfill biocellsDistrictElectricityheatingor coolingPublicsectorLandfill gasDegradableorganic wasteBiofertilizerAgriculturalsectorBiogasproductionthroughdigestionSludgeSoil conditionerDIGESTABLE<strong>WASTE</strong>IndustrialsectorPublicsectorPurificationand Upgradingof the biogasTransportationsectorthe dotted line provideS an indicationof proceSSeS covered by thiS theme.See alSo main illuStration in page 7.

The bulk of it is compostedand used as topsoil. Some is stored for sixmonths to allow harmful bacteria to die out andthen used as fertilizer on farmland.from Sludge to biogaSAnaerobic digestion of sewage sludge createsbiogas, which is an excellent energy source. TheRya WWTP produces over 60 GWh of biogas peryear and receives fats and organic waste fromrestaurants, schools and food producers acrossthe region to boost biogas production. GryaabAB sells the raw biogas to the power company,Göteborg Energi AB where it is upgraded andthen sold to Fordonsgas Sverige AB who in turnsells it to consumers as a vehicle fuel.heat from waStewaterBefore being discharged into the Göta river,some of the treated effluent from the plant ispumped to the nearby Göteborg Energi AB heatpump plant where heat exchangers extract heatfrom the wastewater and transfer it to the districtheating system. This, otherwise wasted energy,accounts for about 7% of Gothenburg’sdistrict heating.

342Sweden’sMUNICIpAL SOLID <strong>WASTE</strong> MANAGEMENTfirst priority in its waste managementstrategy is to prevent wastegeneration and that the maximum possibleuse should be made of the resourcesthat waste represents. Strong political willand commitment, together with publicsupport, are key elements in achievingthis goal. Because waste management inSweden is the responsibility of local governmentsa great deal of competence istied in with these governments as well.Centralised waste incineration was introducedas early as the 1950s in Sweden,with extensive development during the oilcrisis in the 1970s. This gave Sweden anadvantage in the development of wasteincineration know-how and technologyinternationally. In the mid 1980s knowledgewas gained about the extent of dioxinemissions from these processes. Thislead to a moratorium on new incinerationplants which in turn lead to the developmentof advanced and secure flue gastreatment technologies to reduce dioxinsand other environmentally hazardoussubstances to a fraction of previous levels.With a unified political ambition to eliminatelandfilling of waste, the disposal ofcombustible and organic waste on landfillwas prohibited in 2002 and 2005 respectively.This further triggered the introductionof alternative systems and methodsfor waste treatment.waSte – a reSourceToday more than 20% of the domesticheat demand in Sweden is covered by incinerationof MSW and waste-to-energyhas been recognised as a renewable energyresource. Carbon taxes, high landfill disposaltaxes and also tough recycling andrecovery targets have been widely acceptedby the public.

352.1SUCCESS CASE ’ESKILSTUNA MUNICIpALITy’ThE MOST ENVIRON-MENTALLy FRIENDLy SWEDIShMUNICIpALITy <strong>IN</strong> 2012In 2012, the City of Eskilstuna was awardedthe prize, ‘Most Environmentally Friendly SwedishMunicipality’, a position reached by having abroad and systematic approach to environmentalprotection and sustainable development. TheMunicipality’s goals for sustainability are strategicallyand systematically monitored and reviewedto secure long-term development and results.StrategieS for SuStainabilitybecome a realityIn everyday life these strategies are transformedinto concrete systems and facilities, such as theunique optical sorting of household waste makingsource separation an easy task. Each wastetype is disposed in a type specific coloured bagand can then easily be disposed of in the samerubbish bin. An optical sorting system based onthese coloured bags then enables the productionof a clean organic fraction for the production ofbiogas and also increased levels of recycling.Another example is the public transport systemwhere busses run on biogas fuel only. Eskilstunaalso hosts the largest wetland for wastewatertreatment and more than 95% of the fuel forthe combined heat and power plant is biomass.The majority of these results are the outcome ofprojects initiated by Eskilstuna Energy & Environment,the municipally owned multi-utility company.But even more important, was the commitmentof the citizens who contributed by sortingtheir waste, by choosing to cycle instead of driveand by using less power for domestic purposes.

The majority of the productioncomes from large scale facilities. Smallscaleunits only represent 1% of the totalproduction. The main portion, 45%,of the biogas produced originates fromsewage treatment plants. Landfill gasrepresents 25%, and co-digestion plantsrepresent 20%. Biogas production fromindustry related processes represents 9%.In Sweden biogas is used mainly asa vehicle fuel, more than 50% with agrowth-rate of approximately 20% peryear. The gas is also used for local heating,district heating and industrial heatingprocesses and to generate power.Vehicle gas is made up of naturalgas (CNG), biogas (CBG) or a mix of thetwo and is frequently used to substitutepetrol or diesel. In addition to reducingemissions of carbon dioxide, vehicle gascuts emissions of nitrous oxides, sulphuroxides, carcinogenic substances and particulates.Because natural gas produces 25%less carbon dioxide emissions relative topetrol or diesel, it is also considered, bythe legislators, to be an ‘alternative vehiclefuel’, although not renewable.

Today, more than 60% of the demandfor household heating in Swedenis met by district heating. During the lastdecade the district cooling systems havebeen growing also and Stockholm currentlyhas the largest district cooling gridin the world.heat no longer waSted!Surplus heat from industrial processesare often seen as waste, however, thefundamental idea behind modern districtheating is recycling of surplus heat thatwould otherwise be lost. Examples of surplusheat are; heat generated in powerstations, fuel refineries, incinerators andmany other industrial processes. Throughinnovative thinking, introduction of systematicprocesses, and the developmentof high-end technologies, expansion ofthe district heating and cooling systems inSweden has created a base for energy recoverycompetence and technology whichis recognized worldwide.Although other countries with warmerclimates may have less need for districtheating, the opportunities in utilising surplusheat and steam for other purposesare extensive.
