Eco-Efficient Economy in Sweden Warsaw, September 2010 Gunnar Haglund Embassy of Sweden, Warsaw 606 28 89 57 gunnar.haglund@foreign.ministry.se
The Oil Crisis in 1973 1973 1973 Today Sweden is almost completely independent of oil, gas and coal imports for the production of heat and electricity (apart from transports). - How did it happen? Sweden doesn t have any oil, gas or coal supplies of its own...
Energy Saving and Energy Efficiency in Sweden 1980-2006 180 GNP Index 1980 = 100 100 End use of energy 60 Energy/GNP = higher efficiency 1980r. 2006r. The cheapest energy is the energy never produced nor used!

The lesser waste the better, but... Municipal waste in Sweden in 2008 4 731 660 ton of household waste Each Swede produces 511 kg of waste per year 3% deposited (140 250 ton), and 97% recycled... 1% - hazardous waste (43 320 ton) 35% - material recycling (1 657 840 ton) packages (metal, glass, plastics, paper), makulatura, metal, electric and electronic waste 12,5% - organic waste biologically processed (597 280 ton) 48,5% - waste-to-energy (incineration) (2 292 970 ton)
So what do the Swedes really do with their waste!?? We sort them at the source!
Packages with a fee are collected in the shops 33 cl - 25 gr 50 cl - 35 gr 20 gr duży 80 gr mały 40 gr 11 zł 9 zł
5800 Recycling Stations for packages and paper with service personnel The producers are responsible for packages The stations are situated where people live or close to supermarkets Batteries Hard plastics Metal packages Colored glass Glass Paper packages Newspapers, periodicals, handouts
A complement: sorting closer home Owners and housing associations organize
650 Recycling Centers for bulkywaste, hazardous waste, and electric and electronic waste (WEEE) with service personnel Bulky waste: furniture, toys, bicycles, children s carriers, garden waste etc. Everyone brings his waste on his own, with his car 1 400 000 ton of waste in 2008, i.e. 154 kg per person 5,3 million visits to the Recycling Centers in 2008
Furniture Refrigerators etc. Soil, stones, concrete TVs, computers Hazardous waste Scrap metal Car batteries Wood Glass Tires Wood Light bulbs etc. Newspapers Carton Asbest For incineration Plastics, metal, carton Not for incineration Not for incineration Scrap metal For incineration Wood Exit Entrance Recycling Center in Linköping
The rest of the waste is either incinerated or processed biologically The rest of the waste is collected at home or in the apartment blocks Most of this waste is incinerated making use of the energy content (48,5%). In this case the mixed waste is collected in one bag More and more (12,5%) waste is processed biologically. In this case the sorted waste is collected at the source in two bags: one for the biological fraction, a second one for the rest of the waste that is incinerated. Approx. 46 % of the municipalities (133 of 290) has a system for collecting biological waste at the source. Approx. 31 % of the municipalities (90 z 290) are preparing such a system. Goal of the Parliament = 35%, average result = 20%, the best municipality = 40%
Waste collection 3 Collection either with - garbage trucks or - underground, stationary, vacuum systems Source: ENVAC Water, sewage, electricity and heat are transported underground... Why not also waste? - Silently, cleanly, and worker friendly!

Out of the 512 kg of municipal waste that the average Swede produces every year only 20 kg is put on landfill 31 W2E Plants 20 kg Stockholm 15% of the heat Göteborg 30% of the heat Malmö 60% of the heat
Municipal waste >15% of the heat in the District Heating network!
Approx. 80% of the heat in the Swedish District Heating network, that is, about 40% of all heat is generated from energy sources that are not used in other countries or even literally wasted.
Swedish conclusions 1 Energy supply in Sweden has become more secure and independent. Mentioned energy sources are economic and profitable (in Sweden). They cut costs and boost competitiveness. Heat + Electricity = Co-generation/Combined Heat and Power The value of the waste equals at least the value of the energy generated from the waste.
Outcome assessment: Comparison between costs for fuel oil and district heating Heat cost, SEK/MWh 1400 1200 1000 800 600 Sweden: Comparison between heat costs from use of A: Light fuel oil (incl taxes, excl VAT, and 80 % conversion efficiency) and B: National average district heat price (in the cost level of 2009) A3: Additional heat cost from the carbon dioxide tax for fuel oil A2: Additional heat cost for energy tax for fuel oil A1: Heat cost for imported light fuel oil 400 200 0 1970 1975 1980 1985 1990 1995 2000 2005 2010 B: National effective average district heat price according to Statistics Sweden 46
Swedish conclusions 2 Municipalities with up to 20 000 inhabitants should invest in Heat Plants fueled with biomass. Municipalities with 20 000 do 100 000 inhabitants should invest in Combined Heat and Power plants fueled with biomass. Municipal waste should be utilized in municipalities with more than 100 000 inhabitants plus biomass.
District Heating in Sweden Functions in 570 cities, towns and villages Creates local employment Local self-sufficiency: 100% heat, and 60% electricity (70-80% in winter) Local production, local energy distribution
Biogas from municipal waste Sweden has a very small gas net, that s why bio-methane is used for municipal vehicles. In cities like Borås, Helsingborg, Linköping and Västerås (with about 100 000 inhabitants each) all buses and garbage trucks are fueled with such biogas. We get energy in the same time as we solve an environmental problem. Source: NSR
Swedish waste water treatment plants Energy from waste water Energy production: 3.100 GWh - Heat 2.500 - Biogas 600 Total energy usage: 930 GWh - Electricity 630 - Other 300 Öresundsverket, Helsingborg The average Swedish waste water treatment plant produces 3 times more energy than it uses
Don t waste the waste Biogas! The Swedish experience Use the biological waste from within a radius of 50 km. Build larger installations for at least 50,000 ton s of substrate, with an energy potential of at least 1 MW of electricity and more than 1 MW of heat. Produce electricity and commercially use the waste heat in the district heating network.
Mix all kinds of substrates! The biological fraction of the household waste Waste from the fruit and garden industry Waste from dairies and slaughterhouses Waste from supermarkets: Best before Biological waste from restaurants, schools, hospitals etc. All kinds of biological waste from the agricultural sector Manure cows, pigs, chickens etc. Municipal and industrial waste water sludge The owner of the waste must pay for disposing of the waste. This makes the production of biogas from waste much cheaper than the production of biogas from grown substrates. You have to pay the farmer, who of course could grow and sell something else.

The conditions in Poland are great! 1. District Heating network and gas net 2. Big population = lots of waste 3. Big agricultural sector = lots of waste 4. A lot of land for growing energy crops
