3 Zero Waste in Borås, Sweden Why not in your city? 1. Technical solution of the city? 2. Key factors to success? 3. Management? 4. Future challenges? Long development toward zero waste in Borås The first planning of biogas plant 1940 Investigation and planning 1986 Start of source sorting in 3000 households years planning Full scale sorting with optical sorting system 1991 Anaerobic digestion and composting 1995 Interimstorage of hazardous waste 1998 First collecting vehicle run with gas 2002 Waste plan First public gas station opened 2003 New digestor ready 2003 New incineration plant ready 2004 First bus inside the city run on biogas buses inside the city run on biogas 2008 A second new gas station for private cars 2009 All 59 buses inside the city run on biogas 2010 A third new gas station for private cars 2011 Planning for a new energy complex 2011 District heating District cooling Biogas Hydropower Waste management Producer of Electricity Services within waste management and effective energy use 3

4 Borås Energy and Environment Founded 1891 City of Borås Turnover ~140 million dollar ~ 220 employees Landfill reduction in Borås Today Landfilling ~0 % Recycling 27 % Biological treatment 30 % Incineration 43 % 4

5 Municipal waste landfilling in Europe (2009) Waste landfilled (%) Belgium Bulgaria Czech Republic Denmark Germany Estonia Ireland Greece Spain France Italy Cyprus Latvia Lithuania Luxembourg Hungary Malta Netherlands Austria Poland Portugal Romania Slovenia Slovakia Finland Sweden United Kingdom Iceland Norway Drivers for the waste management in Europe & Sweden 1991 Municipal waste treatment plan 1994 Producer responsibility 1998 The local investment program (LIP) 2000 Landfilling tax (~ 27 EUR/tonne) 2002 Landfill ban on combustible waste 2005 Landfill ban extended to include all organic waste 2006 Landfill tax increased for the 3rd time (~ 47 EUR/tonne) 2006 Incineration tax (~ 8 47 EUR/tonne) Landfill reduction in Borås Today Landfilling ~0 % Recycling 27 % Biological treatment 30 % Incineration 43 % 5

6 We have developed our recycling model Technology Social aspects Economy Deposits for recycling PET & Aluminium Deposits for recycling PET & Aluminium Recycling of PET: > 83% Recycling of Aluminium bottles: > 87% Recycling of glass bottles: > 90% 6

7 Recycling of other materials (no deposit)! Collection of packages and papers Paper packages Newspaper Metal packages Hard plastic packages Batteries Glass (no colour) Glass (coloured) and other wastes (odd and big size)! Landfill reduction in Borås Today Landfilling ~0 % Recycling 27 % Biological treatment 30 % Incineration 43 % 7

8 Households In Borås: Source separation in black and white bags Toward Heat for households Toward Biogas For cars and buses Biological wastes treatment ~70% Biogas (Methane) Digestor (>3,000,000 m3/year biogas) Direct composting? No, thanks, too low prices! (It is Wasting the materials ) ~30% Biofertilizers 8

9 Households In Borås: Source separation in black and white bags Toward Heat for households Toward Biogas For cars and buses Combustion of Wastes Combustion of Wastes 9

10 Products Electricity (132 GWh) Steam turbine Heat (632 GWh) District heating network Chill (10 GWh) District chilling network Heat pump, COP 2.5 Absorption when excess heat available, COP

12 University of Borås School of Library and Information Sciences School of Engineering School of Health Care Sciences School for Education and Behavioural Studies School of Business and Informatics School of Textiles Library Central Administration Strategic research areas The research activity at the University can be divided into six major fields: Textiles and fashion Library and information science Resource Recovery Teacher education and education work Integrated nursing science Business and IT Industrial Biotechnology (Two year master) Resource Recovery two international master programs Prereq: Features: BSc in Chemical engineering or chemistry Industrial application of biotechnology for a sustainable development Sustainable Technology (Two year master) Prereq: Features: BSc Engineering or chemistry (chemical, industrial, electrical or civil) course in thermodynamics Resource management andrecovery of energy and material resources Hans.Bjork@hb.se 12

13 Resource Recovery PhD program A multidiciplinary PhD program with specialities in: Biotechnology Polymer technology Energy technology Simulation technologies Hans.Bjork@hb.se University Research Profile Resource Recovery Wastes and by products (Municipal, agricultural, forest, industries) Social aspects Conversion to energy Chemical processes Biological processes Material Recycling Logistic optimization Chemicals Biopolymers Chill Electricity Heat Diesel Gasoline Biogas Ethanol Metals Plastics Papers Glass Sustainable Society Hans.Bjork@hb.se International collaboration 13

14 Waste Recovery in Southeast Asia, Africa and Brazil What to do? Educate on the problem and solutions (Sweden and here): Students, children, public awareness Give visions to decision-makers (meetings and visits to Sweden) Help or do environmental review & master planning: Study current situation Put realistic goals and milestones, Implement the individual projects: Start with the pilots and small scales to make good example 14

15 Some examples of international works Network Waste Refinery Indonesia and in each city e.g. Waste Refinery Palu Waste Recoveries in Brazil (Macae, Fortaleza, Sobral) 15

16 Educational exchanges and research (MSc & PhD students, and Postdocs) Learn from Borås and start research at UGM on Biogas Environmental review & Analysis of the current situation (Indonesia, Iran, etc) Waste management system Impact on the environment Organization Legal and other requirements Social aspects Economic situation 16

17 Waste sorting (social and technical works in Indonesia) Biogas Pilot Plant (indonesia & Brazil) Fruit wastes Car fuel or Electricity Pilot plantbiogas Yogyakarta Indonesien 4 ton fruit waste/day 550 kwh/day electricity Reduced amount of greenhouse gases 2716 ton CO 2 /year The total cost for the plant: US dollar 17
