Some facts• 880,000 inhabitants but expecting to grow up to one million in 2020
• City built on 14 islands
• 40% of area is parks and green areas (the world´s first national city park)
• Awarded the EU Green Capital Status in 2010
• The only global city to meet stringent the World Health Organization’s recommended air contaminant standards
• Among best cities to live in (health care, education, business environment, the number of sunlight hours, environment)
Do you Fika? A way of life in Sweden
• Fika as a noun refers to thecombination of coffee andsweet snack
• But Fika as a verb means the act of partaking in Swedish social life
• “I have learned, over a cup of coffee, for even a brief time to stop doing and to enjoy just being“ (Averbuch, The New York Times, 2013)
• Fika philosophy is also reflected in the Swedish approach to the environmental issues
Growing… But sustainably and environmental-friendly
• 30 major urban development project are currently under way (Hammarby Sjöstad, Stockholm Royal Seaport, etc.), plans to built 100,000 new homes by 2030
• The key question is how to reach balance between ensuring that all city services will meet the expectations and requirements of citizens, and, simultaneously, will not endanger both the city´s goal to become fossil-fuel free city by 2030 (2050) and energy efficiency?
• The City´s Environmental Programme and Stockholm City Plan=> employing sustainable energy solutions, crafting smart environmental designs adapted to future climate change, and support ecological means of transport
A case study of Hammarby Sjöstad – the first environmental city district
• Based on a closed ecocycle where waste and energy use are minimized, and asmuch as possible isrecycled and composted
• Half of the overall energy is produced by residents themselves
• Renewable fuels, re-use of waste heat, production of biogas from wastewater, household energy efficiency (insulation, solar panels, green roofs, water-saving shower heads) => up to 50% reduction of energy consumption
Towards zero waste• 99 % of all household waste is recycled, ecologically burned,
composted or reused, 1% of waste ends up in landfills
• recycling stations are as a rule no more than 300 metres from any residential area
• Most Swedes separate all recyclable waste in their homes (80% of Swedish population support stringent ecological programs)
• A vacuum-powered tubes to transport and collect recyclables and garbage
Waste to Energy• 50% of the household waste is burnt to produce energy at incineration
plants– The Högdalen co-generation plant separates combustible waste as an energy
source in electricity and district heating production
• The remaining ashes which do not burn are sifted to extract gravel that is used in road construction
• The smoke from incineration plants consists of 99.9 per cent non-toxic carbon dioxide
Waste to energy • Sweden has developed a large capacity for efficient and profitable
waste treatment (imports 700,000 tonnes of waste from other countries)
• Re-using materials or products means using less energy to create a product, than burning one and making another from scratch
• Stockholm households keep separating their newspapers, plastic, metal, glass, electric appliances, light bulbs, batteries, and food waste
• Newspapers are turned into paper mass, bottles are reused or melted into new items, plastic containers become plastic raw material; food is composted and becomes soil or biogas through a complex chemical process
District Heating System
• Heating plants burn climate-neutral fuels (biofuels, household waste) and produce heating and electricity together (90% of the fuel´s energy can be utilized)
• Accounts for almost 80% of total heating needs
• Due to the system, emissions ofgreenhouse gases have decreased by 40% since 1990.
Transportation in Stockholm• The key requirements: a high level of mobility and a low emission level
• Congestion charge (up to 10 USD per day) => reduced emissions ( and traffic (around 20%)
• Rubbish trucks and all inner city buses are run on recycled electricity, ethanol or biogas
• A special focus on cycling and walking mobility
• 80% travelers in rush hours use public transport
• Walking and cycling comprising 39% of all trips during weekdays, using cars account for 30%
• Why Stockholmers are willing to travel by public transport?! =>
1. Public transport accessibility is exceptionally high
2. Persuasive “pull“ factors (bus corridors, bus rapid transit system, multi-modality, etc.)
3. Aesthetics of public transport => “the world´s longest art gallery“ decorated with sculptures, paintings, engravings,
etc.
Boston and recycling• Residential recycling rate is only on 20% (80% in San Francisco, 60% in Seattle)
– Food waste comprises 25% of the current waste stream
• 100 cities have curbside collection of organic waste => Boston has only a voluntary programs
• Insufficient recycling capacity (the only one industrial scale composter in Marlborough)
• Does city of Boston (Massachusetts legislation) do enough to scale up recycling rate?
• “Chicken-and-egg“ problem in Boston: cannot begin a massive organic waste diversion program until there is capacity to process it, no company will build a new digester without a guarantee of volume
Boston and recycling
• But thing are moving up! =>
• The Massachusetts Commercial Food Waste Bill:
– apply to all institutions producing more than one ton of food waste per week (1,700 public institutions)
– The new legislation enforces to donate the edible food, ship it to an digestion facility, or use it as animal feed
– Converted to the law on October, 1, 2014
• State’s overall waste-reduction plan: aims to reduce waste streams by 80% by 2050
