 Late 1800:
Cholera-epidemic - start of
municipal waste management
 1950’s:
District heating systems developed
 1970’s and 80’s:
Oil crises - waste is being used for
district heating

National target on food waste 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 of roles and responsibilities
Municipalities:
• Collection and treatment of
municipal waste
Citizens/households:
• Separation and
leave/transport
waste at indicated
collection points
Producers:
• Collection and treatment
of waste within the
Producers Responsibility
Companies/Indust
ries:
• Handling of own
generated waste
Benifits with public waste management responsibility
 Front runner position to develop
– Competence
– World class infrastructure
 Environmental and social benefits
 Ensures long term and holistic work
according to the waste hierarchy
Plans, regulators, permissions and supervision
National level



Parliament
 National environmental targets
The Swedish Environmental Protection Agency

Organisation and operation
Municipalities deal with their responsibility in different ways and
design their own waste management organisation
Organisation:
 About 50 % municipal companies
Collection:
 73 % outsourcing
(mainly to private companies)
Treatment:
 About 65% outsourcing
(mainly to municipal companies)
Owner-ship of waste incinerators

Public awarness - a success factor
Key messages and tools for motivation and
to facilitate collaboration:
– Communication
– Development of self instructive systems
– Feed back of the results and that ”what I do
matters”
– Emphasize on the waste holders
responsibility and participation
Waste prevention
 Long tradition of reuse through flea markets,
second hand, collection at recycling parks, etc
 Deposit fee system for bevarage
containers/bottles
 Foodwaste, textiles, electronical and
demolition waste in focus – goals proposed
 Largest challenge: decoupling between
generated waste and economic growth

Production of biogas and bio-fertilizer
 The most increasing
treatment method
 58 plants
 Energy recovery by the
production of biogas used
as a vehicle-fuel
 Recycling of nutritions to
farming-land by the
production of bio-fertilizer
During 2012, 353 GWh vehicle-fuel was
produced from foodwaste replacing about
30 millions liters of petrol. 725000 tonnes
biofertilizer is produced yearly in Sweden.

Digestate – certified recycling
725 970 tonnes of digestate was produced 2012
Nearly 100 % was used in agriculture as bio-fertiliser
Around 90 % of the digestate is certified
Generation of district heating and electricity
 Covers around 20 % of the
total district heating in
Sweden, equals the needs
of 900 000 homes
 Produces electricity
corresponding to the needs
of 250 000 homes
 Advanced and secure flue
gas treatment
 Most of the rest-products
can be recycled
Total energy production 2012:
District heating: 13 TWh
Electricity: 1,7 TWh
(including industral waste)
Energy recovery of waste
34 plants:
 Receiving 50 000 – 700
000 tonnes yearly (2012: 32
plants)
 Recovering yearly (2012: 32

Waste economy
Municipal waste:
 All costs covered by
municipal waste fees
(not by taxes)
 The fee is decided
by each municipal
board
 Non-profit
 Allowed to be
differentiated to
encourage source
separation for
recycling
Municipal waste
within producers’
responsibility:
 Costs covered by a
fee added to the
price of every
product
 The fee is decided
by the producers

 Government regulations, bans, and taxes, for
example:
 Tax on landfilling (since 2000)
 Ban on landfilling of combustible waste since 2002
 Ban on landfilling of organic waste since 2005

Aim with the new platform
To facilitate the export of
 Swedish knowledge about
waste management,
 products and services within
the waste sector,
through cooperation among
the public and the private
waste management sector.
A strategy based on cooperation
A network of actors in the public and private waste management
sector in Sweden:
- Municipalities/municipal companies
- Knowledge suppliers
- Technlogy suppliers
A strong Swedish platform with a unique mix of competences
