Experience from the Tekniska Verken

Global Sustainable
Cities Network (GSCN)
Experience from the Tekniska verken/City of
Linköping’s long term ownership and
management of municipal waste
MSW separation and collection, low-emission waste
incineration with recovery of energy (power and district
heating).

City of Linköping/Tekniska verken
group
• Tekniska Verken is 100% owned by the

• The City's goal: CO2 neutral by year 2025!
• Currently converting 600 000 tons/year of
waste into power and heat
• Biogas: 14 million Nm3 - 140 GWh
• Heat: 1 630 GWh
• Electricity: 676 GWh

MSW collection improvements in
Linköping
Between 1995 and 2001 Tekniska verken introduced
a weight-based system for curb-side collection
•
Property owners pay a fee based on weight
•
The system benefits households that are recycling
•
Has resulted in less collection of undesirable waste
and a higher degree of recycling
4
MSW collection improvements in
Linköping
In 2012 Tekniska verken introduced the
”green bag” for collection of food waste
•
Waste is collected in one bin with bags in two fractions:
•
•
green bags with food waste
common plastic bags for residual waste
•
Standard collection vehicles powered by biogas
•
A central optical sorting system
•
Has resulted in drier waste for incineration and a ”new”
fraction for the biogas production
So far 80% of the households have adopted the “green bag” and the food
waste fraction is collected with a high level of purity - average 94 %.

The journey continues towards a
CO2-neutral City by 2025
•
Tekniska Verken is now building an additional
incineration (CHP) plant
•
The fuel will be based on MSW and ISW
•
Will make the City of Linköping even less
dependent on fossil fuels
•
Planned to be in operation at the end of 2016
