The Swedish Example
The incinerated amount of waste has
increased with 46% from 1985-1999,
while the energy production has
increased with 104% and most of the
emissions have decreased with
95%-99%.

The Swedish Example
The incinerated amount of waste has
increased with 79% from 1985-2001,
while the energy production has
increased with 2,57 times (157%) and
most of the emissions have decreased
with 95%-99%.
The Solid Waste Company of Southwest Scania
Owned by nine municipalities
Sysav is responsible for waste management,
treatment and recovery of solid household waste
and industrial waste in southwest Scania.

At the heart of the eco-cycle
Sysav´s motto:
The highest possible degree of recycling
and the lowest possible degree of
landfilling.

The Sysav Site
Sorting, recycling, composting and final
deposition of waste with collection of biogas
An example of integrated waste management,
with a combination of many methods for an
environmentally and economically correct
waste management
1. Two Waste-to-Energy Plants
2. Two landfills with separation and recycling
activities, composting, production of wood chips,
biodegradation of waste in special cells, recovery
of landfill gas, landfilling, leachate treatment
3. A pre-sorting plant for bulky waste
4. Two Transferstations
5. Nine big Recycling Centres, open for the public
6. 30 Stations for the reception of household
hazardous waste
7. Collection of batteries
8. A special department for collection, storage and
pre-treatment of hazardous waste
9. A separation and recycling plant for electric and
electronical waste
10. A special system for collection of
refrigerators and freezers
11. A special system for collection and
incineration of health care waste
12. Remediation of polluted soils
13. A special plant for recovery of
construction materials-bricks, windows etc
14. A special subsidiary for the separation
and recycling of concrete, asphalt, gravel etc
15. A special subsidiary for the recycling of
waste paper, cardboard, cartons etc

Energy from waste
600 000 MWh
energy produced
annually
from
200 000 tons
burnable waste
equivalent to
approx
70 000 tons
oil.
The new Waste-to-Energy Plant
Waste provides electricity
and heat
540 000 MWh of heat and
135 000 MWh of electricity
will be produced annually.
Waste to Energy
Conclusion:
Waste-to-Energy is an established
and well functioning method for
waste treatment and energy
recovery.
There will be an increased need for
waste incineration with energy
recovery.
Waste to Energy
Conclusion:
There is only one objective for waste
incineration that is relevant in the
Eco Cycle Society and that is energy
recovery.
Volume reduction is no more an
objective even if it is an important
parameter when comparing environmental impact.
Waste to Energy
Conclusion:
Incineration is only justified when
the method is at least as favourable
as other recycling or recovery
alternatives.
