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%.


16/29

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 highest possible degree of recycling

and the lowest possible degree oflandfilling.

At the heart of the eco-cycle

The Sysav SiteSorting, recycling, composting and final

deposition of waste with collection of biogas


22/29

An example of integrated waste management,with a combination of many methods for anenvironmentally and economically correctwaste management

1. Two Waste-to-Energy Plants

2. Two landfills with separation and recyclingactivities, 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


23/29

5. Nine big Recycling Centres, open for the public

6. 30 Stations for the reception of householdhazardous waste

7. Collection of batteries8. A special department for collection, storage and

pre-treatment of hazardous waste

9. A separation and recycling plant for electric andelectronical waste

10. A special system for collection ofrefrigerators and freezers


24/29

11. A special system for collection andincineration of health care waste

12. Remediation of polluted soils

13. A special plant for recovery ofconstruction materials-bricks, windows etc

14. A special subsidiary for the separationand recycling of concrete, asphalt, gravel etc

15. A special subsidiary for the recycling ofwaste paper, cardboard, cartons etc

16. Sysav Development Ltd for R&D

The new Waste-to-Energy Plant

Waste provides electricityand heat

540 000 MWh of heat and

135 000 MWh of electricitywill be produced annually.


27/29

Waste-to-Energy is an established

and well functioning method forwaste treatment and energyrecovery.

Waste to Energy

There will be an increased need forwaste incineration with energy

recovery.

Conclusion:


28/29

There is only one objective for waste

incineration that is relevant in the

Eco Cycle Society and that is energyrecovery.

Conclusion:

Waste to Energy

Volume reduction is no more an

objective even if it is an importantparameter when comparing environ-

mental impact.


29/29

Incineration is only justified when

the method is at least as favourable

as other recycling or recovery

alternatives.

Conclusion:

Waste to Energy
