Waste to EnergyState - of - the - Art The Swedish Example The incinerated amount of waste hasincreased with 46% from 1985-1999,while the energy production has increased with 104% and most of the emissions have decreased with 95%-99%.
Waste to EnergyState - of - the - Art The Swedish Example The incinerated amount of waste hasincreased 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 Two Waste-to-Energy Plants Two landfills with separation and recyclingactivities, composting, production of wood chips, biodegradation of waste in special cells,recovery of landfill gas, landfilling, leachate treatment A pre-sorting plant for bulky waste Two Transferstations
Nine big Recycling Centres, open for the public • 30 Stations for the reception of householdhazardous waste • Collection of batteries • A special department for collection, storage and pre-treatment of hazardous waste • A separation and recycling plant for electric and electronical waste • A special system for collection of refrigerators and freezers
A special system for collection and incineration of health care waste • Remediation of polluted soils • A special plant for recovery of construction materials-bricks, windows etc • A special subsidiary for the separation and recycling of concrete, asphalt, gravel etc • A special subsidiary for the recycling of waste paper, cardboard, cartons etc • Sysav Development Ltd for R&D
Energy from waste 600 000 MWh energy produced annually from200 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 wasteincineration that is relevant in theEco Cycle Society and that is energyrecovery. Volume reduction is no more an objective even if it is an important parameter when comparing environ-mental impact.
Waste to Energy Conclusion: Incineration is only justified when the method is at least as favourable as other recycling or recovery alternatives.
