The SYSAV Case A Concept for the Reduction of Green House

The SYSAV Case
A Concept for the Reduction of Green House Gases
with Maximum Recovery and Minimum Landfilling
Håkan Rylander, CEO
South Scania Waste Company, Sweden
Maximum Recycling, Minimum landfilling
The Waste Problem can only be solved with
an Integrated Waste Mangagement
- with a Combination of Methods
Driving forces
Legislation – Laws, Directives etc
Environmental Awareness/Environmental Engagement
Education and Information
The Sysav Group handled 835 000
tonnes of waste in 2008
Household waste
Bulky waste
Industrial waste
Building and Construction waste
Hospital waste
Hazardous waste
Electronic waste
with
a Combination of Methods
Overall goal since 1974
Maximum recycling of material and energy,
with minimum of landfilling.

Sysav Biotec
• Treatment of 25 000 ton of food waste in 2010
• Plant for the pre-treatment and the hygienisation of food waste
for the production of a slurry
• Fermentation of the slurry in a separate bioreactor
• Upgrading of the produced biogas to a gas with fuel quality
• Production of biofertilizer
Composting of Green Waste
Composting at four Landfill sites
Compost
Waste provides heat and
electricity
Production of
• 1500 GWh of heat
• 250 GWh of electricity
SYSAV delivers 60 percent of the heat
demand in the cities of Malmö/Burlöv
3 tonnes of waste = 1 tonne of oil
Production of heat to the district heating net
550 000 tonnes equals to 60 percent of the heating demand in the cities of
Malmö/Burlöv

The Swedish Example
The amount of incinerated waste has
been more than doubled from 19852006,
while the energy production has
been quadrupled, and
most of the emissions have
decreased with 99%.
