Recently adopted EU waste legislation and its implementation at national level could have 
a significant effect on some countries’ emission loads for municipal solid waste incinerators, 
according to a recent study. The study suggests that the effects of increasing  incineration 
over the next decade would be most profound for countries where incineration is currently 
only used on a small scale. 
 
 
 
 
 
 
 
In the EU there is a drive towards material and energy recovery, towards replacing landfill with recycling and 
incineration combined with energy production from waste. In 2008, there were more than 400 working municipal solid 
waste incineration (MSWI) plants in the EU and over 40 more will open by 2020.Figures from the Confederation of 
European Waste to Energy Plants (CEWEP) suggest that 380 plants are converting waste to energy. However, 
European waste legislation is implemented differently by national authorities and the degree to which municipal solid 
waste is incinerated varies strongly among countries. 
 
The study simulated greenhouse gas and cadmium emissions from MSWI plants at EU level and national level for the 
year 2020, as compared to a 2005 baseline, based on shifting waste management policy . By calculating potential 
emissions under four different policy scenarios, it provided an emissions range, rather than a definite value, for each 
country. The emissions only account for MSWI outputs - not reductions in emissions from other sources. Thus, the 
emissions reduction benefits from using energy from waste instead of landfilling waste, or replacing other energy 
sources such as carbon, have not been taken into account. 
 
For each of the four policy scenarios, it was assumed that policy could shift towards energy recovery or towards 
material recovery at the EU and national level. For instance, while EU policy might focus on energy recovery (including 
waste incineration), a country’s national policy might focus instead on material recovery (including recycling) or vice 
versa. The emissions range was calculated as the difference between emissions in the two most extreme scenarios: 
1) focus on energy recovery at both levels and 2) focus on materials recovery at both levels. 
 
In 2005, half of the 33 European countries included in the study had per capita GHG emissions from MSWI plants 
below 19kg CO2 (per country). By 2020, according to the researchers’ simulation, an (extreme) energy recovery policy 
focus at both levels could result in half of all these countries having per capita GHG emissions from MSWI plants 
above 195kg CO2. Cadmium emissions would be higher under the extreme energy recovery scenario compared to the 
opposing materials recovery scenario. This is because extreme energy recovery predicts that a higher proportion of 
cadmium-containing batteries would be incinerated, whereas under extreme materials recovery, more would be 
recycled. However, in 2020, under the extreme energy recovery scenario, emissions in only two countries would be 
higher than in 2005, which is due to effective emission abatement measures being applied.  
 
Any extreme shift in waste management policy is predicted to have the greatest effect on MSWI emissions in those 
countries where incineration is not yet well established. In Poland, for example, which in 2008 was incinerating less 
than 1% of its waste, the effect would be marked.  GHG emissions from incineration could increase by more than 300 
times their 2005 levels under the most extreme energy recovery scenario. However, this does not take into account 
reduced emissions from other energy sources or reduced landfilling. By contrast, effects on Switzerland, which already 
incinerates around half of its municipal waste, will be minimal. The most extreme scenarios simulated in the study are 
not expected to occur in reality, however, the methods the researchers developed provide a useful way to explore the 
range of effects that could be associated with policy shifts, and the potential for different countries to experience 
effects of different magnitudes depending on their existing policies. The researchers also point out the limitations of 
their work – perhaps most notably that the study focused specifically on emissions from MSWI plants and did not 
consider the wider impacts of waste policy changes.
