2. 1. Introduction
Solid waste management company to build new solid
waste management area near Lappeenranta (South
Eastern), Finland
Problem : current landfills not able to satisfy recent
requirement on the waste treatment
National waste plan requires recycling of municipal
solid waste from 50% - 70% by year 2005

3. New waste treatment area will be more centralized
waste treatment , less environmental (modern
technologies applied)
Waste : households, agriculture and buildings sites.
(Small amount hazardous pass through the plant)
current landfill use traditional process it leads to ugly
scenery, land value and property decrease and slowing
the development growth

4. Problem characterized as group MCDM problem :
- no preference information was available
- ordinal measurements for the criteria were
available.
New waste treatment area :
2-4 years : composting plant, facilities and landfills
20 years : operating time of plant
15 years : for the equipment
100 years will remain in location but re planning might
take place

5. 2. Legislation & Participation
• Finnish legislation, more towards “direct and
indirect” effects inside and outside of the territory
1 of the Finnish project.
• all citizens affected by the project , allowed to
participate in the EIA procedure to express
2 opinions (written)
• Supervisory group (stakeholders) are formed to
understand citizens opinion and public meetings
3 were held.

6. 3. Problem & Alternatives
six alternative , but only three of the alternative
discarded because:
Close to the settlement area
Too valuable to the scenery and nature
public meeting, they suggest four alternative for
waste treatment area (Herttuanvuori,
Kukkuroinmaki, Laapmaki and Ryosola)

7. Citizens • Negative view towards the plant effects : to
traffic, comfort , recreational use, effect
point of economy, decrease value in real estate and nature.
view Positive view new road improve the traffic connections
The
• Directly to the requirements of the legislation
planner’s • 10 points that effects that from the project
opinion
• 17 criteria, several criteria can not be measured
including positive and negative effect which indirectly
Criteria ranking produced by the experts approved by
supervisory

8. The ranking for the criteria based
on the benefit to the environment.
1– 2– 3– 4–
Best Better good worse

10. 5. SMAA – O : Stochastic Multicriteria
Acceptability with Ordinal Criteria
Developed for discrete multicriteria
problems
Based on exploring weight space in order
to describe the valuation that would make
each alternative the preferred one
SMAA –O method is descriptive.

12. 6. Results of analysis

13. • There are alternative ways for performing the
ordinal to cardinal scale mapping.
– Use identical mappings from full range {1,……,4}
[0,1], for each criterion or
– Choose the smallest sufficient range for each criterion
• For table 2 is the 1st approach- it shows that the
best place Kukkuroinmaki and Herttuanvuori
because they get high acceptability indicies (%).
• For table 3 is the 2nd approach-the result shows
that the acceptabilities of Kukkuroinmaki and
Herttuanvuori change slightly, but they still
remaind the only widely acceptable alternatives.

14. • These conclude that the result are not
sensitive to how the mapping was done
• After adding some constraints based on the
data collected, the analysis was repeated.
• After looking at the result, decision maker
(DM), chose Kukkuroinmaki alternative as the
forthcoming location of the plant.

15. 7. Discussion
1
The EIA process consider very good by the participants
2
Evaluation on the social effects was successful
3
4 alternatives analyzed in detail and elimination of 2 poor
alternatives were done
