A comparison of drivers behind implementation of source separation systems in

three urban pilot areas in Northern Europe

Hamse Kjerstadius, A.-K.Skambraks, M.Meier, M.Wuttke, T.Giese, Å.Davidsson


Background

Background:

• Source separation systems in an urban context have a great potential for increased sustainability of wastewater management.

Source separation systems…

…in urban city areas


Background

Background:

• We see a re‐newed trend of pilot areas with source separation systems.

• This trend mainly covers blackwater systems and is happening in Northern Europe(Netherlands, Belgium, Germany and Sweden).

• When initially investigated it seemed that the reasons for implementation differedbetween the areas.

So…. can we learn something about how we plan?

• What are the drivers behind this new trend of implementations?

• And what is the link to existing pilot areas?


Method:

• Drivers were taken from litterature but slightly adapted to a sanitationperspective.

Background Method

DRIVERS

GovernmentalNational law or national environmental goals.

Local area environmental goals.

Internal

Economy (decreased operation cost for the organization).

Internal organizational knowledge gain.

Market external

Development of marketable products.

National or regional financial support (external funding).

Non‐market

external

University research (possibility for field test and proof‐of‐concept installations).

Demands from citizens, media or NGO´s


Method:

• We contacted the largest pilot areas (identified project leaders).

• Questionnaire with open‐ended and close‐ended questions.

CONCLUSIONS

Background Method Results Conclusions


Conclusions:

• Earlier pilot areas were driven as proof‐of‐concept. New pilot areas with source separation systems are implemented to meet local environmental goals.

• The realized need for new systems come from within the sanitation sector. Demand from media/NGO was never expressed important.

• Source separation systems transcends water, waste and energy sectors. Increased stakeholder co‐operation is needed to overcome juridical issues.
