6. Amsterdam Water and Waste
We have only one earth….
Climate Change: CO2
Resources: shortage
Clean water
Biodiversity
9 billion people
Fair shair

8. Amsterdam Water and Waste
And..
We want to have choices
• In 15-20 years we have to replace 1000’s
of km sewage

9. Take-make-dispose
The world is changing
The Philosophy of Waternet and partners
• The Netherlands -> Circular in 2050
• 50% less resources in 2030

10. Amsterdam Water and Waste
Level of influence / possibilities to act:
• Within my own organization
• The influence in the chain

11. How to make it SMART: act local
Solutions: Act on a local level
Waternet climate neutral in 2020
In the chain: Social responsible purchasing

12. Paradigm shift
• From water to value
• From waste to value

15. Klik om de stijl te bewerkenProduction of green gas for transport,
fuel for 171 company cars of Waternet /
7.000 households

16. Result: Production
green gas at the
Amsterdam WWTP
• 12 million m3 biogas (8.4 million m3 green gas,
enough for 7,000 households = 25,000 people)
• The produced green gas is used for transport fuel
• CO2 is a by product and can be used for green
houses or chillers in lorries
• Additional benefits: cleaner air if green gas is
used in transport
• Cost reduction: extra income is about
7 euro ct/m3

Upscaling process
• Play Ground: De Ceuvel
• Living Lab: Buiksloterham
• Implementation: Amsterdam area
By participating in experimental

technological sense, but also in

24. Amsterdam Water and Waste
Combine it with the
Rainproof movement
• Integration of
• Movement of over 100 partners taking actions
to adapt to cloudburst events
• Shared ownership, raising awareness within
public and private sector
• Incorporated in 15 urban policy documents
• Capacity building: exchange knowledge and
instruments for others to act
• Many physical rainproof projects (public and
private)
• Copied example for other (inter)national cities
and initiatives

25. Challenge: Amsterdam
not cloudburst resilient
• Heavy rain due to climate change
• Increase of hard surface (paving
gardens, buildings & roads)
• Densification of the city
• Public and private need to take action
• Lack of awareness

26. Amsterdam Water and Waste
Examples on resource recovery
• Technology push vs market pull

27. Search for impact
• VOLUME,
• right QUALITY,
• CONTINUITY
• Search for ADDED VALUE in the chain
• Key player in innovation network
• VALUE PARAMIDE, as high as possible

28. Example
Phosphate
Phosphorus in waste water

29. Case: WWTP as a resource-plant
Solving operation problems leads to a new resource (struvite/fertilizer)
• Higher energy production Waste to Energy Plant
• Lower costs for maintenance
• Production 1000 ton P for fertilizer (3 ton/day)
(NH4)MgPO4.6(H2O)

30. Market perspectives Phosphate
• Where to apply? Direct use or raw material for fertilizer industry?
• Quality control
• Legislation End of waste
• Export? Germany, France, Developing countries?

31. Biomass from waterboards

32. Biomass: Opportunities
• Biorefinery: Fibres and Protein
• Biocomposite (board, building material)

33. For the near Future
Thevalue potential for the market
• Needed:
• stimulate recovery, upgrading and market
• A total approach by the Water Authorities -> from Technology Push to Market Pull
Focus on 5 Resource streams:
1. Phosphate
2. Cellulose
3. Bioplastics
4. Alginate
5. Biomass

35. Wrap up
• Dilemma’s / questions
• New business models need new players or players with a new mind set
• Waste -> Resources:
• Acceptance of the consumers (toilet paper as pizza box)
• Challenge: from idea to full-scale
• Pricing (Include the hidden costs)
• Legislation (waste)
• How do we create impact and how we organise it? Collaboration world wide / per continent?
• The political will / risk avoidance

36. Take-make-dispose
The world is changing
Include the hidden costs
• The Netherlands -> Circular in 2050
• 50% less resources in 2030

37. For the new happy generation
