Circular Economy in site planning
Let us focus on Water and Soil cycling.

Green Infrastructure
EU Green Infrastructure: A strategically planned network of natural and semi-natural areas with other environmental features designed and managed to deliver a wide range of ecosystem services.
Water Technological Platform EU: Develop natural or semi-natural
areas for 1. Water purification, 2. Water storage and 3. Water safety. (nature-based engineering).
Environment Commissioner Janez Potočnik said: "Building green
infrastructure is often a good investment for nature, for the economy and for jobs. We should provide society with solutions that work with nature instead of against it, where that makes economic and environmental sense."

Nature-based flood defenses
programme Building with Nature: To make use of the natural dynamics in coast and shore protection (Ecoshape).
-multifunctional use of space -adds nature value -increases landscape attractiveness -CO2 fixation -is more sustainable -is adaptive -reduces costs
Hard solutions: tidal pools
Intermediate solutions: brushwood mats
Intermediate solutions: willow wetlands
Soft solutions: sand engine
Soft solutions: natural foreshores
Soft solutions Hybrid hard-soft mix Hard solutions
flexible and cost-effective less flexible, extra investment

Within or between project(s) linking of soil
and water functions.
Using sediments from waterways, lakes and delta areas for nature-based solution for flood defenses Closing soil cycle while providing water service.
Between project manipulation of water or soil quality
Prospective and knowledge gaps
• How to consolidate sediments at location? • What will the CO2 emission be? • How will it behave in future climate events? • What nature can we expect? • Will it be a valid business case for the
stakeholders? • Should we adjust our expectations?
