2 Flanders integrates sustainable soil remediation into other policies Griet Van Gestel Soil Management Department, OVAM, Flanders, Belgium The 3rd International Conference on Sustainable Remediation Ferrara (Italy) September 17-19, 2014 Theme: Conceptual framework

3 OVAM promotes green and sustainable remediation OVAM integrates sustainable remediation in other policies

4 Three interrelated items

5 1. A practical example illustrates the need for integrated and sustainable remediation 1 1

6 Remediation costs of a blackfied exceed largely the value of the land Located in Grembergen polluted with MO, BTEX preliminary soil remediation plan only excavation is possible remediation costs (1,7 M EUR) > value of the land (± 100 keur)

7 The conditions of sale include principles of sustainable remediation redevelopment and remediation are integrated at least one storey below surface sustainable use of materials for buildings birds protection allow a corridor of 3 meter for a cycle path

8 The best candidate-buyer was selected using three criteria 1) the offered price 2) the way redevelopment and remediation are integrated 3) sustainability of the total project, especially integration in the landscape and sustainable use of materials

9 Future use of the blackfield: buildings for SMEs

13 2. A decision support system for remediation plans is expanded to redevelopment plans 2 2

14 Soil remediation is assessed with a green MCA, including a CO 2 -calculator A tool for BATNEEC evaluation of soil remediation plans is adapted for green and sustainable remediation. This MCA is provided in guidelines.

16 Soil remediation is assessed with a green MCA, including a CO 2 -calculator + environmental criteria local regional/global + introduction of a CO 2 -calculator + addition of a criterion production of non-recyclable waste

18 Assessment tools are needed for other phases in the process REMEDIATION SPECIFICATION & STRATEGY REMEDIATION TECHNICAL APPROACH SPATIAL PLANNING MCA PROJECT PLANNING (brownfield) SITE INVESTIGATION RISK ASSESSMENT REMEDIATION PLAN REMEDIATION WORKS AFTERCARE Ability to influence Sustainability

19 Development of a OVAM sustainability barometer What are the features? flexible, easy to use, optional applicable in different phases of the process integration of existing tools, as much as possible sustainable management of materials accounting for residual contamination

20 Sustainable construction of buildings methodology to choose the best construction material dynamic or modular construction selective demolition and dismantling

21 Development of a OVAM sustainability barometer What are the features? flexible, easy to use, optional applicable in different phases of the process integration of existing tools, as much as possible sustainable management of materials accounting for residual contamination

22 Development of a OVAM sustainability barometer The project was awarded to Witteveen + Bos. They will start from a tool, developed for their own use, emphasizing visualization.

24 Comparison of ambition (red) and project solution (yellow)

25 3. Policy on spatial planning integrates soil remediation 3

26 A green paper describes the vision for 2050 on spatial planning in Flanders

27 Flanders has a fragmented spatial structure

28 In the green paper the desired spatial planning and structure for Flanders is described 1. Metropolitan appeal 2. Diversity on a human scale polycentric urban regions vital countryside green-blue corridors 3. From unruly to resilient space

29 The Lansink s ladder principle needs to be applied to space

30 The new spatial policy plan is tried out in strategic areas

31

32 In a relatively short time more concrete plans will be worked out For 3 smaller zones, in a interactive way Strategic visions on the area for 5 thematic issues: mobility environment social and demographic aspects international connections and image sustainable soil management and sustainable use of materials
