3. Primary Tissue Information

4. Initial footprint

5. Stakeholder position • Municipality of Wageningen The municipality would like to make a transition towards a sustainable way of living by introducing state of the art technologies that would help create a circular metabolism • Since the municipality is a public authority, we believe that it should take its responsibility in being sustainable. A municipality has influence on many fields, therefore its position as mediator should be used to implement sustainable developments.

6. Action plan • In 2030, the municipality of Wageningen should firmly decrease its resource use and should depend mainly on self-providence • The first step is a project proposal for a small neighborhood that will help discover the opportunities and potential in terms of sustainable developments, innovations, public acceptance and other stakeholders’ cooperation • After this pilot project, experiences will be used to implement sustainable developments on a larger scale

7. Resource recovery • Energy • Water • Waste • Food • Transport • Nutrients N and P

8. Energy • Wind turbine • Ground-source heat pumps • Improved insulation and window glazing • Passive solar heating • Tariffs • Smart meters • Results: 100% clean electricity, 94% reduction of natural gas use, more efficient energy conservation and use

10. Water • Rainwater harvesting (~40500 L/year) • Use for: • Garden and greenhouse • Flushing toilets • Washing • Outdoor use (washing car etc.) • No grey water reuse • House still connected to tap water, as this is used for drinking and food preparation (and drought safety)

11. Rainwater Harvest Tank Diameter 1507mm Height 1665mm The tank is round.

12. Waste vegetables • Recycling • Composting • Biogas plant Biogas production for cooking • Composting can be used for growing vegetables • Biogas for cooking Waste from household Paper and Cardboard Glass Scrap Metals Plastic Packaging Kitchen, Organic and Garden Textile Wood • Composting • Produce biogas energy • Give it to charity • Reuse it • Provide E- Books to replace news papers and books • Can be reduced by: • Providing separated garbage • Will be collected every 3 days • Reuse Recycling will be done outside the tissue

13. Waste Biogas System Biogas system in the tissue Source: Agama Biogas System

14. Separate Garbage • Glass Waste • Paper and Cardboard • Plastic • Scrap Metals

15. Food • Greenhouse (2300m2) • Vegetables • Potatoes • Poultry (60 chicken) • Eggs • Meat • Fruit trees (30) • Apples • Pears • Cherries

18. Transport • Decrease car use • Biogas fuelled cars • Small electricity powered vehicles

20. Nutrients N & P recovery • Yellow and Brown water separating toilets • Yellow water - Urine • 50g/m3 – N • 10g/m3 – P • Concentrated brown water - Excreta • CH4 - 1m3/day

25. Social Implications • Many infrastructural changes: different sight • Common activities • Cooperation needed • Pilot project
