3 THE INDUSTRIAL SYMBIOSIS The Industrial Symbiosis at Kalundborg is a resource and environmental network, consisting of twenty-some bilateral, commercial agreements between five industries, two waste handling companies and the utilities department of the municipality.

4 Industrial Symbiosis Industrial Symbiosis was relatively new in the 1960-ties and is common know-ledge to-day. The systematic use of the Industrial Symbiosis concept as i Kalundborg is still not common practise in other industrial parks. Not in Denmark or world wide.

5 WHY KALUNDBORG? The industrial potential existed: Several large industries Limited physical distances A good fit The economic incentive existed There were no legal barriers The communication was good The Symbiosis Activities Kalundborg Symbiosis Institute 5

10 Industrial Symbiosis What has been achieved? Environmental aspects Economic aspects Social aspects The Symbiosis Activities Kalundborg Symbiosis Institute 10

11 Environmental aspect Resource savings. Examples: Ground water... 1,9 mill. m3/year Surface water 1,0 mill. m3/year Natural gypsum. 200,000 ton/year Oil 20,000 ton/year Reduction of NOx and SOx emissions. Reductions of COD and BOD emissions. The Symbiosis Activities Kalundborg Symbiosis Institute 11

12 Environmental aspect Future potential savings: Additional water savings of > m 3 by recycling of steam condensate CO 2 reductions through efficient use of energy surplus and increased use of bio-mass as secondary fuel Involve SME s (non-members) in the symbiosis network increase energy, waste and rawmaterial efficiency The Symbiosis Activities Kalundborg Symbiosis Institute 12

13 Economic aspects Economic Results: Total investments in 18 projects: ~ 75 mio. US$ Annual savings: > 15 mio. US$ Total savings until 2000: ~ 180 mio. US$ The economic results is much better to-day! The Symbiosis Activities Kalundborg Symbiosis Institute 13

14 Social aspects Examples of spin-off effects: Establishing of the Industrial Development Board of the Kalundborg Region Increased collaboration between neighbour municipalities in the region Collaboration in other issues, such as safety, training, human resources Added benefit to establish new production facilities in Kalundborg The Symbiosis Activities Kalundborg Symbiosis Institute 14

15 Long Term Potential Improve the Kalundborg results Extend the Symbiosis Network to other regions in Denmark New innovative symbiosis projects e.g. use of alternative energy sources (biomass biogas solar and wind) R&D in new technologies for improved synergy and ZERO waste. Export of experiences and know-how world wide The Symbiosis Activities Kalundborg Symbiosis Institute 15

16 What makes Industrial Symbiosis a success? What is needed to implement, successfully, symbiosis among private industries? Awareness Willingness Feasibility The Symbiosis Activities Kalundborg Symbiosis Institute 16

17 Lessons learnt Systems makes it possible People makes it happen! The Symbiosis Activities Kalundborg Symbiosis Institute 17
