  1. LCA of herring - a case studyNordic Network on LCA of FishRoskilde 18-19 November 2002 Per Christensen Aalborg Universitet

  2. Steps in the herring case • 1997 : First assesment. Based on EDIP. Used Excell for calculations. 3 effect-categories • 2000 : Other assessment. Other fishproducts - mackerel and mussels. Based on EDIP but using SimaPro. All effect categories • 2002 : Second assessment on Herring. Plaice and cod.

  3. Glass of pickled herring on 580 gr net weight Herring is 205 gr. Marinade is 354 ml. The rest is onions and spices Functional unit

  4. Traditional technical and economical allo-cation is used (so far) : Offal for production of fishmeal Cogeneration of heat and electricity System-expansion is used for some new cases in order to see how it works out Allocation

  5. The first LCA on herring The environmental effects from the life cycle of a glass of pickled herring when fishing with trawl or seine

  6. Hot spots in the lifecycle • Environmental regulation has focussed on the emission (of waste water) from fish processing industries • Often vi find “hot-spots” other places in the lifecycle (fishing - energy usage - sugar) - also because water savings and cleaner technologies have been implemented in the industries

  7. Normalised effectpotentials when using seine

  8. Normalised effectpotentials when using trawl

  9. New hot spots in the lifecycle • Anti-fouling paints are very important (TBT, copper). Underlines the importance of fishing • Production (melting) of recycled glass (oil and benzene)

  10. Fuel consumption for species / species groups in the Danish fishery in 2000

  11. Fuel consumption per kg caught fish for different fishing gears in year 2000. Allocation is avoided by system expansion

  12. Estimated consumption of anti fouling agents for different species / species groups in the Danish fishery in 2000

  13. Problems facing us ! • Environmental effects - toxicity - from chemicals hijacks the conclusions • Avoiding allocation ? • Many problems using databases and software. The validation is not good enough!
