| Abstract | Growing awareness of environmental impacts has led to increased requirements for environmental information about seafood products. Moreover, frozen filleting catfish (Pangasius) product has been one of the most successful seafood products of Vietnam in term of export earner. This study is an attempt to evaluate and identify the environmental impact potentials of this product. To achieve this aims, Life Cycle Assessment (LCA) was applied to study the environmental loads of the product through its life cycle. LCA of a catfish processing Factory was performed on SimaPro 7.0, Eco-indicator 99 (H) V2.03/Europe EI 99 H/H method. The system boundaries under study include the transportation of raw fish to the Plant by barge, fish processing in the Factory and transport of final product to seaport by truck ready for exports and packing materials (corrugated cardboard, polyethylene) production stages as well as. The results showed that fish processing was the contribution to environmental impacts and road transport of final product by 20-feet diesel refrigerated containers was the second contributor in single score value. After identifying the significant environmental impacts of entire product life cycle, possible improvement actions were proposed and performed. The most contribution to environmental impacts of fish processing was ascribed to electricity mix production stage because fish processing in Plant consumed the huge quantity of electricity mix. Analyses for the same quantity of electricity generation, the electricity from coal and oil power plant were the most contribution processing. So, in scenario 1, replacement of electricity oil and coal by electricity hydropower and electricity gas turbine was possible. By doing so, climate change impact was reduced by 22.45% (0.66E-8 DALY); reduction of impact category ozone layer depletion was 45.12% (1.5E-11 DALY). In scenario 2, road transport (truck) mean was replaced by rail transport one (train). Consequence, reduction of ozone layer depletion was 61.53% (1.82E-10 DALY). Climate change impact was reduced by 36.46% (1.51E-8 DALY) In addition, in the third scenario, replacement of electrical compression chiller by absorption one driven by natural gas in cold store, by doing so, climate change impact was reduced by 84.26% (2.85E-10 DALY). Ozone layer impact category was decreased by 96.08% (3.76E-13 DALY). Among three scenarios, scenario 2 is the best choice in term of climate change impact and ozone layer depletion. It is clear that combination of three scenarios has had the best score. It was proposed that in some limitations, factory can perform scenario 2 or 3 or combination of these two scenarios. |
