| Résumé : |
Life cycle assessment (LCA) has become an important tool to quantify the environmental impact of products and industrial processes. It provides a full picture of the impact, in order to fine the best levers for improvement. This collaborative study analyses the environmental footprint from cradle to application to demonstrate the lower environmental impact of water-borne systems and identify the main levers for each technology. |

- Using hardener technology to reduce environmental impact
- Key impact categories
- System boundaries and calculated assumptions
- Reducing the carbon footpring
- Wind power offers greatest GWP reduction
- Lower CFP but impact on eutrophication
- Reduce waste and solvent emission
- Renewable energyputs raw materials in top spot
- Limitation of the study

- Fig. 2 : Carbon footprint breakdown - 1 m2 wood surface coated with clear-coat
- Fig. 3 : Photochemical ozone creation potential - 1 m2 wood surface coated with clear coat
- Fig. 4 : Influence of thermal energy source in the carbon footprint per m2 wood surface coated with clear-coat (EG :electrical grid/NG : steam from natural gas/renew : wind power
- Fig. 5 : Comparison of CFP per m2 wood surface coated with clear-coat with two systems and two different thermal energy sources for drying and curing (EG : electrical/renew : wind power) in comparison to the reference : 2K SB PU (EG)
