25
Climate Change
26
Production: Most important step
Glass mineral wool roll– 1 m2 – Climate Change ReCiPe – whole life cycle
Climate Change – production step
27
Glass mineral wool roll– 1 m2 – Climate Change ReCiPe – Production step
Climate Change – production step
28
Natural gaz contribution is high: - Production - Combustion
Glass mineral wool roll– 1 m2 – Climate Change ReCiPe – Production step
Climate Change – production step
29
Electricity contribution is low: French mix
Glass mineral wool roll– 1 m2 – Climate Change ReCiPe – Production step
Climate Change – production step
30
Binder: negative contribution ?
Glass mineral wool roll– 1 m2 – Climate Change ReCiPe – Production step
Climate Change
31
Binder: negative contribution ? NO – End of Life
Glass mineral wool roll– 1 m2 – Climate Change ReCiPe – Whole life cycle
Climate Change – production step
32
Raw material glass: High impact
Glass mineral wool roll– 1 m2 – Climate Change ReCiPe – Production step
Climate Change – Production step
33
Comparison with another plant: Raw material for wool has an higher contribution in plant A than in plant B. Why? More waste generated !
Glass mineral wool roll– 1 m2 – Climate Change ReCiPe – Production step – Comparison between two plant

5. Conclusion
34
Line waste efficiency – Climate Change
Amount of wastes in plant A = Plant B
35
Glass mineral wool roll– 1 m2 – Climate Change ReCiPe – Whole life cycle – Comparison between two wastes generation cases on the same plant
Line waste efficiency – Climate Change
36
- 3 %
Glass mineral wool roll– 1 m2 – Climate Change ReCiPe – Whole life cycle – Comparison between two wastes generation cases on the same plant
Base case– ReCiPe
37
Glass mineral wool roll– 1 m2 – ReCiPe – Whole life cycle
Base case – ReCiPe
38
Glass mineral wool roll– 1 m2 – Climate Change ReCiPe – Whole life cycle – Comparison between two wastes generation cases on the same plant
Line waste efficiency – ReCiPe
39
Higher reduction in categories where raw matter glass has an high impact

Electricity mix – Climate change
Only Photovoltaic (PV) electricity (storage system
and intermittence take into account)
41
Glass mineral wool roll– 1 m2 – Climate Change ReCiPe – Whole life cycle – Comparison between two electricity generation
Electricity mix – Climate change

Glass mineral wool roll– 1 m2 – Climate Change ReCiPe – Whole life cycle – Comparison between two electricity generation
Base Case– ReCiPe
43
Glass mineral wool roll– 1 m2 – ReCiPe – Whole life cycle
Glass mineral wool roll– 1 m2 – ReCiPe – Whole life cycle – Comparison between two electricity generation
Electricity mix - ReCiPe

Conclusion and perspectives
LCA = essential tool in an Eco-Design view
Details the environmental impact potential improvements
Avoids impact transfers from one category to another or between life cycle steps
Accurate environmental performance measures internal and external communication
ReCiPe : several impacts categories
Study other eco-Design strategy (other indicators, other ways, etc.)
