LCA Study
Here is an example of LCA study of an application in which our phenolic resin
is used.
This shows the effect of reducing CO2 emissions when phenolic resins for friction
material are replaced with biomass-based materials from conventional materials.
We use MiLCA, a globally recognized LCA calculation module for calculation. Please contact
us for more information.
