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 tires 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.

Remark

  • CO2 emissions and reductions are only for resin in tires
  • These data are representative values based on conditions in the tire production process and are not guaranteed.
