1. A method for producing a non-petrochemical-derived conjugated diene polymer using an alcohol derived from a non-petrochemical raw material, comprising the steps of:
using an alcohol having an iron content of 0.0001 mg/L to 2 mg/L derived from a non-petrochemical raw material, bringing the alcohol into contact with a catalyst and carrying out heating to produce a conjugated diene having C4 to C12 carbons; and
polymerizing a monomer containing the conjugated diene to produce a non-petrochemical derived conjugated diene polymer.
