Methods for producing bio-terephthalic acid and bio-isophthalic acid. Methods comprise a cycloaddition reaction to produce bio-4-methyl-3-cyclohexene-1-carboxylic acid, and bio-3-methyl-3-cyclohexene-1-carboxylic from bio-isoprene and bio-acrylic acid. An aromatization reaction produces bio-para-toluic acid and bio-meta-toluic acid from the bio-4-methyl-3-cyclohexene-1-carboxylic acid, and bio-3-methyl-3-cyclohexene-1-carboxylic. An oxidation reaction produces the bio-terephthalic acid and isophthalic acid from the bio-para-toluic acid and bio-meta-toluic acid.
