In the present work, okra stalk (Abelmoschus esculentus) was chemically characterized to evaluate its appropriate
exploitation as a biorefinery feedstock. The chemical composition of this renewable lignocellulosic material yielding
maximum up to 120 tons per hectare was primarily determined by methods of wood chemical analysis. In terms of its
main organic constituents, its dry matter contained 65.0% carbohydrates (cellulose, hemicelluloses and other
polysaccharides), 20.5% lignin and 5.0% extractives. In addition, thermogravimetric analyses revealed that the content
of proteins and inorganics was 6.6 and 3.3% of the dry matter, respectively. Among the inorganic elements determined
by inductively coupled plasma atomic emission spectroscopy, calcium was shown to be the dominant one, with a
concentration of 17.2 mg/g, followed by magnesium, silica and potassium. The analytical data indicated that the stalk
of okra plant with a high crop yield would be a potential feedstock as such or together with other similar feedstocks for
versatile biorefinery purposes, including pulping and manufacturing of chemicals.
