other three scenarios. In particular, the net energy content of the
cotton oil (32,223 MJ/t) is multiplied by the weight of the oil itself,
equal to 0.285 kg in the Chinese company, obtaining a value of
9.183 MJ. For the USA company the energy content of the cotton
seeds was estimated in 8.7 MJ, with an oil seed production of
0.27 kg per 1 kg of cotton fibers. For the Indian company the energy
value of cotton seeds was calculated on the basis of a production of
1.6 kg of seeds per 1 kg of cotton fibers, which corresponds to
0.24 kg of cottonseed oil, equal to a net energy content of 7.733 MJ.
Table 4 summarized the main data obtained from the cotton
yarn producer.
