Soybean residues were transformed through static pyrolysis carried out at temperatures between 250 °C and 350  °C. The gaseous fraction analysis showed that the gases emanated in the pyrolysis are mainly CO2 and CO. Furthermore, it was proved that this methodology constitutes a simple way to obtain useful carbons for the capture of pesticides present in an aqueous matrix. For example, the concentration of Chlorothalonil in a 7:3 water: acetonitrile solution decreases by 76-77 % through adsorption on the carbons obtained.
