SUMMARY:

The growing concern with issues involving, especially, the disposal of waste, whether urban or industrial, has led researchers to seek sustainable, innovative and economically viable solutions. The conversion of these wastes into products
of high added value represents an important alternative in solving the problem. In this work, the brewing industry residue, rich in malt, was used as a source of
biomass for biochar production, through hydrothermal carbonization carried out initially only with water at different temperatures, 160 ºC, 180 ºC and 200 ºC. Both biochar and biomass were characterized by several techniques in order to enable the determination of their main properties and their potential applications. Preliminary results of thermogravimetric analysis reveal that there was the formation of hydrochar and its mass loss events are greater as the carbonization temperature increases, in infrared spectroscopy (FTIR) the presence of vibrational bands characteristic of the carboxylic groups (-C =O), and vibrations of -C=C that correspond to the aromatic carbonaceous structure of the hydrochars, the decrease of hydroxyl groups (-OH) evidences the decrease of the H/C and O/C ratio. The hydrochars showed a low surface area, from 2.439 m 2 g -1 to 8.739 m 2 g -1 , which can be
Augmented through activation processes in acidic or basic medium depending on your application. The next stages of the work are the continuation of the characterizations of Biomass and hydrochar and the synthesis of biochar by means of pyrolysis.
