The Marituba Unit, located in Igreja Nova (AL), was designed in 1979 by the Carlos Lyra Group and serves seven municipalities. In the 90s, the construction of the Salvador Lyra dam allowed the implementation of linear irrigation techniques, increasing productivity. The unit focuses on the sustainable production of sugar, ethanol, electricity and sugarcane derivatives, meeting market standards and seeking continuous improvement. Production begins with weighing and analyzing the sugar cane, followed by pressing to extract the juice, which is analyzed to determine the soluble solids and sucrose content. Mineral impurities are also checked. The broth is then clarified with lead sub-acetate and filtered, and is subsequently analyzed to measure the sucrose content. The internship at the plant provided practical learning about laboratory and operational processes, covering several areas of the sugar and alcohol sector, highlighting the importance of the role of the chemistry technician in quality control and optimization of industrial processes.
