Crystal sugar plays a central role in the Brazilian sugar-energy industry, requiring rigorous quality control to ensure purity, stability, and compliance with the standards demanded by the food, pharmaceutical, and export sectors. Considering that operational factors directly affect the physicochemical parameters of the product, this study analyzes how these indicators reflect the efficiency of the production process. The objective was to evaluate the importance of quality control and identify the influence of ICUMSA color, polarization, moisture content, ash content, reducing sugars, sulfite, and dextran on the final quality of crystal sugar. The methodology was based on a bibliographic review using scientific articles, technical standards, ICUMSA and MAPA documents, as well as the description of analytical methods used in the sugar industry, including spectrophotometry, polarimetry, calcination, oven drying, titration, and chromatography. The results demonstrated that ICUMSA color is directly influenced by clarification efficiency and thermal control; polarization reflects sucrose purity; moisture determines storage stability; ash content indicates mineral impurities; and reducing sugars increase due to thermal or microbiological sucrose degradation. It was also verified that sulfite residues depend on the rigor of chemical treatment during juice clarification, while dextran is associated with cane deterioration and negatively affects crystallization. It is concluded that quality control of crystal sugar is a strategic step in industrial management, enabling deviation detection, process optimization, and the assurance of a final product that meets national and international standards. The integration of laboratory analyses with modern technologies enhances operational efficiency and contributes to greater competitiveness within the sector.

The advancement of technology has provided the discovery of new drugs, in view of this, the manufacture of medicines has increased, and the consumption of medicines is constantly growing, which most of the time, after being expired or out of use, are discarded inappropriately. These residues, in turn, can be harmful to public health and the environment, which, even with sewage treatment, are not eliminated. The objective of the study was to know the destination given to expired or disused medicines in residences in the city of Penedo - AL. To this end, a diagnostic evaluation was initially carried out, seeking to collect information from the population of Penedense, regarding what would be the disposal of medicines, reverse logistics, if they had home pharmacies, among others. After data collection, the surveys pointed out that the lack of knowledge or an adequate educational awareness system is one of the main reasons for controlling the amount of erroneously discarded medicines and that only 9% of respondents have the practice of discarding drugs adequately, with antibiotics being one of the drugs most discarded, probably due to the withholding of prescriptions for acquisition. Soon after, interviews were conducted in pharmacies, analyzing whether they received such medications and it was proven that there are several collection points (private pharmacies and health centers) so that the community can dispose of them correctly, consciously, and sustainably.

Fabricação do cimento
(2022) Ferreira, Allyson Yan Farias; Nascimento, Raul César da Silva; Nascimento, Raul César da Silva; Cabral, Mirelle Márcio Santos; Santos, Wellinghton
Present work aims to show all stages of manufacturing and importance of cement. Cement is the most used material created by man in the world, so we can see that its existence is very important for the development of a society through the construction of basic sanitation, houses, schools, etc. Cement is linked to all this, where it is basically produced from limestone and clay materials, which are extracted from nature through mining, going to the industry by road transport until reaching the destination where it is stored in piles. This form of storage already makes a homogenization of the materials, transforming it into agical, then it is taken to the mills for crushing, reducing granulometry of agical until it becomes a fine flour called raw flour. This material is transported to be heated in the cyclone tower where it goes to a blast furnace, raising its temperature even more. Then there is the formation of clinker. This is because the high temperature causes a pre-fusion of raw flour, leaving it in the form of small stones that will later be crushed in a mill. At this stage, additives are added according to cement specifications, such as iron ore, blast furnace slag, gypsum, among others. Everything is ground and stored in silos so the product can be bagged or sold in bulk.
