The planting of sugarcane is related to the history and economic development of Brazil. This cultivation, since colonial times, has undergone tremendous agronomic and industrial development. The cultivation of sugarcane in Brazil kick-started a great business due to the main products obtained from this plant: sugar and ethyl alcohol (ethanol). The sugar alcohol complex is considered the most modern in the world, with Brazil taking a leading position in the production of ethanol. On the other hand, this sector is responsible for environmental impacts, both due to the intense use of natural resources and the large amount of waste generated, the latter being one of the main problems faced by the sugar alcohol industry. For this reason, the present work aims to present which are the by-products of the sugar and alcohol industry and their respective forms of use. Therefore, a bibliographic research was carried out, through articles, monographs, dissertations and theses, on sites such as Google Scholar and SciELO and it was observed that the reuse of by-products of the sugar alcohol industry can be of great interest, both profitable and socio-environmental

Objective: the present study aimed to determine the water requirement and calculate the weather risk for sugar cane in the Tabuleiros Costeiros region of Alagoas. Method: the water requirement of sugar cane was estimated using the Thornthwaite Water Balance (1948) and mapped using a geostatistical procedure. Results: it was found that there is significant variability in the water variability of soils in the region of Tabuleiros Costeiros de Alagoas, providing the existence of water surpluses and deficits throughout the seasons. Usually, the dry season occurs between the months of October to February and the surplus in the months of April to August. The spatialization of the water balance and the climatic risk classes suggests the existence of a pattern, with greater water deficit in the south of the study area, and greater water availability in the center north. Conclusion: the water balance of sugar cane showed that there are production limitations regarding climatic characteristics, which must be supplied with the use of adequate technologies, mainly from the rational use of water.

In Brazil, the sugar-energy industry plays an important role in the economy, as it is responsible for 2% of the Brazilian GDP. Among the products made available by this industry are sugar and ethanol. To obtain these products, it is necessary to extract the juice from sugarcane (the main raw material), which takes place in the milling stage. The materials from which the mill components are made must have some characteristics to make the milling process efficient. Studies on alternative materials are being carried out in order to reduce costs in the maintenance stages. One of the materials analyzed is Steel-Hardox, which has a positive cost-benefit ratio, as it has the characteristic of extending its useful life. This article aims to study and present the benefits attributed to the application of Hardox steel in the construction of mills where the use of Hardox steel demonstrates that it has the potential to cause a reduction in downtime for maintenance, contributing to a positive cost-benefit relationship, since that with fewer stops there is a reduction in production costs.

It is known that with the need for independence from oil and the search for fuels that were less polluting, the Proálcool was created, with the objective of encouraging the production of ethanol. Thus, ethanol is known to be a sustainable fuel alternative, in which it is generated from renewable sources. However, it is observed that during the production of ethyl alcohol some impacts to the environment are triggered. Therefore, this work aimed to analyze, through a literature review, the environmental impacts caused during each stage of agricultural and industrial production of ethanol. Therefore, impacts such as reduction in soil quality, soil and water bodies pollution by the exacerbated use of pesticides and fertilizers, in addition to atmospheric pollution and loss of biodiversity resulting from the burning, were identified, finally, soil and water pollution were also found due to incorrect disposal or uncontrolled use of residues and effluents from stages of the industrial process of manufacturing ethanol.

(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2021-12-17) Costa, Daniel Rodrigues de Oliveira da; Rocha, Martha Suzana Rodrigues dos Santos; Rocha, Martha Suzana Rodrigues dos Santos; Cunha, Simonise Figueiredo Amarante; Santos, Taciana do Nascimento
Simulation within the industry consists of defining, thinking about formulating, developing a functional specification, which cannot be applied in different situations. This work presents, through a literature review, the importance of simulation for the sugar and ethanol industry and addresses points for this industry, with an increasingly fierce confrontation by the productive sector in the globalized market. The method can be a powerful ally, including many automation and control benefits of all methods of global leveling up and expansion in efficiency parameters. A complete automated system generates a high degree of investment, but provides long-term benefits. It appears that most of the tools produced have already adopted alternative methods of using resources, equipment and planning and process control needs aimed at optimizing processes and products. It is expected that the method will be formalized within the sugar-alcohol industry, so that the procedures and processes are systematized in the manipulation and transformation of, helping to strengthen the production planning manipulation methods, decisions in the information manipulation process work tool option.
