The high cultivation of sugarcane in Brazil for the production of ethanol and sugar in the sugar-alcohol industry generates by-products that are of great importance within the sector and the production of the industry. Thus, it is important to know and study the use of these by-products, so that there is greater productivity and reduction of damage caused to nature. The by-products studied, which are obtained in the process of ethanol production and sugar production are: straw, bagasse, filter cake, molasses, carbon dioxide (CO2), yeasts and vinasse. These by-products can be used within the industry or in other sectors of the economy, also favoring the environment. This article presents the production process of ethanol and sugar and the by-products that are obtained and their subsequent use.

The sugar-alcohol industry has historically been an important Brazilian economic activity - it is estimated that today it corresponds to around 2% of the national GDP. However, alongside this economic abundance, there is one of the most precarious work activities still in force: the manual cutting of sugar cane. Normally, such activities are developed in the midst of serious problems in the work environment, which ends up vigorously affecting the health of each worker, whether physically or mentally. In view of the above, the main objective of the current work was to present in detail the adversities of the manual sugarcane cutting sector. Using a bibliographic survey, the research highlighted the main labor problems in the sugarcane cutting sector, in the context of the history of the use of sugarcane in Brazil as a raw material of great economic importance. The research results point to the ratification of the economic importance of the sugar and alcohol industry, but above all to the precarious working conditions in the manual cutting sector. Based on current literature, possible proposals for labor improvements for the manual sugarcane cutting sector were also presented. In conclusion, it became clear during the research that, even after 134 years of the end of slavery in Brazil, there are still situations similar to slave labor, with the manual sugarcane cutting sector being a very prone activity to such types of situations.

(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2022-11-22) Santos, Vilker Silva; França, Márcio Abreu de; França, Márcio Abreu de; Rocha, Martha Suzana Rodrigues dos Santos; Francisco, Kleyse Galdino
The sugar-energy industry plays a very important role in Brazil's history, from the early days until today, which makes it the largest producer of sugarcane in the world - data show that in the 20/21 harvest Brazil produced about 654.5 million tons. With the advance of technology over the past centuries, new equipment and vehicles have emerged with the purpose of improving the agricultural production system. However, in practice there are some pros and cons regarding the use of harvesters in sugarcane fields. In view of this, the present work had as its main purpose to report in a detailed way the impacts of mechanization in the sugar cane harvesting sector. Using bibliographical surveys, the research highlighted the problems and benefits caused by the mechanized harvesting system, besides presenting important data related to the sugarcane sector. The follow-ups of the work indicate great advantages in productivity and also to the environment, but they generate social impacts affecting the cutters. In conclusion, it became clear during the research that mechanization presents very important benefits to the economy due to the increase in production and also to nature by reducing the levels of toxic gases, however it also causes damage to the workers by generating unemployment.

The production of sugarcane has been an agricultural activity that faces several challenges, from those related to environmental issues, including economic ones, among others. This article aims to discuss and analyze the challenges related to environmental and economic aspects faced by sugarcane producers in recent times. The study is contextualized by a methodology that includes theoretical and field research. In the first one, we sought to identify theoretical aspects that deal with the panorama of this agriculture, referring to some points that deserve to be highlighted. In the field research, which is a case study, the vision oftwo sugarcane producers regarding the topic under discussion was evidenced. The methodology, already mentioned as theoretical and field, included the recording and analysis of ideas from theorists who deal with this topic and a questionnaire carried out with the two collaborators, through a Google form. The results obtained with this study were satisfactory, as many aspects of the context related to the panorama of sugarcane in Brazil were perceived, as well as the main challenges highlighted by the two producers regarding economic and environmental issues. The acquired knowledge was important to understand the subject in a deeper way.

According to work, we can see many workers suffering in the cutting of sugar cane, for not having knowledge about the rights of the Labor Laws. On May 1st, the CLT was enacted. The current situation is quite different from the year 1980. Brazil is one of the main consumers and exporters of sugar and ethanol, most of these workers are all with low education. The people who go to work in these plants go to improve the family, many of them migrate to the Southeast in search of a better condition for the family. The labor legislation does reduce as article 149 of the penal code, slavery can be characterized by four elements.

Sugarcane contributes to the Brazilian economy (NACHILUK, 2021), so, for the producer to obtain a quality cane, it is necessary that each stage of cultivation be done correctly. Given this bias, this study aims to review these steps, from planting to harvesting, providing information on the best paths that should be taken so that there is a quality final product and greater productivity through a literature review. At the end of it, it was possible to show that for a good result it is necessary to respect the recommendations made, from the moment of soil correction, to the choice of the harvesting system. In addition, such choices interfere with the sustainability of the sugarcane activity, since manual harvesting requires the burning of sugarcane straw, which causes the release of polluting gases, which contribute to the greenhouse effect.

Ethanol is the most used renewable biofuel in Brazil, being considered the cleanest fuel when compared to gasoline. Like gasoline, ethanol emits gases, but in a smaller proportion. In such a way, reducing environmental impacts and consequences for human life. However, in the production of first-generation (E1G) and secondgeneration (E2G) ethanol, the raw materials that stand out in Brazil are, respectively, sugarcane and its residues, which are bagasse and cane straw. Unlike the conventional process (E1G), the production of second-generation ethanol require more technology, as additional steps are implemented in the process, such as pretreatment and hydrolysis of biomass, in order to obtain ethanol with high quality and productivity. Therefore, it can be concluded that ethanol is an alternative to reduce environmental impacts and contribute to the country's economy. Thus, the objective of this work is to describe the production process of second-generation ethanol (E2G) by means of reading scientific articles, monographs and reliable websites. It can be concluded that bagasse is a high-value residue, which can be reused by the sugaralcohol industries to generate other products, such as second-generation ethanol (E2G) and electricity, without the need to expand the area of sugarcane plantations.

(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2022-03-18) Santos, Maria Laura dos; Cunha, Simonise Figueiredo Amarante; Cunha, Simonise Figueiredo Amarante; França, Márcio Abreu de; Cavalcante, Maria da Conceição Matos
The sugar and alcohol sector is responsible for producing sugar, alcohol, and other products through the use of sugarcane as raw material. The most used process before the sugarcane harvest is the burning of the cane field to facilitate the cutting and manual harvesting. The use of this practice brings with it some harmful consequences for both the environment and the health of society. Given the above, the present work aimed to understand the consequences of burning sugarcane straw, in addition to showing the risks caused to the health of the population during the harvest period and identifying the effects and changes caused to the environment. Given the study, it was found that the harvest method to be used is of paramount importance for the success of all production, and the mechanization of cutting brings more benefits to the soil and economy for the industry.
