Smart sensors, self-configuration, operational flexibility, and automatic learning, among others, are technological attributes from industry 4.0 appliable to the essential oil extraction by the steam distillation process. These operations are recognized by their simplicity. Nevertheless, lack of automatic controls, process monitoring, and self-adjustment lead to uncontrolled extraction, poor yields, low quality of products. It occurs because of overexposure to high temperatures and overspending resources like energy and water. As far as capacity utilization is concerned, the optimized process is key to planning and managing the production activities.

Biosurfactants are active compounds capable of reducing surface tensions produced by microorganisms, having low toxicity and high biodegradability with possible production from renewable sources. This work aims at presenting a patents search on the biosurfactants production through fermentation, using waste as substrate. The methodology consisted of searching keywords and their blending, using the database of Derwent innovation. The search returned 15 patent registrations filed in the last 8 years. Of the 15, 10 orders are active. After analysis, 3 of the 10 selected patents showed strong adherence to the subject, describing the use of waste as substrates to produce more economical biosurfactants.

Microorganisms provoke neglected diseases. However, social factors intensified those affected by them. Macroalgae are photosynthetic beings that live in oceans. They are divided into three categories: green, red, and brown algae. These groups are known for having metabolites with various applications in biotechnology and natural products chemistry. The present work aimed to discuss, through bibliographic review, the applications of substances extracted from macroalgae to the treatment of forgotten diseases in Brazil. This research concludes that literature has studies focused on the presence and absence of these compounds, namely its qualitative aspects, in which pharmacological, pharmacodynamic, and reaction mechanisms fields of these bioactive constituents are described.

Agribusiness is a major generator of waste, which generates significant environmental impacts. However, these residues can have several applications, thus having added value. Among all fruits, the banana has the highest rate of consumption in Brazil, consequently producing large amounts of peel. This work aims to get and characterize the banana peel flour for further application in biofilm production. We performed the physicalchemical characterization of the banana peel and the flour by crushing and drying in an oven (60 °C/24 h). Subsequently, we wash and delignification the pulp for its extraction. The results obtained 43% of total fiber in the flour and, at the end of the delignification process, 1.45 g of cellulose. Therefore, the banana peel presents itself as a potential matrix for application in the production of biofilm.

This work aimed to evaluate the growth and cost cultivation of Chlorella sp microalgae in PA and commercial urea medium solutions compared to BBM standard medium. We cultivated the microalgae Chlorella sp in BBM, PA urea, and commercial urea media, evaluating their growth for 8 days. In addition, we appraised the cost of the culture media considering the quotation of the reagents and the mass used for pilot-scale cultivation (100l). It was possible to observe the similar growth of microalgae with urea PA and BBM. The use of urea PA as a culture media for microalgae has the potential to reduce the cost of the medium by 68%. Thus, the cultivation of Chlorella in urea medium represents an alternative to reduce the production costs of biomass from this microorganism.

Laboring with electronics involves difficulties and sources of error, which sometimes causes the malfunction of the equipment. It is necessary to carry out inspection activities to locate points of uncertainty, isolate them and test the system without their interference to recognize a source of non-conformities and solve it. The article presents the activities of electronic systems enclosed in a prototype, describing the faults detected and the improvements implemented.

The search for tissue regeneration has attracted a lot of attention due to its wide applicability, and great potential to solve several problems in advanced therapies. Currently, functional systems have been widely used as therapeutic solutions in the treatment of some skin diseases, whether chronic, acquired, or as a consequence of accidents and burns. It is possible due to the feasibility of releasing and/or acting in loco of some active substances with properties and characteristics very similar to human skin. In this sense, this work aimed to carry out a literature review research regarding the development of new biomaterials, including hydrated membranes composed of biopolymers such as keratin and bacterial cellulose.

The present paper discusses the presence of microorganisms in textile materials, especially in car seats, and the use of antimicrobial agents. We observed that the main agent between the user and the car's microbial system are the seats, due to the direct contact with the users. In addition, the environment in which the car is inserted, the type of car, and the seat fabric-type influence directly the reproduction of the microbial system. Microorganisms found in different parts of cars, especially in seats, could be potential threats to human health. Thus, to combat these microorganisms, it is necessary to study antimicrobial agents aimed at eliminating or inhibiting their reproduction and, consequently, promoting hygiene, ensuring the health and well-being of car users.

The emergence of geosynthetics changed many aspects of the project and construction of civil and environmental works. Due to the existence of a wide variety of products and the constant advancement in the development and dissemination of new technologies. These materials are applied in different engineering solutions, highlighting the possibility of using recyclable and biodegradable materials and executing geotechnical and environmental works ranging from the control of erosion to the protection of groundwater. In this context, this work presents a literature review on the use of recyclable and biodegradable materials as geosynthetic products, as well as their association with traditional geosynthetics for solutions in engineering works. The review was carried out through the platforms Google Scholar and Portal of Journals of CAPES, using keywords and Boolean connectors as descriptors. It is observed that there is a potential for the use of recyclable and biodegradable materials as geosynthetics. However, there is still a need for a careful assessment concerning the benefits, limitations, and impacts caused by the use of these wastes.

Cocoa (Theobroma cacao L.) is a fruit widely cultivated in the world, mainly because it is the natural material used in the production of chocolate. Cocoa husk corresponds to approximately 80% of the fruit and is the main residue of production involving this fruit. Therefore, studies have been carried out to reuse the cocoa husk, including the extraction of pectin, which is a soluble dietary fiber present in the cell wall of many fruits. The study aimed to extract pectin from the cocoa husk, presenting parameters such as acid concentration, temperature, extraction time and the quantification obtained. The results were compared with literature data regarding extraction from other sources. In the study, the yield of pectin extracted from cocoa husk using 0.086% citric acid at 90°C for 60 minutes was 10.75% for the epicarp and 5.75% for the mesocarp.
