Abstract: The printed circuit board (PCB) manufacturing and recycling process contains toxic metals, solvents, acids, dioxins and photolithography chemicals. Therefore, we are looking for PCB manufacturing methods with as few chemicals as possible and non-toxic base materials. The material that makes up the base is called laminate and the connections between the components occur through busbars (conductive paths). The possibility of replacing the laminate and busbar materials with thermoplastic polyethylene terephthalate (PET) and thermoplastic composites and carbon-based materials, respectively, was analyzed. The additive manufacturing (AM) process was
used to manufacture the PCB using PET and composite filament. The AM variant chosen was FDM (Fused Deposition Modelling), which allows the production of solid objects in thermoplastic materials. The objective of the research was to study the applicability of recycled
materials from commonly used FDM products for the manufacture of printed circuit boards (PCB), whosesubstrate is PET (Polyethylene Terephthalate) from bottle packaging and the fiberglass composite filament busbar carbon.

Abstract: ROVs have a variety of applications, including mapping, exploration and monitoring of the ocean. They are capable of collecting high-quality images
and measuring physical-chemical parameters of water, which makes them ideal for monitoring marine life andobserving the impact of human activities on the environment, as well as helping to identify and study species of fish, including their abundance and distribution. These records are used to map and understand subtle changes in the ecosystem of a river or lake. Their agility and ease allow these robots to perform search and monitoring tasks safely and economically, without putting human life at risk. The present work aims to build an ROV in an accessible way, using materials and electronic components easily available on the market, such as those used in drones.

Abstract: Industry 4.0 represents a technological revolution in manufacturing operations, focusing on digitization and automation to optimize production. This study proposes a methodology for implementing monitoring and data collection systems in digital factories, emphasizing the use of the OPC UA protocol on the Siemens S7 1200 PLC. Through the installation of sensors and artificial intelligence algorithms, the aim is to gain real-time insights into processes, enhancing operational efficiency.
In the Instrumentation Laboratory at PUC Goiás, the research demonstrated the effectiveness of integrating diverse systems via OPC UA, highlighting the configurational capability of the OPC UA server on the Siemens S7 1200 PLC. Using the Prosys OPC UA Monitor as a supervisory system, the study validated the possibility of integrating systems from different suppliers, providing robust, standardized, secure, and scalable solutions.
However, the digitization journey presents challenges, including infrastructure investments and concerns about data security. In conclusion, this work not only successfully achieved its initial objectives but also underscored the ongoing importance of technological advancements for efficient and secure system integration in the era of Industry 4.0.

Abstract: Considering the relevance of early analysis of economic options, this work sought to evaluate the financial strategy, from the cus-tomer's perspective, of the migration of a consumer with demand of less than 500 [kW], from the captive market (Regulated Con-tracting Environment - ACR) to the free market (Free Contract-ing Environment - ACL), in accordance with the new energy trading rules in Brazil that will come into force in 2024. Compari-sons will be made between the costs of purchasing energy in both situations, involving the use of incentivized tariffs, coming from renewable sources. With this in mind and taking into account that the consumer unit will be represented by the retail agent before the Electricity Trading Chamber, a monthly saving of approximately 21.84% was found.
