Carbon Monoxide Monitoring System and Green Credit Calculation
Carbon Monoxide (CO), a critical industrial pollutant, requires strict monitoring due to its health risks and contribution to the greenhouse effect. This project develops a low-cost IoT system (MQ-7 sensor + ESP32) to monitor CO emissions in real time. Its main differentiator is the integrated dashboard that converts the measurements into green credit values (carbon credits). The goal is to provide an accessible tool for industries to efficiently and strategically promote and manage the offsetting of their carbon footprint.

Traffic congestion in large urban centers is caused by road saturation and the inefficiency of public transportation. To mitigate this problem, the project proposes the implementation of smart traffic lights equipped with sensors that identify the number, type, and speed of vehicles. Based on this data, an algorithm adjusts the signal timings, prioritizing public transport and enhancing safety. The initiative aims to optimize traffic flow, reduce travel time, improve urban mobility, and decrease pollutant emissions. Pedestrians and cyclists would also benefit from traffic lights adapted to their needs.

INCREASE IN PRODUCTION LINE DEMAND: DECISION-MAKING FOR ADDING WORKFORCE – PROJECT TITLE
With the growing development of the automotive market, auto parts industries have identified the need to adapt in order to maintain competitiveness. The industry studied in this article also faced this scenario: at the beginning of the year, one of its largest-volume clients signaled an increase in demand starting in the second half of 2025. In response to this request, the company needs to make a decision: either adapt the production line by adding direct labor (MOD) and balancing activities, or study the layout and line balancing to maintain the existing four operators while increasing the number of pieces produced per hour. The main objective of this project is to determine which of the two scenarios is most suitable, taking into account operator safety, product quality, and client demand. It is important to highlight the theoretical number of operators, a calculation that will show how many operators are needed based on the activities and their cycle times. Within this study, the Sustainable Development Goal (SDG) is considered, particularly Goal 9, which states: “Build resilient infrastructure, promote inclusive and sustainable industrialization, and foster innovation.”
This project started from a simple question: would it be possible to illuminate small spaces using only wind and some repurposed materials? We noticed that many places—such as outdoor areas of houses, small corridors, bus stops, or community spaces—often remain in the dark due to lack of infrastructure or high energy costs. This motivated the search for a more accessible alternative. We began by researching vertical-axis turbine models and found that they work well in locations where the wind is not very strong and changes direction frequently. From there, we sought a solution that would be easy to assemble, inexpensive, and reproducible by anyone using materials that would normally be discarded.

This project originated from a simple question: would it be possible to illuminate small spaces using only wind and some repurposed materials? We noticed that many places—such as outdoor areas of houses, small corridors, bus stops, or community spaces—often remain in the dark due to a lack of infrastructure or the high cost of electricity. This motivated us to seek a more accessible alternative. We began by researching vertical-axis turbine models and found that they work well in locations where the wind is not very strong and frequently changes direction. From there, we aimed to develop a solution that would be easy to assemble, inexpensive, and reproducible by anyone using materials that would normally be discarded.

Industrial Fluid Dynamics: Emulsions in the Petrochemical Industry
The extraction of crude oil in the petrochemical industry frequently results in the formation of stable water–oil emulsions, which hinder transportation and refining processes and increase operational costs. These emulsions are generally stabilized by natural compounds present in petroleum, such as asphaltenes, and are further aggravated by conditions such as process turbulence during extraction and the presence of fine particles. Efficient separation of these phases, known as demulsification, is essential to ensure oil quality and to meet industry standards. Among the methods used to promote this separation, the addition of certain chemical agents—such as calcium chloride (CaCl₂)—stands out, as it has proven effective in destabilizing emulsions by reducing interfacial tension and promoting the coalescence of water droplets, thereby facilitating their removal from crude oil.
