The objective of this study was to investigate the challenges and technical solutions adopted in this retrofit process, contributing to the advancement of knowledge about interventions in historic structures. The research involved direct data collection on site, application of non- destructive testing to assess concrete strength, computational modeling for structural simulation, and comparative analysis with Brazilian standards. Sections 1 and 2 were reinforced with embedded slabs, chamfered casing, and grouting of exposed reinforcement, ensuring structural stability and safety. Section 3, due to its compromised condition, was demolished and rebuilt with rigorous planning to preserve the integrity of the remaining structure and the safety of workers. Continuous monitoring, through technical inspections and data validation, ensured regulatory compliance and economic viability. Daily monitoring of the demolition was essential for identifying critical points and sizing reinforcements, optimizing interventions. The study contributes to civil engineering by documenting a practical case study of structural rehabilitation in a historic building, demonstrating the importance of integrating technical analysis, on-site monitoring, and simulation technologies. The Moinho project reaffirms that the preservation and adaptation of old buildings, when conducted based on sound technical criteria, can result in projects of high architectural, functional, and economic value, reconciling historical memory and construction innovation.

This study analyzed the evolution of sanitary sewer services in Recife between 2016 and 2025, considering the targets established in the Municipal Basic Sanitation Plan (MBSP) and comparing the city's performance with that of other state capitals in Northeastern Brazil. This descriptive-analytical study adopted a quantitative approach based on historical secondary data obtained from the National Sanitation Information System (SNIS) and the National Basic Sanitation Information System (SINISA). Historical data on sewage collection and treatment coverage were examined, and Recife's performance was compared with that of Salvador and Fortaleza. The results indicated stagnation in sewage collection collection coverage, which increased only marginally from 39.95% in 2016 to 40.28% in 2025, remaining well below the target of 90% established for 2033. Conversely, the sewage treatment rate remained close to 100%. It is concluded that Recife has made progress in wastewater treatment infrastructure but still faces significant challenges in expanding sewage collection coverage.

Solid Waste management is a widely discussed topic throughout the world, either because of its social, economic or environmental importance. In this context, the objective of this work was to map the international scientific analysis on Solid Waste without resorting temporarily between the years 1968 and 2025, analyzing the records that present the term selected for a search, based on literature review on a question in question. In this sense, a research with information participation for other researchers of the subject, since it is able to develop a set of knowledge, through theanalysis and critical analysis of a scientific production. To do so, use as a methodological procedure a bibliometric survey; Using as a tool, the SCOPUS database and from it were 662 publication records in 151 different journals. The points were analyzed for: i) publications; (ii) countries; (iii) periodicals; iv) citations; v) keywords; vi) authors; (vii) types of publication; viii) membership and ix) subject area . The main findings pointed to a position of greatness in Latin American countries, especially Brazil; was also a research in the last twenty years, being in 2022 the year with more publications; a wide variety of objects of study, which are an integral part of a strategy of economy, society and environment.

The research adopted a mixed-methods approach, using bibliographic and documentary research, analysis of official data from the Integrated Highway Operations System (SIOR/DNIT), and an on-site questionnaire with semi-structured interviews conducted with 14 of the 19 merchants identified at the location. The results showed a predominance of rear-end collisions, accounting for 68% of the recorded crashes, mainly associated with sudden reductions in vehicle speed. The study aimed to identify the reasons for the irregular occupations in order to propose solutions that could be implemented in the short and medium term, with the aim of ensuring compliance with specific legislation while respecting the social rights established by the Brazilian Constitution. The interviews revealed that the merchants' continued presence within the right-of-way stems from the lack of formal employment opportunities. The study concludes that irregular occupation contributes to increased exposure to road safety risks, highlighting the need for integrated actions involving engineering, land-use planning, and socioeconomic inclusion.
