Captação de água pluvial para reuso em uma fábrica na cidade de Goiana-PE This study aims to implement a rainwater harvesting system via a roof in a factory located in the municipality of Goiana/PE, evaluating its environmental and economic impacts. Specific objectives include: conceptualizing rainwater reuse and its relevance to sustainability; identifying the construction processes necessary for harvesting; and installing a suitable storage reservoir. The methodology adopted is applied, with a qualitative and quantitative approach, based on a literature review and case study. Technical, environmental, and socioeconomic aspects related to the implementation of the harvesting system were analyzed. The procedure included evaluating the building's roof structure, sizing gutters and downpipes, installing a reservoir for rainwater storage, and proposing a treatment method for non-potable uses. An estimate of the reduction in water consumption from the public supply system and the financial savings resulting from reuse was also carried out. The results indicate that the implementation of the rainwater harvesting system is technically feasible and environmentally beneficial. Significant potential for reducing the demand for potable water in activities such as irrigation was observed, contributing to a decrease in the overload on the public water supply system. Furthermore, it was found that rainwater harvesting helps reduce surface runoff, minimizing the risk of flooding and impacts on urban drainage systems. It is concluded that the implementation of a rainwater harvesting system at the factory in Goiana/PE represents a sustainable and efficient alternative for water resource management, promoting environmental, economic, and social benefits. The adoption of this practice contributes to the preservation of natural resources, reduction of operational costs, and strengthening of actions aimed at sustainability in the urban and industrial context.

Ionizador solar alternativo para tratamento de água de piscina The solar ionizer represents an alternative and sustainable approach to swimming pool water treatment, as it seeks to reduce dependence on chlorine while minimizing environmental and health-related impacts. The objective of this study was to develop and evaluate the effectiveness of an alternative solar ionizer prototype for swimming pool water treatment in the city of Recife, Pernambuco, Brazil. This research is aligned with the United Nations Sustainable Development Goals (SDGs) of the 2030 Agenda for Sustainable Development, proposing a low environmental impact technology capable of reducing the formation of harmful disinfection by-products such as Trihalomethanes (THMs), which may pose risks to human health. The study was based on a comprehensive literature review of water disinfection systems, including the analysis of existing models and patents of solar ionizers in order to support the development of the proposed system. A functional prototype was then constructed in Recife using copper bars to release antimicrobial ions, powered by a 12-volt solar panel. The validation process involved installing the prototype in an experimental swimming pool located on Rua Guapé, nº 187, in the Zumbi neighborhood of Recife. During this stage, physicochemical and microbiological parameters were monitored and compared with the results obtained through conventional chlorination methods, in accordance with the ABNT NBR 10818:2016. The results demonstrated the effectiveness of the solar ionizer in maintaining water quality, a significant reduction in chlorine consumption, and a favorable cost-benefit relationship. These findings indicate that the proposed technology represents an environmentally sustainable and economically viable alternative for swimming pool water management.

O papel estratégico do setor de compras na cadeia de suprimentos da construção civil Recife Organizations in the construction sector, in the face of an increasingly competitive and complex environment, need to continuously improve their procurement processes for materials and services in order to ensure technical quality, compliance with deadlines, and financial sustainability. In this context, the purchasing department has ceased to be understood merely as an operational function and has come to assume a strategic role in supply chain management, directly influencing the productive and economic performance of projects.The present study analyzes the relationship between the efficiency of the purchasing department in the construction industry and the final quality of the products delivered, as well as the impacts of its practices on schedule compliance and organizational profitability, from a systemic perspective of logistics and supply processes, from the viewpoint of professionals working in the field. To this end, an exploratory, descriptive, and applied research study was conducted, using a qualitative-quantitative approach, based on the application of a structured questionnaire via Google Forms to employees of the purchasing department of a company operating in the construction sector.The data analysis made it possible to identify the main bottlenecks and control limitations in the purchasing process, such as communication failures between departments, lack of standardized procedures, weaknesses in deadline monitoring, and the absence of integrated management systems. Furthermore, the relevance of the purchasing professional in decision-making processes that ensure technical compliance and the performance of materials used in construction projects was highlighted, as well as the importance of properly defining delivery deadlines to maintain the continuity of the production flow and compliance with the physical schedule.The results also demonstrated that inadequate purchasing practices tend to increase project costs, whereas structured processes, strategic planning, and integration between purchasing, logistics, and planning contribute to greater operational and financial efficiency. It is concluded that the structuring of purchasing systems and their articulation with on-site logistics are determining factors for the quality of projects, the reduction of waste and rework, and the economic sustainability of organizations in the sector.

Uso de Wetland construída para tratamento das águas do riacho cavouco The scarcity of basic sanitation infrastructure in urban centers results in severe envi ronmental degradation and public health problems. In Recife, a significant portion of domestic sewage is discharged untreated into water bodies, as occurs in the Cavouco Stream, a tributary of the Capibaribe River. Given the high cost of implementation (CA PEX) and operation (OPEX) of conventional systems, this work is based on Water Sensitive Urban Design (WSUD) to propose and evaluate the technical feasibility of a Vertical Subsurface Flow (VSF) Constructed Wetland phytoremediation system in Cai ara Park. Based on primary data, an influent flow of 69.120 m³/day and Biochemical Oxygen Demand (BOD) concentrations incompatible with Class II waters were found. Theoretical sizing indicated the need for 89.096 m² of filter bed for the complete trea tment of the flow. However, the topographic survey revealed a usable area of 18,000 m², making the integral model unfeasible and justifying the adoption of a bypass sys tem capable of treating 14% of the flow (9.775 m³/day). When comparing this prelimi nary design with the actual pilot project executed on site, it was observed that the engineering adopted an even more conservative hydraulic load (432 m³/day) to gua rantee purification efficiency in the face of the high pollutant load. It is concluded that the system is topographically and hydraulically viable, harmonizing sanitation infras tructure, landscaping, and low operational cost.
