However, the variability in the chemical and thermal characteristics of the waste materials poses significant challenges to defining an adequate mixture composition, which may compromise process stability and product quality. In this context, this work develops and applies mathematical programming models to optimize the composition of waste mixtures in the co-processing sector of a cement plant, considering operational, chemical, and material availability constraints. The approach is based on a case study involving process mapping and analysis, formulation of the optimization model, computational implementation in a spreadsheet environment, and monitoring of results through Statistical Process Control tools. The results indicate a reduction in the variability of the main mixture characteristics, with improved compliance with the established specification limits, particularly for moisture content and lower heating value. Control charts and process capability analyses demonstrate increased stability, predictability, and control of the process after the implementation of the proposed solution, highlighting the potential of integrating mathematical modeling and statistical tools to support decision-making in complex industrial environments.

To this end, a quantitative study was conducted based on a sample of 46 events from a company specialising in open bar cocktail services, located in the city of João Pessoa, between December 2024 and September 2025. The data were analysed using descriptive statistics and analysis of variance (ANOVA), supported by SPSS software, in order to identify significant differences among the groups examined. The results indicate that beverage consumption varies significantly according to the type of event, constituting the primary cost driver of the service. In contrast, fruit consumption exhibited low variability and did not demonstrate a relevant influence on total costs, regardless of event type. These findings reveal the existence of distinct consumption patterns, enabling the open bar cost structure to be understood through two dimensions: a behavioural dimension, associated with beverages, and an operational dimension, related to complementary inputs. As a practical implication, the study contributes to the improvement of service planning and management by supporting the development of more robust strategies aligned with the specific characteristics of each type of event.

This study aims to evaluate the impacts of the lack of ergonomic and organizational adaptation in the home office regime on the physical and mental health of professionals, identifying how the improvisation of the workstation affects employee well-being. The methodology is characterized as a descriptive research of a quantitative nature, conducted through a data survey with 62 professionals working in remote or hybrid models. The results revealed a critical lack of infrastructure: most respondents use improvised furniture, such as chairs without lumbar support and inadequate desks, which correlates directly with the high rates of reported lower back pain (68.94%) and cervical pain (75.85%). Within the organizational scope, it was identified that hyperconnectivity and attention fragmentation caused by digital notifications are vectors of exhaustion. It was observed that the “flexibility trap” and the lack of boundaries between personal and professional life aggravate stress, while the lack of instruction provided by companies (87.9%) highlights corporate negligence regarding occupational health in telework. It is concluded that the sustainability of remote work requires organizations to transcend technological support and implement improvements in mental workload management and the physical ergonomics of home-based workstations, aiming to mitigate employee illness and ensure long-term productive efficiency.
