Item GESTÃO TERMOECOLÓGICA DE USINAS TERMOELÉTRICAS COM MOTORES DE COMBUSTÃO INTERNA: MODELO BASEADO EM ASPECTOS TÉCNICOS, ECONÔMICOS E AMBIENTAIS(Universidade Federal de Santa Catarina, 2017) SILVA, Wagner Ferreira; CAMPOS, Lucila Maria de SouzaAlthough there is a global trend toward renewable energy use, in thermoelectric plants, the main energy source remains fossil fuels. These plants, while generating the required electrical power for consumption, are significant sources of environmental pollution. This thesis develops a proposal for the thermoecological management of thermoelectric plants, jointly evaluating the thermal and environmental efficiency of internal combustion engines powered by fossil fuels, specifically fuel oil and natural gas. Different mathematical models were created and used in the development of procedures integrating technical (efficiencies), economic (fuel consumption and cost), and environmental (emission index, ecological function, and eco-efficiency) aspects. For the first time, the concept of entransy is applied to evaluate engine efficiency and to enhance the ecological function initially developed by Angulo-Brown. The concept of eco-efficiency was employed in the multi-objective optimization of load dispatch, allowing managers to evaluate different simulations in pursuit of higher thermoecological efficiency. Practical evaluation was carried out through the application of these procedures in a specific software for the type of thermoelectric plants analyzed. The main results include theoretical advances in thermoecological management and the creation of a practical tool for data analysis and decision-making. The effectiveness of the proposed procedures was demonstrated in real cases with different generation and fuel type scenarios.Item Eco-efficiency in industry and PML plastic, reducing waste stretch film in production(INSTITUTO DE TECNOLOGIA, 2015) VASCONCELOS, Agna de Souza; COSTA, Elis Patrícia Silva; MONTEIRO, Mayna Carolina Alves; MAGALHÃES, Edilson MarquesThis study explores the application of Cleaner Production (CP) tools combined with eco-efficiency in the plastics industry, focusing on waste reduction in stretch film production. A quantitative case study identified inefficiencies in raw material handling and logistics, leading to high costs and environmental impacts. The proposed solution includes installing fixed pipelines and preventive maintenance to reduce virgin material consumption and enhance operational efficiency. The results show that adopting these practices can yield significant cost savings and promote sustainability.
