Avaliação do desempenho do sistema de gestão ambiental na Açucareira da Maragra

Abstract

The environmental performance of an industrial process is the result of the environmental management of its environmental processes, aspects and impacts. The most significant impacts must be identified in order to define the best way to control and minimize those impacts. On the other hand, for environmental performance to be measured and monitored, performance indicators must be defined and aligned with the objectives, goals and strategies of a given industry. The present work had as general objective to evaluate the performance of the environmental management system (SGA) in the Maragra sugar plantation, verifying its adequacy/integration in accordance with the strategies, goals, objectives of the company. The performance evaluation methodology used was comparative to the indicators and deductive. Operational performance data (water and energy consumption, amount of waste sent to landfill and sugar produced) for a period of 9 weeks and the environmental condition (pH, COD and temperature increase) for a period of 12 weeks. were collected through surveys. Additionally, in the same period (12 weeks), the training center management performance data such as the number of workers trained under the EMS and not trained as well as the number of planned and carried out audits. The data obtained from these indicators were compared, respectively, to the regulation of effluent emission standards for the environmental condition indicators, values ​​estimated by the world bank on energy consumption and values ​​established by ARA-Sul for water consumption and quantity of waste sent to landfill. The results obtained revealed that the environmental condition indicator showed changes in the COD values, of 265 mg/l (in the first week) and 498 mg/l (in the second week), values ​​that are outside the limits pre-established by the so-called regulation. on the Environmental Quality and Effluent Emission Standards for the Sugar Industry (Decree nº 18/2004). The results of the operational performance indicators indicated that the value of energy consumption of 2335.13 MJ/Kg was higher than the one pre-established by the International Finance Corporation. Despite these changes observed in some indicators of environmental performance, it was concluded that the system of management implemented in Maragra is efficient. (TRADUÇAO NOSSA)
