Application of Cleaner Production (CP) to improve waste management in paper pre-printing process - a case study in a Curitiba packaging company

Abstract

The world demand for water has increased for different reasons, such as changes in the consumption patterns of the people, and even the increase in market production. In addition, the water scarcity experienced by many countries, including Brazil, highlights the need for conscientious use and preservation of the water resource, whether by people or companies. Thus, this paper aimed to propose improvements for the lack of effluent treatment generated by the paper roll prepress process in a large packaging company Curitiba. Then, driven by the Cleaner Production (CP) methodology, take a few steps to reach the result: carry out the action plan to execute the selected improvement opportunity. Thus, after implementing the action plan, it is expected to reuse 95% of the water from the treated effluent and reduce the plant's water consumption by 2.45% per month. Thus, the aim is to achieve level 2 of the cleaner production methodology or reduce the environmental impact caused by the effluent from the paper roll prepress process.
