Identificação de oportunidades de circularidade em uma máquina de papel kraft

Abstract

Circular economy arises from the need to reduce the consumption of natural resources, emissions and extend the life of products and materials. The paper industry is recognized for being highly demanding of resources such as water, electricity, raw materials, inputs and emissions generator. In this sense, the present work consisted in identifying circularity opportunities, based on the circular economy, in a kraft paper machine, in a pulp and paper industry in the state of santa catarina. For this, a case study and an action research were carried out, which allowed the reduction of wing glue consumption, optimization of the use of tubes and opportunities for water recirculation in the kraft paper machine. The opportunities identified were implemented in the company, generating monetary savings for such, and these results showed that through Circular Economy, there are potential environmental improvements in the processes and cost reduction by optimizing the use of materials.
