Evaluation of environmental impacts is an important issue nowadays, especially in industry. There is an increase concern by modern society in relation to the industry environmental and social impacts, which reflect on the product market. People prefer environmentally sound products. The pulp and paper sector is often criticized for its environmental performance. The intensive use of wood, the large demand for water use and generation of effluents and solid wastes in addition to the air emissions makes this industry a potential polluter. Life cycle analysis (LCA) is a powerful tool to evaluate the relation among production systems, products or activities and the environment. It identifies and quantifies system fluxes input (energy, material) and output (products, emissions) in order to evaluate the impacts of the utilization/release in the environment. The results of the LCA help the implementation of opportunities to enhance environmental performance. The first chapter of this thesis presents an evaluation of the current environmental aspects of the pulp and paper industry. The main environmental management systems used by industry is discussed in Chapter 2. Life cycle analysis in the production of kraft pulp is presented in Chapter 3.
