The work is focused on approaches to waste paper processing. Waste management is an important component of managerial decision-making in businesses and in the public administration sector. Environmental legislation creates continual pressure on finding new solutions that are both economically advantageous and environmentally friendly. In the context of the EU efforts to restrict the volume of emitted carbon dioxide, it is necessary to look for new solutions to fulfill the established requirements. The article focuses on issues of energy generation from municipal waste paper, a procedure that is also fully applicable in businesses. The work describes waste management legislation and evaluates the results of state regulation. After the analysis, which is made on the basis of evidence that recycling of waste paper does not always represent the best solution in terms of sustainability, a possibility for its energy use is proposed. Two models for the use of waste paper are forwarded – for the production of thermal energy and for the combined production of thermal and electrical energy. The models are developed separately for the production of thermal energy from waste paper and for the combined production of heat and electricity as proposed in the second model. The theoretical background and proposed models are verified for concrete calculation on the basis of waste management in the city of Děčín. Software based on Petri nets was used for model construction; this allows the inclusion of the most relevant material and energy flows associated with energy production from waste paper, guaranteeing the high accuracy of the calculated results. The advantage of the model proposed in this manner is the simple and precise quantification of the environmental and economic impacts of the proposed measures; these are the main reasons for its good utilization as a tool for supporting managerial decision-making.
