Abstract:According to the production practice and the production process characteristics of Pulping and Papermaking, the emission factors of carbon dioxide (CO2) were deduced to be 0.229, 1.304, 1.5, 3.69t/t respectively for the mainstream of pulping technology, the main-stream of papermaking technology, the pulp paper substitution of coal waste residue, the methane substitution of coal. Based on the above figures and other related materials, the paper analyzed the effects of different parts of paper-making machine on the CO2 emission factors, and simulated the corresponding total CO2 emissions derived from different production scales. It indicated that among the total CO2 emission in paper manufacturing enterprise, the papermaking system and the waste disposal system are responsible for the dominant 54.23% and 33.86% respectively; the power consumption of papermaking system and pulping system contributed 75.6% and 90.22% respectively to the total CO2 emission; while in waste disposal system, the indiscriminate disposal of pulp-and-paper waste residue and the arbitrarily discharged methane contributed 46.06% and 47.59% respectively to the total CO2 emission in this stage.
