摘要： Digitalization, changes in social behavior, and sustainability are some of the global megatrends shaping industry evolution. The pulp and paper (P&P) industry, historically based on renewable resources, is facing the same challenges. Even though the environmental life cycle assessment (LCA) methodology has been utilized for more than 30 years now, it is still challenging to apply its concepts to reach a consensus. To address this issue, the Sustainable and Alternative Fibers Initiative (SAFI) has been working to develop a robust methodology to evaluate a range of P&P products from conventional and emergent alternative fibers. The methodology developed included the inclusion of the potential soil organic carbon (SOC) sequestration by each cultivar based on the carbon inputs from below-ground biomass (coarse roots and rhizodeposition) that can increase carbon levels in the soil. Moreover, detailed process simulation based on industrial conditions is used to perform all mass and energy balances, allowing rigorous estimates of the life cycle inventory and total carbon dioxide emissions. As a case study, two types of biomass (eucualyptus and wheat straw) were analyzed for their environmental LCA. Additionally, bleached eucalyptus kraft (BEK) produced in Brazil and wheat straw alkaline-peroxide mechanical pulp (APMP) for possible applications in commercial tissue were also studied. The overall carbon footprint results are dependent on whether or not SOC sequestration is included. Further, the results for carbon emissions are significantly altered when biogenic emissions are considered in addition to anthropogenic emissions. The presentation will discuss the results.
