Life cycle energy consumption analysis and green manufacture evolution for papermaking industry in China

Abstract

Papermaking is a high energy-consuming industry. The growth of paper demand will further intensify the need of energy and the stress of GHG emissions. Papermaking involves complex processing routes, energy is required for collecting raw materials, producing chemicals, pulp and papermaking. Previous investigations of energy consumption in papermaking industry has focus primarily on the analysis of one single product or one single pathway, lacked in a comprehensive and systematic comparison about various products and pathways. Herein, the results of life cycle energy consumption of major paper products in China using an extensive system boundary are presented. When 1 ton of paper is produced in China in 2015, the maximum energy consumption is 38.17 GJ for tissue paper, with a minimum energy consumption of 15.90 GJ for corrugating medium. This study also predicts energy-related GHG emissions and mitigation target in papermaking industry in China by 2050. Although the energy consumption assumed to distribute to papermaking industry can meet its development requirement, the GHG emissions will exceed mitigation target by about 101 Mt CO2 eq in 2050 under current policy. The target can be achieved by changing energy structure and promoting low-carbon technology.
