【目的】

我国纸浆行业是温室气体排放的重要贡献者，其木材原料获取过程导致的森林碳汇损失尤为突出。国内木浆产量和消耗量持续攀升，进一步加剧了碳排放与木材资源压力，对实现行业减排目标构成严峻挑战。为应对这一挑战，缓解森林碳储量损失并降低行业碳排放水平，提出芦竹原料替代木浆原料生产纸浆，并评估其减排潜力及森林碳汇保护效益。

【方法】

采用生命周期评价法，量化分析木浆与芦竹浆产业链的温室气体排放，系统评估原料替代策略（芦竹替代木材）在纸浆行业减排中的潜在贡献。

【结果】

芦竹替代木材生产纸浆可显著降低温室气体排放，不同纸浆类型（BCP、UBCP、CMP）的单位产量（1 Adt）减排量为0.056～0.214 tCO₂e，相当于减少3.42%～14.76%的温室气体排放，其中原料收集和运输阶段是关键减排环节。同时，使用1 Adt芦竹浆可减少约4.732 m³的木材采伐，保留约4.844 tCO₂e的森林碳储量。基于2025年我国46家制浆工厂65条生产线的木浆产能规划情景分析表明，漂白化学浆（BCP）的减排潜力最大，山东、湖北和广西是减排的关键区域。在2060碳中和目标下，全面实施芦竹原料替代策略，预估每年可保留39.26～157.05 TgCO₂e的森林碳储量，并显著降低我国对进口木材的依赖。

【结论】

芦竹原料替代木材原料生产纸浆，具有显著的温室气体减排与森林碳汇保护的协同效益，不仅能降低我国对进口木材的依赖，还能为纸浆行业落实国家2060碳中和目标提供科学可行的技术支撑。

【Objective】

China's pulp industry is a significant contributor to greenhouse gas emissions, and the loss of forest carbon sinks due to the process of obtaining wood raw materials is particularly significant. Domestic wood pulp production and consumption continue to rise, further intensifying carbon emissions and pressure on timber resources, posing a serious challenge to achieving industry emission reduction targets. To address this challenge, mitigate the loss of forest carbon stocks and reduce carbon emissions from the industry, this study proposes the replacement of wood pulp raw materials with giant reed raw materials in the production of pulp and evaluates the potential for emission reduction and avoidance of the loss of forest carbon stocks.

【Method】

This study adopts the Life Cycle Assessment (LCA) method to quantitatively analyze the greenhouse gas (GHG) emissions of the wood pulp and giant reed pulp industry chain, and systematically assesses the potential contribution of the raw material substitution strategy (giant reed instead of wood) in the reduction of emissions in the pulp industry.

【Result】

The replacement of wood by giant reed in the production of pulp significantly reduces greenhouse gas emissions. The life cycle assessment shows that the emission reduction per unit of production (1 Adt) for different pulp type (BCP, UBCP, CMP) is about 0.056-0.214 tCO₂e, which is equivalent to a reduction of GHG emissions by 3.42%-14.76%, with the raw material collection and transportation stages being the key emission reduction links. At the same time, the use of 1 ton of ruderalis pulp reduces timber harvesting by about 4.732 m³ and retains about 4.844 tCO₂e of forest carbon stocks. The analysis of wood pulp capacity planning scenarios based on 65 production lines in 46 pulp mills in China in 2025 shows that bleached chemical pulp (BCP) has the greatest potential for emission reductions, and that Shandong, Hubei, and Guangxi are key regions for emission reductions. Under the 2060 carbon neutrality goal, the full implementation of the giant reed feedstock substitution strategy is predicted to retain about 39.26-157.05 TgCO₂e of forest carbon stocks per year and significantly reduce dependence on imported wood.

【Conclusion】

Substitution of giant reed raw materials for wood raw materials for pulp production has significant synergistic benefits of greenhouse gas emission reduction and forest carbon sink protection, which not only reduces dependence on imported wood, but also provides scientific and feasible technological support for the pulp industry to implement the national 2060 carbon neutrality goal, while significantly reducing dependence on imported wood.
