Dissolving pulp production is mostly reliant on wood, which drastically depletes forest resources. To prevent the over-exploitation, the efforts were required by considering waste materials utilization. Therefore, a comprehensive assessment to account for environmental impacts was needed. The purpose of this research was to determine the environmental impact of empty fruit bunches (EFB) utilization from oil palms as a promising raw material substitute for wood in the production of dissolving pulp and furfural as co-product. The consequential life cycle assessment (cLCA) was performed by following the methodology in ISO 14040. Inventory for the input–output materials and energies for the proposed integrated dissolving pulp and furfural co-production process was evaluated based on laboratory-scale experiments. Meanwhile, the field survey as a reference for the existing practice in the conventional dissolving pulp industry was conducted. The SimaPro v8.0.5® software was used for the LCA calculation with the Centrum voor Milieuwetenschappen Leiden (CML) environmental impact assessment method. Several environmental impact categories, such as acidification, global warming, eutrophication, and human toxicity potential, were quantified. This study examined three proposed scenarios for dissolving pulp and furfural co-production compared with the conventional dissolving pulp production. In the Scenario 1, 50% of the wood consumption was replaced by EFB and applied to acid prehydrolysis/soda cooking followed by ECF bleaching, with an additional process to co-produce furfural. In the Scenario 2, 100% of wood consumption was replaced by EFB, with the same cooking and bleaching parameters as those in Scenario 1. In the Scenario 3, 100% of wood consumption was replaced by EFB, and the acid was replaced by water in the prehydrolysis process to improve the total environmental performance with the same conditions as the previous scenarios. The Scenario 3 was the most promising scenario and had the lowest environmental impact. This research was conducted to propose EFB, which is environmentally sustainable and economically profitable, as a wood substitute in the co-production of dissolving pulp and furfural. The scenarios were proposed and compared with the existing practices. Based on the cLCA approach, this study recommended the EFB as a promising raw material and referred to Scenario 3 for the environmentally friendly system production.

基于油棕空果串 (EFB) 的综合溶解浆和糠醛生产的开发:一种相应的 LCA 方法

溶解浆生产主要依赖木材,这极大地消耗了森林资源。为了防止过度开发,需要考虑废物利用。因此,需要对环境影响进行综合评估。本研究的目的是确定利用油棕的空果串 (EFB) 作为木材的有前途的原材料替代品生产溶解浆和糠醛作为副产品的环境影响。后续生命周期评估 (cLCA) 是按照 ISO 14040 中的方法进行的。根据实验室规模的实验评估了拟议的集成溶解浆和糠醛联合生产工艺的输入-输出材料和能源的库存。同时,进行了实地调查,作为传统溶解浆行业现有做法的参考。SimaPro v8.0.5® 软件用于通过 Centrum voor Milieuwetenschappen Leiden (CML) 环境影响评估方法进行 LCA 计算。量化了几个环境影响类别,例如酸化、全球变暖、富营养化和人类潜在毒性。本研究检验了溶解纸浆和糠醛联合生产与传统溶解纸浆生产相比的三种拟议方案。在场景 1 中,50% 的木材消耗被 EFB 取代,并应用于酸预水解/苏打蒸煮,然后是 ECF 漂白,以及联合生产糠醛的额外过程。在场景 2 中,100% 的木材消耗被 EFB 取代,与场景1相同的蒸煮和漂白参数。 在场景3中,100%的木材消耗被EFB代替,预水解过程中的酸被水代替,以在相同条件下改善总体环境绩效之前的场景。情景 3 是最有希望的情景,对环境的影响最小。进行这项研究的目的是提出 EFB,它具有环境可持续性和经济利润,可作为联合生产溶解纸浆和糠醛的木材替代品。提出了这些方案并与现有做法进行了比较。本研究基于 cLCA 方法,推荐 EFB 作为有前景的原材料,并参考情景 3 进行环保系统生产。在场景3中,100%的木材消耗被EFB替代,预水解过程中的酸被水替代,以在与之前场景相同的条件下提高总体环境绩效。情景 3 是最有希望的情景,对环境的影响最小。进行这项研究的目的是提出 EFB,它具有环境可持续性和经济利润,可作为联合生产溶解纸浆和糠醛的木材替代品。提出了这些方案并与现有做法进行了比较。本研究基于 cLCA 方法,推荐 EFB 作为有前景的原材料,并参考情景 3 进行环保系统生产。在场景3中,100%的木材消耗被EFB替代,预水解过程中的酸被水替代,以在与之前场景相同的条件下提高总体环境绩效。情景 3 是最有希望的情景,对环境的影响最小。进行这项研究的目的是提出 EFB,它具有环境可持续性和经济利润,可作为联合生产溶解纸浆和糠醛的木材替代品。提出了这些方案并与现有做法进行了比较。本研究基于 cLCA 方法,推荐 EFB 作为有前景的原材料,并参考情景 3 进行环保系统生产。并且在预水解过程中用水代替酸,以在与之前情景相同的条件下改善总体环境性能。情景 3 是最有希望的情景,对环境的影响最小。进行这项研究的目的是提出 EFB,它具有环境可持续性和经济利润,可作为联合生产溶解纸浆和糠醛的木材替代品。提出了这些方案并与现有做法进行了比较。本研究基于 cLCA 方法,推荐 EFB 作为有前景的原材料,并参考情景 3 进行环保系统生产。并且在预水解过程中用水代替酸,以在与之前情景相同的条件下改善总体环境性能。情景 3 是最有希望的情景,对环境的影响最小。进行这项研究的目的是提出 EFB,它具有环境可持续性和经济利润,可作为联合生产溶解纸浆和糠醛的木材替代品。提出了这些方案并与现有做法进行了比较。本研究基于 cLCA 方法,推荐 EFB 作为有前景的原材料,并参考情景 3 进行环保系统生产。进行这项研究的目的是提出 EFB,它具有环境可持续性和经济利润,可作为联合生产溶解纸浆和糠醛的木材替代品。提出了这些方案并与现有做法进行了比较。本研究基于 cLCA 方法,推荐 EFB 作为有前景的原材料,并参考情景 3 进行环保系统生产。进行这项研究的目的是提出 EFB,它具有环境可持续性和经济利润,可作为联合生产溶解纸浆和糠醛的木材替代品。提出了这些方案并与现有做法进行了比较。本研究基于 cLCA 方法,推荐 EFB 作为有前景的原材料,并参考情景 3 进行环保系统生产。
