Abstract

The future of sustainable chemicals lies in the adoption of renewable sources such as biomass conversion. One unique biomass that can be utilized is water hyacinth. Apart from being able to overcome river pollution, its valorization can produce bio-oil. In this study, the environmental impacts of water hyacinth pyrolysis were assessed. It employed the life cycle assessment (LCA) approach with a cradle-to-gate system boundary and a functional unit of 50 kg of bio-oil. The pyrolysis of 250 kg of pretreated water hyacinth at 400°C demonstrated a yield of 19.45% ± 1.02% for bio-oil. Following the results, the pyrolysis process predominantly contributes to 66.2%–99.7% of environmental impacts due to the high liquid petroleum gas (LPG) requirement. The sensitivity results exhibit a meaningful change of impacts under alteration of ±10% LPG consumption. The findings underscore the environmental benefits of converting water hyacinth into bio-oil to address its ecological challenges while simultaneously enhancing sustainability.

水葫芦热解生产生物油的环境影响评价

可持续化学品的未来在于采用生物质转化等可再生资源。一种可以利用的独特生物质是水葫芦。除了能够克服河流污染，它的增值可以生产生物油。本研究对水葫芦热解的环境影响进行了评价。它采用生命周期评估（LCA）方法，以摇篮到闸门的系统边界和50kg生物油为功能单元。250 kg预处理水葫芦在400℃下热解，生物油得率为19.45%±1.02%。结果表明，由于液化石油气（LPG）需求量大，热解过程对环境的影响占66.2% ~ 99.7%。灵敏度结果显示，在±10%的LPG消耗量变化下，影响有显著变化。研究结果强调了将水葫芦转化为生物油的环境效益，以解决其生态挑战，同时提高可持续性。

期刊介绍： The Canadian Journal of Chemical Engineering (CJChE) publishes original research articles, new theoretical interpretation or experimental findings and critical reviews in the science or industrial practice of chemical and biochemical processes. Preference is given to papers having a clearly indicated scope and applicability in any of the following areas: Fluid mechanics, heat and mass transfer, multiphase flows, separations processes, thermodynamics, process systems engineering, reactors and reaction kinetics, catalysis, interfacial phenomena, electrochemical phenomena, bioengineering, minerals processing and natural products and environmental and energy engineering. Papers that merely describe or present a conventional or routine analysis of existing processes will not be considered.
