Life-cycle and environmental impact assessments on processing of plant fibres and its bio-composites: A critical review

From the beginning of humanity, our generation has been on the edge of finding suitable solutions to increase the product’s life-cycle and reduce the environmental impact of the product. Life-cycle assessment is a process to evaluate the effects of products or services whereas environmental impact assessment is an inter-related process of evaluating the environmental impact of a product or service. Plant fibre reinforced composites are developed by researchers, which are kindled by economic and environmental trepidations. The forest’s wood resources will decline and deplete due to environmental issues caused by natural and renewable resources. The main objective of this review is to conduct life-cycle assessment and environmental impact assessment studies on plant fibres and manufacturing of bio-composites from these fibres. It identifies the differences and causes to the environment, in particular about the total effect on the surrounding atmosphere. Another aim of this work is to assess a techno-economic feasibility based on the environmental impact category. In addition to this, inventory assessments of these composites are also dealt with, alongside the industrial applications. This review concludes a summary of current research and point out the opportunities and challenges for future researchers.
