This review focuses on studying how plant fiber materials and bio-composites made from them impact the environment. The researchers aimed to assess the effects of using plant fibers in manufacturing products like composites. They found that plant fibers can be a good alternative to wood, which is running out due to environmental issues. The researchers analyzed how these materials affect the environment throughout their entire life cycle and identified ways bio-composites can be more environmentally friendly. They also looked at the costs of making and using these materials. Overall, the review highlights the benefits of using plant fibers and suggests there is potential for further research to make even better eco-friendly products in the future.
