Luffa Cylindrica: Sustainable industrial innovations

Abstract

In a global context marked by the rising demand for sustainable and biodegradable materials, natural fibres have gained unprecedented significance in scientific and technological research. Known for their low environmental impact and versatility, natural fibres offer innovative solutions to replace non-renewable synthetic materials. This study explores the trends from 2010 to 2023, focusing on the use of Luffa cylindrica, an alternative crop particularly relevant for emerging economies and rural communities. A total of 589 articles and 632 patents were analyzed using a bibliometric and patent review approach to identify industrial advancements related to this plant.

The findings reveal a 35 % increase in publications and a 40 % increase in patents related to sectors such as construction, pharmaceutical, biotechnology, and agriculture between 2010 and 2023, reflecting a significant growth in interest. Literature highlights its applications in lightweight construction materials, such as eco-friendly panels; acoustic insulation, including soundproofing in urban housing; and reinforced composites for automotive interior components, demonstrating its adaptability to diverse industries. Patent data underscores advancements in biotechnological applications, environmental engineering for water and air filtration, and agricultural innovations. Its potential for pollutant remediation, with absorption efficiencies reaching up to 90 % for heavy metals, and sustainable packaging solutions that could reduce reliance on synthetic plastics by an estimated 25 % in specific markets, positions this plant as a key renewable resource for promoting sustainability.

The evidence suggests that Luffa cylindrica has the potential not only to replace non-renewable materials but also to drive technological advancements in both emerging and established markets. This study emphasizes the importance of developing new applications while addressing these issues to support the transition to a circular economy and mitigate environmental impacts. The research contributes significantly to the development of cleaner, more sustainable industrial processes.
