An Examination of Corn Fibre Use in the Construction Sector in Jamaica: An Alternative Paradigm in Building Material

Abstract

Introduction: There was an increasing emphasis on the construction industry’s need to adopt innovative practices that foster sustainability to mitigate the adverse effects of climate change. The construction industry is responsible for approximately 40% of global energy consumption and 37% of greenhouse gas emissions. As a result, the urgency for more sustainable building practices has become even more pivotal. One such alternative that remains underexplored is the potential use of corn fibre as a viable and sustainable material for construction in Jamaica.

Objectives: This study examines the viability of corn fibre as an alternative construction material in Jamaica and its mechanical properties, environmental benefits, potential applications, advantages and possible use in the construction sector.

Methods and Materials: The Systems Thinking Theory (STT), Life Cycle Assessment Theory (LCAT), and Social-Ecological Systems (SES) Framework guided this study. A standardised questionnaire was developed to assess the awareness of corn fibre as a suitable alternative between November 30, 2024 and December 18, 2024. A sample of 116 was drawn from the population of 1200 construction professionals using a stratified random sampling technique and a Chi-square test for statistical analysis.

Findings: The survey revealed that 68.5% of respondents were unfamiliar with corn fibre as a building substitute, with only 5.6% using it. Notably, those who had used it reported no difficulties in its application.

Conclusion: The findings indicate that further education and research are needed to address the knowledge gap and demonstrate corn fibre's practicability within the Jamaica construction industry.
