Abstract
In this research, fibers were extracted from different parts of the okra plant (Abelmoschus esculentus) via water- and dew-retting methods. The fibers were subjected to physical and thermal analyses. The fibers obtained from the upper part of the okra plant showed higher breaking strength and lower linear density. Fibers obtained via water-retting exhibited higher breaking strength, higher elongation at break rates, and lower linear density values. The paper also presents the results of thermogravimetric analysis of the okra fibers. Tests were carried out in oxygen and inert gas atmospheres. Slight differences were found in the thermal resistance of the tested fibers, which was confirmed by an analysis using the αs-αr methodology. The calculated activation energy showed a widespread range of values.

The aim of this work is to investigate and compare the properties of okra fibers obtained thermal performance of okra bast fibers as they are processed under various conditions, and asfrom part various parts of the plant via dew-retting and water-retting
The okra fibers were obtained from various parts of the plant via water-retting and dew-retting procedures
Summary
Sustainable development (SD) is defined by the World Commission on Environment and Development as: “development that meets the needs of the present without compromising the ability of future generations to meet their own needs”, in the report “Our Common Future”, more famously known as the Brundtland Report [1]. EU legal regulations that limit and even eliminate the use of many existing technologies and materials in conventional industrial production, and by an increase in societal environmental awareness. That is why the search to improve eco-friendly production methods and invent novel ones, and the use of new material solutions, especially materials based on renewable sources, has become one of the most important tasks for science and technology today [2,3]. As the world is struggling with growing waste problems, new legal regulations are being introduced to guarantee the production of more environmentally-friendly materials. They promote new products that can be recycled or are naturally biodegradable. Biocomposites, i.e., materials in which at least one component is of natural origin are an important option because they can be utilized for energy recovery [4,5]
