Abstract
The aim of this study is to investigate the effect of chemical treatment method on the properties of Posidonia fibers. The chemical treatment which is carried out is a combined hydrogen peroxide and sodium hydroxide treatment. First, an investigation of the treatment processes was undertaken. Secondly, the physical properties (linear density, diameter and ratio length per diameter), the mechanical properties (tenacity, elongation) and chemical properties (FT-IR spectra and X ray diffraction) of posidonia fibers were investigated. The optimum operating conditions were identified using a factorial design.

The issue of economic, social and environmental sustainability is present in discussions of all sectors of industry, since it is a constant search by improvements in living conditions of the population, and by maintaining a safe environment for present and future generations [1]
All fibers have a common structure, but their physical properties can vary in a substantial way depending on the method and conditions carried out for extraction
Summary
The issue of economic, social and environmental sustainability is present in discussions of all sectors of industry, since it is a constant search by improvements in living conditions of the population, and by maintaining a safe environment for present and future generations [1]. It has roots, a stem which is here rhizomatous, and banded leaf measuring up to one meter long and arranged in clusters of 6 to 7 It loses leaves in autumn, and the cast litter deposits can be found mainly along sandy coasts, forming wedge structures, from a few centimetres to several meters thick, denominated “banquettes”. This aquatic biomass represents an abundant, inexpensive, and readily available source of renewable lignocellulosic biomass for the production of eco-friendly industrial products It has received increasing attention in the last few years and it has been studied as: a low-cost adsorbent for removing dyes or phenol [6], a substrate for papermaking [7], a starting material for cellulose derivatives [8] and a reinforcement on composites [9]. The physical characterization (density and fineness) and mechanical toughness and deformation of these fibers are not yet studied
