“…This is exactly one area where more research efforts are being developed in the last years in fields such as roots and plants biotechnical characteristics such as their structural and dynamic behavior (e.g., Ali, Reineking, & Münkemüller, ; Boldrin, Leung, & Bengough, ; de Baets et al, ), modeling, either in slope stabilization (e.g., Gonzalez‐Ollauri & Mickovski, ; Mao et al, ; Tardío & Mickovski, ) and riverbank protection (e.g., Woolsey et al, ; Bariteau et al, ), or developing and assessing the complementary action of inert materials and structures used in combination with plants in particular circumstances (e.g., Sanyal, ; von der Thannen et al, ).…”

This paper analyzes the concept of nature‐based solutions as instruments to turn anthromes more nature compatible, efficient, causing less degradation, and developing new biodiversity hotspots. It is mainly focused on solutions using living organisms (in particular plants and microorganisms) to perform functions such as those of soil‐ and water‐bioengineering interventions in order to ensure the safety of human infrastructures and constructions in contexts of conflict between natural processes and human needs. Further, it handles the problematic of reintroducing natural processes and functions in the built environment (urban, industrial, infrastructures, etc.) in order to recover, recreate, or reinvent nature in humanized landscapes and developing a more creative relation between humans and natural elements, processes, and functions. It presents, furthermore, the contribution of natural solutions to a wide variety of decontamination processes and prevention and recovery of degraded land and natural resources. Finally, we discuss the way these solutions can be implemented and the cultural, organizational, administrative and governance, paradigmatic, and practice changes it implies. Examples are given on the different issues presented as well on the possible implementation solutions.

Composite materials are materials that are the combinations of at least two different materials or phases. Jute is a plant that can also be utilized as a composite reinforcing phase to form a composite structure. Recently jute composites are preferred in many areas because of their low cost, low density, ease of availability and renewability. Thermoplastic and thermoset resins can be used as matrix phase to form a jute composite. In this experimental study; epoxy and polyester resins were combined with several woven jute plies to form composite laminate. Plies were treated first with 2.4 liters of deionized water and 240 grams of sodium hydroxide for 4 hours. After this step, 6 liters of deionized water and 10 % diluted acetic acid were applied to woven ply. Before and after these chemical steps, microstructure changes were observed by the help of an optical microscope. Resin and hardener of polyester and epoxy polymers were prepared in specific ratios before applied to jute fibers. These mixtures were applied to fabric plies by hand layup method. After applying polymer mixtures to laminated fabrics, hot press was used for curing at 100 °C, 4 hours and 0.5 ton pressure. Thickness of the plies was measured before and after the chemical treatment and also after the curing process and hardness of the cured laminate was also measured by using Durometer. Microstructural changes of jute fibers in terms of dimensions were analyzed to see if the chemical treatment played a role in the dimensional changes. Investigation of microstructural changes and physical properties of jute fibers before and after treatment of sodium hydroxide and acetic acid are one of the main focus of this research. It was observed that thicknesses of jute fabric plies were increased after treatment by sodium hydroxide and acetic acid treatments. According to the study, treatment of jute fabric plies with sodium hydroxide has increased their length while treatment of the same fabrics by acetic acid after the sodium hydroxide treatment decreased the same dimension. Another observation was made for the usage of polyester and epoxy for the impregnation of the jute fabrics and also the ease of use for small amounts of polymer. It was seen that more amount of polyester is needed than epoxy to wet the same amount of area and while a high speed mixer could be employed for mixing the two component epoxy, three component polyester cannot be mixed with the same device and hand stirring should be employed for this purpose which uses low mixing rate.

“…The use of natural fibers is growing in many fields by materials producers and industries such as automobiles, furniture, packing and textiles due to their good mechanical properties and the fact that they are environmentally friendly compared to synthetic fibers. [1][2][3] The natural fibers can be extracted from two sources: the protein fibers and the cellulose fibers. The cellulosic fibers are taken from fruits such as coconut 4 or from parts of plants such as sisal, kenaf, pineapple, jute, hemp, palm, sabai and others [5][6][7][8] The cellulosic fiber is composed of many components such as cellulose micro-fibrils which play the role of reinforcement and other components such as hemicellulose, lignin and pectin which play the role of matrix responsible for the cohesion between the micro-fibrils.…”

In the last two decades, an increasing interest has been observed for the use of natural fibers such as jute fibers in different applications. These fibers are characterized by their low cost and their availability. They are mainly used in fabric bag manufacturing. The objective of this paper is to study the effect of temperature on the mechanical properties of jute yarns. An experimental study was conducted at different temperatures (22 °C; 80 °C; 105 °C and 150 °C) for 24 h. Each degree was followed by tensile testing of the specimen. Besides, the thermo-gravimetric analysis (TGA) was used to investigate the effect of the temperature on the thermal stability and the thermal degradation of the jute fibers. In addition, the statistical analysis was performed using the method of two and three-parameter Weibull distribution to determine the spatial distribution of the properties. The results showed that there was a degradation of the mechanical properties of the jute yarns heated to high temperature compared to the raw yarns (considered as a specimen exposed to 22 °C). The tensile strain and the Young modulus failed by 36% and 13% respectively for the specimens heated at 150 °C and the failure kinematic of the jute fiber was affected by the temperature of heating. The TGA showed that the thermal stability of the jute yarns was affected by two factors: fibers drying and their changing temperatures.
