Jute Geotextile – Advantages and Market Growth


Advantage of Jute Geotextile

Jute Geotextile is much cheaper than synthetic fibre. It is easy to blend with other natural material and synthetic fibres. Jute Geotextile is environmental friendly, biodegradable, hydrophobic, anionic and locally available materials. Initially it has got the high strength and non-hazardous properties. It is also a renewable source of energy as natural biomass.

Why Geotextiles ?

Geotextiles used in or near the ground to enhance the ground’s characteristics. Applications are usually in the field of civil engineering and environmental engineering and consequently the design of these applications is often closely associated with geotechnical engineering.

Designers of soil erosion control systems usually only need the geotextile to provide ground protection and to create a micro-climate for the seedlings until vegetation is established which is often for one or two growing seasons. Thus the durability of even low weight jute geotextiles is adequate in most cases and sisal would be expected to outlast jute. In cases of river banks or extreme applications where plant growth is expected to take longer then sisal would probably have an advantage.

Soil erosion has been occurring for some 450 million years, since the first land plants formed the first soil although it only became a serious problem in recent centuries because of the accelerated erosion. Erosion is often the result of human activity, such as unsuitable cultivation practices and forestry exploitation which leaves the land vulnerable during times of heavy rainfall and high winds. Often slopes are formed either by cuttings or embankment fills when roads or railways are built or when land is developed. For an economical earthwork and to reduce the area of un-productive land, steep slope angles are preferred, but, the steeper the slope the greater the risk of soil erosion. Soil erosion by water and wind is responsible for about 56 percent and 28 percent respectively of world-wide land degradation.

Geotextile Market Growth

The market for geotextiles is growing at an exceptional rate, and in the year 2000 some 1400 million square metres of geotextiles were sold. New applications are being found and new products developed at great rate. There is an established market for natural fibre geotextiles and in some applications they have characteristics superior to synthetics but they often come second best due to the ability of the synthetic geotextile suppliers in meeting users demands for technical data.

Sisal geotextiles could compete with other natural fibre geotextiles and would be expected to have some properties superior to other natural fibres. Further study of these properties should be carried out in order to establish a good data bank of knowledge and to also focus on those applications where synthetics have the monopoly and where prices paid are high. This work would benefit from the support and sponsorship of all sisal producing countries in order to catch up with the work already produced by the petro-chemical companies who manufacture synthetic geotextiles and to compete in this technical field.
