Jute is made from the stems of the jute plant. The fiber is coarse and rough, providing a durable material. The process of making fabric from the jute plant is generally energy efficient. The jute fiber can also be recycled several times before it is no longer useful. After cotton, jute is the most important and most useful plant fiber, it can be mixed with wool and cotton, but also with synthetic materials. Since jute is not as attractive to pests as the cotton plant is, it does not need to be treated as harshly with pesticides. It is also more efficient to harvest when the whole plant can be used, unlike cotton where only the fibers from the protective seed casing are used.
