  Kenaf
Kenaf is a member of the mallow (Malvaceae) family, with okra and cotton as relatives.
Kenaf plants grown in dense stands are largely unbranched and grow to a height of 8 to 14 ft and under certain conditions will reach 20 ft. The stem's outer bark contains the long soft bast fibers which are useful for cordage and textiles.
However, the kenaf plant tolerates a fairly high population of chewing and sucking insects, and since the production emphasis is biomass rather than root, seed, fruit or flower, the required level of insect protection for kenaf may be much less than for most commercial crops.

 About The Kenaf Plant
Kenaf is a 4,000 year old NEW crop with roots in ancient Africa.
U.S. Department of Agriculture studies show that kenaf yields of 6 to 10 tons of dry fiber per acre per year are generally 3 to 5 times greater than the yield for Southern pine trees, which can take from 7 to 40 years to reach harvestable size.
Upon harvest, the whole kenaf plant is processed in a mechanical fiber separator, similar to a cotton gin.

 Kenaf leaves
Kenaf leaves are used as animal feed and also as human food in some sauces of African and Asian cuisine.
Kenaf leaves, while being extremely variable from whole to lobed, so much as to be dissimilar even on the same plant, if examined carefully it will be seen they are formed of a single leaf - albeit deeply lobed - rather than several blades joined at a point as in the case of hemp leaves.
Hemp leaves, on the contrary to kenaf leaves, are sticky to touch and are a darker green on the top of the blade.

Kenaf’s advantage as a bedding material, while significant, is dwarfed by its performance as an oil absorbent.
Kenaf’s distinct preference for oil allows it to absorb oil to the exclusion of water when both liquids are present.
Kenaf’s superior absorbency allows replacement of expensive, imported sphagnum moss and coconut coir fibers as well as substitution for a significant percentage of either vermiculite or perlite in high-end soil and potting media.

 KENAF: A NON-WOOD PAPER ALTERNATIVE
Kenaf's value per acre of land, moreover, is greater than pine's since its fiber yield (6-10 tons of dry fiber per acre annually) ranges from two to five times higher than pine's.
Kenaf bast alone yields about as much pulp per acre as pine- which still leaves a heap of core fiber to be marketed for such products (in addition to paper pulp) as particle board, potting soil, poultry litter, horse bedding, and oil and chemical adsorbents for bioremediation.
Only eight percent of kenaf bark (and 13 percent of the whole stalk) is made up of the cellulose-bonding substance, compared with 30 percent for pine, which makes it considerably less energy intensive.

 Greene Natural Fibers - Kenaf Products   (Site not responding. Last check: 2007-10-03)
The kenaf plant contains two distinct fibers: bast, a long, stringy fiber similar in both appearance and performance to jute and hemp, and core, a light, spongy fiber which bears a resemblance to balsa wood.
Kenaf bast fiber comes from the outer layer, or bark, of the kenaf plant where it is naturally bound in a matrix of pectins – a family of low-grade structural polymers.
Once kenaf has been harvested, the object is to achieve complete separation of the plant’s two components in such a manner as to minimize total fiber loss and maximize each constituent component's quality while also rendering the fibers to a form which maximizes their market value.

 B1047 Evaluation of Kenaf Growth Media as a Substitute for Pine Bark
The objective of this study was to evaluate the effects of composting kenaf core, kenaf core particle size, and kenaf core:pine bark ration on the growth of Ilex crenata 'Compacta' and Rhododendron 'Sunglow' to determine the reliability of kenaf fiber core as a growth media component to produce containerized woody landscape plants.
And in noncomposted kenaf, growth was equal to pine bark with 'Compacta' holly and poor with 'Sunglow' azalea.
The use of kenaf as a component of growth media to produce container-plant crops that require at least one growing season appears to be limited because the poor stability of this material.

 Planet Ark : Kenaf popular as nonwood alternative for paper
Kenaf, the tall African plant that grows a pale yellow flower similar to the hibiscus, is becoming popular in Japan, touted as a source for paper pulp that is more friendly to the environment than wood.
Enthusiasts say kenaf is an ideal source for paper since the plant can reach a height of 3 or 4 meters in several months and absorbs more carbon dioxide than trees.
Other kenaf groups that have formed across the country are also selling seeds and paper-making kits through the Internet to schools, companies and local communities which want to grow the plant and have a try at making paper themselves.
