PREAMBLE TO THE DESCRIPTION
The following specification particularly describes the invention and the manner in
which it is to be performed.

FIELD OF INVENTION
This invention relates in general to paper manufacturing with the help of Water Hyacinth which is a non wood plant.
BACKGROUND OF THE INVENTION
Paper is a fundamental part of most aspects of society; world-wide a total of approximately 300 million tons of paper are produced each day and approximately 90% of this paper is produced from mature pulp wood. In addition the demand of paper is expected to increase. Today the finest of papers are produced all over the world. But one dismaying fact is that millions of trees are fell in a day to make paper. Increased demands of paper production and limited wood resources have directed researchers to look for appropriate additional resources of non-wood materials for pulp and paper manufacturing.
OBJECTIVE OF THE INVENTION
The main object of this invention is to provide a novel paper and pulp manufacturing technique by a weed named Water Hyacinth (Eichhornia crassipes) which is readily available.
Another objective of this invention is to provide a further insight into more sustainable resource use and waste management practices.
Yet another objective of this invention is to understand and identify potential areas for improvement and to place these in a broader environmental context.
Yet another objective of this invention is to provide a pollution free, non wood paper to the society and to minimize the use of wood for the manufacturing of the paper.
Yet another objective of this invention is to provide employment to employers.
SUMMARY OF THE INVENTION
The embodiments herein provide a complete procedure, raw materials, and chemicals used. Basically, for this product we have used Water Hyacinth weed and waste paper as major raw

materials. We have used Water Hyacinth weed because it is a weed, it gives high strength to the product and it is having various problem regarding to environmental and to society such as, wastage of Water resources, rivers becomes clogged and in the rainy season floods occurs because the Water cannot drain from the area, people can no longer use the river to transport good, problem arises on fish market as fishe$ and other river creature die because of a lack of oxygen caused by the plant, local economy is affected, increasing in the number of mosquitoes which leads to malaria, cholera, Pilariasis.
In order to think positively about using Water Hyacinth for practical purposes, one must think positively about the plant. We have followed procedure as collection of weed, washing, blending, bleaching, addition of binding material and dyes, screening, pressing, and drying. Sulfate of Aluminum, Sodium hydroxide, Hypochlorous Acid, Starch, Calcium Oxide are we used for the purpose of Bleaching. We have also use rosin for sizing of paper and dyes for coloring.

Referring now to the figures wherein the showings are for the purpose of illustration of the invention only, and not for the purpose of limiting the same,
FIG 1: Shows the fibrous structure of stem of Water Hyacinth.
FIG 2: Shows the addition of blended material of both Water Hyacinth and Waste paper.
FIG 3: Shows the formed product after all the stages of bleaching.
FIG 4: Shows the final pulp ready for paper manufacturing.
FIG 5: Shows the screening of formed pulp.
FIG 6: Shows the product i.e. paper which is manufactured by Water Hyacinth weed.
DETAILED DESCRIPTION OF THE INVENTION
Initially we have to collected Water Hyacinth weed from the Morna River, Akola (M.S), India. As it is living in sand water so we've washed it carefully and then remove leaves and

roots of plant. We have only used the stem of the plant as it is having fibrous like structure and it is responsible for providing high strength to the product (Refer FIG 1). We have allowed stem of Water Hyacinth to be dried up to semi crispy and up to brown color formation for 5-6 days. After this we washed stem many a times and separately bleached it with Sodium Hydroxide (NaOH) which give properties like softening, pulping and pH maintenance. Then the bleached stems are blended with the help of blender. Separately we have waste paper, in the initial stage we cut down waste paper in small pieces, and then it is allowed for soaking in water for 2 hours. The socked waste paper is vigorously washed for 2-3 times and then formed pulp is blended rigorously. And now separately we are having blended stem of Water Hyacinth and blended water paper, these are allowed to mix up by hand thoroughly which is shown in FIG 2.
The next stage is very much important for the manufacturing of pulp and paper which is nothing but the bleaching. Initially we have used 1:1 proportion of waste paper and Water Hyacinth weed. As we have mentioned earlier, Sulfate of Aluminum, Sodium Hydroxide, Hypochlorous Acid, Starch, Calcium Oxide is being used for the principle of bleaching. In a process, blended material (cellulose fibers containing approximately 5% residual hgnin) produced by the pulping is first washed to remove some of the dissolved organic material and then further delignified by a variety of bleaching stages. First of all we have used Sulfate of Aluminum (i.e. Alum) for bleaching, it is used for the alkaline sizing and to separate sized particles in the formed pulp. Then the prime bleaching agent i.e. Sodium Hydroxide (NaOH) is been used in 3.5-4.0%, pulp is heated at around 65-70°C and pH is found to be 9.0-10.5. The key objectives for using NaOH as bleaching agent are to remove chlorinated and oxidized lignin formed in the chlorination stage, to remove resins and fatty acids, and to obtain stronger, brighter pulp, good cleanliness, and easier bleach ability in subsequent stages.
HOC1 is the next bleaching agent which is been utilized for bleaching and likewise for chlorination. After bleaching with NaOH, 1-2 washing by water is carried out. Further, chlorination stage is carried out. In this stage chlorine drops are added in the pulp mixture, retention time 30-60 minutes, temperature 50-65 °C. This stage is playing a vital role to increase brightness of pulp. Starch is next agent which is a polymer of glucose Pyranose unit linked with 1-4 glucosidic linkage. Starch is used as a surface sizing agent. It is applied to improve the surface of the sheet for the purpose of controlling ink receptivity and porosity; it

also increases the strength of paper. Then Calcium Oxide (i.e. Lime, CaO) is an important commodity for the pulp and paper manufacturing. Lime is used for pulping; because lime is highly alkaline, it dissolves the lignin that binds the fibers together. Until now bleaching process is carried out and the final product can be seen in FIG 3.
Further addition of binding material and dyes is carried out. Rosin mainly contain abietic acid is good adhesive agent used here for paper manufacturing. Dyes are used for coloring of pulp actually in the stage of bleaching; CaO is itself acts as coloring agent. Finally we are having formed pulp (FIG 4) which is then screened out which allows removing excess water and is shown in FIG 5. We carefully then port screened material on the platform and by means of weight, the remaining excess water is drawn out. Finally the pressed paper is dried in open air and final product is shown in FIG 6. The whole process is carried out in domestic level. We'll suggest to small scale industries for small production and if market value is getting good we'll suggest this novel technique for major production. ADVANTAGES Following are some advantages of paper manufactured by water hyacinth.
• Use of non-wood raw materials, thus saving trees.
• Made with pollution free methods as solar energy is used extensively.
• Acid free.
• Higher tensile, bursting, tearing and double-fold strength as compared to mill made paper.
• Fine and elegant quality.
The foregoing description is a specific embodiment of the present invention. It should be appreciated that this embodiment is described for purpose of illustration only, and that numerous alterations and modifications may be practiced by those skilled in the art without departing from the spirit and scope of the invention.
