Description

EXAMPLE

1°) Cocoa Tree Vegetable Paper

[0137] A vegetable paper according to the invention comprising fibres originating from cocoa tree was manufactured according to the following method: cocoa husks were ground using a knife mill so as to obtain particles about 1 mm in size. The ground husk material was then mixed with water at 70° C. for 20 minutes, in a husk/water ratio of ⅒. The mixture is then centrifuged so as to separate the aqueous part (cocoa husk fluid) from the insoluble part (cocoa husk fibres). The fibrous fraction is refined using a disc refiner. After refining, delignified fibres originating from resinous trees are added to the refined fibre fraction according to the invention in a ratio of delignified fibres/fibres according to the invention from cocoa tree of 40%/60% so as to manufacture vegetable paper sheets. The vegetable paper sheets are then dried on a hotplate.

2°) Coffee Tree Vegetable Paper

[0138] A vegetable paper according to the invention comprising fibres originating from coffee tree was manufactured according to the following method: the films surrounding the coffee grains were mixed with water at 70° C. for 20 minutes, in a film/water ratio of ⅕ by weight. The mixture then undergoes an extraction step in a hydraulic press to separate the aqueous part (coffee film fluid) from the insoluble part (coffee film fibres). The recovered insoluble part is heated a second time at 70° C. for 10 minutes with an insoluble part/water ratio of ⅕ by weight. After an additional extraction (by pressing), the sample is refined using a disc refiner. After refining, delignified fibres originating from resinous trees are added to the refined fibre fraction according to the invention in a ratio of delignified fibres/fibres according to the invention from coffee tree of 10%/90% so as to manufacture vegetable paper sheets. The vegetable paper sheets are then dried on a hotplate.

3°) Tea Tree Vegetable Paper

[0139] A vegetable paper according to the invention comprising fibres originating from tea tree was manufactured according to the following method: black tea leaves were mixed with water at 70° C. for 20 minutes, in a tea/water ratio of ⅕ by weight. The mixture then undergoes an extraction step in a hydraulic press to separate the aqueous part from the insoluble part (tea fibres). The recovered insoluble part is heated a second time at 70° C. for 10 minutes with an insoluble part/water ratio of ⅕ by weight. After an additional extraction (by pressing), the sample is refined using a disc refiner. After refining, cellulose fibres (mixture of abaca, resinous tree pulp and broadleaved tree pulp in a 60/10/30 ratio) are added to the refined delignified fibres in a ratio of delignified fibres/fibres according to the invention from tea tree of 10%/90% by weight so as to manufacture vegetable paper sheets. The vegetable paper sheets are then dried on a hotplate.

4°) Green Tea Vegetable Cardboard for Secondary Wrapping (Tea Carton)

[0140] A vegetable cardboard according to the invention comprising fibres originating from tea tree was manufactured according to the following method: green tea leaves were ground using a knife mill so as to obtain particles about 1 mm in size. The ground leaf material is then mixed with water at 70° C. for 45 minutes, in a ground tea leaf/water ratio of ⅒. The mixture is then centrifuged so as to separate the aqueous part (tea leaf fluid) from the insoluble part (tea fibres). The insoluble part is refined using a disc refiner. After refining, delignified fibres originating from resinous trees are added to the refined insoluble part in a ratio of delignified fibres/refined insoluble part of 50%/50% so as to manufacture the vegetable cardboard. The cardboard is then manufactured on a paper machine at a grammage of about 275 g/m.sup.2.

5°) Cocoa Vegetable Cardboard for Secondary Wrapping (Chocolate Box)

[0141] A vegetable cardboard according to the invention comprising fibres originating from cocoa tree husks was manufactured according to the following method: the husks were ground using a knife mill so as to obtain particles about 1 mm in size. The ground husk material was then mixed with water at 70° C. for 45 minutes, in a husk/water ratio of ⅒. The mixture is then centrifuged so as to separate the aqueous part (fluid originating from the cocoa tree husks) from the insoluble part (cocoa husk fibres). The insoluble part is refined using a disc refiner. After refining, delignified fibres originating from resinous trees are added to the refined insoluble part in a delignified fibres/refined insoluble part ratio of 50%/50% so as to manufacture the vegetable cardboard. The cardboard is then manufactured on a paper machine at a grammage of about 250 g/m.sup.2.

[0145] A vegetable paper according to the invention comprising fibres originating from tea tree was manufactured according to the following method: green tea leaves were mixed with water at 70° C. for 20 minutes, in a tea/water ratio of ⅕ by weight. The mixture then undergoes a step of extraction in a hydraulic press to separate the aqueous part from the insoluble part (tea fibres). The recovered insoluble part is heated a second time at 70° C. for 10 minutes with an insoluble part/water ratio of ⅕ by weight.
