A method of manufacturing pulp using corn stalks may include cutting the corn stalks into pieces having a length of 10 to 60 mm, separating and discharging the cut corn stalks into rind and pith using a separation unit while crushing the cut corn stalks, pretreating the corn stalks by filtering the rind and pith of the corn stalks and flakes of the rind, removing a portion of hemicellulose of the rind, and cooking the rind from which the portion of hemicellulose has been removed, using caustic soda and sodium carbonate.

Provided are purified ozonated medicinal cannabis non-hemp hurd fiber, and refined ozonated medicinal cannabis non-hemp hurd fiber, and compositions containing the ozonated medicinal cannabis non-hemp hurd fiber or refined ozonated medicinal cannabis non-hemp hurd fiber, the compositions including packaging products, molded pulp cartons such as egg cartons, smoking papers, paper packaging materials, single ply or multi-ply paperboard, absorbent paper products, and ink receptive papers.

Provided are purified Cannabis hurd fiber, and refined Cannabis hurd fibers, and methods for preparing cellulosic fiber from the hurd of Cannabis plants. The methods include decorticating the bast from the hurd, at least partially fibrillating the hurd fibers, abiotic retting of the hurd fibers, and exposing the hurd fibers to synthetic sunlight and ozonation to produce a purified hurd fiber. The purified Cannabis hurd fibers are substantially free of bast fiber, and have little to no pectin. Also provided are compositions containing the Cannabis hurd fiber or refined Cannabis hurd fiber, including packaging products, molded pulp cartons such as egg cartons, smoking papers, paper packaging materials, single ply or multi-ply paperboard, absorbent paper products and ink receptive papers.

The present invention has developed, unlike a conventional technology, an apparatus and a technique for rind, inside and scrap separation, which has been the greatest impediment to the mass production of high-quality paper-making pulp, thereby enabling the production of high-quality pulp, enables produced, unbleached pulp to be used as a raw material for manufacturing industrial packaging paper because of the excellent strength of the pulp, allows bleached corn chemical pulp to be suitable for the manufacture of toilet and facial papers and tissues, and can be applied to various paper-making techniques by mixing pulps, having different characteristics, such as needle bleached chemical pulp, leaf bleached chemical pulp, and bleached chemical thermomechanical pulp (BCTMP).

The present invention relates to pulp molded products including seaweed by-products and methods for producing the same. According to the methods of the present invention, pulp molded products including seaweed by-products are produced using apple pomace and/or green tea pomace. The presence of seaweed as a biodegradable and eco-friendly material and the addition of apple pomace and/or green tea pomace allow the pulp molded products to have natural antibacterial and anti-insect functions.

Disclosed herein are novel methods to prepare paper pulp from non-wood fiber sources, and preferably from a variety of different non-homogeneous fiber sources. The methods use a unique combination of caustic and temperature without a digestor to improve performance of the resulting fibers.
