What is the background of the study of cogon grass as cardboard food packaging?
Wiki User
∙ 10y ago
the cogon grass is first boiled and shredded,then mixed with used paper that has been previously washed. This mixture is cooked again in a large vat, cooled, laid out on homemade frames made with silkscreen, pressed for an even thickness, then dried. Considering the volume of cogon paper made, drying is sometimes both under the sun and with a dryer acquired through the grant.
The above is a recipe for papier-mâché, not paper. Real paper can also be produced from cogon grass, and just about any other cellulose source, by "cooking" in a caustic-soda solution and using the resulting pulp to make handmade paper by the usual process. See for instance the Dover edition of Dard Hunter's book: Papermaking.

∙ 10y agoThe study, "The Feasubility of Cogon Grass (Imperata Cylindrica) as an Economical and Environment-Friendly Substitute for Cardboard, Food Packaging, for Souvenirs, Etc," cut, boiled and crushed the cogon grass in order to get its pulp. They then tested three treatments of the grass, with the first group being the control. It was found that treatment C was the preferred treatment.

As the chalk dust may not always slide down into the bin you will need to jiggle and shake the tray a bit from time to time
2. So set up a low powered electric motor with a slow speed reduction gear attached to an eccentric disc under the tray such that the eccentric disc touches the tray at the upper end.
3. Every few minutes the tray will incline and decline like a rocking horse
4. Design the inclination angle such that the chalk dust freely flows at the highest inclination required

How effective Cogon Grass Cardboard Food Packaging?
The feasibility of cogon grass (Imperata cylindrica) as a substitute for cardboard food packaging was studied in this research project. The cogon grass was cut, boiled, and crushed in order to get the pulp. The pulp was then subjected to five different treatments before it was made into a card board like material. The amount of resin and other additives was kept constant while the amount of starch was varied in every treatment. Nonbiodegradable waste is a major concern everywhere in the world. The bulk of the world's waste consists of the hard-to-break-down products, such as styrofoam. Styrofoam is commonly used as food containers in fast food restaurants. Because it cannot be recycled, this particular waste contributes largely to the world's increasing garbage problem. To lessen this environmental problem, one logical solution is to use biodegradable materials or recyclable ones. Paper is being reconsidered and encouraged for use. This material can be recycled over and over again. However, trees still need to be cut for paper production. This spells trouble for the already depleted forests. Because of this, the researchers thought of another alternative. This alternative uses cogon grass for making the pulp and the paper. Cogon grass is found abundantly in many places and is sometimes considered a nuisance.

What is imperate root?
Imperate root is a brand name for the root of imperata cylindrica (also known as blady grass, cogon grass, kunai grass or Japanese bloodgrass) and is used in alternative medicine.
How do you lessen the growth of cogon grass?
Cogon is a perennial grass that spreads by rhizomes, making it very hard to eliminate. Periodic applications of herbicides such as Glyphosate (Roundup, Accord, generics) and Imazapyr (Arsenal, Chopper, generics) can provide temporary reduction in growth, especially when combined with frequent mowing. Tilling and then planting dense cover crops can help to smother the grass.
