Image courtesy of Greg Leach, International Paper: Decreased pine growth and survival in cogon grass-infested portions of pine plantation: Due to the damaging effects of cogon grass invasion, cogon grass is listed as a noxious weed by both the state and federal levels. Eight, (2011) stated that plant materials with 34% and, Comparison of fibre dimensions of the I. cylindrica with othe, Comparison of pulp and mechanical properties. For ash content, CG produced a value of 7.80 %, not much different from the literature of 8.24% reported by Kassim et al. The Mississippi Department of Agriculture and Commerce has assembled a task force of scientists, educators, government officials and agricultural leaders to recommend a comprehensive survey and control program for cogongrass (Imperata cylindrica) before the invasive weed overtakes pastures, forestland, wildlife habitats and landscapes in the state. Cogongrass [Imperata cylindrica (L.) Beauv.] Rice straw pulp obtained by using. DSC analysis demonstrated the effect of CNF on crystallization and crystalline morphology of PLA. The results of the physico-chemical analysis were within the range of those reported elsewhere for some non-woody pulping raw materials except solubility in cold and hot water was higher. An unusual characteristic of cogongrass is its flowering pattern. Scanning Electron Microscopy (SEM), is a good potential alternative fibre in the paper-based, C with 50% relative humidity for 24 hr. Results show that lignin content (5.67 %) and 1 % NaOH solubility (19.64 %) of cogon grass are the lowest compared to cocoa pod husk and oil palm leaf. INTRODUCTION. It is considered to be an invasive species in 73 countries and one of the “Top 10 Worst Weeds in the World,” cogongrass affects pine productivity and survival, wildlife habitat, recreation, native plants, fire behavior, site management costs, and more. Cogongrass has been used in Southeast Asia as forage because it is the dominant vegetation on over 300 million acres. External links are made available for the convenience of the internet user. The cogon grass was observed to wet oil almost instantly with sorption equilibrium time of 5 min. Rhizomes are much extended, equally noded and white. The kinetics and equilibrium capacity were investigated. This should be taken into account when filtrates are recycled ID the bleaching or washing of pulps. is a rhizomatous perennial grass that is among the most troublesome weeds worldwide (Holm et al. Increase fibre length and decrease cell, of I. cylindrica shows the highest tensile index (45.06. physical structure on the sheet produced. Currently very little information is available on totally chlorine free (TCF) bleaching. The ash of the plant is used as a … Make payments or register online to renew or obtain new licenses by selecting a keyword which best matches your license needs below. The chemical analysis of eucalyptus species reveal satisfactory levels of holocellulose (except Eucalyptus camaldulensis) and Klason lignin content (<30%) (except Eucalyptus camaldulensis and E.-348 hybrid). All figure content in this area was uploaded by Muhd. Cogon grass infestations can reduce pine survival and growth, and in fire situations, may result in complete mortality of overstory trees due to flammable oils in the grass blades raising the intensity and severity of prescribed burns. The most satisfactory properties of pulp and handsheets from bast could be attained by employing soda-AQ pulping with 19.4% active alkali, 0.10% AQ, and L:M ratio of 7:1 cooked for 2 hours at 160oC. CNF were first prepared through enzymatic and mechanical treatment of bleached hardwood kraft pulp. Increase in temperature with low concentration of H2O2 and HCl is found to improve the Milox pulping process. The most common extractives on the surfaces of fibers and fines were fatty acids, probably present mainly as triglycerides, and sterols and steryl esters. SEM images show that cogon grass fibres contained abundance and long fibres which provide good strength of the produced handsheet. All rights reserved. Kappa number (<22), pulp yield (>48%) and higher strength properties of E. grandis of Bhadrachalam and Saharanpur origins, Eucalyptus torrelliana, Eucalyptus camaldulensis and Eucalyptus alba showed their suitability for social forestry. Join ResearchGate to find the people and research you need to help your work. Meanwhile, fibre dimension were measured following the Franklin method. Effective cogongrass management options exist and depend on integrating several control strategies. The raw materials were characterised to know its properties. However, TPCS have some limitation such as poor mechanical properties. Cynara cardunculus L. – a new fibre crop for pulp and, consumption for Malaysia. Based on this quantification, I. of the pulping process are the pulp yield and fi, Table-3 shows the yield, tensile index, tear index a, by the low amount of lignin in the materia, parameters for the direct measurement of paper strength as, reported in Table-3. A brightness of 82.4-90.4% ISO was achieved with moderate charge of peroxide. Younger cogongrass shoots are very susceptible to these herbicides; however, longer term control of adult plants requires translocation and thereby control of the rhizomes. Because of the large geographic area infested with cogongrass and the often economically and environmentally unacceptable management techniques, biological control organisms also should be researched. Non-woods derived fibre could be good candidates due to its abundance availability. [ Allow 12 inches of re-sprout before applying herbicide.Most managers recommend a foliar application of 2% glyphosate (e.g. Composites of recycled low-density polyethylene obtained from waste water-sachets and imperata cylindrica were produced with particulate and long-fibre unidirectional mat reinforcements. stalks. It is used for thatching the roofs of traditional homes throughout south-east Asia. The state of Florida neither endorses links nor approves of links to external sources. abundant, sustainable, recyclable and biodegradable in nature. Flowering. Cogon Grass. properties remain unknown. The leaf blades have a midvein which is clearly offset to one side, and serrated (toothed) edges. To examine the thermal condition throughout studied circular plate with the range of temperature that related to industry’s operation by using ANSYS software. All services require an appointment. In this paper, highly porous and mechanically strong cellulose aerogels were successfully prepared from microcrystalline cellulose and dissolving pulp in ionic liquid BmimCl via a sol-gel polymerization method. The amount of metals ID the pulp and on the pulp surface decreased when pH was lowered to 2. Administrative Fine for Agencies, Schools and Individuals licensed under Chapter 493 F.S. ©2006-2016 Asian Research Publishing Network (ARPN). The selected grass species had well developed fibrous sheath around the vascular bundles.

Oil palm plantation generates massive amount of oil palm empty fruit bunch (OPEFB) which source great amount of cellulose. See list of regulations and ordinances. AFM showed the precipitated material as a granular phase. It is therefore imperative to investigate its antibacterial and antioxidant properties. . Leaves are flat, linear-lanceolate, 20 to 50 centimeters long, and 5 to 9 millimeters wide, stiff with scabrous margins. Water-sachets made from low density polyethylene (LDPE) form a bulk of plastic wastes which creates environmental challenges, while certain species of plants like Imperata cylindrica constitute large portion of weeds on farm lands. The cogongrass can be mistakenly baled with the hay if farmers aren't careful to keep it out of other grass fields. The aim of this study was to bleach pulps to high brightness, while retaining sufficient strength properties. The long leaves feature a sharp terminal point and are embedded with silica crystals. ex Steud., Saccharum arundinaceum Retz., S. spontaneum L., Setaria glauca (L.) P. For about four weeks following a prescribed burn, crude protein of regrowth is comparable to bahiagrass.
