Scanning Electron Microscopy (SEM) was used to visualize the surface morphology of I. cylindrica hand sheet. Aerial view of expanding cogon grass infestation (light and green colored patches) following harvest of timber stand in NW Florida. 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. Cogongrass(Imperata cylindrica) is an invasive, non-native grass that occurs in the Southeast region of the United States. Results indicate that the cellulose aerogels with high degrees of polymerization have much better mechanical strength and adsorption properties than the cellulose aerogels with low degrees of polymerization. It is abundant, yet unsuitable for grazing animals and lacks a good commercial value, 1. Other applications were also reported such as for the preparation of biosilica [11], bioethanol [12] and as a potential source of non-wood fiber for paper making. Final brightness and viscosity values showed that by using a Q1(PO)Q2P sequence, bast, core and all blend fibres can be bleached to high brightness while retaining sufficient viscosity. Biodelignification process was applied to remove lignin in pulp and paper industry. This federally regulated noxious weed grows rapidly, reducing forest productivity, harming wildlife habitat and ecosystems, and encroaching on pastures and hayfields. The state of Florida neither endorses links nor approves of links to external sources. 1-800-HELP-FLA (1-800-435-7352) or 1-800-FL-AYUDA (1-800-352-9832), Mon.–Fri. The bulk density and ash content of the prepared carbon was 0.34 g/ml and 7.80 %, respectively. Cogongrass is a perennial grass that varies greatly in appearance. The experimental data regarding the results of, and C.tatarial (70.5%). The aim of this study was to bleach pulps to high brightness, while retaining sufficient strength properties. To investigate the natural frequency and mode shape of thermally stressed plate by using Functionally Graded Materials (FGM). The effect of the pulping time (10 to 120 minutes), temperature (120°C and 150°C), concentration (8% and 12%) and cooking liquor (soda and soda-ethanol) on the pulp yield and Kappa number of Nypa fruticans petiole pulps were investigated. It was seen that bast, core and all blend fibres exhibited great strength characteristics that were suitable for papermaking. Division of Licensing Regional Offices have reopened to the public. All Florida Department of Agriculture and Consumer Services offices are currently closed to the public until further notice. Eucalyptus grandis of Bhadrachalam and Saharanpur origins give very good fibre dimensions, especially slenderness ratio, which is directly comparable to Pinus kesiya. All rights reserved. Thermoplastic cassava starch (TPCS) is a promising alternative material to replace the non-biodegradable petroleum based polymer due to its good environmental-friendly aspect i.e. Roundup/Accord), or 1-1.5% imazapyr (e.g. Fairly sweet, the taste is sweetest in the wet season in Australia and worst from plants growing in sand. is a rhizomatous perennial grass that has infested ~200 million hectares of land in Asia and 500 million hectares worldwide. Cynara cardunculus L. – a new fibre crop for pulp and, consumption for Malaysia. FTIR spectra revealed the presence of aromatic rings of lignin and some aromatic compounds associated with CH. Var. The seed head is fuzzy, white, and plume-like (see images above). For about four weeks following a prescribed burn, crude protein of regrowth is comparable to bahiagrass. Other eucalyptus species have shorter fibres and narrow lumen with thick wall resulting to poorer flexibility, higher Runkel ratio and rigidity coefficient. This study conclude, based on the chemical and physical properties, the cogon grass, cocoa pod husk, and oil palm leaf are suitable to be used as alternative fibre resources in pulp and paper-based industries with various applications such papers, boxes and craft materials. The cogon grass was observed to wet oil almost instantly with sorption equilibrium time of 5 min. ... Table 1 presents some physical and chemical properties of CG. Cogongrass (Imperata cylindrica) is an aggressive colony-forming perennial grass, often forming circular infestations. 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. Younger cogongrass shoots are very susceptible to these herbicides; however, longer term control of adult plants requires translocation and thereby control of the rhizomes. 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. Comparison between the pulping rate of soda, soda-AQ Kraft and Milox processes is carried out. Non-woods derived fibre could be good candidates due to its abundance availability. Between the unbeaten bast and core soda-AQ handsheets, the strength properties of the core were higher than the bast, as the thin-walled core fibers exhibited much better conformability than the thick-walled bast fibers. Based on the chemical and surface morphological properties analyses, cogon grass is a good alternative fibre resource especially for pulp and paper making industries. ... Cogon grass is one kind of rhizomatous perennial grass which covers large areas of forest land throughout moist tropical regions, and it is widely distributed in Asia and in the USA [7]. The surface morphology and physical properties were characterized. Most of the precipitated lignin was found on the pulp surface after sheet forming, whereas the main part of the precipitated extractives could be easily washed away with water. The grain is oblong, pointed, brown and 1-1.5 mm long. When fully mature, its overall nutrient decline and its sharp pointed seeds and tangled awns may injure animals and humans, ... Its value more than 33 is considered good for pulp and paper making (Xu et al, 2006). fibers were selected and measured in this study. 2. The objective of this study is to determine the potential of non-wood plants as alternative fibres for pulp and paper-based industries based on its chemical and physical properties. Currently very little information is available on totally chlorine free (TCF) bleaching. Spikelets are numerous, 3.5-5.0 mm long, each surrounded by a basal ring of silky hairs 10 mm long. In addition, lignin content of tobacco stalks was lower than that of hardwood. Allow 12 inches of re-sprout before applying herbicide.Most managers recommend a foliar application of 2% glyphosate (e.g. 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. Other than dried and ground for smaller size, no notable treatment was performed on the cogon grass. The solubility in cold and hot water, 1% NaOH and ethanol-benzene were determined. It gives an insight of this underutilized, Fruticans petioles. 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. Oil palm plantation generates massive amount of oil palm empty fruit bunch (OPEFB) which source great amount of cellulose. The combination of these otherwise challenging resources in composite materials development will add economic value to them and help to reduce the nvironmental menace they present. Vegetative reproduction is the primary mechanism for survival and local spread, and sexually produced seeds of this obligate outcrossing species provide natural long-distance dispersal. O. Ktze collected from district Papumpare to evaluate their suitability as a raw material for pulp and paper making. Property Listings Blog Latest Posts. The pH slurry value was near neutrality (6.48). Cogongrass grows in loose to compact bunches, each ‘bunch’ containing several leaves arising from a central area along a rhizome. View COVID-19 Information. Therefore, in the present study, cogon grass fibre (CGF) were incorporated into TPCS using compression molding. More metals, such as Ca and Mg, were detected ID the pulps as well as on the sheet surfaces when the pulp was diluted with Z filtrate. The results showed an increase in tensile modulus, hardness, impact strength, and water absorption of the composite in comparison with unreinforced polymer, as the IC particulate loading increased from 5 wt% to 30 wt%. Root - fibrous but pleasant to chew, containing starch and sugar. Cogon Grass. Scanning Electron Microscopy (SEM), is a good potential alternative fibre in the paper-based, C with 50% relative humidity for 24 hr. The derived indices like Runkel ratio, flexibility coefficient, slenderness ratio, Luce's shape factor and solid factor were also evaluated and were compared with that of Bambusa tulda, a promising bamboo species in NE India for pulp and paper making. Generally, pulp yield and Kappa number decreases with the increase in the temparature, concentration concentration of the cooking liquor and time. Prior to air-dried, these samples were cut (2-, standard methods: hot water solubility (T, isothermally cooked for another 120 min as shown in. Young infestations are usually easier to control than older well-established infestations. weight, thermal properties, surface morphology, mechanical and wettability properties of the PLA-CNF nanocomposites were evaluated. Neither surface morphology nor surface coverage depended on the addition of Z filtrate. The surfaces of flake-like fines proved to be mainly covered with granular lignin and cellulose fibrils. Non-woody plants are potential sources of raw material for pulp and paper and supplement the depleted wood fibre resources. 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. The surface morphology of hand sheet was also visualized. Lignin and extractives precipitated at pH values below 6, and their amounts increased with decreasing pH. Moreover, among the three alkaline pulping processes-kraft, kraft-AQ, and soda-AQ-the results of pulp and handsheet properties showed that the soda-AQ pulp was comparable or even slightly of higher quality than the kraft pulps. By E-mail Full Text Pdf The leaves originate directly from ground level and range from one to four feet in length. Cogon grass (Imperata cylindrica Beauv. At both concentrations and temparatures, soda liquor gave lower pulp yield with higher Kappa number while soda-ethanol gave higher pulp yield with lower residual lignin. Eleven eucalyptus species are characterized for morphological, chemical, pulp and paper-making characteristics to get high pulp yield of good strength through social forestry in north Indian topological conditions. FESEM micrograph of cogon grass showed jagged and rough surface. After heating to, One-pot in situ polymerization approach was explored for the preparation of polylactide (PLA)-cellulose nanofibril (CNF) bio-nanocomposites. SEM images of I. cylindrica hand sheet at magnifications of: (a) 500x and (b) 1000x. CNF were first prepared through enzymatic and mechanical treatment of bleached hardwood kraft pulp. Apply herbicide by spraying all foliage just until wet to the point of run-off. The oil sorption was performed in a batch adsorption system. . The most common extractives on the surfaces of fibers and fines were fatty acids, probably present mainly as triglycerides, and sterols and steryl esters. In these areas it was found that only very young shoots should be grazed or cut for hay. The bio-nanocomposites- were then fabricated through ring opening polymerization (ROP) of L-lactide, in the presence of various amounts of fibrils. Native to Southeast Asia, the story of cogon grass in America begins around the Grand Bay area of Alabama in 1912 when it escaped from a Satsuma orange crate and began growing wild. However, wrapping this cellulose is an adhesive compound called lignin. 1.4 MB cular plate with various boundary conditions – vacuum, finite (boundary) & infinite air surrounding. The increasing demand in wood fibre consumptions especially in pulp and paper making has pushed forward the search for alternative fibre resources. Imperata cylindrica is the most morphologically variable species in … © 2008-2020 ResearchGate GmbH. The highest result of chemical analysis was recognized at run 12 (1.15%), 10 (12.35%), 4 (48.99%) and 5 (1.28%) for extractive, lignin, cellulose and ash content respectively. 1. To examine the thermal condition throughout studied circular plate with the range of temperature that related to industry’s operation by using ANSYS software.

From the study it was found that, the incorporation of CFG has improved the tensile and flexural properties of the TPCS composites, while the impact strength and elongation were reduced. The selected grass species had well developed fibrous sheath around the vascular bundles. Otherwise, re-treat regularly whenever adequate foliar re-sprout has occurred. Relatively increased (>25%) lignin content except E.-413 (hybrid) might require additional pulping time and chemical charge compared to other species. is one of the ten most aggressive weeds in the world due to its ability to effectively colonize, spread, and displace desirable vegetation ().Imperata cylindrica is a species of grass in the family Poaceae. It affects the lives of vegetation around, wildlife habitat, recreation, site management, and even native plants that can only be found in specific places. The state of Florida takes no responsibility for a link's operation or content. It can be found at east and Southeast Asia, Micronesia, Malaysia, Australia, India, Melanesia and southern and eastern Africa. Based on the chemical and surface morphological properties analyses, cogon grass is a good alternative fibre resource … The chemical and mechanical properties of the produced pulp from different pulping processes were examined. Grass is 1-5 ft. tall, often leaning into mats when over 3 ft. tall, tufts of long leaves, yellow-green, blades with off-center midvein, silver plumed flowers and seeds in spring, arising from sharp-tipped white-scaly rhizomes. SEM images show that cogon grass fibres contained abundance and long fibres which provide good strength of the produced handsheet. Australian Journal of Basic and, alkaline pre-impregnation and pulping on Malaysia, management. Based on the results, all the selected grasses species have fibres with desirable derived indices and can be used as an alternative source of raw material for pulp and paper making. Improved modulus for the nanocomposites with respect to standard PLA was demonstrated, however, the differences in tensile stress were small probably due to the counteracting effects of reinforcement from CNF and the decreasing molecular weight as a function of CNF concentration. The nutrients in wheatgrass aid the body in getting rid of impurities and … Early seedling establishment, prior to rhizome development, is low (< 20%), occurring in areas with little competition; ≥ 75% bahiagrass sod cover is required to prevent cogongrass seedling establishment. Meanwhile, the physical properties (fibre length and diameter) were determined according to the Franklin method. Don't Edit Non-wood plants were examined as alternative fibre due to the limited origin resources in paper production. 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). The effects of contact time, dosage of adsorbent and oil retention were investigated. Stems are solid, rather slender; nodes glabrous or bearded. Several studies having developed algorithms to detect cogongrass from other grasses in pa stures using hyperspectral data (Mathur et al., 2002 ; Huang et al., 2001 ) However, there has been no attempts to quantify cogon grass in longleaf pine savannas, which have a unique set of highly divers e species compared to savannas. It grows in tropical, subtropical, and some temperate regions of the world (Bryson and Carter 1993). This study may provide an insight on the usefulness of cogon grass for removal of engine oils.

Cogon grass (Imperata cylindrica) is an invasive, non-native grass which occurs in Florida and several other southeastern states. Non-wood fibres are increasingly being used in the pulp and paper industry to help meet the increasing world demand for pulp and paper. It was seen that bast, core and all blend fibres exhibited great strength characteristics that were suitable for papermaking. Cogongrass has been used in Southeast Asia as forage because it is the dominant vegetation on over 300 million acres. [ This creates opportunities to reduce LDPE wastes and add economic importance to an otherwise agricultural menace. Cogon grass spreads readily on disturbed sites and through movement of soil contaminated with small pieces of rhizome or seed (often due to site disturbance in timber harvest, site preparation, road grading, use of contaminated fill dirt, etc.). Mechanical control alone provides short-term control, whereas multiple discings plus herbicide application provide longer term control. Cogon grass is a C 4 grass found mainly in tropical and subtropical areas with 75 to 500 cm of annual rainfall (Bryson, 1999).  (article first appeared in Florida Forests Magazine), Invasive Species Identification and Control Guides, Jeffrey EickwortEntomologist and Supervisor(352) 395-4689Jeffrey.Eickwort@FDACS.gov, Chris PearceBiologist and Survey Coordinator(352) 395-4690Christopher.Pearce@FDACS.gov, Allen PercifieldSouthern Pine Beetle Forester(352) 395-4642George.Percifield@FDACS.gov, Florida Forest ServiceForest Health SectionDoyle Conner Building1911 SW 34th St.Gainesville, FL 32608-1201. The inflorescence is a white, spike-like panicle, terminal, fluffy, 5-20 cm long and up to 2.5 cm in diameter. 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. For newer patches, tillage can eliminate cogongrass from an area if continued during the course of a growing season.
