Abstract:

This paper uses sectional data to analyse the structure of papermaking industry and its environmental influence. In the other hand, this paper uses statistical data in 1992-2010, and takes the energy and water consumption, waste gas, SO2, mist and dust, waste water, COD, the solid waste discharge per 104 RMB Yuan as indexes. The relation between these indexes and economical development is analyzed with the technical advancement and the environmental protection consciousness enhancement, and the statistical model of papermaking industry is established. According to these models, the potentials of saving resources and reducing pollution are calculated. The results are showed that: with economic development, each index is falling by power model, and the relevance presents is high. The environmental loads of different periods gradually drop, because the technical is progressing and the people’s environmental protection consciousness is enhancing. The potentials of saving resources and reducing pollution are falling in papermaking industry, but the potential of present stage is high. This provides scientific foundation for the realization of paper-making industry clean production and envitronmental friendly economy.

Abstract:

Influences of self-developed additives WEC02/WEC03 on sizing of mechanical pulp are analyzed in this study. The results indicated that the optimal dosage for paper sizing were 0.2% (w/w) for WEC02, with sizing degree of 33 s, and 0.8% for WEC03, with sizing degree of 52 s. In addition, the combined usage of WEC02 (0.2%) and WEC03 (0.6%) at pH7.0 could get better sizing performance than single application of WEC02 or WEC03 with sizing value of 77 s. It is obvious that WEC02/WEC03 have great potential to improve sizing efficiency in neutral paperrmaking, leading to saving the sizes dosage and cutting down the production cost.

Abstract:

The dominating role of colloid science in papermaking processes, as exemplified by wet-end chemistry, is now well known. The concept of colloids dates back to about 160 years ago. In certain cases, however, the term “colloids” can have an overlapping meaning with the modern terms “nanomaterials” and “supramolecular assemblies”. The latter terms, and the scientists who have gravitated to those terms, have enriched colloid science, providing new insights into colloidal systems. It is proposed here that reconsidering papermaking in light of these multi-disciplinary sciences has potential to facilitate effective teaching and learning pertaining to universities that have pulp and paper programs. Enhanced integration of basic sciences with papermaking may further our understanding and broaden existing research areas, which is likely to create breakthroughs in basic research, applied research, and product development.

Abstract:

The influence of nanofibrillated cellulose (NFC) was investigated as a reinforcing agent to improve strength properties of papersheets fabricated from recycled pulp fibers of mixtures of old newspapers, old magazines, and old corrugated cardboards. To determine the effects of the NFC on the mechanical and physical properties of the recycled pulp papers, cellulose nanofibrils (NFC) were isolated from wheat straw, pretreated chemically and enzymatically (NFC-OX), and then added to the bulk suspensions of papermaking pulp slurries at various percentages. The electrokinetic and drainage properties of the pulps and the mechanical and physical properties of the papersheets were analyzed and compared. As expected, the addition of NFC/NFC-OX significantly increased the strength properties of papers. Papers containing 4% of NFC-OX (periodate pretreated) presented higher increases in tensile index (43%) and burst index (59.3%) than other papers. However, a high addition of NFC/NFC-OX increased the water retention, which is undesirable for papermaking. Hence, with optimum selection of NFC/NFC-OX and process conditions, higher mechanical properties could be acquired without increasing drainage rate. Compared to the other pretreated NFC/NFC-OX types, sodium-periodate-oxidized NFC-OX samples significantly increased the mechanical properties of the papers fabricated from the recycled pulps.

Abstract:

While much effort has been focused on optical properties imparted by particle size distribution, shape, and packing of inorganic particles, the refractive index contrasts within the paper matrix have received less attention. PCC fillers can be used as tools for increasing the refractive index contrast, which further improves paper optical properties. We studied the papermaking potential of novel PCC fillers with an enhanced refractive index. PCC samples were fabricated by conventional carbonation method in the presence of refractive-index enhancing additives. We had previously found that introduction of ZnO as fine spots, including nano-sized structures, on host PCC surfaces improved the effective refractive index and optical performance of PCC. Now, we have studied the papermaking potential of this approach in experiments with handsheets using moderate Zn modification. In addition to Zn, we studied the effect of Sr as an additive and found that Sr inclusion alters the host particle morphology and crystal structure. We report effects of such modifications on light scattering coefficient, brightness, opacity, tensile strength, bulk, and porosity of paper, both before and after calendering. Our results suggest beneficial optical properties, as well as combination of light scattering with strength properties, especially in the case of Sr modified filler. Zn modified fillers opened the sheet structure, while Sr structuring closed the sheets. Calendering resulted in reduced bulk with all fillers, while optical properties were maintained with the Sr modified PCC, but reduced benefit was observed in the combination of light scattering and strength. Calendering conditions should therefore be optimized for these fillers. A higher modification degree of the fillers should also be considered to achieve a more significant refractive index contrast.

Abstract:

We conducted a series of trials in a commercial-scale pulp mill producing fully bleached birch hardwood kraft pulp to study the effects of impregnation time. Retention time in an impregnation vessel was altered between 5 min and 60 min. Cooking kappa number target and brightness targets were held constant and the rest of the fiber line was operated according to normal practices. After analyzing collected pulp samples to monitor changes in characteristics and papermaking properties, we found that impregnation time has a significant effect on the consumption of effective alkali in the impregnation stage, but the total alkali consumption was not affected when a cooking kappa number was held constant. Reduced impregnation time required higher cooking temperatures to reach the kappa number target. Shorter impregnation times clearly increased the amount of rejects. Viscosity, carbohydrate composition, and fiber saturation point were not significantly influenced by the impregnation time, but some fiber damage occurred with longer impregnation times. The tensile strength and tensile were higher with the shorter impregnation time, whereas tear strength at a given tensile index did not correlate with impregnation time. An obvious reason for the affected papermaking properties was not found.

Abstract:

Increasing concerns for future fiber supplies in pulp and paper industries has shifted interest in nonwood sources from agriculture residues and aquatic plants. Aquatic plants with short growth cycles, in abundance, and with low lignin are a potential fiber source. Five aquatic plant species,Cyperus digitatus, Cyperus halpan, Cyperus rotundus, Scirpus grossus, andTypha angustifolia, were examined for fiber dimensions and chemical composition (cellulose, lignin) and compared with other nonwood plants. All aquatic plants possessed short (length, 0.71–0.83 mm) and thin (diameter, 9.13–12.11 µm) fibers, narrow lumen (diameter, 4.32–7.30 µm), and thin cell wall (thickness, 2.25–2.83 µm) compared with most other nonwood plants. Slenderness ratio ranged from 73.77 to 89.34 withTypha angustifoliahaving the highest ratio. Except forScirpus grossus, the flexibility coefficient ranged from 52.91 to 58.08.Scirpus grossushas low Runkel ratio, 0.84 ± 0.17. Fiber characteristics, short and thin fibers, Slenderness ratio >60, flexibility coefficient within 50–75, and Runkel ratio <1, are suitable for papermaking. Cellulose content ofCyperus rotundus(42.58 ± 1.32%),Scirpus grossus(36.21 ± 2.81%), andTypha angustifolia(44.05 ± 0.49%) >34% is suitable for pulp and papermaking. Lignin content in aquatic plants in the present study ranged 9.54–20.04% and below the wood lignin content of <23–30% encountered in pulp and papermaking. Handmade paper sheets produced for paperboard, craft, and decorative purposes are with permissible tensile strength, breaking length, and low moisture content.

Abstract:

The current trend to further reuse water within paper mills has resulted in more accumulated salts, as reflected by increased conductivity values. Although conductivity measurement is widely used in paper mills, its fundamental principles and interpretation are not often fully understood. This keeps papermakers from reaching the full benefits of using conductivity measurements to help manage the wet end chemistry of paper or board machines. High and variable conductivity affects the intrinsic properties of pulps, the performance of chemical additives, and the interaction between them. This paper reviews principles of conductivity; its measurement; its effect on important aspects of papermaking operations, such as retention, drainage, sizing, strength development and deposit control; and the fundamentals behind the effects of conductivity on the papermaking process. Specific mill examples are also provided. Potential solutions for operating a mill under high and variable conductivity conditions are discussed.

Abstract:

As opposed to effluents from chemical pulp production, very little is known about the endocrine potential of papermaking effluents. To evaluate the endocrine potential of biologically treated effluents from the main grades produced in Germany (fine, graphic and packaging papers), 16 samples were studied by means of the Recombinant Yeast Estrogen Assay (R-YEA). 10 samples were tested positive; seven of them were effluents from recovered paper processing mills. Possible sources of endocrine disruptors in addition to wood components include papermaking chemicals, paper converting chemicals, if recovered paper is used, and/or detrimental substances introduced by impurities in these chemicals. Six of the above samples were subjected to individual substance analyses to detect endocrinologically active or potentially endocrinologically active substances. Even though phthalate compounds were detected in concentrations between 0.46 and 2.36 μg/L, only two of the six samples were tested positive in the R-YEA, because the test fails to adequately detect this compound's class. Despite this drawback, the R-YEA will be used for further studies because of the great variety of potential endocrine substances present in paper mill effluents. In particular, mechanical and recycled fibre pulps as well as the constituents of chemical additives must be investigated in more detail.

Abstract:

This paper deals with cationic modified cellulose fibrils obtained by reacting the cellulose fibrils with 2,3-epoxypropyltrimethylammonium chloride (EPTMAC). The physical and chemical properties of unmodified cellulose fibrils (UMCF) and cationic modified cellulose fibrils (CMCF) were characterized by SEM, FTIR, degree of substitution, colloid titration, zeta potential, and thermogravimetric analysis. The experimental results showed that, after cationization, surface charge density and zeta potential reversed, thermal stability decreased, and new functional groups appeared, while the surface morphology did not show much difference from the UMCF. With the addition of three kinds of additives (UMCF, CMCF, and cationic starch (CS)) to BCTMP, the addition of UMCF and CMCF had little effect on zeta potential, while the addition of CS changed zeta potential obviously. With the increasing of additive amount, the bulk of paper sheets added CMCF did not change obviously, while the bulk of paper sheets added UMCF and CS decreased rapidly. With regard to physical strength, all the three kinds of additives could improve the tensile index and tear index; the tensile index of paper sheets added CS was higher than that of added UMCF and CMCF, while the tear index of paper sheets added CMCF was the highest among the three additives.

Abstract:

Pulp and paper production from wood material as their main resources have a total capacity about more than one million tons per year. Malaysia has a high scale of deforestation based on the main resource for pulp and paper-based industry. Malaysia as its rate is accelerating faster than any other tropical countries in the world. This problem also affects the economic losses of some countries that face deforestation. To overcome this, Napier grass as a substitute material from non-wood material had been choose for pulp and papermaking industry. This study through the full fibre analysis and morphological characterization, pulpability at kappa number via soda-AQ pulping and the characteristic. These conclude that Napier grass had a high percentage of pulp yields; with a low screening rejects; good mechanical properties by TAPPI method. Thus, Napier grass has a potential to be substitute material for becoming waste-wealth product especially for Malaysia’s pulp and papermaking industry.

Abstract:

Every year, significant amounts of date palm rachises are accumulated in Tunisia. The rational valorisation of this renewable resource is therefore imperative, in order to fulfil the sustainability approach. In this context, this work aims to study the potential use of date palm rachises as a raw material for papermaking and to compare it with other sources of lignocellulosic fibres, such as wood, non-wood species, and agricultural wastes. For this purpose, soda-anthraquinone pulping of date palm rachis was performed giving rise to a yield of 45% (w/w). This value is similar to that obtained by pulping non-wood materials and is higher than that corresponding to the pulping of agricultural residues. The resulting pulps were subsequently refined using a PFI mill refiner at 0, 500, 1500, and 3000 revolutions, screened through a 0.15 mm mesh size sieve and used to produce conventional handsheets. Both pulps and papers were fully characterized in terms of morphological, chemical and physical properties, according to commonly used standards. The physical properties of the prepared handsheets were very similar to those displayed by other papers made of common lignocellulosic fibres. Furthermore, the pulps exhibited a good drainability together with excellent mechanical properties of the ensuing papers. For these reasons, date palm rachises could be considered as a potential source of fibres for papermaking applications.

Abstract:

The aim of this study was to investigate a potential biorefinery process to realize the high utilization of Camellia oleifera shell (COS), which is an agricultural by-product mainly composed of cellulose, hemicellulose, and lignin. Before treatment by steam explosion, the COS was impregnated with water, 3.0 wt% NaOH solution, or 3.0 wt% H2SO4 solution. The morphological structure and chemical composition of the steam-exploded COS pulp were investigated. The results indicated that the impregnation treatments increased the cellulose content of the steam-exploded COS pulp and decreased the hemicellulose and lignin content. The morphology of steam-exploded COS fiber was short, coarse and stiff. Hydrophobic and colorful handsheets were fabricated by mixing proportional bleached softwood fiber. This study demonstrated that COS was a potential material for the papermaking industry, and the combination of water impregnation and steam explosion treatment for COS was a good pulp process.

Abstract:

Abstract The main objective of the current study was to demonstrate that it is possible to enhance strength properties of sheets from spruce HT-CTMP and CTMP furnishes up to the same level as is common on sheets from softwood kraft pulps by changing conditions in papermaking. To achieve that, sheets of spruce HT-CTMP and CTMP were consolidated at densities close to that of the reference bleach kraft pulp by pressing at press nip temperatures well above the tack and softening temperatures of lignin. On sheets from spruce CTMP (CSF 420 ml), where the fibers were surface treated with cationic starch, it was possible to reach tensile index at the same level as on sheets from the untreated reference kraft pulp. The compression strength (SCT) of CTMP and HT-CTMP sheets, which were achieved at the highest press nip temperature (200 °C) in the study, was equal to or higher than that of the reference kraft pulp sheets. The results show that there is a great yet unexploited potential in papermaking from spruce HT-CTMP and CTMP furnishes, which could be utilized in manufacturing of products where very high requirements upon strength is demanded.

Abstract:

Based on publications related to the use of micro- and nanofibrillated cellulose (MNFC) in papermaking applications, three sets of parameters (intrinsic and extrinsic variables, furnish composition, and degree of dispersion) were proposed. This holistic approach intends to facilitate understanding and manipulation of the main factors describing the colloidal behavior in systems comprising of MNFC, pulp fibers, and additives, which directly impact paper product performance. A preliminary techno-economic assessment showed that cost reductions driven by the addition of MNFC in paper furnishes could be as high as USD 149 per ton of fiber (up to 20% fiber reduction without adverse effects on paper’s strength) depending on the cost of papermaking fibers. It was also determined that better performance in terms of strength development associated with a higher degree of MNFC fibrillation offset its high manufacturing cost. However, there is a limit from which additional fibrillation does not seem to contribute to further strength gains that can justify the increasing production cost. Further research is needed regarding raw materials, degree of fibrillation, and combination with polyelectrolytes to further explore the potential of MNFC for the reduction of weight of paper products.

Abstract:

In the papermaking industry (reconstituted tobacco), a large number of tobacco stems, dust, and fines are discharged in the wastewater. This high salinity wastewater rich in ionic constituents and nicotine is difficult to be degraded by conventional biological treatment and is a serious threat that needs to be overcome. Electrodialysis (ED) has proved a feasible technique to remove the inorganic components in the papermaking wastewater. However, the fouling in ion exchange membranes causes deterioration of membranes, which causes a decrease in the flux and an increase in the electrical resistance of the membranes. In this study, the fouling potential of the membranes was analyzed by comparing the properties of the pristine and fouled ion exchange membranes. The physical and chemical properties of the ion exchange membranes were investigated in terms of electrical resistance, water content, and ion exchange capacity, as well as studied by infrared spectroscopy (IR) spectra, scanning electron microscopy (SEM), and energy dispersive spectroscopy (EDS) analyses. The results indicated that the membrane fouling is caused by two different mechanisms. For the anion exchange membranes, the fouling is mainly caused by the charged organic anions. For the cation exchange membrane, the fouling is caused by minerals such as Ca2+ and Mg2+. These metal ions reacted with OH− ions generated by water dissociation and precipitated on the membrane surface. The chemical cleaning with alkaline and acid could mitigate the fouling potential of the ion exchange membranes.

Modified cassava starch is widely used in a range of applications such as food and beverage, papermaking, textiles, chemicals, constructions, adhesives, and pharmaceuticals. Hence, there is a massive demand for modified cassava starch in Indonesia. Nowadays, in the agricultural sector, our production capacity is only 1% of the total demand and this means that there are not many modified starch plantations in Indonesia. The aim of this research is to identify the external and internal factors that influence the foreign direct investment potential of modified cassava starch in Indonesia.

Abstract:

Calcium carbonate provides good optical properties to graphic paper and is relatively inexpensive. Therefore, the use of calcium carbonate for the production of paper has steadily increased. But the high amount of calcium carbonate in paper for recycling and the closure of water circuits leads to a high concentration of calcium ions in the process water of paper mills. The consequence can be undesired precipitation and deposition of calcium carbonate in machines and plant components of the mills. Enhanced knowledge about the precipitation potential of calcium carbonate is needed to avoid or reduce undesired precipitation and deposition. The potential can be described using the Langelier saturation index (LSI). Our investigations showed that a deposition of calcium carbonate only happens if the LSI value is higher than 0.5. An LSI value above 0.5 often exists in process water that is treated in a biological effluent treatment plant. Reasons for such values are the increase in hydrogen carbonate concentration (m-alkalinity) by carbon dioxide production and the increase of the pH value by reduction of fatty acids. With the knowledge about the precipitation potential of calcium carbonate in a process water line, suitable measures could be implemented.

Abstract:

During the last few years increasing attention has been paid to the exploitation of hemicelluloses as biopolymer resources because they are available in very large amounts in organic wasters from renewable forest and agricultural biomass. The efficient method to prepare the cationic biopolymers based on xylan-rich hemicelluloses from agricultural biomass has been developed in this paper. These biopolymers with cationic functional groups, having many good properties such as solubility, bio-degradation, cationic or ampholytic polymers, were synthesized by the chemical modification of sugarcane bagasse xylan-rich hemicelluloses with CHMAC and preferably with ETA in different media. These biopolymers based on xylan-rich hemicelluloses with the degree of substitution (DS) up to 0.55 could be obtained by varying the molar ratio of ETA or CHMAC to anhydroxylose units in hemicelluloses from 0.5 to 3.0. 13C NMR confirmed that cationic groups were grafted onto the backbone of hemicelluloses. In addition, their applications in papermaking as dry strengthen agent were investigated. It was found that these biopolymers could obviously improve the physical properties of hand sheets formed from old corrugated container pulp fibres. These results mentioned above highlight the remarkable potential for using the hemicelluloses-based biopolymers as wet end additives in papermaking.

Abstract:

Paper is an excellent medium of expression and knowledge preservation and communication because of its writing, printing, and packaging abilities. It is a thin sheet or web-like structure made by a dilute suspension of cellulosic fibres. Handmade papermaking technology was mass accepted and considered a precious commodity before development of an industrialised wood- pulp based paper industry. This modern papermaking practice harms the environment as it uses enhanced natural resources (ample amount of water, trees as a primary source for wood pulp) and generates pollution due to release of harsh chemicals. This paper reviews the history and process of handmade paper manufacturing from past to present. Along with that, all the pillars of sustainability (environmental, economic, and social) in relation to the handmade paper industry are deep rooted since ancient times and very much relevant for the present era of sustainable development. Various kinds of cellulosic raw materials from plants (Paper mulberry, Kazo, Gampy, hemp, bamboo, banana, etc.) and other used materials (old rags, ropes, nets, newspapers etc.) with the chemical-free production process and products make this industry eco-friendly. Craft based, small scale and labour-intensive guild art gives it social strength; whereas an infinite product range having functional and decorative uses, as well as strong export potential of the industry gives it an economic strength. Due to the present need of sustainable production, waste minimisation, and circular economy, the handmade paper seems to very potential industry to recycle various kind of waste like weedy battles, textiles, tetra packs, currency, plastic etc. This paper is an attempt to review the journey of handmade papers, its recycling potential, various production processes, products, advantages and disadvantages of the industry from past to present.

New methods for liberating these materials, including nanodimensional cellulose fibrils, macromolecules and nanominerals will be needed in order to use the techniques developed for other nanomaterials as platforms for creating new wood-based materials and products. Research findings showed promising results in application of nanotechnology at different aspects of papermaking. Electrospinning; chemical treatment followed by mechanical techniques; or mechanical isolation methods were applied by different research groups to prepare cellulose nanofibres.

Although jack pine (Pinusbanksiana Lamb.), which represents 20% of the total softwood volume, is one of the most abundant commercial softwood species in Canada, its rate of utilization in pulping is surprisingly low. This paper reviews the literature concerning the physical and chemical properties as well as the pulping characteristics of this species by mechanical, thermomechanical, chemithermomechanical, chemimechanical, and chemical processes to better understand its potential use in papermaking. The objective is to identify the problems related to the use of jack pine so that solutions might be sought to promote its usage. Some recommendations are put forth concerning future research.

Abstract:

Among bio-based reinforcement additives for paper existing on the market, microfibrillated cellulose (MFC) turned out to be a promising material, showing outstanding potential in composites science. Its relevance in papermaking as a new family of paper components was suggested more recently. There remains a number of constraints limiting the promotion of their use in papermaking, mostly related to their high cost and effect on dewatering resistance. Also, contrasting results reported in the literature suggest that the effect of fibrillation rate and quantity of such cellulosic additives in a furnish on the technological paper properties needs further research. The purpose of this study is to produce and characterize different MFC-like fine fibrous materials of varying particle size and degree of fibrillation from the same batch of pulp through mechanical treatment or fractionation. The effect of the thus obtained fine fibrous materials on paper properties is evaluated with respect to their concentration within a fiber furnish. We compared: (i) a mixture of primary and secondary fines isolated from the pulp by means of a purpose-built laboratory pressure screen; (ii) MFC-like fine fibrous materials of increasingly fibrillar character obtained by refining and subsequent steps of high-pressure homogenization. The morphology of the different materials was first characterized using flow cell based and microscopic techniques. The thus obtained materials were then applied in handsheet forming in blends of different proportions to evaluate their influence on paper properties. The results of these experiments indicate that all these products lead to a substantial decrease in air permeability and to improved mechanical properties already at low concentration, independent of the type and morphological character of the added fine cellulosic material. At higher addition rates, only highly fibrillated materials allowed a further considerable increase in tensile and z-strength. These observations should help to allow a more targeted application of this new generation of materials in papermaking, depending on the desired application.

Analysis of the potential genetic variation in quaking aspen (Populus tremuloides Michx.) wood extractives was performed by sampling nine natural clones at breast height. Significant clonal differences were found not only in the levels of total acetone extractives but also in the levels of sterolstriterpenes, steryl esterswaxes, and triglycerides, all of which are known to contribute to pitch formation in pulping and papermaking. In addition, extractive compounds known to elicit toxic effects in aquatic organisms showed statistically significant differences between natural aspen clones. In some cases (e.g., flavonoids), these compounds formed a part of the defense system in the living tree and, thus, were affected in part by the presence of decayed wood.

Abstract:

Commodification of Traditional Knowledge (TK) has been posited as a possible, although contested, alternative for the conservation of indigenous resources. Here we examine the case of the Chinese Naxi minority, with particular reference to the practice of sacred “Dongba” papermaking. The commodification of TK is a complex process with many pitfalls and trade-offs between the environment, economy, and social empowerment. In the process of commodification, consumers have arisen as an important force in environmental politics. To date, little is known about the way domestic tourists, the main consumer base of indigenous products, perceive Dongba paper. In this context, we examined their knowledge of Naxi culture, their willingness to pay for sustainably produced paper, and their perceptions of the product’s authenticity. This socio-economic study is based on a survey (n = 415) in rural Southwest China. We found a significant potential to market Dongba paper as a sustainable indigenous product. Although knowledge about Naxi culture was circumscribed (3% could identify the plant used for papermaking), the majority of respondents (55%) was willing to pay for TK protection. Respondents also preferred third-party labelling. We posit that TK products could be seen as credence goods, necessitating certification to ensure product authenticity and establish consumer trust. Markedly, the survey also found that attitudes as to who should provide third-party assurance are contradictory. The Chinese government was preferred as the strongest assurance of genuineness, but paradoxically, commanded the least trust in its ability to manage and fund the conservation of TK.

Several Eucalyptus cultivars has been introduced and cultivated for millions of hectares afforestation in subtropical China, whose woods were mainly used in papermaking industry and whose water essential oils were used mainly in aroma and medical industry. However, the potential biomedical components of organic essential oils were still uncovered. In order to reveal constituent characteristic and biomedical potentials of organic essential oils from leaves of four Eucalyptus cultivars (E. camaldulensis,E. tereticornis,E. citriodoraandE. dunnii) in China, their components were efficiently extracted by improved solvents extracting condition, which were identified by optimal gas chromatography / mass spectrometry (GC/MS). The functional analytical results suggested that these four Eucalyptus cultivars possess large numbers of common components, especially including Eucalyptol, 1-Eicosanol, (+)-Longifolene, (+)-Aromadendrene, Phytol and (-)-Alloaromadendrene, which are good materials for aroma and biomedical industry. The contents of common components of four Eucalyptus cultivars are as high as 68.97%, 81.81%, 60.64% and 64.29%, respectively. Moreover, each Eucalyptus organic essential oil also has specific components with potentials in aroma industry or biomedical industry.
