This study has evaluated the factors affecting the utilization of alternative fiber resources and efforts have also been made
to outline the possible alternative fiber resources available in the country. Since 1989, paper consumption has exceeded production.
Imports of industrial paper have increased and the future of newsprint export is dark. The government sector pulp and paper
mills are highly dependent on forest based fiber resources and private sector paper and board mills depend on imported pulps.
Uneven distribution of fiber resources has limited the raw material availability of the pulp and paper mills. Shortage of
raw materials, irregular procurements, and low installed capacity are the main reasons for low paper production. On the other
hand, paper demand will increase tremendously in the near future. But the present raw material availability is not sufficient
to cope with the future demand for attaining self sufficiency in paper production. Therefore, immediate action is necessary
for utilizing alternative fiber resources. Rangpur region has abundant lower grade jute. Jute cutting is available in Narayangonj
area. Available bagasse supply is expected in the northwest regions after the end of this century. These resources are more
than enough for supplementing the shortage of present raw materials during the 1997–2006 period.

Abstract A partial equilibrium forest sector model which is augmented to include bioenergy was applied to project the use of bioenergy based on forest fuels and forest industry by-products in Norway for three different scenarios of the future prices of electricity and oil. The impacts on forestry and forest industries of the different energy price scenarios were also studied. The advantage of the suggested methodology is that it allows for assessments of the economic potential of bioenergy, taking into account the competition for raw materials, the specific heat demand of various regions, and interregional and international trade. Bioenergy will, according to this study, be fairly competitive in some market segments with the current price levels of electricity and oil, and only a minor increase (decrease) in energy (roundwood) prices would release substantially increased bioenergy production levels. Pulpwood prices of pine and non-coniferous species are projected to increase substantially when assuming increasing energy prices. Except for particleboard mills, production levels of forest industries appeared relatively insensitive to the energy price changes. 相似文献

随着纸及纸板生产与消费数量的不断提高,我国造纸工业结构调整的发展对木材原料的需求将持续增加。我国木材市场数据显示,以原木、锯材等为代表的木材原料,以木浆、木片为代表的造纸原料进口均呈平稳增长趋势,木材市场供需矛盾突出。造纸工业竞争的核心是木材原料的争夺,而我国木材市场自有木材供给的严重不足性和进口总量的绝对依赖性特征决定了造纸工业木材原料未来仍将依靠进口。 相似文献

Abstract The changing market conditions for the Swedish sawmill industry place a focus on a better understanding of the pros and cons of value-added and forward integration strategies. The purpose of this article is to describe and explain recent value-added strategies in the Swedish sawmill industry. The study includes strategies from 13 of the 15 largest sawmill companies for the period between 2002 and 2005, describing a differentiation between value added in primary sawmill production and forward integration into secondary production. It also aims to relate some basic conditions, such as company size, company growth and corporate strategy, to value added and forward integration to profitability. The results show strong positive and significant correlations between forward integration, value added in primary production (somewhat weaker) and unit revenue, and profitability measured as return on investment. There were no strong or significant correlations between size and profitability, playing down the importance of economies of scale (among these already large companies). An interesting result is the much higher profitability of the buying sawmill companies compared with the forest corporations, stressing the importance of both a long-term strategy when investing in value-added activities and ultimately the priorities of ownership. 相似文献

运用多元统计分析的方法,研究了四川盆地西缘山地柳杉人工林的密度和直径—株数分布的规律,筛选出了影响林分密度的主导因子(林今年龄、地位指数和林分平均直径),并建立了林分密度预测模型。还根据西泽正久(1978)所提供的求解Weibull分布参数e的gamma和Cud数值表,对48块林令标准地的林木株数调查结果用Weibull分布函数进行了拟合。结果表明:有33块标准地的拟合结果经卡方检验达到极显著水牛(α=0.01),有10块标准地达显著水平(α=0.05),另有5块标准地的拟合结果则不符合weibull分布。在此基础上,对影响柳杉人上林Weibull分布函数的 b、c参数的林分结构因子进行了回归分析,并用易测林分结构因子建立了两个参数的预测模型。 通过建立上述预测模型,作者对柳杉人工林的结构和生长量进行了综合预测。经检验结果表明:本次研究所建立的预测模型达到精度要求,为森林资源预测、森林经营管理、抚育间伐提供科学依据。 相似文献

Electricity prices in Sweden will most probably double, or more, during the next 10 to 15 years as a result of the decision to discontinue nuclear power production. This will substantially change the comparative advantage of all forest‐based product industries, some to the worse, some to the better. Roundwood prices and fellings will be affected and possibly the competitive position of wood‐based energy production. This paper estimates various types of effects with a long run pulpwood market model. The effects on electricity intensive production (CTMP, newsprint, etc.) may be drastic. However, the fall in total industrial consumption and price of pulpwood will be limited. The reduction in price is not sufficient to make pulpwood economically attractive as fuel. Own‐price elasticities of electricity demand are greater than reported elsewhere. 相似文献

关于木材需求曲线修正法的讨论 总被引:2,自引:2,他引:0
木材需求曲线与森林环境需求曲线的价格需求弹性是不同的,后者远比前者大。在这种的情况下,用木材需求曲线近似代替计算森林环境价值,会严重低估森林环境价值,理论上有严重的缺陷。加上以木材价值替代全部森林非木材产品的价值,也会导致对森林环境价值的低估。这2个相同方向的差异累积后,导致木材需求曲线修正法严重低估森林环境价值。另外,木材需求曲线修正法也不能评价具体的涉及森林环境价值的项目,因此,没有实际的应用价值。 相似文献

Analysis of consumer demand for packaging suggests that: plastic packaging is a luxury good, while paper packaging is a normal good, paper packaging demand increases with the price of plastic packaging, and that demand for paper packaging is most sensitive to its own price, and to the income of consumers. In a complementary analysis of input demand in the converting paper industry it was found that the demand for each paper grade is price inelastic, capital and other materials are substitutes for paper, while labor is a complement, technical change rapidly decreases the use of unbleached kraft packaging and industrial converting, and increases the use of other grades. The demand for each paper grade, derived from the consumer demand and the factor demand functions, showed that, from 1983 to 1991, the demand for paper in packaging was influenced mainly by consumer income, and by the price of paper packaging, and less so by the price of paper itself, or by the price of plastic packaging. 相似文献

Selecting the optimum location with attention to conditions and restrictions is one of the most importantfactors in establishing a manufacturing plant. Identification of effective criteria is an important stage in the selection for the location of industrial units. In this study, an analytic hierarchy process (AHP) was applied to select the most effective criteria for the location of MDF (medium density fiberboard) industry in Mazandaran Province, Iran. A consideration in ttaining this goal is that Mazandaran is favored over other provinces because of its resources of raw lignocellulosic ma- erial required for wood and paper industries. The results indicate that the criterion of "materials and products" and the ub-criterion of "reliability of supply of raw material" are the most important factors. 相似文献

The forest-based industry has a crucial role in global sustainable development because of its unique raw material basis and increasing internationalisation. Using institutional organisation theory as a background this paper analyses corporate responsibility reporting in the world's ten largest pulp and paper companies, representing 25% of global production capacity. The studied companies have their headquarters in Japan, the Nordic countries or North America, and have very different geographical and cultural bases and variable company product portfolios ranging from wood-based products and printing papers to packaging boards and consumer goods. Both quantitative and qualitative economic, environmental and social metrics from the annual and social responsibility reports of the companies were analysed regarding institutionalised, culture-specific and company-specific characteristics. The results showed that regulated financial and environmental reporting leaves little flexibility for company-specific diversification in reporting. Only a few regional characteristics were identified, mainly in social responsibility reporting, while the reporting largely reflected a general North American–Nordic type of corporate responsibility and the globalisation trend of the studied companies. Regardless of the many challenges in the assessment of corporate responsibility, the concepts discussed in this paper are potentially useful tools for helping to achieve sustainable development in the pulp and paper industry. 相似文献
