Plant factory lumbering Products
Next Previous Return to Start. Lumbering has four phases: logging , driving , manufacturing , and transport. The details varied depending on whether a homesteader was carving a farm out of a forest, an independent logger was felling and selling logs to a mill, a commercial mill handled the entire process from logging through sales. Early on, logging was generally limited to the winter months, mid-November through mid-March weather permitting, when horses or oxen could drag felled and trimmed logs and sleighs of logs on snow-covered ground to collection points at the edge of a nearby river, lake, or later a railway stop.VIDEO ON THE TOPIC: Collum's Lumber Products, LLC - Sawmill Tour

Forestry and Forest Products
One of the basic materials of human civilization, wood still plays a central role in 21st-century life. It's used in home construction and furnishing, in transportation, and in the manufacturing of countless consumer products.
It's also used, in the form of wood pulp a fibrous material made from processed wood chips , to produce paper, paper products, and fabric. And in large parts of the world, particularly in Africa, wood remains an important source of fuel for cooking and heating. Unfortunately, wood is also a major driver of deforestation.
But because wood is used in so many different ways, the relationship between wood products and deforestation is complicated. Some wood products, such as fuelwood and timber, largely drive forest degradation—which is often the precursor to deforestation. Others, such as pulp and paper, may come from deforestation in Southeast Asia or from plantation forests around the world.
And while some wood products can be traced back to unsustainable sources, well-managed wood is a renewable resource. Much of the wood we use comes from plantation forests, but a significant portion of it is extracted from natural forests.
About a third of wood extracted from natural forests worldwide is used for timber products. In Southeast Asia, particularly Indonesia, timber harvesting is a direct driver of forest clearance ; after forests are cleared for timber, these areas may be converted into wood plantations. But for the most part, the use of wood for timber or fuel drives forest degradation, in which forests are thinned and some carbon is lost, as opposed to deforestation, where the entire forested landscape is lost.
Though much more common than deforestation , forest degradation has a smaller overall global warming impact. Timber production drives forest degradation through selective logging, where the more valuable tree species are removed from the forest. Yet selective logging can be more damaging than it sounds. It can have an outsized impact on the surrounding ecosystem: the selective logging of one tree can damage 10 to 20 surrounding trees.
Selective logging also makes a forest more vulnerable to fire and other threats, and may change its suitability as habitat for some species. Selective logging can also be a first step toward deforestation: degraded forests are more likely than intact forests to be targeted for conversion to other uses , such as palm oil in Southeast Asia or soy or beef in Latin America. While fuelwood constitutes more than half of the wood extracted from natural forests, it mostly drives degradation rather than deforestation—except in the case of charcoal, which represents a small fraction of the total.
Like soy , beef , and timber and unlike palm oil , paper is not exclusively produced in the tropics. In fact, the three biggest paper-producing countries the United States, Canada, and China are all in temperate regions. But tropical countries have become an important source of pulp and paper , thanks in large part to their year-round growing season and lower business costs.
Brazil and Indonesia are the largest pulp-producing countries in the tropics, but they play very different roles when it comes to deforestation. In Brazil, paper plantations tend to occupy former pasture land , so they have relatively little direct deforestation impact. In Indonesia, on the other hand, the drive for wood pulp has led to the destruction of forests to make way for new plantations of "fast wood" such as acacia.
This is particularly harmful because about a quarter of fastwood plantations were cleared on carbon-rich peat soils , adding significantly to global warming pollution. When they replace pasture or agriculture, they can support increased carbon storage and biodiversity —though they fall well short of natural forests on both counts. And plantations are more efficient than natural forests, producing 3 to 10 times more usable wood.
These certifications provide assurance to consumers that the wood used in their purchases meets ecological, economic and social standards—though as of , only 2 percent of tropical forests were certified. In addition, a number of countries—including the United States—have passed laws prohibiting the sale of any plant obtained illegally.
While fuelwood consumption is actually projected to decrease over coming decades, timber and pulp consumption will continue to climb. To prevent this rising demand from contributing to global warming and biodiversity loss, we need to ensure that wood production is not linked to deforestation or forest degradation. Plantation forest area for both timber and paper has been increasing worldwide, and now accounts for 7 percent of the world's total forested area —over million hectares—with more than 3 million hectares added each year.
By , all types of paper consumption are predicted to at least double, and in some cases almost triple. The use of recycled paper, non-wood fibers, and waste wood in paper production can allow for meeting the world's paper product needs while using fewer trees.
The future. While fuelwood consumption is expected to plummet over the next half-century, demand for industrial roundwood which includes both timber and pulp is expected to increase steadily. Increasing demand for pulp will accelerate around mid-century, according to projections. Share Twitter Facebook LinkedIn. Related resources Explainer.

12 Uses of Wood Product in Everyday Items
The decision to build a plywood plant was made in April In December the plywood plant was put into operation. The new plant was designed to have a capacity of 50 thousand cubic meters of plywood. The technology of plywood production was being mastered, plant workers acquired certain skills, and in the real output of plywood surpassed the border of 30 thousand cubic meters per year. At the same time, a new kind of plywood was created - combined with internal layers of coniferous wood. This was recognized as an invention, and it was awarded with a bronze medal of the Exhibition of Economic Achievements. In the Arkhangelsk plywood plant was the first one in our country to produce so-called hard-combustible slabs. The second stage in the development of the plywood plant came in with the release of the Law on Cooperation.

Throughout Canada, it is widely known that trees are vital to the environment. Trees are also highly necessary for human existence due to the absorption of carbon dioxide and other gases, the production of oxygen, and the food, fuel and habitat they offer. However, trees also add ease and luxury to human lives as cellulose powdered wood pulp , and other tree components, are often added to everyday products, from tasty snacks to art supplies.

The Lumbering Process
Descriptions of manufacturing processes 1. This analysis had to identify the amount, type and quality of energy required so as to identify possible energy savings compatible to the respective cost-benefit analysis. The following process descriptions of the manufacture of sawn timber, plywood and particleboard are of a general nature and should provide the reader with a broad outline of the production processes involved in the mechanical wood-based industry and the role in which energy plays a part. Sawmilling is a less sophisticated activity of the mechanical forest industries. It implies a certain number of operations from handling and transportation of logs to timber drying, sorting and classification which require different types of energy. Whereas in developing countries most of the processes are highly mechanized and the energy requirements are met basically with the generation of a few kW to drive the main saws.
Demand for wood products such as paper, furniture and construction materials is a major cause of damage to tropical forests—and that demand is projected to increase over the next half-century. The good news is that there are ways to satisfy that demand sustainably. The UCS report Planting for the Future combines economic modeling with ecological theory and data to evaluate the impact of increased demand on tropical forests, and shows how innovative management practices, reinforced by effective policy and consumer awareness, can meet projected wood product needs while also conserving forests. Wood is a ubiquitous part of everyday life.
