Woodchipping is the act and industry of chipping wood for pulp. Timber is converted to woodchips and sold, primarily, for paper manufacture. In Australia, woodchips are produced by clearcutting or thinning of native forests or plantations. In other parts of the world, forestry practices such as short rotation coppice are the usual methods adopted.[ citation needed ]
Uses of wood chips includes the manufacture of particle board (or "chip board") and other engineered woods, mulch and fuel.
Historically, the primary sources of wood chips in Australia have been the extensive Eucalyptus hardwood forests found throughout temperate areas of the country. In more recent times, a significant proportion comes from managed hardwood and softwood plantations.[ citation needed ]
During the late 1960s and 1970s, the high demand for paper and the relatively low cost and availability of the native forests made the establishment of a woodchipping industry a viable proposition. Conversely, the establishment of a woodchipping industry made it economically feasible to clearfell areas of mixed or substandard forest that could not otherwise have been felled. Clearfelling is a controversial forest practice in Australia, and opponents argue that the woodchipping industry is culpable for its continuation.[ citation needed ]
Woodchips are converted into a fibre that can be made into various grades of paper or rayon for the textile industry. Most processing and value adding takes place outside of Australia. [1] The Australian economy benefits directly from a low-cost and high-volume export commodity. [2]
Wood chips, as a byproduct of the timber industry, have been used in many ways for centuries, for example as a material for the production of wallpaper or as a disposable floor covering in butchers shop or drinking houses. Wood pulp is the primary market for the woodchipping industry in Australia.[ citation needed ]
The practice, known as woodchipping, was to make use of most of the woody material in a tree to produce wood chips. This was then converted into paper, hardwood pulp is mainly used for printing paper and softwood pulp is added for good quality. [3] An energy-intensive process, it also involved the use of bleaches and other toxic chemicals. This stage of the process, known as Kraft pulping, was primarily performed in Japan and elsewhere. High demand for paper products had purpose-built bulk carriers increase the export of woodchips from Australia to Japan.[ citation needed ]
The separation of the chipping stage and the pulping and paper mills required the supply of energy usually sourced from byproducts of the process. Additional energy expenditure is found in the shipping of raw materials and export of the finished product.[ citation needed ]
The introduction of the wood chip industry to Western Australia in the 1960s initially attracted less opposition than it did in the eastern states. At first it was seen as an opportunity for the economic development of the south west; it was not until the 1970s that an environmental movement against it began to emerge[ according to whom? ]. The volatility of the issue became apparent in 1976 when two activists carried out the Bunbury woodchip bombing, a failed attempt to disable woodchip exporting facilities for 18 months. [4] Following decades of campaigning by environmental groups and others commercial forestry within native forests, including for woodchipping, was ended in Western Australia and eastern Victoria in 2024.

The Wilderness Society has revealed today that Forestry Tasmania is planning to clearfell and woodchip areas of pure rainforest in north-west Tasmania and then convert the cleared areas to plantations.
Newspoll - December 1994 - To the Question "Next a question about native forests. Do you personally approve or disapprove of trees from Australian's native forests being fell and exported as woodchips to Japan? 80.3% of Australians disapproved, 11.7% approved, 8.0% undecided.
Mr Tuckey was responding to reports in the Launceston Examiner suggesting the phasing out of woodchipping in Tasmania. Press reports in the United States are quoting well known green activists as saying that the US fires, including forest and property destruction, are the result of past forest management policies that prevented harvesting. This has created 'cadaverous' forests overpopulated with sick, dead and skinny trees — the perfect fuel for a wildfire.
The export of woodchips from Australian native forests over the last few decades has been one of Australia's greatest economic and environmental disasters. Heavily subsidised and poorly managed, wood chipping has continued despite the trend amongst Australia's policy makers towards the rhetoric of economic rationalism. Even though only those with a vested interest could argue for wood chipping on economic grounds, it has managed to gain the strong support of both Labour and Liberal/National Parties. Yet despite these contradictions and the enormous passion the wood chipping debate generates, historians have tended to ignore this issue. John Dargavel's excellent history of Australian forestry goes a long way to filling this gap. Dr Warwick Frost lectures in the School of Economics, La Trobe University.
Lumber is wood that has been processed into uniform and useful sizes, including beams and planks or boards. Lumber is mainly used for construction framing, as well as finishing. Lumber has many uses beyond home building. Lumber is sometimes referred to as timber in the United Kingdom, Europe, Australia, and New Zealand, while in other parts of the world the term timber refers specifically to unprocessed wood fiber, such as cut logs or standing trees that have yet to be cut.
Logging is the process of cutting, processing, and moving trees to a location for transport. It may include skidding, on-site processing, and loading of trees or logs onto trucks or skeleton cars. In forestry, the term logging is sometimes used narrowly to describe the logistics of moving wood from the stump to somewhere outside the forest, usually a sawmill or a lumber yard. In common usage, however, the term may cover a range of forestry or silviculture activities.
Pulp is a lignocellulosic fibrous material prepared by chemically or mechanically separating cellulose fibers from wood, fiber crops, waste paper, or rags. Mixed with water and other chemical or plant-based additives, pulp is the major raw material used in papermaking and the industrial production of other paper products.
Softwood is wood from gymnosperm trees such as conifers. The term is opposed to hardwood, which is the wood from angiosperm trees. The main differences between hardwoods and softwoods is that the structure of hardwoods lack resin canals, whereas softwoods lack pores.
Pulpwood is timber with the principal use of making wood pulp for paper production.
Gunns Limited was a major forestry enterprise located in Tasmania, Australia. It had operations in forest management, woodchipping, sawmilling and veneer production. The company was placed into liquidation in March 2013.

The Campaign to Save Native Forests (W.A.) (CSNF) was the name of a grassroots organisation which grew from a campaign started in Perth, Western Australia, in 1975, as a response to the development of a woodchipping industry in the south-west jarrah and karri forests of Western Australia. The Manjimup woodchip project aroused significant levels of protest in Perth and the South West region out of public concern that inadequate measures had been made for conservation alongside exploitation of the south west hardwood forests.
The W.A. Chip & Pulp Company was founded in 1969 to export woodchips from sustainable bluegum plantations after the Government of Western Australia granted a Bunnings led consortium rights to establish a woodchip project in Manjimup. In August 2000, the business was sold to Marubeni.
Forestry Tasmania trades as Sustainable Timber Tasmania but is still legally called Forestry Tasmania. It is a government business enterprise wholly owned by the Government of Tasmania, Australia. It is responsible for the management of public production forest in Tasmania, which is about 800,000 hectares of crown land that is classified as 'permanent timber production zone'.
A forest product is any material derived from forestry for direct consumption or commercial use, such as lumber, paper, or fodder for livestock. Wood, by far the dominant product of forests, is used for many purposes, such as wood fuel or the finished structural materials used for the construction of buildings, or as a raw material, in the form of wood pulp, that is used in the production of paper. All other non-wood products derived from forest resources, comprising a broad variety of other forest products, are collectively described as non-timber forest products (NTFP). Non-timber forest products are viewed to have fewer negative effects on forest ecosystem when providing income sources for local community.
The Russian forestry industry is a set of Russian industries related to wood harvesting and processing. As one of the oldest sectors in the country's economy, Russia's timber industry continues to bring in about $20 billion per year. Russia has more than a fifth of the world's forests, making it the largest forest country in the world. According to data for 2015, the total forest area has exceeded 885 million hectares, representing 45% of the total area of the country. The stock of wood in the area was 82 billion cubic meters. However in 2023 academics complained that not enough information had been published.
Woodchips are small- to medium-sized pieces of wood formed by cutting or chipping larger pieces of wood such as trees, branches, logging residues, stumps, roots, and wood waste.
Australia has many forests of importance due to significant features, despite being one of the driest continents. As of 2009, Australia has approximately 147 million hectares of native forest, which represents about 19% of Australia's land area. The majority of Australia's trees are hardwoods, typically eucalypts, rather than softwoods like pine. While softwoods dominate some native forests, their total area is judged insufficient to constitute a major forest type in Australia's National Forest Inventory. The Forests Australia website provides up-to-date information on Australia's forests. Detailed information on Australia's forests is available from Australia's State of the Forests Reports that are published every five years.
Woodchipping in New Zealand is one of the sectors of the forestry industry and it attracted controversy in the 1990s when native trees were used as a source for the chipping.
Forestry in New Zealand has a history starting with European settlement in the 19th century and is now an industry worth seven percent of annual revenue. Much of the original native forest cover was burnt off and logged, however forests have been extensively planted, predominantly with fast-growing cultivars of the Monterey Pine. Wood chips, whole logs, lumber and paper products are exported from New Zealand.
Lumber and wood products, including timber for framing, plywood, and woodworking, are created in the wood industry from the trunks and branches of trees through several processes, commencing with the selection of appropriate logging sites and concluding with the milling and treatment processes of the harvested material. In order to determine which logging sites and milling sites are responsibly producing environmental, social and economic benefits, they must be certified under the Forests For All Forever (FCS) Certification that ensures these qualities.
The Farm Forestry Toolbox is a collection of computer programs, referred to as 'Tools', intended to be used by farm forest owners and managers to aid decision making. The Toolbox includes a set of simple 'Hand Tools'; conversion of measurements and map co-ordinates; measuring the volume of stacked logs, slope, basal area; and a survey tool. A second set of more complex tools or 'Power Tools'; can be used to estimate site productivity, volume and value of wood grown for individual trees, at the coupe or stand level and forest estate level.
The wood industry or timber industry is the industry concerned with forestry, logging, timber trade, and the production of primary forest products and wood products and secondary products like wood pulp for the pulp and paper industry. Some of the largest producers are also among the biggest owners of timberland. The wood industry has historically been and continues to be an important sector in many economies.
The Victorian Plantations Corporation (VPC) of Victoria, Australia, was established under the State Owned Enterprises Act in May 1993, and by June 1993 was declared a State Business Corporation.
It will also help cut Australia's bill for imports of wood and paper products. Imports of these products currently exceed our exports by $2 billion a year.
