Woodchipping is the process of turning wood into chips for pulp, primarily used in paper production. In Australia, woodchips come from either thinning managed plantations or clear-cutting natural forests. This method differs from some other parts of the world that rely on short rotation coppice forestry techniques. Woodchips are a versatile product with uses beyond paper. They can be used to create particle boards (also known as chipboards) and other engineered woods, mulch for landscaping, and even fuel.
Australia's vast eucalyptus hardwood forests, which can be found in all of the country's temperate regions, have historically been the main source of wood chips for the country. Much of the supply from managed hardwood and softwood plantations is more recent.
The high demand for paper combined with the native forests' relative affordability and availability in the late 1960s and early 1970s made woodchipping a feasible business idea. On the other hand, the development of the woodchipping industry allowed for the economically viable clearing of areas of substandard or mixed forest that would not have been possible to clear otherwise. In Australia, clear-felling is a contentious forest practice that has its detractors blaming the woodchipping sector for the practice's persistence.
Woodchips are processed into a fiber that is used in the textile industry to make different grades of paper or rayon. The majority of value-adding and processing happens outside of Australia. A low-cost, high-volume export good directly boosts the Australian economy.
Wood chips have long been used for centuries in a range of uses as a side effect of the timber business. For example, they have been a temporary floor covering in bars and butcher shops and a raw material for wallpaper. Wood pulp is the principal market for Australian woodchips.
"Woodchipping," the technique of making wood chips from most of a tree's woody material, was After that this became paper. Although hardwood pulp is mostly used in printing, softwood pulp is added for high-quality printing. This was a labor-intensive operation needing the use of bleaches and other dangerous materials. Mostly, Japan and other nations carried out the "Kraft pulping" step of the process. Australia's woodchip exports to Japan have grown thanks to specially built bulk carriers as demand for paper products rises.
Separating the chipping stage from the pulping and paper mills required the energy source—usually derived from process byproducts. Extra energy is needed for the transportation of raw materials and exporting the finished goods.
In contrast to the eastern states, Western Australia initially saw less opposition when the wood chip industry was introduced there in the 1960s. It was first viewed as a chance for the South West's economic growth; an environmental movement opposing it did not emerge until the 1970s. When two activists attempted to take down woodchip exporting facilities in Bunbury for eighteen months in 1976 through the unsuccessful Bunbury woodchip bombing, it was clear how volatile the issue was. Commercial forestry within native forests, including woodchipping, was outlawed in Western Australia and eastern Victoria in 2024 as a result of decades of advocacy by environmental groups and others.
The woodchipping industry in Australia presents a complex story of economic opportunity, environmental concerns, and the ongoing struggle for balance. While it has fueled economic growth and provided a valuable resource for paper production, the environmental impact of clear-felling native forests cannot be ignored. The shift towards plantation forestry and the rise of environmental opposition are positive steps toward a more sustainable future. The Regional Forest Agreements (RFAs) are designed to protect Australia's woodlands by balancing the economic interests of the woodchipping industry with the urgent need to prevent deforesting practices.
