  • The Miracle Resource Eco-Link
    Since 1989 Eco-Link Linking Social, Economic, and Ecological Issues The Miracle Resource Volume 14, Number 1 In the children’s book “The Giving Tree” by Shel Silverstein the main character is shown to beneÞ t in several ways from the generosity of one tree. The tree is a source of recreation, commodities, and solace. In this parable of giving, one is impressed by the wealth that a simple tree has to offer people: shade, food, lumber, comfort. And if we look beyond the wealth of a single tree to the benefits that we derive from entire forests one cannot help but be impressed by the bounty unmatched by any other natural resource in the world. That’s why trees are called the miracle resource. The forest is a factory where trees manufacture wood using energy from the sun, water and nutrients from the soil, and carbon dioxide from the atmosphere. In healthy growing forests, trees produce pure oxygen for us to breathe. Forests also provide clean air and water, wildlife habitat, and recreation opportunities to renew our spirits. Forests, trees, and wood have always been essential to civilization. In ancient Mesopotamia (now Iraq), the value of wood was equal to that of precious gems, stones, and metals. In Mycenaean Greece, wood was used to feed the great bronze furnaces that forged Greek culture. Rome’s monetary system was based on silver which required huge quantities of wood to convert ore into metal. For thousands of years, wood has been used for weapons and ships of war. Nations rose and fell based on their use and misuse of the forest resource.

  • A Future Vision for Optimally Using Wood and Biomass
    June 2008:Forest Products 6/5/08 9:09 PM Page 6 Integrated Biomass Technologies: AA Future Future Vision Vision for for Optimally Using Abstract Exciting new opportunities are emerging for sustainably meeting many global energy needs and simultaneously creating high­value bio­based consumer and construction products from wood, forest and agricultural residues, and other bio­based materials. In addition to traditional value­added bio­ based products, such as lumber, paper, paperboard, and composites, opportunities are now on the hori­ zon for biorefining to produce electricity, transportation fuels, chemical feedstocks, syngas, and nanocrystalline cellulose. In the near future, nanocrystalline cellulose, produced as a high­value by­prod­ uct from the biorefining process, could likely compete with carbon fiber for use in innovative high­ strength biocomposites. The holistic view of how to achieve both traditional and new high­value materi­ als with enhanced performance properties from renewable resources is called Integrated Biomass Technologies. This concept promotes the use of sustainable, bio­based, environmentally neutral (or even beneficial) technologies to meet global demands for building and materials end uses, chemicals, and energy. This concept provides a systematic approach for maximizing value, performance, resource sus­ tainability, and improving profitability in the agriculture and forest products industries. 6 JUNE 2008 June 2008:Forest Products 6/5/08 9:09 PM Page 7 By Jerrold E.

  • Eco-Link Linking Social, Economic, and Ecological Issues
    Eco-Link Linking Social, Economic, and Ecological Issues Volume 11, Number 2 What’s Good About Wood Wood is a remarkable fi ber and a miraculous resource. It has played a major role in the development of civilizations for thousands of years. As John Perlin explains in his book, A Forest Journey, throughout the ages trees provided wood to make fi re, the heat of which allowed our ancestors to reshape the earth for their use. With heat from wood fi res, relatively cold climates became habitable; inedible grains were changed into a major source of food; clay could be converted into pottery, serving as useful containers to store food; people could extract metal from stone, revolutionizing the implements used in agriculture, crafts, and warfare; and builders could make durable construction materi- als such as brick, cement, lime, plaster, and tile for housing and storage facilities. There are many reasons why wood is superior to other raw materials. Wood is available in many species, sizes and shapes to suit almost every need. It has a high ratio of strength to weight and a history of excel- lence in durability and performance as a structural material. Dry wood has good insulating properties against heat, sound, and electricity. It is easily shaped with tools and fastened with adhesives, nails, screws, bolts, and dowels. Wood resists oxidation, acid, saltwater, and other corrosive agents, and it can be treated with preservatives and fi re retardants. While some wood can rot, most species can easily be treated with chemical preservatives. The grain patterns and colors of wood make it an esthetically pleasing material, and its appearance can further be enhanced by stains, varnishes, lacquers, and other fi nishes.

  • A History of Export Woodchipping from North East
    History of Export Woodchipping A HISTORY OF EXPORT WOODCHIPPING IN NORTH EAST NSW Dailan Pugh, August 2013 This paper outlines the Commonwealth‟s extreme reluctance over many decades to meet its obligations to oversee the introduction, expansion, and constraints on export woodchipping in north- east NSW. It in part explains their desire to absolve themselves of all responsibilities by signing Regional Forest Agreements, but also chronicles the political over-riding of environmental obligations by successive Commonwealth resource ministers. In early 2013 Boral were unable to get Forest Stewardship Council accreditation for a pile of woodchips it had amassed and thus could not sell it. They announced they were going to close down their export woodchipping operations. There is now an intention to replace woodchipping with the burning of forest residues for electricity, meaning any tree not classed as a sawlog. The history of woodchipping provides a salutatory lesson as to how we could expect an industry based around burning of native forests for electricity could develop. Though with less restrictions on species and quality, and the ability to locate processing facilities all over the north coast, the environmental consequences could be far worse. By the late 1960s the New South Wales and Western Australian Governments were in negotiations with Japanese companies to supply them with woodchips, and Tasmania, Victoria and the Northern Territory were being mooted. On 14 November 1967 NSW Premier Robert Askin announced that Harris-Daishowa would construct an export woodchip mill at Twofold Bay near Eden. Exports started in 1971. Tasmania started exporting woodchips in 1972 and West Australia in 1975.
