Furfurylated Wood
Furfurylated wood is the end product of treating wood with furfuryl alcohol. This chemical process is also called ''furfurylation''. Furfurylation is a commercially used wood modification process to enhance the physical, mechanical and biological properties of wood. In this process -which is based on principles of wood science- the cell walls of the wood swell with furfuryl alcohol, which polymerizes within the cell walls. This treatment reduces the water absorption capacity of the wood, thus minimizing its tendency to deform with changes in moisture. The hardness and rot resistance of the modified wood are also improved compared to natural, untreated wood. The furfuryl alcohol used is obtained through the hydrogenation of furfural from biological agriwaste residues, such as husks and bagasse. Process In the furfurylation process, the walls of woody cells are initially swollen with the furfuryl-alcohol-based solution. Due to its polarity and size, furfuryl alcohol penetrates the ...

Furfuryl Alcohol
Furfuryl alcohol is an organic compound containing a furan substituted with a hydroxymethyl group. It is a colorless liquid, but aged samples appear amber. It possesses a faint odor of burning and a bitter taste. It is miscible with but unstable in water. It is soluble in common organic solvents. Synthesis Furfuryl alcohol is manufactured industrially by hydrogenation of furfural, which is itself typically produced from waste bio-mass such as corncobs or sugar cane bagasse. As such furfuryl alcohol may be considered a green chemical. One-pot systems have been investigated to produce furfuryl alcohol directly from xylose using solid acid catalysts. Although hardly a pure source of the compound, the Maillard reaction produces furfuryl alcohol (among many others). Reactions It undergoes many reactions including Diels–Alder additions to electrophilic alkenes and alkynes. Hydroxymethylation gives 1,5-bis(hydroxymethyl)furan. Hydrolysis gives levulinic acid.

Furan Resin
Furan resin refers to polymers produced from various furan compounds, of which the most common starting materials are furfuryl alcohol and furfural. In the resin and in the cured polyfurfurol, the furan rings are not connected by conjugation. The resins are generally used as binders for sand castings. The furan monomer is typically converted to a free-flowing resin with mild acid catalysis. Curing is achieved using strong acid. Types The term furan resins is not used uniformly in the literature. For example, some authors refer to resins based on furfuryl alcohol and furan as furan resins, while othersMichael Biron: '' Thermosets and composites : material selection, applications, manufacturing, and cost analysis.'' Elsevier, Amsterdam, 2014, , S. 257–259. use the term only for resins based on furfuryl alcohol. In addition to homopolymers of the two starting materials, also copolymers comprising for example methanal, urea or phenol are counted as furan resins.Arne Gardziel ...

Wood Polymer Technologies
Wood is a structural tissue/material found as xylem in the stems and roots of trees and other woody plants. It is an organic materiala natural composite of cellulosic fibers that are strong in tension and embedded in a matrix of lignin that resists compression. Wood is sometimes defined as only the secondary xylem in the stems of trees, or more broadly to include the same type of tissue elsewhere, such as in the roots of trees or shrubs. In a living tree, it performs a mechanical-support function, enabling woody plants to grow large or to stand up by themselves. It also conveys water and nutrients among the leaves, other growing tissues, and the roots. Wood may also refer to other plant materials with comparable properties, and to material engineered from wood, woodchips, or fibers. Wood has been used for thousands of years for fuel, as a construction material, for making tools and weapons, furniture and paper. More recently it emerged as a feedstock for the production of pu ...

Tropical Hardwood Hammock
Tropical hardwood hammocks are closed canopy forests, dominated by a diverse assemblage of evergreen and semi-deciduous tree and shrub species, mostly of West Indian origin. Tropical hardwood hammocks are found in South Florida or the Everglades, with large concentrations on the Miami Rock Ridge, in the Florida Keys, along the northern shores of Florida Bay, and in the Pinecrest region of the Big Cypress Swamp. Tropical hardwood hammocks are habitat for a few endemic plants and are critical habitat for many West Indian plant species when the northernmost portions of their ranges extend into South Florida. Tropical hardwood hammocks also provide important habitat for many species of wildlife, including nine federally listed species. While the majority of the remaining hammocks outside of the Florida Keys have now been protected, hammocks are still significantly threatened by development in the Keys. Tropical hardwood hammocks have been heavily impacted by outright destruction, c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forest Stewardship Council
The Forest Stewardship Council GmbH (FSC) is an international non-profit, multistakeholder organization established in 1993 that promotes responsible management of the world's forests via timber certification. This organization uses a market-based approach to transnational environmental policy. FSC is a global forest certification system established for forests and forest products. According to the council, the use of the FSC logo signifies that a product comes from environmentally, socially, and economically responsible sources. In addition to its global certification standard, FSC develops national standards in selected countries. The FSC has 10 Principles and associated Criteria (FSC P&C) that form the basis for all FSC standards and certification. FSC was established in 1993 as a response to concerns over global deforestation. It now has around 1200 members, including the World Wide Fund for Nature and IKEA.

Programme For The Endorsement Of Forest Certification
The Programme for the Endorsement of Forest Certification (PEFC) is an international, non-profit, non-governmental organization which promotes sustainable forest management through independent third-party certification. As of 2006, it was considered the certification system of choice for small forest owners in Europe. Its 48 endorsed national forest certification systems represent more than of certified forests. This makes it the largest forest certification system in the world, covering about two-thirds of the globally certified forest area. It is based in Geneva, Switzerland. History The Programme for the Endorsement of Forest Certification was created in 1999 by a group of European forest owners and managers, led by the Confederation of European Forest Owners (CEPF), to meet the growing demand for certification, particularly in developing countries where the costs of certification could be prohibitive.
