problems with plastic wood products

  • Colour fade is still a problem, attributed to UV protection on that exposed cellulose content. Some suppliers have addressed this by using 100 per cent PVC products or plastic coatings over the top of boards which also protects from scratches, stains, mould and slipping. Generation one products were made from recycled pine saw dust and polyethylene (milk bottles) and this soft plastic and soft wood combination translated into a product that was easily scratched by& ...


  • Cellophane: plastic made from wood. Composed from cellulose, a tree and plant component, cellophane is one of the first plastics ever made. It can be obtained through sustainable growing practices or as byproducts of wood harvest. BioMass Packaging<sup> </sup> carries cellophane products made from NatureFlex a 100% cellulose bioplastic with excellent oxygen, grease, oil and moisture barrier characteristics. NatureFlex bags are certified to be both home compostable& ...


  • based company, Envirolastech Inc., says the plastic not only outperforms wood in strength, but also does not rot or split, problems that sometimes occur with traditional wood lumber. The company's plastic also resists fading, which is common to other types of plastic lumber, Schmitt says. The company has tested the plastic lumber and found that cold temperatures do not make it brittle, which is a common problem with plastics. In fact, just the opposite happens; the& ...


  • plastics did not really take off until after the First World War, with the use of petroleum, a substance easier to process than coal intomaterials. plastics served as substitutes for wood, glass and metal during the hardship times of World War's I & II. After World War II, newer plastics, such as polyurethane, polyester, silicones, polypropylene, and polycarbonate joined polymethyl methacrylate and polystyrene and PVC in widespread applications. Many more would follow and by the& ...


  • Limit use of: o wood-plastic composites because of concerns about mixing biological and synthetic materials, including limited end-of-life recyclability. o fiberglass-reinforced or polystyrene-blended “structural” plastic lumber to demanding structural applications such as railroad ties and bridge supports, as a less toxic alternative to chemically treated wood. o products with multiple commingled recycled consumer plastics as they will have more contaminants and inconsistent properties.


  • wood-Composites. Traditional wood-composite materials are typically manufactured using 50% plastic and 50% organic wood material, such as sawdust or other recycled wood fibers. This makes the product harder to recycle, and still contributes to the destruction of our forests through the use of a wood-filler. wood-composites are susceptible to stains, mold, mildew, and insect problems. They require replacement more quickly than recycled plastic lumber, and require more& ...


  • wood is also protected under the convention on the Trade in Endangered Species and companies such as Premier Forest products will not trade in timber species prohibited by the body. Why use wood instead of other materials? Using wood means you aren't using less environmentally friendly alternatives like plastic, steel or aluminium. wood is renewable unlike fossil fuels or mineral based products. Across the product lifecycle, wood products achieve negative CO2 emissions& ...


  • As a consequence, substantial quantities of end-of-life plastics are accumulating in landfills and as debris in the natural environment, resulting in both waste-management issues and environmental damage (see Barnes et al. .... Downgrading is a term sometimes used for recycling when recovered plastic is put into an application that would not typically use virgin polymer—e.g. 'plastic lumber' as an alternative to higher cost/shorter lifetime timber, this is secondary& ...


  • GreenScapes website1, in fact, appears to wholeheartedly endorse plastic lumber over traditional materials for a wide variety of applications. But is sweeping endorsement justified? Is everything that is being said, in fact, true? A bit of investigation into WPC performance to date suggests that caution may be in order when considering such products. For instance, various sources document a number of problems that have been encountered with plastic composite.


  • products that do not involve cutting trees down. Substitute wood! (American plastics. Council 2004). Consumers of wood products and substitutes. To get quality at the minimum price, preferably without damaging the environment. wood products can be of variable quality. The environmental benefits of using different alternatives are unclear.

  • A material's environmental impact is both very close to home and far away, so let's take a closer look at what is the best stuff to make furniture with: wood, metal, or plastic. ... For the most part, furniture products are generally composed of plastic, wood or metal which of these materials is the most environmentally friendly? ... The new Herman Miller Environment collection includes the Eames Aluminum Group Lounge Chair, the Executive chair and the Compact sofa.


  • Manufacturers' past claims (hyped by the press and public) that WPC and PVC were maintenance-free certainly helped confuse things, and intense competition has led producers to be intentionally vague about what's in their products. Should you demand to know what's in this stuff? Well, since 2004, seven wood-plastic composite manufacturers and suppliers have faced lawsuits related to a host of problems, including fading and color changes, slippery surfaces, shrinkage, swelling,& ...


  • It's lightweight, durable, and waterproof. You don't have to paint it; but it holds paint well. But there is one drawback: plastic trim doesn't move because of moisture the way wood does, but it does move because of temperature. And unlike wood (which mostly shrinks crosswise), PVC trim grows and shrinks along its length—a lot. A long run of PVC fascia on your eave or rake easily could shrink an eighth of an inch between summer and winter—enough to be noticeable,& ...


  • But the evidence for plastic timber's durability is thin, in part because the industry arose only about two decades ago, says Jim Bowyer, a wood scientist at Dovetail Partners, a non-profit environmental consultancy based in Minneapolis, Minnesota. The first generation of plastic timber had problems with sagging and rot; newer products are better, but their long-term performance is hard to predict. “I know of one lab that has gotten mushrooms to grow on it,” Bowyer says.
