Recycling and Other Applications

Recycling, recovery and reprocessing of waste materials for use in new products. The basic phases in recycling are the collection of waste materials, their processing or manufacture into new products, and the purchase of those products, which may then themselves be recycled.

Building homes from Plastic

Green Technologies Group Limited Products has technology to manufacture buildings using recycled plastic waste. The target market is the developing world where the need for affordable houses, refugee shelters, temperature controlled units for storage of food and medicines, and camps (hospitals, schools, temporary living) for disasters and emergency situations is massive.

Plastic timber materials, when used in place of treated lumber, are resistant to flies, rot, corrosion, and a variety of chemicals.

Manufacturing of Raw Materials for Composite Panels

Green technologies group limited presents the innovative process of material upgrading the fairly cost-effective industry standard raw material made from regenerated cellulose for composite panels.

Types of Material Used

There are two types of plastic-lumber products: “composites” (wood products made from a combination of plastics and natural fibers) and “wood-like” products made entirely of plastics. Many of these items use recycled plastics, which diverts waste from landfills and can benefit the atmosphere. The plastic lumber industry owes its existence primarily to the discovery of a use for plastic scrap and post-consumer plastic waste. These modern products are now displacing conventional construction materials in some applications. Global demand for these plastic lumber products is increasing, owing to a growth in their potential building applications.

Wood–plastic composites (WPCs) are made up of fibers mixed with a polymer. Natural fiber composites, for example, blend nylon with flax or hemp. This content first gained popularity in Western Europe with German automakers. Natural composites currently average between 7 and 10 kg (15 and 22 lb.) per vehicle in nonstructural applications such as interior panels, headliners, seat panels, parcel racks, and acoustic panels for companies such as BMW and DaimlerChrysler.

Wood composites, on the other hand, are materials made from a mix of wood fibers and plastics. Their different properties (including longevity and weather resistance) make them ideal for outdoor construction applications such as decking/railing systems, window/door profiles, shingles, highway sound walls, and infrastructure items such as boardwalks, picnic tables, and park benches. Natural fiber and wood composite materials will also be manufactured from virgin plastic or post-consumer/industrial reclaimed material. Virgin polymers have more cosmetic alternatives, such as pigmentation options and reproducible patterns, but they can also be more expensive. Specialty additives/pigments, such as color preservation and ultraviolet (UV) ray protection, can be used in potentially less costly composites using recycled plastic to increase aesthetics.

Polyethylene (PE) is the most commonly used polymer in composite applications in North America. However, due to increased use of the commodity and increasing exports abroad, post-consumer supply is tightening. This, along with ongoing research into new polymer compositions and processing methods (for example, injection molding), which increase demand for other plastic materials such as polypropylene (PP). As this occurs, these new materials can deliver their own distinct properties and characteristics, further altering how specifiers and other design professionals perceive WPCs. (Polypropylene, for example, may be oriented to have greater stiffness.)

Green construction promotes longevity and resiliency, as well as low maintenance and a long-life span. Plastic timber has many benefits over its more conventional predecessors.

According to a US Army Corps of Engineers report, composite materials are long-lasting, stable, flexible, and resistant to weather, rust, mildew, and termites (without chemical pressure-treatment). Furthermore, plastic lumber materials do not need to be repainted or restrained on a daily basis. These materials are also workable with standard carpentry equipment and, for the most part, require little maintenance.
