* A material that contains one or more organic polymers of large molecular weight, solid in its finished state and at some state while manufacturing or processing into finished articles, can be shaped by its flow * When plastic was first discovered, it was considered to be a revolution in the world’s industries. It was extremely durable, light weight, water and chemical-resistant, insulator and versatile. It could be molded into almost any shape. Its properties could be modified to satisfy particular technical needs. Deemed as a boon for the packaging industry, it was readily adopted.  withstand extreme physical conditions, it is non-biodegradable * However, the very same qualities of plastic have now become a menace for this planet. Due to the ability of plastic to. This means that it cannot be broken down into simpler substances by microbial action. Hence, a plastic bag once manufactured, will not decompose and stay in the environment for years together, doing it great harm.  A large number of fish, marine birds and animals like cattle and turtles are choked to death everyday by swallowing plastic bags. `

Recycled plastics are being used every day in new construction projects. They can be blended with ‘virgin’ plastics or with other materials, such as wood, sawdust, and fiber composites. Polymeric timbers made from recycled plastics are used in everything from fences and decks to picnic tables. Plastic from beverage bottles is even being spun into fiber for carpeting.

A one-year study1 found that the use of plastic building and construction materials saved 467.2 trillion Btu of energy over alternative construction materials. That’s enough energy saved over the course of a year to meet the average annual energy needs of 4.6 million U.S. households, or all of the households in 11 states: Following are some examples of plastic building products that promote the efficient use of energy and other resources: 2.ROFFINGS:

* Roofing systems made with spray polyurethane foam (SPF) offer durability, energy savings and moisture control. This foam can be used to cover an existing roof, helping to reduce the amount of building materials sent to landfills. 3.WALLS

* In walls, the use of structural insulated panels (SIPs) made with expanded polystyrene (EPS) can help homeowners save hundreds of dollars annually on heating and cooling bills. Savings vary by material and products. EPS starts out as a plastic pellet and ends up as nearly 95 percent air, a very effective insulator. * Vinyl is increasingly found in durable, easy-to-clean vinyl wall coverings and requires only half as much energy to manufacture as the same amount of paper wall coverings.  4.WINDOWS

* Plastics also rival traditional materials for windows and frames. For example, polycarbonate—a material also used in eyeglasses—is used in windows. These lightweight, shatter-resistant plastic products have low thermal conductivity, which can help to reduce heating and cooling costs. * Vinyl window frames save the U.S. nearly 2 trillion thermal units of energy per year, helping reduce the greenhouse gas emissions associated with energy generation—all the while cutting maintenance time, materials and costs. 5.PIPING

* Polyolefin, polyvinyl chloride (PVC), and acrylo-nitrile butadiene styrene (ABS) pipes and fittings, offer excellent fusion integrity for continuous pipeline systems, helping to eliminate potential leak points where water could be wasted. * In residential use, cross-linked polyethylene piping (PEX) is effective in manifold systems—due to its flexibility, lightness, and ease of installation—allowing multiple feed lines...
