Are uPVC Windows environmental safe?

Preserving the environment is one of the leading concerns, we, as a society, face today. Individuals and corporations alike must act responsibly and understand how the products they purchase and manufacture will affect the environment today and tomorrow. A number of factors can influence how “environmentally friendly” a product or industry is viewed. Those products and industries associated with recycling, energy efficiency and minimal waste disposal will have a definite advantage in the ever “greening” global marketplace. 

Plastic, once regarded as a substitute material that is used and thrown away, is becoming one of the most durable and widely recycled materials in the industry today. Plastic products have made an impact on modern medicine, global communications, transportation and food preservation. Plastics are also used in the preservation and protection of the environment in such ways as materials recycling and pollution prevention. Ironically, plastics, which were originally thought to be one of the larger of waste disposal problems, are now vital in the construction of material landfills. These facilities depend on plastic liners to protect groundwater by blocking toxic escape into the environment. Plastic drainage nets and textiles are used to remove the leachate and methane gas that collects inside the landfill, while plastic reinforcing materials and foam coverings save space, suppress odors and deter pests. Plastic products also conserve energy since they are lighter than alternative materials and use less fuel to transport. Plastic building components and insulation are extremely efficient in reducing conduction and infiltration into living spaces, lowering the amount of energy used for heating and cooling. Plastics generally require less energy to manufacture than equivalent products made of alternate materials. 

PVC is the world’s second most widely used plastic material. PVC, a non-hazardous white granular powder made from upvc chloride monomer, is fabricated into diverse upvc products having a variety of applications. upvc is predominantly used in construction and building applications that include window and door frames, sewer and water distribution pipe, drain, waste and vent plumbing pipe , flooring and wall coverings. upvc is an integral part in the manufacture of electrical wire and cable, packaging, furniture and coatings. A vast array of products found in the home and industry use upvc products because of their unique characteristics and low cost. Because most upvc applications are long-term uses that are not disposed of quickly, relatively little (about two and a half percent) is found in the waste stream. upvc is highly recyclable and can be incinerated safely without harm to the environment. Reground upvc is used to manufacture many items including mobile home skirting, PVC pipe and upvc siding. The small amount of upvc that is discarded is also environment-friendly. 

Studies conducted by independent bodies, such as the New York State Energy Research and Development Authority, have shown that the presence or absence of upvc waste in incinerator feed has no effect on the amount of dioxins produced by incinerators.* Dioxin production from any source can be minimized by carefully controlling incinerator operating conditions. pollution control equipment minimizes dioxin emissions, and scrubbers remove over 90 percent of the acid gases produced from the incineration. upvc also resists attack from the corrosive action of water and soil conditions typically found in landfills. It remains inert and will not leach harmful chemicals into groundwater. As the use of upvc and other plastics continues to increase, so does the need for continued research to develop more and stricter recycling programs and industry regulations.
