Observe that the smoke disappears. This is not an illusion, but illustrates that the by-products of incomplete burning are still flammable. Incineration burns the material and then the by-products of the initial burning. Polymers affect every day of our life. These materials have so many varied characteristics and applications that their usefulness can only be measured by our imagination.
Polymers are the materials of past, present, and future generations.
A growing number of communities were implementing recycling programs in an effort to decrease the volume of waste subject to rising tipping fees at landfills. In some cases, test programs were driven by state-level recycling mandates. The SPI code was developed to meet recyclers' needs while providing manufacturers a consistent, uniform system that could apply nationwide. Recycling firms have varying standards for the plastics they accept. Not all types of plastics are generally recycled, and recycling facilities may not be available in some areas.
