  1. Recycling

  2. What is Recycling? Recycling is the reprocessing of materials into new products. It is a key concept of modern waste management and is the third component of the waste hierarchy.

  3. Waste Hierarchy • The waste hierarchy refers to the “3 Rs” or in other words reduce, reuse and recycle, which classify waste management strategies according to their desirability.

  4. Recycling Purpose • The purpose of recycling is to prevent useful material resources being waste. • Reduced the consumption of raw materials and energy usage. • Avoid gas emissions. • Conserve our environment

  5. Recyclable Materials Also called “recyclables” or “recyclates”, may originate from a wide range of source including the home and industry. Examples of these may be: • Glass • Paper • Aluminum, iron, asphalt • Textiles and plastics

  6. Benefits Recycling is beneficial in two ways: • It reduces the inputs (energy and raw materials) to a production system. • Reduces the amount of waste produced for disposal. For Example: Recycling aluminum saves 95% of the energy cost of processing new aluminum because the melting temperature is reduced from 900 °C to 600 °C. It is by far the most efficient material to recycle.

  7. Benefits Recycling reduces the environmental, social, and usually the economic costs of manufacturing. This means we are conserving and protecting the natural resources therefore we are helping planet earth with contamination problems.

  8. Causes of Pollution and Waste • Industry: We used a lot of products and therefore depend on them. But for products to be made they need to go through a process where they used energy. • Natural Causes: Natural fires on forests also produces a large amount of carbon dioxide. • Animals: Cows are one of the major producers of smog in the world. (it’s inevitable) • People: Along with industry are the major producers of pollution and contamination in aspects.

  9. Waste In 2005 the United States generated approximately 245.7 million tons of waste. It is important to keep in mind that all these waste materials take hundreds and sometimes thousands of years for it become part of the earth again. Processing techniques are not only costly but use a lot of energy so they can should be used as last option.

  10. How can we help recycle or stop polluting? • Try no to litter the streets and throw garbage to special recycling places. • Try to separate was in different categories for people in recycling center work more efficiently. • Try not to waste or make bad used of polluting resources such as gasoline and other gas emissions.
