4. Definition of fruit Recycling  is the process of converting  waste  materials into new materials and objects. It is an alternative to "conventional" waste disposal that can save material and help lower  greenhouse gas  emissions (compared to plastic production, for example). Recycling can prevent the waste of potentially useful materials and reduce the consumption of fresh raw materials, thereby reducing:  energy  usage, air pollution (from  incineration ), and water pollution (from  landfilling ). 4/16/2017 4

5. What is Recycling? Recycling involves: Separating materials Collecting them Processing the materials Remanufacturing those materials into new products Buying those new products Using those new products

6. Recyclable materials Recyclable materials:  t he following materials can all be placed in the mixed recycling containers: Glass, paper, and metal,   tires , textiles, and electronics. Aluminium foil & trays. Cardboard. Food & drinks cans. Food & beverage cartons ( tetrapak type containers) Plastic bottles, tubs and trays. 4/16/2017 6

8. Benefits of Recycling Reduces the amount of waste sent to landfills and combustion facilities. Conserves natural resources such as timber, water, and minerals. Prevents pollution by reducing the need to collect new raw materials. Saves energy. Reduces greenhouse gas emissions that contribute to global climate change. 4/16/2017 8

9. Environmental Importance Recycling is very important as waste has a huge negative impact on the natural environment. Harmful chemicals and greenhouse gasses are released from rubbish in landfill sites. Recycling helps to reduce the pollution caused by waste. Habitat destruction and global warming are some the affects caused by deforestation. Recycling reduces the need for raw materials so that the rainforests can be preserved. Huge amounts of energy are used when making products from raw materials. Recycling requires much less energy and therefore helps to preserve natural resources. 4/16/2017 9

12. How plastic can be recycled? Plastic  recycling includes taking any type of  plastic  sorting it into different polymers and then chipping it and then melting it down into pellets after this stage it can then be used to make items of any kind such as  plastic  chairs and tables. Soft  Plastics are also  recycled  such as polyethylene film and bags. 4/16/2017 12

13. Steps to Recycling Materials Recycling includes the three steps below, which create a continuous loop, represented by the familiar recycling symbol. Step 1: Collection and Processing Step 2: Manufacturing Step 3: Purchasing New Products Made from Recycled Materials 4/16/2017 13

14. How recycling can reduce pollution? Solid waste material that ends up in landfills causes air  pollution  in the form of methane gas emissions.   Recycling  more waste  reduces  the amount of methane that escapes into the air.   Recycling  also  reducing  the production of virgin resources which process contributes to  pollution . 4/16/2017 14
