  8. 8. ADVANTAGES<br />Prevents waste of potentially used materials<br />Reduce the consumption of fresh raw materials<br />Reduce energy usage<br />Reduce air & water pollution<br />Recycling of a material would produce a fresh supply of the same material<br />eg: Paper recycling<br />
  9. 9. RECYCLABLE MATERIALS<br />Glass<br />Paper<br />Plastics<br />Metals<br />Textiles<br />
  10. 10. RECYCLABLE MATERIALS<br />Biodegradable Materials<br />Industrial Materials<br />
  11. 11. COLLECTION OF RECYCLATES<br />Drop off centre's<br />Buy back centre's<br />Curbside collection<br />
  12. 12. REUSE<br />
  13. 13. REUSE<br />This includes conventional reuse where the item is used again for the same function, and new-life reuse where it is used for a new function.<br />To reuse is to use an item more than once.<br />
  14. 14. Reuse envelopes.<br />Reuse single-sided paper for scratch paper.<br />Reuse foam peanuts and other packaging material.<br />Use remanufactured or surplus office equipment.<br />Use rechargeable batteries.<br />Use rechargeable fax and printer cartridges.<br />Compost grass clippings and food waste.<br />Donate toys and other items to charity.<br />

  22. 22. Gift bags</li></li></ul><li> ENERGY RECOVERY<br />
  23. 23. ENERGY RECOVERY<br /><ul><li>Includes any technique or method of minimizing the input of energy to an overall system by the exchange of energy from one sub-system of the overall system with another.
  24. 24. The energy can be in any form in either subsystem, but most energy </li></ul>recovery systems exchange thermal energy in either sensible or latent <br />form.<br />
  25. 25. EXAMPLES<br /><ul><li>Heat recovery is implemented in heat sources
  26. 26. Regenerative brake
  27. 27. Active pressure reduction systems</li></li></ul><li>REDUCE<br />REDUCTION MEANS TO MAKE<br />SOMETHING SMALLER<br />USE SOMETHING LESS OFTEN<br />
  28. 28. How to Reduce ?<br />Do I really want this item?<br />How long will thw item will last?<br />Can the item be reused after I am finished with it?<br />Is the item made from recycled materials?<br />Is the item recyclable?<br />How is the item packaged?<br />Do I need a bag to transport the item?<br />
  29. 29. WHAT DO THE 3 ARROWS STAND FOR?<br /><ul><li>Collection of Recyclables
  30. 30. Manufacturing of the Material
  31. 31. Buy Recycled Products</li></li></ul><li>Practice the <br />3 R’s of Management<br />Reduce<br />Reuse<br />Recycle<br />
  32. 32. WHAT YOU CAN DO ??<br />
