Importance of recycling

  1. 1. IMPORTANCE OF RECYCLING PRESENTED BY AHMAD JAMAL ASAD SARFRAZ DANIYAL MAJEED
  2. 2. DEFINITION  “To process something in order to regain material for human use.”  Other terms:  REUSE  ALTER  RECOVER
  3. 3. ORIGIN  Recycling has been a common practice for most of human history, with recorded advocates as far back as Plato in the fourth century BC.  In pre-industrial times, there is evidence of scrap bronze and other metals being collected in Europe and melted down for perpetual reuse.  Paper recycling was first recorded in 1031 when Japanese shops sold re- pulped paper.
  4. 4. Why recycling should be done?  Recycling is one of the best ways for you to have a positive impact on the world in which we live. Recycling is important to both the natural environment and us. We must act fast as the amount of waste we create is increasing all the time.  The amount of rubbish we create is constantly increasing because:  Increasing wealth means that people are buying more products and ultimately creating more waste.  Increasing population means that there are more people on the planet to create waste.  New packaging and technological products are being developed, much of these products contain materials that are not biodegradable.  New lifestyle changes, such as eating fast food, means that we create additional waste that isn’t biodegradable.
  5. 5. RESEARCH RESULTS • A study conducted by the Technical University of Denmark according to the Economist found that in 83 percent of cases, recycling is the most efficient method to dispose of household waste. • Dumping 10,000 tons of waste in a landfill creates six jobs while recycling 10,000 tons of waste can create over 36 jobs. • However, a 2004 assessment by the Danish Environmental Assessment Institute concluded that incineration was the most effective method for disposing of drink containers, even aluminum ones
  6. 6. TYPES OF RECYCLING • E-recycling (Computer recycling) • Plastic recycling • Chemical recycling • Wood Recycling • Glass Recycling • Textiles Recycling • Bricks/Inert Waste Recycling • Waste Paper Recycling & Cardboard Recycling
  7. 7. E-Recycling(Computer Recycling)  Used electronics which are destined for reuse, resale, salvage, recycling, or disposal are also considered e-waste.  Electronic scrap components, such as CPUs, contain potentially harmful components such as lead, cadmium, beryllium, or brominated flame retardants.
  8. 8. Plastic Recycling  Plastic recycling is the process of recovering scrap or waste plastic and reprocessing the material into useful products.  Soft Plastics are also recycled such as polyethylene film and bags.
  9. 9. Chemical Recycling  Chemical recycling refers to operations that aim to chemically degrade the collected plastics waste into its monomers or other basic chemicals.
  10. 10. Glass Recycling  Glass recycling is the processing of waste glass into usable products.  Glass waste should be separated by chemical composition, and then, depending on the end use and local processing capabilities, might also have to be separated into different colors.
  11. 11. Wood Recycling  wood recycling is the process of turning waste timber into usable products.  Recycling timber is a practice that was popularized in the early 1990s as issues such as deforestation and climate change prompted both timber suppliers and consumers to turn to a more sustainable timber source.
  12. 12. Textiles Recycling  Textile recycling is the process by which old clothing and other textiles are recovered for reuse or material recovery.  It is the basis for the textile recycling industry.
  13. 13. Bricks/Inert Waste Recycling  Bricks are classed as Inert Waste and can be sent to landfill, subject to a Landfill Tax rate of £2.50 per tone.  However, many types of brick can be recycled as fill material, aggregate or re-used if the mortar can be removed cleanly.
  14. 14. Waste Paper Recycling & Cardboard Recycling  The process of waste paper recycling most often involves mixing used/old paper with water and chemicals to break it down.  It is then chopped up and heated, which breaks it down further into strands of cellulose, a type of organic plant material; this resulting mixture is called pulp, or slurry.
  15. 15. Process of Recycling
  16. 16. IMPORTANCE OF RECYCLING  Important for Environment.  Important for People.  Important for health.  Conservation of Material.  To save Energy.  Reduce garbage in landfills.
  17. 17. 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.  Minimize pollution(Air, water and land).
  18. 18. IMPORTANCE TO PEOPLE  Recycling is essential to cities around the world and to the people living in them.  No space for waste. Our landfill sites are filling up fast, by 2025, almost all landfills in the UK will be full.  Reduce financial expenditure in the economy. Making products from raw materials costs much more than if they were made from recycled products.  Preserve natural resources for future generations. Recycling reduces the need for raw materials; it also uses less energy, therefore preserving natural resources for the future.
  19. 19. ADVANTAGES  Less energy usage  Reduce usage of new raw materials  Protects nature  Minimize Global Warming  Conserves Natural Resources  Fuel saving Economical benefits  Creation of jobs  Lower cost recycled material
  20. 20. Three “RE” for a better World
  21. 21. If Recycling is not done!  A lot of POLLUTION will happens.  Natural Habitats will be destroyed.
  22. 22. People attitude towards recycling Majority of the people doesn’t contribute towards recycling and think it is as if the matter is of no importance. Actually, these are the people who doesn’t want to make a world a better place. Everyone should play his part regarding this issue as the matter is critical and not trivial. Govt Role regarding recycling Legislation has also been used to increase and maintain a demand for recycled materials. Four methods of such legislation exist: minimum recycled content mandates, utilization rates, and recycled product-labeling. But unfortunately, these rules are being followed to some extent. The major hindrance is the attitude of the people. If people are being aware that what kind of serious part recycling is taking in their life, then the government rules will be seriously followed.
  23. 23. What Can Be Done?
  24. 24. THANK YOU.
