  • 40 IS ONLY RECYCLED OTHERS GETS MIXED
  • Glass recycling

    1. 1. Glass Industry and Recycling
    2. 2. What is Glass???
    3. 3. Glass is an amorphous solid material. Glass are typically brittle and optically transparent Glass is a hard material normally fragile and common in our daily life It is composed mainly of sand and an alkali
    4. 4. Main properties of glass
    5. 5. • Solid and hard material • Disordered and amorphous structure • Fragile and easily breakable into sharp pieces • Transparent to visible light • One of the safest packaging materials due to its composition and properties
    6. 6. Types of Glass waste
    7. 7. Soda glass or soda-lime glass Coloured glass Plate glass
    8. 8. Optical glass Pyrex glass Photo-chromatic glass
    9. 9. Lead crystal glass Safety glass Laminated glass
    10. 10. What is Glass Recycling???
    11. 11. • Process of taking old glass products and turning them into new, reusable glass products • Recycling old glass uses 40% less energy than manufacturing it from new • 100% recyclable
    12. 12. Recycling process
    13. 13. Collection • First the glass gets collected and is kept separately according to its colour Transportation • Second the glass is transported to the processing plant where contaminants such as metal caps and plastic sleeves are removed Crushing • Third the glass is then crushed into small pieces called cullet. It is now ready to be transported to the glass factory. Mixing • Fourth at the glass factory, the cullet is mixed with other raw materials used to make glass (sand, limestone and soda ash) and melted in a large furnace Melting • The molten glass is moulded into new bottles and jars
    14. 14. Outcomes of Recycling???
    15. 15. Benefits of Recycling???
    16. 16. • Glass can be recycled over again and never lose its quality or quantity • Creates less air pollution • Reduces water pollution • Saves enough energy to light a 100- watt light bulb for hours • It reduces landfill space
    17. 17. • Reduces CO2 emissions • Helps the environment • Cuts waste disposal costs • Increases public awareness of the benefits of recycling • Creates employment • Glass Recycling Pays
    18. 18. Negatives of Glass Recycling???
    19. 19. • Manual Labor Costs • Low Availability • Health Hazards
    20. 20. Future of Glass • Many new applications and manufacturing processes will involve glass in combination with other materials • There is an increasing need to combine optical and electronic devices for many applications such as transmission of audio, video and data information • Glasses and ceramics, either alone or composite with other materials, will find increasing application in biological and medical areas
