  • 1. Garbage in, Garbage out!
  • 2. Introduction
    • Garbage is an unwanted or undesired material or substance
    • It is also referred to as rubbish, trash or junk
    Common rubbish in a bin bag A dumpster full of waste awaiting disposal
  • 3. How do we deal with Garbage? Landfill Safai karamcharis collect the garbage in trucks and take it to a low lying open area, called a landfill
  • 4. The garbage at the landfill is separated as Useful component The part of the garbage that can be re-used is the useful component . This component is then treated by different processes to make it non-toxic Non- Useful component The part of the garbage that cannot be used is the non-useful component which is then separated and spread over the landfill and covered with a layer of soil
  • 5. Useful garbage includes Animal Dung Dead Plants Paper which can be recycled to get useful products
  • 6. Now let us have a look at how the useful component is treated Composting recycles organic household waste and manures into an extremely useful humus-like, soil end-product called Compost Converting plant and animal waste including that from kitchen, into manure, is called Composting
  • 7. What is VermiComposting? Vermicompost is a nutrient-rich, organic fertilizer and soil conditioner Mixture of Red Worms along with the garbage to be composted The method of preparing compost with the help of redworms is called Vermicomposting
  • 8. What is a Red-Worm? How does it help in Vermicomposting? Redworms do not have teeth. They have a structure called ‘gizzard’, which helps them in grinding their food Redworms do not survive in very hot or very cold surroundings They also need moisture around them The Worms are put into the pit containing the useful component of the garbage The Worms then convert the garbage into useable compost that can be used in gardens or fields for the plants and crops
  • 9. What is Recycling?
    • Recycling involves processing used materials into new products in order to prevent the waste of potentially useful materials
    The international recycling symbol We can recycle waste paper and make it into new products. Paper suitable for recycling is called “Scrap paper"
  • 10. Can we recycle everything just like the way we recycle paper? Household items made of plastic
  • 11. The most important point to know and think about is More garbage we generate, more difficult it will be to get rid of it We need to generate less waste and find ways of dealing with the increasing amount of garbage in our surroundings
