We concerned on the present situation: sources of waste generation, processes used to manage solid waste, effectiveness of the processes, effects and impacts on public. Then we suggested modifications which can be done and then we have made some recommendations using the knowledge gained in the lecture series.<br />

  15. 15. Earlier this was a area which used to dump garbage. This unproper dumping garbage system was a big problem for the villagers.
  16. 16. Because of that this solid waste management project was established by the Central Environment Authority.</li></li></ul><li>COMPONENTS AT THE SITE<br /><ul><li>Office room

  38. 38. Domestics
  39. 39. Industry waste</li></li></ul><li>Transportation of collected solid waste to the site<br />By covered tractors/trailers<br />
  40. 40. Waste Management at the site <br />First Step: Pre Processing<br /> <br />Pre Processing involves sorting of waste<br />They separate polythene, plastics, glass (by type and color), coconut shells and metals by hands. <br />
  41. 41. Second Step: Processing<br />Processing is the actual composting method which is YARD COMPOSTING. <br />
  42. 42. Third Step: Post Processing<br />Post processing involves only the reduction of microbial activity as they don’t maintain the N, P, K values. (They proved by experiments that the there are suitable N, P, K value in their compost)<br />
  43. 43. Composts are stored separately for about week in order to reduce microbial activity. Then they are filled into bags (2kg, 5kg, 25kg, and 50kg) and stored until sold to the customer<br />
  44. 44. PRESENT MANAGEMENT PROBLEMS<br /><ul><li>Increasing of the amount of waste brought daily.
  45. 45. Unorganized work premises
  46. 46. Workers are not encouraged properly
  47. 47. Not sufficient machineries are provided. 
  48. 48. Public Attitudes </li></li></ul><li>SOLUTIONS <br /> <br /><ul><li>Provide enough space and facilities
  49. 49. Well organization of the available space
  50. 50. Encouragement of the workers 
  51. 51. Educate People
  52. 52. Encouragement of the public to reuse polythene or use degradable materials instead of polythene</li></li></ul><li>
  53. 53. FUTURE PLANS<br /><ul><li>Increase the number of the workers (by 3 this year)
  54. 54. Extend the space by purchasing the land next to the site (5 acres-approval had granted)
  55. 55. Educate public to do a proper sorting
  56. 56. Buy a vibrating sieve and a small machine to mix the waste (approval had granted)
  57. 57. Establish a bio gas plant
  58. 58. Improve the quality of compost
  59. 59. Increase the productivity</li></li></ul><li>THANK YOU<br />
