- 13. FUTURE PLANS CONCLUSION, SOLUTIONS & RECOMMENDATIONS OBJECTIVES OF STUDYThe primary objective of this study is to investigate the solid waste management project of KalutaraPradeshiya Sabah. 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.
- 14. INTRODUCTIONSolid waste management project site is located at Nagoda area in Kalutaradistrict.It is quite large field with about 4 acres and started in March of 2011.
- 15. Earlier this was a area which used to dump garbage. This unproper dumping garbage system was a big problem for the villagers.
- 16. Because of that this solid waste management project was established by the Central Environment Authority.COMPONENTS AT THE SITEOffice room
- 17. Shed to store sorted garbage
- 18. Shed to store composts
- 19. Tank to store leachate
- 20. Well maintained home garden
- 21. Visitors lobby SOLID WASTE COMPONENTS THOSE ARE UNDERTAKEN TO THE SITEGarbage – Degradable materials (kitchen waste, rotten vegetables and fruits discarded from the markets.)
- 22. Rubbish - Polythene, Plastics, Glass, Textile, Metal Pieces
- 23. Construction Wastes - Tile Pieces, Metal Pieces
- 24. Well sorted polythene, plastics, glass and metalsSOLID WASTE COMPONENTS THOSE ARE NOT UNDERTAKEN TO THE SITESolid waste generated in the hospitals
- 25. Solid waste generated by industrial activitiesMATERIALS AND METHODS USED IN THE SITEFacilities provided
- 26. Electricity
- 27. Drinking water
- 28. Telephone
- 29. Machineries used
- 30. MJ. C. B. machine
- 31. Machine that used to cut coconut shell.
- 32. Electrical Sieve - 4mmOther Instruments used
- 34. Shovels
- 35. Hoes
- 36. Rakes
- 37. Bucketscollection of solid waste SourcesMarkets
- 38. Domestics
- 39. Industry wasteTransportation of collected solid waste to the siteBy covered tractors/trailers
- 40. Waste Management at the site First Step: Pre Processing Pre Processing involves sorting of wasteThey separate polythene, plastics, glass (by type and color), coconut shells and metals by hands.
- 41. Second Step: ProcessingProcessing is the actual composting method which is YARD COMPOSTING.
- 42. Third Step: Post ProcessingPost 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)
- 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
- 44. PRESENT MANAGEMENT PROBLEMSIncreasing of the amount of waste brought daily.
- 46. Workers are not encouraged properly
- 47. Not sufficient machineries are provided.
- 48. Public Attitudes SOLUTIONS Provide enough space and facilities
- 49. Well organization of the available space
- 50. Encouragement of the workers
- 51. Educate People
- 52. Encouragement of the public to reuse polythene or use degradable materials instead of polythene
- 53. FUTURE PLANSIncrease the number of the workers (by 3 this year)
- 54. Extend the space by purchasing the land next to the site (5 acres-approval had granted)
- 55. Educate public to do a proper sorting
- 56. Buy a vibrating sieve and a small machine to mix the waste (approval had granted)
- 57. Establish a bio gas plant
- 58. Improve the quality of compost
- 59. Increase the productivityTHANK YOU
