    • OBJECTIVES OF STUDY
      The 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.
    • INTRODUCTION
      • Solid 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.
      • Earlier this was a area which used to dump garbage. This unproper dumping garbage system was a big problem for the villagers.
      • Because of that this solid waste management project was established by the Central Environment Authority.
    • COMPONENTS AT THE SITE
      • Office room
      • Shed to store sorted garbage
      • Shed to store composts
      • Tank to store leachate
      • Well maintained home garden
      • Visitors lobby
    • SOLID WASTE COMPONENTS THOSE ARE UNDERTAKEN TO THE SITE
      • Garbage – Degradable materials (kitchen waste, rotten vegetables and fruits discarded from the markets.)
      • Rubbish - Polythene, Plastics, Glass, Textile, Metal Pieces
      • Construction Wastes - Tile Pieces, Metal Pieces
      • Well sorted polythene, plastics, glass and metals
    • SOLID WASTE COMPONENTS THOSE ARE NOT UNDERTAKEN TO THE SITE
      • Solid waste generated in the hospitals
      • Solid waste generated by industrial activities
    • MATERIALS AND METHODS USED IN THE SITE
      • Facilities provided
      • Electricity
      • Drinking water
      • Telephone
      • Machineries used
      • MJ. C. B. machine
      • Machine that used to cut coconut shell.
      • Electrical Sieve - 4mm
      • Other Instruments used
      • Garbage transportation carts
      • Shovels
      • Hoes
      • Rakes
      • Buckets
    • collection of solid waste
       
      Sources
      • Markets
      • Domestics
      • Industry waste
    • Transportation of collected solid waste to the site
      By covered tractors/trailers
    • Waste Management at the site 
      First Step: Pre Processing
       
      Pre Processing involves sorting of waste
      They separate polythene, plastics, glass (by type and color), coconut shells and metals by hands.
    • Second Step: Processing
      Processing is the actual composting method which is YARD COMPOSTING.
    • Third Step: Post Processing
      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)
    • 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
    • PRESENT MANAGEMENT PROBLEMS
      • Increasing of the amount of waste brought daily.
      • Unorganized work premises
      • Workers are not encouraged properly
      • Not sufficient machineries are provided. 
      • Public Attitudes
    • SOLUTIONS
       
      • Provide enough space and facilities
      • Well organization of the available space
      • Encouragement of the workers 
      • Educate People
      • Encouragement of the public to reuse polythene or use degradable materials instead of polythene
    • FUTURE PLANS
      • Increase the number of the workers (by 3 this year)
      • Extend the space by purchasing the land next to the site (5 acres-approval had granted)
      • Educate public to do a proper sorting
      • Buy a vibrating sieve and a small machine to mix the waste (approval had granted)
      • Establish a bio gas plant
      • Improve the quality of compost
      • Increase the productivity
    • THANK YOU
