DUMP YARD DETAILS |
|
|
Dump Yard is the place where we can receive and treat the MSW (Municipal Solid Waste) for Aerobic Composting. This stage has a key role in entire process i.e. MSW level to Finished Product (manure) level.
In this there are three types of activities involved, i.e.
|
|
Treatment of daily MSW |
• |
Treatment of under process material (windrows under turning operation) |
• |
Movement of Fermented Material |
|
|
TREATMENT OF DAILY MSW : |
• |
Preparation of Inoculums (Mix Bacterial Culture in water @ 1 Kg of culture in 8 ltrs. of water and sturr it properly by avoiding any lumps, in a container). |
|
|
• |
Soon after the receipt of the fresh MSW at Dump Yard (after unloading the MSW by dumpers in the Dump Yard), segregate the non-biodegradable bulk material, which can be picked up by hands, i.e. rubber tyres, corrugated boxes, plant stems, …….. etc. and keep it aside. |
|
|
• |
Already prepared slurry (inoculums of Microbial Culture) is to be applied on the fresh MSW @ 4 ltrs. Of slurry i.e. 500 gms. of culture per 1 MT of MSW (apply in a scattered way such that all the material can be mixed properly with Inoculums/ Slurry). |
|
|
• |
If the MSW is already segregated, then there won’t be any heavy particles. Then, this slurry can be directly applied on the MSW, soon after its receipt at yard. |
|
|
• |
After the Inoculation, the same material can be made into Windrows in a trapezoidal shape with the help of Front-end loaders, to suit the following dimensions: |
|
e.g. for 500 MT of waste: |
|
|
• |
Length 100 Mtrs. |
• |
Bottom Width 5 Mtrs. |
• |
Top Width 2 Mtrs. |
• |
Height 2.5 Mtrs. |
|
|
• |
Looking into the moisture condition, apply/ sprinkle water on the heap to maintain moisture level between 45% - 50%. |
• |
Once the fresh heap/ windrows is formed it has to be neatly dressed, by organizing the spillages near to the windrows, and leave it for decomposition. |
|
|
TREATMENT OF UNDER PROCESS MATERIAL: |
• |
Apply plain water on the heap every alternate day, by considering the atmospheric temperature so that the moisture level can be maintained properly. |
• |
Random check of temperature through the heap, with temperature gauge. With this we’ll come to know about the temp. generation inside the heap (60° C – 70°C) which is the good sign of decomposition. |
• |
If the temp. notices below 50°C at a particular place in the Windrow, it indicates that proper decomposition is not taking place at that particular block of the heap. Then, with the help of the back hoe excavator break that part of the windrows and rearrange at the same place. So that any non Bio-degradable material existing in that particular block will be distributed and balances the material. |
• |
During the process, if any leachates come out it can be routed through channels which leads to collection in the leachate tank meant for it. |
• |
Each windrows/ heap will be given a number, to make the history/ data of the heap. So that we can maintain a record sheet for every heap. |
• |
Every heap has to be turned up & down at weekly intervals for proper aeration. |
• |
Apply 300 gms. of culture (mixed with water as mentioned in the beginning) per ton of MSW, in a slurry form during 1st turning. |
• |
Maintain moisture & temperature during complete cycle. |
• |
After a week’s time from 1st turning, second turning to be done. During this turning 200 gms of culture (in slurry form) per ton of MSW to be applied just after 1st turning.
|
• |
Dress the heap after turnings and leave it for composting. |
• |
Likewise 3rd & 4th turnings and leave it for composting. |
• |
Except the non Bio-degradable things, all the organic material decomposes during this four weeks cycle and converts into rich Organic Manure. |
|
|
MOVEMENT OF FERMENTED MATERIAL: |
• |
After 4th turning disturb the heap and spread it for normal Sun drying. |
|
After Sun drying material has to be shifted nearby the Machinery area, with the help of Dumpers/ Front end loaders for Mechanical Segregation of Non Biodegradable. This will be fed to the Machinery for further screening. |
• |
During the Fermentation Process the volume of the Organic Waste is reduced by 40 – 50%. The controlled Aerobic Fermentation process is normally complete within 4-5 weeks time. |
|
|
SANITISATION |
• |
Due to hot weather condition and richness of bio solid in terms of Mineral Nutrition Protein and Carbohydrate Energy these Waste are quickly invaded by Pathogenic Micro organism and become the Source of Foul Smell and Spreading of Diseases. These Waste are also great source for multification of Flies which become the carriers for Pathogenic Bacteria. |
