Kitchen Waste Composting- Bucket method

Following is a description of kitchen waste composting method. Contributed by Mr Aniruddh Deshpande. He practically does it at his house.



Two Stage Anaerobic Composting ( Bucket Composting)

Purpose of anaerobic composting – After composting aerobically ( in presence of air) for years,
I  realised that , I needed a more convenient and faster  method for managing the kitchen waste.
Here is the composting method which is not only faster and more convenient but it also generates far
superior quality compost.

The process in details –
You ll need –
‐‐‐‐ 2 same size buckets with lids
‐‐‐‐Anaerobic   Inoculation powder

Procedure:

  1. Take 2 buckets (dustbins) with lids. This is a bucket in bucket. Drill  8 to 10 holes of 5mm  to 10mm diameter spaced randomly at the bottom of the inner bucket. ( The size and number of the holes  is not critical.)
  2. The outer  bucket is as‐it‐is and used for collecting the excess liquid coming out of the inner bucket.
  3. Start filing the inner bucket with daily kitchen waste.  
  4. Every time , on top of it , sprinkle 2 tea spoons of inoculation powder. ( so that it covers the top layer.) Cover the lid tightly after each filling. 
  5. Keep on filing and compacting the contents , till the bucket is full to about 1 inch below the rim. Keep the bucket  aside and closed , for about 10 days.
  6.  Every 2 days drain the liquid collected in the outer bucket. 
  7. This liquid is excellent plant manure after diluting with twice the amount of water.
  8. After 10 days, the contents of the inner bucket are mixed with old compost or soil.
  9.  In about 25 days , the contents transform into  good , black soil with refreshing  aroma.
  10. In the mean while, Start filling the second buckets set .
  11. The End product ‐ Compost.

His comment about different methods of composting

"For wet waste, composting being a natural process, - all roads ll lead to it. We are merely trying the most convenient way to facilitate the natural process.
Vermi compost though is the best process, is not the most convenient. It is laborious to keep the worms alive.
Hence I finally shifted to this method. It is indeed amazing to find the amount of wet waste that can be handled /managed in so little space, little efforts and no time. On top of that,� all wet waste can be put into this-� veg, non veg (incl fish) , cooked, uncooked,� dairy, cut, un-cut. No rules. Lemon, orange rinds ,Maize cobs etc."

  1. I follow much the same method with following adaptations-
    1. I stir the basket periodically.
    2. I keep my 'first' bucket in a mud filled pot. So the soil soaks the leachate
    3. After anerobic stage, I put the material into another pot and add some vermicompost. In a few days earthworms come and chomp the waste into fine 'vermicompost'

  2. I was studying the various methods of composting and one reference mentioned anaerobic composting as releasing methane- which is a greenhouse gas. I was left wondering about the prudence of using Mr Deshpande's method- whether it is really environment friendly or not? He explained to me that the special bacteria he uses ensure methane is not produced. I invite him to respond and clarify in greater details.
