Problem  [Edit]

On a global scale, garbage is a huge problem.  Some sites even suggest that 70-80% of the solid wastes disposed of are derived from organic materials (non glass or metal origin)*.  These materials are relatively simple to turn into resources such as fertilizers.  The most common method is to compost the waste.  However, to properly compost, one must pay quite a bit of attention to the materials and manage turning and temperatures to avoid causing odors and attracting pests (flies, rats, and birds). *http://www.unescap.org/pdd/prs/ProjectActivities/Ongoing/SolidWasteMngmnt/SolidWaste.asp

Action  [Edit]

The "bokashi" or "EM Method" comes from Okinawa.  Developed by scientist Dr. Teruo Higa, the method involves the use of a homemade inoculant called EM1 Bokashi.  Bokashi is a fermented bran that acts as a compost inoculant.  Food wastes are collected in the home and layered with the EM1 Bokashi and kept in an airtight bucket (that can be made or purchased).  After about 1-2 weeks of fermentation in the bucket, the materials are then buried in the ground to decompose.

Results  [Edit]

After about two weeks of fermenting the in the airtight bucket, the food waste is ready to bury in the ground.  It is placed in a hole and covered with 8-12 inches of soil.  In about two weeks all the food waste breaks down completely. 

  • You have diverted all food waste from landfill space and from composting.
  • You have made a free fertilizer for your plants
  • You have increased the organic matter in your soil
  • You have avoided producing greenhouse gases such as methane and ammonia that are normally produced during composting.
  • You can incorporate the wastes year round.
  • During the fermentation process, you can collect liquid from the buckets that can be used as a fertilizer at a rate of one teaspoon per gallon of water.

Limitations  [Edit]

You can have problems if you don't keep the containers airtight when not in use.

If you are collecting the liquid, you have to drain it at least every other day so it won't go bad and smell foul.

If you do not add enough EM1 Bokashi to the bucket, fermentation will not be complete enough and will cause odor.

If you don't cover the food waste with enough soil, it may attract animals which will happily eat it.  No harm will come to them, but they will make a mess.
