If you see black or blue-green mould in the bin, this means that your waste is rotting instead of fermenting. 

Bury your rotting waste in at least 10cm of soil in the ground or a large pot of soil, wash the bin thoroughly, and start again!

To keep this from happening in the future, make sure you:

  • Close the lid tightly
  • Add enough enzyme spray
  • Tap out bokashi juice frequently
  • Keep the bin in a relatively cool area
