How does a Bokashi system work?

The Bokashi system is most compact of the three options, and is capable of taking the widest range of food items. It consists of two stacked buckets with a tight-fitting lid. The top bucket has holes in the bottom for drainage into the bottom bucket. 

To use, you just add your food waste to the top bucket, squash it (a potato masher works great!) and sprinkle the Bokashi “Zing” – a bran and sawdust product full of helpful microorganisms that ferment your food scraps. Over time, the food wasted is “pickled”, which cuts down on bad smells and helps it break down and turn into compost once it’s buried. 

What can I do with the finished product?

Bokashi is actually a pre-composting method. It produces a fermented material (“food scrap pickle”), which needs to be buried in the ground or added to a compost bin to finish the composting process. A liquid is also produced that can be diluted and used as plant food, or undiluted as a drain cleaner! 

What space is required?

4X 15L buckets are provided. Bucket systems are 43 cm high x 27.5cm x 27.5cm. This system performs best in a warm place away from direct sunlight. It can be kept outside under cover, like a carport or porch, or you can even try keeping it inside.

What you can put in:

Fruit and vegetables, cooked and uncooked meats, fish, cooked and processed foods, small bones and shells, citrus, cheese, eggs, bread, tea leaves, wilted flowers, tissues.

What you can’t put in:

Liquids (such as milk, water, fruit juice), paper, large bones, rubbish

Accessories that come with the Bokashi system

  • Two bags of Bokashi “Zing”
  • This is a kit that comes with two systems. This is because once your bin has been filled with layers of squashed food waste sprinkled with the bokashi “Zing”, you close it up and wait two weeks for it to ferment. During this time you can begin using the second  system so you never have to put food waste in the rubbish!
