The most recent development in EM technology is that of EM ceramics. EM ceramics have antioxidant properties and also stimulate the regenerating activities taking place in the soil. EM Super Cera C ceramic powder is used for soil conditioning and has the power to retain fertilisers. Ideally used in conjunction with EM Actiferm soil activator, enhancing the effects of the live microbes in EM Actiferm and helping retain the nutrients for plant growth.

This EM Super Cera C powder is specially made to convert your organic waste into a high-quality fermented compost. It is an alternative to using the Bokashi Bran (which is made from wheat bran). But it can also be used in addition to Bokashi Bran to make an even richer Bokashi. Using our unique EM Super Cera C ceramic powder together with Actiferm results in a better soil conditioning.


  • EM ceramics have antioxidant properties and also stimulate the regenerating activities taking place in the soil.
  • Converts organic waste into high-quality fermented compost.
  • Suitable for use in the EM Kitchen Waste Bokashi compost buckets, resulting in a higher quality compost with less chance of failure.


  • The EM Super Cera C powder can be used in a wide variety of areas around the house and garden.
  • It can be used to improve the living conditions of effective microorganisms in the soil.
  • Suitable for improving planting or growing soil and is helpful in obtaining kitchen bokashi.
  • The powder can also be added to compost or other organic fertilisers.
  • It can also be added to paints, varnishes, screeds, concrete, clay, or adhesives and promotes positive vibrations in house construction.
  • The powder can also be used excellently for cosmetic purposes in creams, peelings, or masks that you mix yourself.*

*Strain the powder carefully over a fine sieve before mixing.


  • Carefully mix 5 teaspoons powder with 50 litres garden soil and use immediately.
  • On pot plants or vegetable patch: Mix 2 to 10 grams powder (per M2) with fine sand or fine dry earth, spread evenly, and work into the ground lightly.
  • Kitchen Waste bokashi buckets: Add a teaspoon to the bokashi when added to the food waste.
  • Foliar plant spraying: Mix 10g to 10L unchlorinated water and spray with a large nozzle.

EM contains a beneficial vibration that enhances the powers of life and that positively influences the whole living world. This vibration also exists in EM-X and in EM ceramics and can therefore be applied to many different areas of water purification and agriculture and even to industrial situations.
