you are making a difference:

  • Return your food scraps to the earth to enrich the soil, reduce waste and reduce carbon emissions.

how does it work:

  • Cut up your food scraps and throw them into the Urban Composter bokashi bucket.
  • Spray Compost Accelerator onto the scraps every time they are added (recommend 3-5 sprays evenly over scraps).  Bokashi mix can also be used if desired.
  • Push scraps down to compact the layers each time.
  • Ensure lid is sealed correctly all the way around as air contact may affect the fermentation process.
  • Drain the juice off every few days.  This can be diluted (1:100) with water and used as a fertiliser.  Alternatively this can be poured down the sink and acts as an organic drain cleaner.  
  • Ensure the bucket is left for at least 1-2 weeks after it is full to ensure all contents are fermented.  Ensure all juice is drained off.
  • Bury under soil or place on compost heap where it will break down in 4-8 weeks and can be planted into.
  • When emptied clean only with fresh water as this won't harm microbes inside composter.

Will last forever

I have the original spray and this refill and I haven't had to open the refill yet (after around 7 months), so this will keep you going for ages. Does smell, but dissipates once you close the lid on your Bokashi bin.

Love the option of a refill bottle

So glad this is available as the spray bottle stopped working for us. To be able to buy a 1L refill also means saying some money.

Economical choice

Great option to refill an existing Urban Composter Compost Accelerator Spray bottle. The whole Urban Composter system is absolutely fantastic and I love the fact that the spray helps hurry the whole process along when compared with a traditional compost system.
