Food Scraps

At Somerville Primary School we recycle as much of our food scraps as we can.

Our goal is to send zero food scraps to landfill!

Food Scraps - fruit skins, cores, vegetable scraps, tea bags etc are collected in each learning space and in the staffroom.  We do not compost any bread or sandwich scraps as we do not want to attract rodents.  We encourage children to eat all of their sandwiches - crusts and all or take them home to the family pet! - and to let mum and dad know what they are not eating so food is not being wasted!

Harry and Emily from MJ are very keen monitors in the 2/3 area who diligently bring the compost buckets to the science room to be emptied.  They do this at the start of recess or lunchtime.

Ella and Sarah are taking responsibility for the compost buckets in the Senior building.

These scraps are recycled in one of three different ways:

  • Compost bins - located in the veggie garden
  • Worm Bins - also located in the veggie garden
  • Bokashi buckets - located in the Science room

What is Bokashi?

  •  Bokashi is a Japanese term meaning 'fermenting organic matter'
  • The food scraps are placed in the Bokashi bucket to ferment.  This means the scraps break down into simpler substances.  This is done without oxygen - anaerobically
  • The scraps are sprinkled with a Bokashi mix which looks like an unprocessed bran.  It has some friendly microorganisms mixed in!  These start the fermenting process!
  • The scraps are added each day and 'mashed down' in the bucket and sprinkled with the Bokashi mix.  The bucket lid is then placed securely on the bucket.
  • In the bottom of the bucket is a well that collects the liquid 'Bokashi tea' that is a product of the fermetation process.
  • The 'Bokashi tea' is drained off every few days and can be used as an organic fertiliser for the vegie garden, indoor plants or other outdoor garden beds.  These plants will get the benefits of the nutrients and microbes that are in the tea.
  • For the garden we dilute it down 10ml to 1 litre
  • If you pour it down the drain it will help keep the drains clean.  It is very useful in preventing sludge from building and blocking drainage fields in septic systems and is a good way to minimise problems in your septic system.  Just use the tea undiluted and pour it down the drain
  • When the bucket is full the contents are added to the compost bins.  Once placed in the compost bin the microorganisms and worms very quickly finish off the composting process
  • The compost is the used in our veggie garden

Sustainability

Somerville Primary School prides itself on taking the environment into account with it's programs.

The children participate in our Recycling programs and our Veggie Garden which uses grey water from our water tanks all year round.

Programs such as tree planting and rubbish collection are run periodically through the school and in conjunction with other organisations.
