Introduction to Bokashi composting
Food waste being dumped in landfill is such a terrible waste.
In addition to cutting food waste generally, instead ofthrowing the
scraps out, we should be composting it or adding it to a worm farm. But
having a compost heap or worm farm in the back yard isn't for
everybody. For example, if you live in particularly coldconditions, in
an apartment or simply don't have a back yard, what can you do?
Consider Bokashi composting
The
Japanese word "Bokashi" I've seen translated a couple of ways - either
"fermented, organic matter" or "shading off, gradation".
Bokashi composting occurs in an airtight container, meaning that it can be carried out inside the home.
It's
a pretty simple process - a layer of kitchen scraps are placed into a
speical bucket and then a carrier medium such as bran that's been
fortified with suitable micro-organisms is sprinkled on top. The
micro-organisms are usually lactic acid bacteria, yeast and
phototrophic bacteria.
The bucket is then sealed with an
air-tight lid; so the composting process in this case is carried out in
an anaerobic environment (meaning without oxygen).
The
layering process is repeated until the bucket is full, after which, the
contents are then allowed to ferment for a further 10 - 14 days. Given
the fermentation time, 2 buckets are often used so there's always a
batch on the go.
The buckets used in Bokashi composting also
have a tap to drain off the Bokashi juice. Like the leachate from a
worm farm, this juice makes for a great liquid fertilizer.
Once
fermentation is complete, the food retains some of its original
appearance, but will have a pickled look and unlike the earthy smell of
traditional compost, will have a cider vinegar type of odor.
The
Bokashi compost can then be dug into garden beds or planter boxes. It
will be acidic for around a week and will totally break down within a
couple of weeks; after which planting can begin. The compost will
provide the plants with nourishment while also enriching the soil with
beneficial micro-organisms.
A wide range of scraps can be used
in a Bokashi composting system, including fruit and vegetables, meat,
dairy products (excluding milk), eggs, bread, coffee grinds and tea
bags.
Bokashi composting has been rapidly gaining popularity in
recent years, so it's quite likely you'll find Bokashi buckets and the
EM (effective micro-organism) starter material at larger hardware
stores and garden outlets. I noticed during my last visit to our local
hardware store that they were now stocking full Bokashi composting
kits. There's certainly a lot of products also available online.
