Become a real compost expert! Understand in 2 key steps

by | 10 Oct, 2021 | Uncategorized

Let’s start by giving you a simple overview because if you’re here, it’s because you really want to compost indoors. When you compost it’s always interesting to know how it works. So what exactly is it that turns your vegetable peelings into rich soil in which you give life to new plants? We’ll explain it all to you.
If you have done your research, you will have noticed that there are several solutions for indoor composting:

  • The vermicomposter (the one with the worms inside)
  • The Greenzy smart composter

At
Greenzy
we use the composting method called
aerobic
. This method is in contrast to anaerobic composting. So that you understand the difference, we have made a comparison chart.


Aerobic Composting

(Greenzy composter and vermicomposter)
Anaerobic Composting
(A poorly maintained outdoor compost pile)
– Demand for
oxygen

Process
fast
(2 months maximum with the Greenzy composter)
– Produces heat

– Gases released : Carbon dioxide
– Processes
without oxygen

– Slow
slow

– Produces almost no heat
no heat

– Gases released: carbon dioxide, methane and hydrogen sulfide (that’s what smells like rotten eggs)

The little tip : Aerobic compost that smells bad is simply being transformed into anaerobic compost because it lacks air. To remedy this, you don’t have to give him mouth-to-mouth resuscitation, but simply air him out 😉

The Greenzy composter needs oxygen but with it you have no risk of bad smells. We have put in place well thought out mechanisms to ensure that we never encounter this problem!

If you’ve heard of the Bokashi, the traditional Japanese method that is increasingly used here, and you’re wondering why it’s not on the list, it’s because it’s not really a composter. Indeed, this solution uses a process of its own. The main differences with the indoor composters mentioned above are the following:

  • Result of a
    fermentation
    and not a degradation.
  • Requires the
    addition
    of “bokashi bran” which will serve as an activator.
  • The result is not compost but a
    fertilizer
    .
  • The fertiliser produced cannot be used immediately, it must be
    mixed
    with soil or compost for 4 weeks.
    4 weeks
    . Only then can you put your beautiful plants in it or use it in your vegetable garden.

Now that you know a little more, we’ll explain what’s going on in your favourite peel-eater so that it can offer you this precious soil after 2 short months of waiting.
Who lives in your compost?
The design of the Greenzy composter has not only seduced you, but many
micro organisms
Many microorganisms are working on it every day to offer you a super quality compost! There are 3 main families of inhabitants:


  • The bacteria
    We’re talking about good bacteria here, of course, like when you hear about bacteria in your yogurt or even in your body.
  • Mushrooms
  • Actinomycetes

But what exactly are they doing there? This is what we’ll tell you right now:

1st step, they degrade

Not great these tenants, as soon as they arrive they make a mess… Don’t worry, trust them, the result will be great, I promise!

Turn on the heater!
During this first phase the microorganisms raise the temperature in your composter! The bacteria produce heat, a lot of heat, your composter becomes a real sauna for peelings and bacteria. The thermometer goes up to
60 to 70°C

Waste reduction.
Now that everything has heated up, it’s time to make room. The waste is very bulky so the microorganisms reduce it by
3 times their size!
But how?

Thanks to 2 phenomena:


  • The mineralization of organic matter
    into CO2.
  • Water evaporation . Your organic waste contains a lot of water and with the heat in there it evaporates.

Greenzy’s little extra: this water, also called “compost tea” or “compost juice” disappears without you even having to empty it or worry about it. A difference with the 2 other solutions mentioned above. Isn’t that nice?

Result of the degradation stage.
After all this work your composter contains so-called fresh compost but be patient, there is still some work to do before you can open your drawer and discover the final result.

2nd stage, the maturation

From the moment the waste is transformed into fresh compost then the decomposition process becomes slower. The micro-organisms continue to act to move from fresh compost to
mature compost.

For this, the temperature arrives at the same level as that of a summer day in the south of Spain, i.e. between
35° and 40°C
. Then the fungi and actinomycetes move into your favourite smart composter. They attack the fresh compost left behind by the bacteria and turn it into mature compost.

the 3rd step ?

It’s up to you.

All you have to do now is open the drawer of your composter and get your
nice soil
and thank all the microorganisms that worked hard to bring it to you.
If you don’t know what to do with them we advise you to read our article on flower gardens, we give you ideas of nice plants that will help the pollinators around you 😉
