Do you live in the city and in an apartment and would still like to be able to make your own compost?
Although it seems impossible at first glance, the vermicompost technique will allow you to make real compost at home.
Some tips for making your home composter.
What is vermicomposting?
Vermicomposting (or vermicomposting) is a technique that allows make your own compost indoors, and all odorless.
The principle is simple:
- in a container containing manure worms (called Eisenia foetidia) you put all your organic waste.
- These little critters will then eat them and the soil will be created by their droppings.
- While some people are content with a bin pierced on their balcony to make compost, vermicomposting gives much faster results.
- Plus, you don't have to do anything, the worms work for you!
Make an apartment composter
While vermicomposters can be expensive, it's quite possible to make one yourself.
For that it is enough:
- provide you with 5 bins of the same size and if possible that fit together,
- a cutter,
- manure worms
- and a little vegetable matter collected from a meadow near you.
For the bins, you can buy simple plastic boxes or try to recover the polystyrene packaging used to store the goods at your fishmonger for example.
And depending on the size of your fireplace, the dimensions must be adapted. For 2 people it is necessary for example to count 50 cm for the length and 40 cm for the width. If you are 4 people, you can almost double these dimensions.
Either way, the height of the bins must in all cases be at least twenty centimeters. And now it's time for manual work.
Here is how your apartment composter should be composed:
- Floor 1 (at the very bottom): a bin (you don't have to do anything) which will collect the juice
- Stage 2: a bin with small holes that must not let through the worms which will contain your ready-to-use compost
- Floor 3: a tray with holes 10 centimeters in diameter covered by wire mesh
- Floor 4: identical to floor 3
- Floor 5: a bin with the bottom cut which will serve as a booster to put more waste (unless your floor 4 is higher than the others).
And on top, do not forget to put a cover pierced with a few fine holes because the worms must be protected from light. If you have chosen polystyrene bins, also consider painting your apartment composter with a dark paint so that the light does not enter inside.
Once your apartment composter is finished,
- place a few leaves and twigs in it, along with a little dampened newspaper and soil.
- This will give you what is called a litter box.
- You can then add the worms at the rate of 500g for a 2-person apartment composter or 1.5kg for a 4-person composter. But at this point, no way to add your waste, the worms should acclimatize for a few weeks.
Only then can you place your fruit and vegetable peels, tea bags, coffee pods, eggshells, etc.
However, be careful not to add pieces of onion, garlic, fat or leftover meat or fish.
