Vermi composter

this one use worms has internal machines to break leftovers. they don’t have teeth so the food must rothen first before is ready for them. and this is made by all the other microorganisms that also live in your composter. so when you put new lefts overs in this composter everything should be in small pieces, you dig a hole, cover and let them work. (i’m quite lazy with this cutting in small pieces, they will just take longer to break)

::: Bulding your home composter :::

A low cost solution for the recycling of organic waste, appropriate for apartments and urban housing that do not have a piece of land or an outdoor area.

To make this kind of composter, it is important to use stackable supports to separate the different stages of composting.

In this case, we'll reuse buckets of margarine 15L. You can ask for them for free at local businesses such as coffee shops, bakeries, juice houses, etc.. They are stackable and perfect for the job!

The first step is to cut the center of the lid that stands between the buckets. Leave a border so that a bucket can stay on top of the other (this kind of red lid is perfect for this because it comes with a delineated border):

Then we will make holes into the bottom of the buckets that will stay on top. These holes are to drain the leachate to be stored in the bucket underneath. You can use 4 or 5 mm drills, so that the worms can pass through.

We use thinner drills, size 1, or 1.5mm for making holes in the top of the buckets that receives organic waste. These holes are to allow entry of air.

A suggestion is to make a very beautiful painting in the buckets to forget all that margarine past and decorate your kitchen!

Now let's prepare the first bucket to receive our organic waste.

Place a layer of dry matter, leaves used in this case, and then a layer of compound or forest land. This land is rich in bacteria that will help in the decomposition process:

Now we can put our organic waste in little pieces!

Over time, the compound in the bucket begins to seem a dark mass:

When the bucket is already filled with this dark, pre composted mass, we put our dear worms! (if they enter at the beginning they might die with the heat generated)

We use the California red worms. You can ask for some for someone who already has a worm farm and soon they will reproduce and increase in number. You can also buy them from a producer or even through the internet.

Earthworms accelerate much the decomposition process because they can eat daily the equivalent of its own weight (!) Besides enriching the compound with their droppings, called humus.

When the upper bucket is full, it will be time to enter a third bucket on top of the stack, leaving the system as follows:

Now, the top bucket (with holes underneath, same process) will receive the organic waste generated by the house. Meanwhile the central bucket full of waste, will be resting while the worms do their work.

When the top bucket is full, it is time to use the compost in the middle bucket and then he will be free to start a new cycle!

And there you go ; )

Some very important things:

. The process of composting requires air and humidity (around 50% humidity)

. Try chopping food residues to facilitate decomposition.

. There is an Carbon x Nitrogen ratio to be maintained (initially 30:1). In practice, always cover the food waste with a good amount of dry matter such as straw, sawdust or leaves.

. The composting process generates heat, reaching between 60 and 80 degrees Celsius (!). Which is good because it helps kill the pathogens. When the temperature drops, this indicates that the compound is stabilized.

. What CAN go ::: - Fruits, vegetables, grains and seeds;

- Tea bags and coffee grounds (with filter).

- Leftover cooked or spoiled food (no exaggeration) and eggshells.

- Straw, dried leaves, wood shavings, sticks, garden pruning.

- Paper towels, paper napkins, bread paper, cardboard, newspaper.

. What MUST NOT enter :::

- Meat of any kind;

- Dairy products, oils, fats;

- Feces of domestic animals and used toilet paper.

- Excess of citric fruits (orange, lemon, pineapple, etc.);

- Excessive salt (leftovers), garlic and onion.
