Step 2: put the activator!

Introduce a tablespoon of activator each time you add waste to the Ecovi® kitchen composter. The Ecovi® activator combines wheat bran and anaerobic microorganisms.

The active microorganisms are in a dormant state in the activator. Without water or food, the microorganisms wait to be in contact with your kitchen waste to activate and transform it into liquid fertilizer and organic compost.

General information about the bioprocess in place:

Digestion in the kitchen composter is a process of decomposition of rottable (putrescible) materials by bacteria that act in the absence of air. This decomposition process is called "anaerobic fermentation".

The principle is as follows: organic waste is stored in a sealed tank called a "digester" or "kitchen composter" in which it is subjected to the action of micro-organisms (bacteria) in the absence of oxygen. The biological reactions involved in this process are complex, but overall there are three main stages:

  •     hydrolysis and acidogenesis: complex organic chains (proteins, lipids, polysaccharides) are transformed into simpler compounds (fatty acids, peptides, amino acids);
  •     acetogenesis: the products of acidogenesis are converted into acetic acid;
  •     methanogenesis: acetic acid is transformed into methane and carbon dioxide.

Once digested, the residual material (digestate or compost) is stored or can be mixed with soil.

digestate is a fertilizer product with a high agronomic value. It is very easily assimilated by plants because it is mainly composed of ammonia, a product of nitrogen transformation.

Did you know that?

According to scientific theories, the bacteria present in the Ecovi activator were the first living organisms to appear on Earth more than 3 billion years ago, at a time when oxygen did not yet exist in the atmosphere. They fed on organic molecules present in their environment as they do today and transformed the carbon dioxide and hydrogen contained in these molecules into methane and oxygen.
