Subjecting organic waste to a process of controlled aerobic decomposition, obtaining compost.
Es la versión acelerada del proceso de descomposición que en la natureza da lugar al humus, responsable de la riqueza de nutrientes, de la correcta absorción de la luz, de la humedad, de la aireación y drenaje de los suelos, y, en definitiva, de su calidad.

It is a natural fertilizer with excellent properties for the soil generated from the recycling of organic waste.


It is carried out in composting plants, usually from organic waste separated at source by citizens and collected in a municipal or district framework.

Intermediate alternative between industrial composting and home composting It is carried out in schools, gardens, among the neighbours of a house, etc.


La masa vegetal está a Tª ambiente y los microorganismos mesófilos se multiplican rapidamente. Como consecuencia de la actividad metabólica la Tª se eleva y se producen ácidos orgánicos que bajan el pH.

When a temperature above 40°C is reached. These thermophilic fungi disappear and bacteria appear, the thermophilic microorganisms act by transforming nitrogen into ammonia and the pH of the medium becomes alkaline. At 60 ºC these thermophilic fungi disappear and sporogenic bacteria and actinomycetes appear. These microorganisms are responsible for breaking down waxes, proteins and hemicellulose.
When the Tº is less than 60 ºC, thermophilic fungi reappear and reinvade the compost and decompose the cellulose. When the temperature falls below 40 ºC the mesophiles also restart their activity and the pH of the medium drops slightly.
It is a period that requires months at ambient temperature during which humic substances (compost) are produced.


It is the best known technique and is based on the construction of a pile formed by the different raw materials.

It consists of spreading a thin layer of finely divided organic material on the ground, allowing it to decompose and gradually penetrate the soil.
It is one that we each develop in our homes through an individual composter.
It is developed jointly by all the members of a community, by means of a larger urban composter installed in public spaces with free access.
As these are larger productions, they require the use of Big Hanna technology.




A well-made compost is dark in colour and the original components are not recognised.
If it smells like forest soil, it is well composted and can be used without problems.
A good compost has a loose and grainy texture. If when you take a handful and squeeze it with your hand, the compost does not drip or crumble, it is good.


Due to its lumpy character, it facilitates the formation of conglomerates, thus allowing it to maintain correct aeration and humidity.
Given its condition of natural product, without chemical compounds is free of pathogens, acts in many cases as a bactericide and fungicide.
As it is a product rich in nutrients and macronutrients, it becomes an excellent fertilizer, contributing to the plants' greater resistance to pests and diseases.


It gives off a characteristic and pleasant smell that is reminiscent of the smell of the rainforest.
No, if the process was carried out correctly. If mosquitoes, ants, flies, etc. appear, we are not doing it correctly.
No, if we have placed the composter in a shady or semi-shady situation.
Yes, because it is a completely natural product.
