What’s composting?

In nature, all organic substances produced which is not useful to life (fruit, berries, mushrooms, dry leaves, carcasses and so on) is decomposed by microorganisms and insects present in the ground and in the organic substances themselves until water, carbon dioxide, mineral salts and humus are obtained. Humus is a chemical component of the ground, homogenous, characterized by a brownish color and made by various products derived by degradation and reprocessing of the ground organic substance.

With composting, this natural process is reproduced in a more controlled way and, most of all, in a shorter time. Composting is also known as biostabilization.

Our ancestors have always tried to imitate nature. They mixed wet material rich of ozone, like animals feces or kitchen and garden discards, with dry material rich in carbon, like straw. After, they used the obtained product after a long period of maturation as fertilizer in fields and gardens.

What is compost?

Compost is a mixture of natural substances, the results of the above described process controller by man. The substances which decomposing make the compost, are organic biodegradable and divided into:

  • wet: fruit and vegetables discards, coffee residue and the filters, moldy bread, egg shells, cut grass;
  • dry: dry leaves, straw, sawdust, branches, bark, common paper and kitchen paper, carton.

All this represents insects’ food, molds, earthworms, mushrooms and bacteria that have the duty to decompose animals and vegetal rests, transforming them into brownish and scented ground; for this reason they are called “decomposers.”

A distinction between industrial composting and home composting is due.

Industrial composting is garbage recycling

In our previous blog articles we talked about differentiated waste collection. In the differentiated collection field, industrial composting on large scale is a organic waste recycling process which obtains an optimal fertilizer, called compost. We will talk about compost, soil improvers, fertilizers and natural fertilizers in a deeper way in one of the next blog articles.

4 good reasons to do home composting

Let’s focus on home composting, that can interest and involve us all directly. There are different good reasons to dedicate part of our time to composting:

1) The first good reason is a environment-driven awareness that makes us understand how much our dedication would contribute to solve “at the source” the organic waste problem. Using a part of wet waste to produce compost, we would reduce the quantity that someone else has to manage for us with difficulties and high costs, through a normal waste management process.

2) The second good reason is that the organic material present in the waste, the main ingredient of composting, is the one that, if discarded at a landfill, causes part of the disturbing odor typical of these places and nearby areas. By composting, we can avoid that landfill stink.

3) The third good reason is that composting is a nice and satisfactory activity, and can become a play time for the kids.

4) The fourth good reason is purely economical: one night, not knowing what to do, we took part to a community meeting held to incentivize home composting. During the meeting, we were informed that the municipality will give an economical incentive to those who will buy a home composter and, in the future, for those who will do home composting there will be a discount on the waste tax. Regarding this matter, did you know that there are already many towns and cities that have in their regulations reduction of 10,20,30 % of the waste tax’s variable part for those who can prove that use home composting for organic waste, contributing in a strong way to the reduction of organic waste that would normally be collected. There are “virtuous” municipalities that, based on the families necessities, give small or big sized composters free of charge. Have you ever asked to your municipality if they provide any reduction?

What does the future of composting look like?

We would like to see soon cities that give the same reduction also to industries and commercial users that decide to give their contribution to environment, totally reducing in a drastic way at the source organic wet waste deriving from their activities, i.e. restaurants, hotels, supermarkets, canteens, hospitals, etc. In fact, a huge part of the millions of tons of organic waste that we produce comes from industrial and commercial structures.

To reduce wet waste production these structures may use community composters, a larger and more technological version than the traditional home composters. Or, in lack of space or green outdoor areas, use new technologies, like our Ecodyger system. Ecodyger Pro is able to reduce organic waste produced from a minimum of 70 up to over 90 % of its original volume and weight.

Ecodyger gives at the end of its cycle a solid residue that, based on the chemical analyses made, has all characteristics of a “mature” quality compost, ready to use. In a few hours, today technology is able to replicate composting advantages, but in smaller space and shortest time, without any odor production and particular control activities or maintenance.
