HOW DOES THE PROCESS OF TURNING WASTE INTO COMPOST TAKE PLACE?
Composting is an aerobic biological process, which occurs in the presence of oxygen, and leads to the mineralisation of the biodegradable organic components in the ingoing waste.
This process occurs naturally in the environment, thanks to the use of
electromechanical composters, which act as composting accelerators; it can be conducted in less time and predefined spaces.
In the first phase of this process, known as thermophilic bioxidation, sanitisation of the waste takes place, the aerobic decomposition releases a considerable amount of energy in the form of heat, the temperatures (55-70°C) destroy pathogens and weed seeds.
In the second phase, the stabilisation of the waste takes place: the microorganisms, in the presence of oxygen, proceed with the oxidation of the organic matter, ensuring the production of a stable, quality compost with the correct degree of humification and moisture content, so that it can be used on land.
COMMUNITY COMPOSTING
This machine finds its use in community (or neighbourhood) composting - an intermediate way between industrial and home composting. It is an electromechanical machine, in which the aerobic process is maintained and accelerated by the continuous supply of air and the continuous movement of organic material.
The delivered organic material passes automatically into the first ripening chamber, where it is moved at preset intervals through mechanical arms and constantly oxygenated, thanks to an aeration fan.
In addition to a continuous supply of oxygen and optimum moisture content, a proper balance of carbon and nitrogen is required to promote the composting process.
Nitrogen is often predominant, so wood pellets are added to increase the presence of carbon, as well as to adjust the moisture content of the compound.
HOW LONG DOES IT TAKE TO GET COMPOST THAT YOU CAN USE?
After 30 days of processing, the contents of the first chamber are automatically transferred to the second chamber, where the second stage of the treatment process takes place.
Here the material continues to be handled and aerated for another 30 days, without coming into contact with new organic waste that would inhibit active processes.
At the end of the 60 days in the composter, the compost will be automatically discharged from the outlet and can easily be collected in a container. A further 30 days will be needed to complete the stabilisation cycle of the compost as required by the Italian regulations (90 days in total) and then it can be used on land.
