Technology description

The process of production is characterized by following phases.

Contribution:

Organic and plant waste is delivered separately. The pre-treatment of the organic fraction is then performed in the transfer department, separating the unwanted fractions (plastics, metals, etc.) from the organic component using specific equipment called "squeezer" and then mixing the different waste matrices in the quantities determined by the shovel. gummed.


Treatment:

Waste undergoes an aerobic treatment: treatment takes place in a large enclosed space in a depression environment. The intake system constantly conveys the air present in the covered structure into the external filters of 752 square meters to be purified.

Screening and maturation:

During this phase the product stabilizes and becomes enriched with humic molecules. This is the treatment phase (known as a curing phase), characterized by processes of transformation of the organic substance whose maximum expression is the formation of humic substances.

Distribution:

The compost is ready to be reused in agriculture, nursery and hobby. The duration of the biological transformation process to obtain the compost is 90 days and the accelerated phase of the process takes place in 28 ventilated boxes. The air sucked in by the aerobic treatment department is purified, before being released into the atmosphere by a double abatement stage: scrubber (washing the air with water jets) and natural biofilter.
