Ambisystem^® is a technology devised, developed and patented by Ambientalia for the aerobic stabilisation of organic material and for accelerated maturation of compost.

The organic part of the waste (previously selected) is suitably mixed with structuring material (woodchip), if the material to be stabilised consists of damp waste from differentiated collection or if it is a discard from mechanical separation with chopping and riddling ≥ than 50 mm.

The product thus prepared is introduced, with a rubberised shovel, into a tubular polyethylene container (“ambioTunnel”) with the special “ambiPress” bagging machine. Thanks to the closed and modular structure of the ambioTunnel it is possible to stabilise directly in the open air, on a waterproofed bed or directly onto a suitably prepared dump body.

The special system with partial air recirculation, both ingoing and outgoing with regard to the biomass, avoids the leakage of odorigenous particles, of gases and vapours, which are automatically recovered and introduced into the stabilising mass without creating environmental problems.

The polyethylene ambioTunnel has the function of containing the biomass and percolate in a closed sheath. The gases formed during the bio-stabilisation process are in part reintroduced and in part filtered by the exclusive system of ambiCover tarps which retain the minimum part of gas and malodorous substances that are not sucked in by the recovery pipes inside the upper part of the tubular container.

The process is carried out directly outdoors, without causing any problems of environmental impact, dispersion of waste due to wind or uncontrolled leakage of percolate.

Waste stabilisation takes place by means of forced aeration. A fan blows air the whole length of the ambioTunnel and recovers it through perforated pipes inserted automatically during the filling phase.

“AmbioTunnels” have a diameter of 3 metres and their variable lengths go to a maximum of 50 metres. They can hold from 3,500 to 4,000 kilos (approx.) per linear metre of material to be stabilised. (The maximum weight per linear metre depends on the type of material and the dampness it contains).

The frontal progress and the limited bulk of the “ambiPress” machine make for easy manoeuvring in any area chosen for positioning the “ambioTunnels”.
On completion of the operation of ensilaging the biomass, various technical data are fed into the computer: Type of process (green, damp, riddled damp etc., weight of material introduced into the ambioTunnel), length of ambioTunnel, humidity of material.

“Ambicontrol”, the management and control software, processes the input data and the work process begins. The start of the aerobic process causes a controlled increase of the temperature inside the ambioTunnel.

Control
The entire process is controlled by our exclusive ambiControl software.

Temperature
The temperature is taken continuously by three PT100 probes inside every ambioTunnel. It is transmitted to the management and control system which can modulate, by means of an inverter, the air delivered by the fan, this with view to maintaining the best operational conditions for the bio-stabilisation process.

Oxygen
Control is carried out by a digital probe inside the fermenting biomass. Analysis by this exclusive system allows modulation of fan delivery to maintain the right quantity of oxygen in the ambioTunnel. This is done by means of a modulating valve controlled by the software. It also reduces electricity consumption to a minimum during the process. The application of ambiSystem is suitable for both composting plant (damp etc.) and biological stabilisation of S.U.W. FOS.

Consumption
Electricity consumption is on average one tenth (1/10) in comparison with an equally powerful plant of the traditional bio cell type.
