Use of AdsorbEco in the Dump.

By adsorption Adsorbeco neutralises the odorigenous gases developed from the deposited mass of organic waste.

In dumps, the adsorption of smells takes place in a condition of equilibrium since the quantity of carbon and the slow release of odorigenous substances produced by the dump are in synchronism.

Tests carried out in dumps with AdsorbEco have shown that foul smells are removed for a period exceeding 90 days, thus reducing exhalations from 60 to 70%. After this period AdsorbEco is left in place and the operation is resumed with a new covering.

AdsorbEco’s resistance to wear, deriving from daily operations of removing and subsequent spreading, means that it can be used more than 90 times, but experiments carried out in recent years have demonstrated that its duration may even be two or three times greater if, however, it is used simultaneously on several working fronts.

The carbon foam remains active even if it gets wet, since rain creates a natural barrier to the odorigenous gases. Moreover, if the dump-front has a gradient of about 15%, only 20% of the rainwater penetrates the filtering fabric while 80% runs along its surface and it can be drained off before percolating into the waste. Given the enormous amount of adsorbent sq. m. per gram of carbon, AdsorbEco on drying is immediately ready to adsorb before the gases can pass through the protective barrier.

To facilitate covering and uncovering operations with the AdsorbEco tarps, special equipment has been designed which functions hooked up to the hoisting gear of a vehicle or tractor with a power of around 110/130 HP and works by taking off power from the vehicle’s hydraulic system.

Essentially it consists of a roller on which 6 metre wide AdsorbEco tarps of variable lengths are rolled which, hooked up together, can produce a total area of approximately 900 square metres.

The roller is automatically hooked up to the machine with a hydraulic self-centring system. When the tarp has been fixed to the ground with two restraints the machine proceeds, unrolling the tarp on a freewheeling basis.

Recovery of the tarp is carried out by using the machine with an empty roller and reversing the tractor; through a special hydrostatic system the machine suits the rolling speed to the speed of the tractor, stopping automatically once the threshold of tensioning is reached, this in order to avoid damaging the tarp. A special counter-roller keeps it perfectly stretched throughout its width.

The controls are servo-assisted by electro-hydraulic distributors governed from a keypad on board the tractor.

AdsorbEco anti-odour tarps are also used for covering heaps of compost, purifying plant tanks etc.. AdsorbEco tarps can be a valid aid wherever there is a problem of odour caused by organic waste.
