Pisa packs and piles storage plant

Solid waste can be stored either in containers placed in a special room, equipped with a leachate collection system, or in packs, placed on special shelves if small or directly on the ground on pallets.
The stored waste can be compacted or just stored for subsequent disposal or recovery. It is also planned to store in heaps the types of waste sent off for further treatment for the stabilisation and soil washing plant (or sent off for further treatment for external plants) in the room to the north of the plant and in the dedicated storage areas adjacent to the respective plants.
The activities are covered by the operations described under in points D13, D14 and R12

a) Waste Conditioning
This activity includes various types of measures to modify the waste packaging system in order to improve the possibility of transferring it to internal treatment departments or to improve transport safety to external disposal facilities, such as the following measures:

1. transfer of liquids or solids from poorly preserved or damaged containers, into other containers in good condition and that meet the characteristics required by the plants to which they must be delivered;
2. transfer of liquids or solids from small packages to larger and more easily transportable containers (e.g. drums, cisterns, containers or big bags);
3. packaging of shovellable sludge and solids in drums, small drums or bags, to be sent to the destination plant in bulk, in tanks.

b) Waste Sorting
This activity concerns the separation of different types of solid waste, which are mixed or packaged together or in any way combined, but are physically separable, such as for example:

1. sorting by separation of particular types of waste, to be sent off for further treatment to different disposal plants (for example, separation of nickel-cadmium batteries from mercury batteries, laboratory reagents, etc.);
2. packaging of obsolete products, already put on the market and therefore still in their original packaging, by dividing the contents from the packaging (for example, by separating pharmaceuticals in tablets from the glass bottle in which they are packaged and from the outer carton box);
3. transfer and reuse of drums or tanks that have contained waste, to accommodate other types of waste for temporary storage or remediation thereof, before sending it off for disposal or recovery of iron or plastic.

Waste type approval
Specific waste control procedures apply both when defining contracts with customers (the 'type approval' phase) and upon accepting deliveries to the plant.
The compliance of the quality of the incoming waste with the corresponding approval is checked by means of visual and analytical inspections, carried out instantly, periodically and on a 'spot' basis, including collection of waste samples. After checking, the waste is sent for the treatments defined in the approval phase.
