Plants
For more than thirty years we have been involved in the treatment and recovery of domestic and industrial sludge through technologically advanced, company owned plants.

Bascapè (PV)
Alan S.r.l. owns and operates a plant located in the municipality of Bascapè for storage and treatment of biological sludge, for subsequent reuse in agriculture, and fertilizer production with a maximum annual capacity of 66,000tons.

The first stage of the process allows for the stabilization and sanitization of biological sludge with lime to allow for its subsequent reuse in agriculture.
In accordance with D.L. 99/92, Art. 41 of D.L. 130 and subsequent regional regulations.
The second stage enables the production of an end-of-waste (EoW) corrective called "sludge defecation gypsum" in accordance with the process described by point 23 of All. 3 of D.L. 75/2010. This type of calcium sulfate is obtained by means of a hydrolysis reaction which is activated by adding to biological sludge pure lime and, subsequently, 96% sulfuric acid.
In accordance with the process described by item 23 of All. 3 of L.D. 75/2010.
Both treatment processes allow the recovery of the organic matter and nutrients contained in the biological sludge. This constitutes an example of a circular economy system.

The first stage of the process allows for the stabilization and sanitization of biological sludge with lime to allow for its subsequent reuse in agriculture.
In accordance with D.L. 99/92, Art. 41 of D.L. 130 and subsequent regional regulations.
The second phase allows biological sludge to be treated with pure lime and liquid CO2 in order to obtain a corrective called "defecation calcium carbonate." This treatment is a perfect example of a circular economy model of material recovery. Calcium carbonate, which is produced by adding CO2 by an amount that is 5 to 10% of the weight of the treated biological material, when added in the soil as a corrective, enables the sequestration of CO2 in the soil. Therefore, this contributes to the process of decarbonization of our planet.
In compliance with the process described in point 22 of All. 3 of D.L. 75/2010
