ALAN SRL plants of Sommo and Bascapè treat biologic sludge from biological waste water treatment plants.

Upon arrival of the trucks, the origin and composition of waste are assessed through identification forms. Once accepted, while waiting to be precessed, the sludge is stored into tanks in closed sheds to prevent odorous emissions. The material is taken from the storage tanks and led in a mixer with process reagents (lime and sulfuric acid).

The purpose of mixing and treatment is to obtain a biomass without pathogens in order to respect the parameters of the law and the authorization requirements. Once treated, the biomass is ready for agronomic use and is stored in appropriate tanks in closed buildings.

The product is then transported to the fields of farmers affiliated with us for the purpose of fertilize the land. Everything is done with the help of tractors and trucks that spread our material according to the quantities of the law. In some cases, according to the sludge types, they are added with sulfuric acid on a separate line in order to obtain a fertilizer (gypsum of defecation) that comply the Italian law.

Our company is actively participating in the Green Economy, returning purified substances to the environment ready for the crop production, without affecting new natural resources.
