Performed the steps for checking and accep- tance of the materials during the day, the waste is stored in a closed building in de- pression, while waiting to start the process of transformation. The first phase begins with loading material with an automated crane and placing it in press machines in order to obtain a squeezed material suitable as fuel for the production of gas. The squeezing is performed normally in complete automation.

The squeezed waste is sent into a storage tank and allowed to decant for a day long more or less in order to extract any inert sediments.

Sommo and Bascapè

ALAN SRL plants of 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 odor- ous 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 build- ings.

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 Ital- ian law.

Our company is actively participating in the Green Economy, returning purified substanc- es to the environment ready for the crop production, without affecting new natural re- sources.

Recovery of sludge from biological treatment

ALAN SRL plants of Sommo and Bascapè treat biologic sludge from industrial and urban waste water treat- ment 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 bio- mass without pathogens in order to respect the param- eters of the law and the authorization requirements. Once treated, the biomass is ready for agronomic use and it is stored in appropriate tanks in closed buildings. Our finished, product is transported to the fields of farmers affiliated with us for the purpose of fertilize the land.

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 requirements of the Italian law.

Our company is actively participating in the Green Economy, returning purified substances to the environ- ment ready for the new immission into the production cycle, without affecting new natural resources.
