The biodigester is a container where several organic materials are deposited and are digested by anaerobic bacteria. These bacteria produce biofertilizers and biogas, used, for example, in the generation of energy. The gas generated in the process is captured and used for power generation.

Geomembranes are used for tank waterproofing, and Bio blanket is used for tank covering.
The low permeability and excellent chemical and mechanical resistance of the biodigester bottom guarantee tightness, and the Bioblanket covering have the flexibility required to absorb movement during the inflation process.
