We developed and put in operation an original system of biogas extraction that combines the deep capture of vertical wells with a horizontal draining. This technique was later applied to a great number of projects.

The BSDV capture system allows the draining and the re injection of liquid residue of the landfill according to needs.

Our nets are equipped with biogas captivation – patented BSDV – that permit the depressurizing adjustment of the extraction net, according to the quantity of extracted methane.

Our nets guarantee, on one side, the elimination of biogas migration risks out of the installations, on the other, a reliable continuous extraction thanks to a conception that prohibit the risk of plugging of the conductors, due to the presence of condensed and the use of materials resistant to corrosion damages.
