1000 Sm3/h

Case History
AF Bioenergie

An innovative and efficient plant realised by IES BIOGAS, fed by agro-industrial biomass (waste and by-products of the dairy industry) for the production of biomethane.

Made in Italy, perfectly integrated in the company’s production cycle it’s capable of feeding up to 1000 Sm3 per hour of advanced biomethane to the national gas network and over 7600 vehicles per year.

Without waste and without odours, in favour of the environment and the community.

The future is biomethane

Biomethane is a biogas derived gas, which has undergone a refining and purification process, called upgrading, whose concentration of CH4 exceeds 98%. It has characteristics and conditions of use corresponding to those of methane gas and is suitable for feeding the natural gas network.

The biogas, desulphurised and dehumidified, undergoes a purification process, in order to separate the methane from the other gases that make up the biogas mixture. The biomethane obtained can be used, marketed and transported, in gaseous or liquefied form, in the same way as natural gas.The advantages biomethane

  • Programmable renewable source
  • Reduction of import dependency
  • Development of the local economy
  • Environmental sustainability
  • Perfect example of circular economy
  • Reduction of the emissions and greenhouse effect
  • Maximum flexibility
