What is Biogas ?

Biogas is a mixture composed of approximately 55% methane (CH4) and 45% carbone dioxide (CO2).
It is produced through a process of organic material degradation  in the absence of oxygen,  called anaerobic digestion or methanization.

Produced from livestock manure, organic waste from industry and households, slaughterhouse waste, sewage sludge, as well as agriculture residues, biogas is a 100% renewable energy source.

In order to obtain biomethane, biogas has to be purified – mostly by removing the CO2 content – thus enabling it to have the same properties as natural gas and meeting grid operators’ specifications.

Biomethane usage
as a fuel for:

  • Heating
  • Industrial process
  • Mobility

Biogas in the
circular economy

A climate-positive solution to substitute natural gas

bGX has a long and rich expertise with markets and legal requirements of biogas. That’s why bGX is your trusted expert to help you substitute natural gas with waste produced biogas by choosing the suited quality products within its portfolio of production plants.

Since the beginning, bGX and partners take care of pre-desk audit, biomass process optimisation, setup qualification and required certifications of biogas plants.

Our chain of transparency goes from the substrates which are fed into the plants to the end deliveries to the clients.
Once biomethane has been fed into the network, guarantees of origins (GoOs) are created with options for mass balance delivery.

Our certified quality and environmental management systems ensure your delivery from the first order and thereafter. All documentation, including audits documents
and proof of sustainability are transferred from the producers to the customers.

Our services

bGX offers a multitude of services in the area of biogas and renewable fuels from non-food feedstock. bGX operates a portfolio of procurement of European biomethane GoOs in different countries such as Denmark, Germany, the Netherlands and the UK
as well as Switzerland. We make it a point of honour to
use only waste biogas from suppliers who fulfill
recognized standards.

bGX arranges physical deliveries through mass balance along with the delivery of the GoOs/certificates.

bGX assists biogas producers to acquire the best management through inventory and optimisation of the feedstock, reporting to the environmental agency and obtaining qualified certifications for premium quality biogas.

bGX advises its private and public clients on national and international standards, legal requirements together with required sustainability certificates. bGX supports your sustainable values.

bGX brings stakeholders together through roundtables, typically for the transportation sector (CNG/LBG) in an effort to exchange best practices for the promotion
of biogas.
