The green circle™ is a circular economy IT platform that allows Optimal Renewable Gas customers to track how their organic waste and residues are transformed and re-introduced in the economy as renewable gas (biogas/biomethane) and organic nutrients (digestate).
Value added for companies joining Optimal Renewable Gas projects.

The green circle™ generated QR code helps to track:

  • organic waste provenance

  • renewable gas (biogas/biomethane) production

  • Fossil fuel displaced

  • digestate production

  • Net CO2(e) benefit of the waste/residue stream

A powerful marketing tool to show your customers sustainability and circular economy benefits of your organic waste and residues.
