The overall concept is to track and record the GHG, CO2, and other related polluting gas, emission, consumption, and savings in parallel biogas production by a biogas plant. Based on savings, a corresponding number of credit tokens will be created and awarded to the biogas producer. A third party interested in offsetting its emission can connect to the solution and request to buy (or swap against other activities) some credit tokens that will be delivered together with a proof of origin of the compensation activities. The original owner of the credit tokens will receive a payment or an equivalent compensation (e.g., a service or the supply of material).
Following further investigations of the ecosystem and our discussions with several stakeholders, we consolidated the concept by extending it toward a comprehensive view that integrates all the supply chains in the biogas production process. The idea now considers the source of the material (e.g., feedstock, organic waste) used for biogas production and estimates the amount of emission or savings depending on both the source and the biogas production processes. By comparing the generated gas emissions with or without using the primary source in biogas production, we can assess the savings vs. the costs without biogas production. This will also highlight further the difference between using waste vs feedstock. Then during the biogas production process, some non-biogas gas may also be filtered and separated for being reused in other industries. This will also account for specific savings. This improved concept enables, in addition, distribution rewards to the savings parties along the supply chain.
Note that at this stage, all savings/costs are mainly based on general estimation, but it is foreseen to rely on the existing probes in the system to measure them when possible.
Finally, additional features related to data sharing and auditing capabilities will be planned in the future. It was emphasized the value of allowing additional stakeholders (e.g. auditors) to use the solution, as will benefit from the information collected by the solution.
