Ibrida Birra is an organisation that produces locally branded beer made from unsold bread through partnerships with a network of neighbourhood bakeries and with a local brewery in Milan. The branded beer is then sold in the neighbourhood. This is the context of the PrimaSeconda scenario, in which ReflowOS tools are used to create a customized web application (PrimaSeconda for Ibrida Birra) to manage the steps of the process and to facilitate the job for the “orchestrator” of the process (Ibrida Birra Team).


The goal is to give value to the use of food surplus and its transformation through:

The prototype

PrimaSeconda supports organizations (SMEs, start-ups, NGOs) that claim to have a closed circular loop but do not have technical tools to track/trace or prove that. PrimaSeconda monitors material flows, therefore it can certify that particular processes are circular and it can “quantify” the circular loops, thereby showing their value.

The web app lets the organization manage the process of transformation. The flow of the circular value chain needs to be modelled beforehand through a high-level description diagram, using Miro or other flow chart tools.  

The pilot case can be summarised in these steps (in brackets the Ibrida Birra case):  

The agents are:

The web app serves the needs of the Flow Orchestrator during Flow Operation. With this app, a user can:  

The web app is an operation user interface that works utilizing the ReflowOS API.  

The Value Flows model is specified using GraphQL based on a detailed REA model, which has been described at a higher level with graphics tools (as discussed above).

Through the app, the users can update the status of the various resources in the value chain.  

When a production process is finished, the user can analyse the collected data (i.e., how many kg of resources are collected, how many of them are discarded, how many are effectively up-cycled in a “reflow”). In this way, the production batch steps can create a system that creates accountability for the initiatives (i.e., by demonstrating that in a certain period a certain amount of circular resources are produced) and can serve as a tracing system for customers who wants to verify the provenance of the product.

PrimaSeconda makes APIs calls to ReflowOS with i.e. the following data:

ReflowOS stores these data and returns two main outputs to PrimaSeconda:
