The dataset includes the pictures of the pilot plant platform for PHA production reported in the deliverable 3.3, the pictures are related to the description of the two experimental periods of the pilot plant platform. The pictures described the pilot plant platform during the first experimental period in which the feasibility of the process and the future perspectives in terms of scalability were determined and the second experimental period, dedicated to the optimization of the pilot plant so to achieve better yields in its different steps. The pictures highlight the change of many components such as pipes/pumps and valves, during the second period of the experimental activity to optimize the pilot plant efficiency.
