The dataset includes the tables concerning the experimental activity reported in the deliverable 3.3, the data produced includes more than one year of operation of the pilot plant platform, two main periods were considered here according to the progressive optimizations of the pilot plant platform. The description of the experimental periods is reported below: - the first experimental part during in which the whole mass balance of the system was studied in order to determine the feasibility of the process and the future perspectives in terms of scalability. - the second experimental period was dedicated to the optimization of the pilot plant so to achieve better yields in its different steps. Many components, such as pipes/pumps and valves, were changed in order to achieve better performance in the daily operations and better control of every single unit. Moreover, the PHA production step was put under automatic control so to optimise the single operations.
