The main objective of the PROBIOPOL project is the development of methodologies and tools to support the design and management of sustainable processes for the production of biodegradable polyhydroxyalcanoates (PHAs) biopolymers. PHAs are linear polyesters produced in nature by bacteria through aerobic fermentation of many carbon sources, completely biodegradable and biocompatible. PROBIOPOL project will develop a new, cost effective and environmental sustainable technology for isolating PHAs from bacteria mixed cultures by combining: a) innovative cells' pre-treatments and polymer purification's strategy by means of TiO2/UV or Ag0 nanostructured materials; b) polymer extraction through a green and safe system directly applicable to bacterial cultures, which combines the advantages of solvent extraction and these of dissolution of the non PHAs cellular matrix through surfactants; c) monitoring and control tools for process energy and efficiency management. Task 4.1 - "Plant Model" goal is to develop and the methodologies and apply them to build dynamic models of the plant. Such models will be used in Task 4.1 "Plant controller" to investigate the opportunity to develop model-based observers able to estimate, from the available feedback signals, crucial quantities (like bacteria mass and their activity, polymer concentration) that are not directly measurable. Additionally, the plant model from 4.1 can be used to investigate, by simulation, the plant behaviour, in order to optimize it for future releases, both for productivity and efficiency, taking into account also energetic performance. Deliverable 4.1 describes the proposed plant modelling approach. Chapter 2 describes the PHA production plant, including the sensors and actuators that have been chosen. Chapters 3 and 4 are dedicated to mathematical models that describe the thermal behavior of the plant and kinetics of the reactions taking place in the reactors. The dynamic response of the sensors will be also taken into account and is presented in chapter5, while chapter 6 depicts how the plant controller will be represented in the model, in order to reproduce and tune the adopted control strategy. The Matlab/Simulink© software will be used to develop a multi-domain model of the plant and to evaluate its behaviour.

Abstract
The main objective of the PROBIOPOL project is the development of methodologies and tools to support the design and management of sustainable processes for the production of biodegradable polyhydroxyalcanoates (PHAs) biopolymers. PHAs are linear polyesters produced in nature by bacteria through aerobic fermentation of many carbon sources, completely biodegradable and biocompatible. PROBIOPOL project will develop a new, cost effective and environmental sustainable technology for isolating PHAs from bacteria mixed cultures by combining: a) innovative cells' pre-treatments and polymer purification's strategy by means of TiO2/UV or Ag0 nanostructured materials; b) polymer extraction through a green and safe system directly applicable to bacterial cultures, which combines the advantages of solvent extraction and these of dissolution of the non PHAs cellular matrix through surfactants; c) monitoring and control tools for process energy and efficiency management. Task 4.1 - "Plant Model" goal is to develop and the methodologies and apply them to build dynamic models of the plant. Such models will be used in Task 4.1 "Plant controller" to investigate the opportunity to develop model-based observers able to estimate, from the available feedback signals, crucial quantities (like bacteria mass and their activity, polymer concentration) that are not directly measurable. Additionally, the plant model from 4.1 can be used to investigate, by simulation, the plant behaviour, in order to optimize it for future releases, both for productivity and efficiency, taking into account also energetic performance. Deliverable 4.1 describes the proposed plant modelling approach. Chapter 2 describes the PHA production plant, including the sensors and actuators that have been chosen.
