Abstract Polyhydroxyalkanoates (PHAs) constitute a family of biopolymers. In recent times, this biodegradable material has gained a lot of attention due to its properties and its capability of being produced from renewable carbon sources based on agriculture or even on industrial wastes. The production of PHA is in a very early stage and is therefore subject of ongoing research. The company, AnoxKaldnes, is currently investigating the production of PHA from different industrial wastewater. The study presents a comparative life cycle assessment on a process system which treats wastewater from pulp and paper industry and simultaneously produces PHA (PHA production system), with respect to a reference system consisting of a conventional activated sludge treatment via mesophilic anaerobic digestion for biogas production (CH4 production system). The life cycle inventory analysis consisted of data collection and calculation procedure to quantify the total inputs and outputs of the systems covered in the study, hence mass- and energy balance at the level of unit process have been carried out. The PHA production system showed a daily production of 45.28 kg of PHA. In order to quantify the environmental impacts the EDIP1 method has been applied. The reference system presented slightly less environmental impacts than the PHA system. Finally it was concluded that investigation was needed in order to achieve an optimization of operation parameters in the PHA system.
