heal.abstract	From industrial facilities to households, a vast amount of waste is generated every year at an alarmingly higher rate. Nowadays, the amount of global waste is on the rise creating a chatter amongst the academic and industrial community as to what measures could be taken to possibly address this phenomenon. Mismanaged or untreated waste imposes a dramatic impact on ecosystems, climate change and consequently on human health. Waste cooking oils have great potential as raw materials for industrial high-value products such as bioplastics and biodiesel. Today, advances in technology allow the utilization and valorization of such cooking oils using different kinds of processes. Frying oils can be treated with saponification to produce soaps for dishwashing purposes, while purification methods of valorization of such oils could lead to plasticizers, bio-lubricants, polymers or even biodiesel. This study illustrates a novel WCO valorization chemistry for the production of added-valued bioplastics. The core process is based on bio-based catalysis, in which E.Coli is fermented to produce oleate hydratase enzyme, which catalyzes the conversion of FFAs into the key building block of 10- Hydroxystearic-Acid (10-HA). The core process is further integrated with upstream saponificationacidification stages for the pre-treatment of mixed WCOs, while downstream chemical processes (hydrogenation, esterification, polymerization) are upgrading the 10-HA building block into bio-based poly-10-HAME polymer. A Techno-Economic Analysis is necessary to ensure the viability of the proposed biorefinery plant conceptual design, by calculating the capital and operational expenditures. The sustainability of this novel chemical approach is provided by employing energy integration and Life Cycle Assessment practices to further establish a decrease in the overall energy consumption and a more environmentally friendly approach respectively.	en
