<i>Techno-economic Analysis on An Industrial-scale Production System of Biodegradable Plastics from Cheese By-products by Haloferax mediterranei</i>

Polyhydroxyalkanoates (PHA) are a family of biodegradable plastics used as an ecofriendly alternative for conventional plastics in various applications. In this study, an industrial-scale PHA production system was designed and analyzed for the material flows and economics with the use of SuperPro Designer. Haloferax mediterranei was utilized to produce poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV). Byproduct streams from a local cheese plant, with an input of 168.7 metric ton/day (MT/day) lactose, were used as the feedstock. Three scenarios with different processes for the treatments of used enzyme and spent medium were investigated and the major factors that influence the overall economics were identified. The simulated system produces 9700 MT/year PHBV with a yield of 0.2 g PHBV/g lactose and an overall process efficiency of 87%. The breakeven price was found to be more sensitive to the lactose price than enzyme price. The scenario with enzyme reuse and spent medium recycling achieved the lowest breakeven price among others, which can be less than 4 $/kg PHA based on the delactosed permeate (DLP) unit price. The study suggests utilizing dairy derived feedstocks has the potential to make PHA competitive in the bioplastic market, which could be beneficial to both dairy and bioplastic industries.

Insect meal (IM) is a source of high-quality protein for aquafeed while insect oil (IO) is a source of fatty acids used in monogastric feed with identical or better performance than premium fishmeal (FM) or vegetable oils (VOs) respectively. Although insects’ ability to feed on agricultural by-products and the entire valorization of insect products (IM, IO, frass) suggest insect production is sustainable, no studies have documented its environmental impact using industrial-scale production data. The present study is the first attributional life cycle assessment (A-LCA) based on data from an industrial-scale facility implementing an innovative symbiosis production model. This A-LCA was used to (i) assess the environmental performance of the symbiosis model vs. a no-symbiosis model and (ii) compare the environmental impacts of IM and IO production vs. their respective alternatives. The results revealed that the symbiosis model introduces a meaningful change in terms of environmental footprint by reducing CO2 emissions by 80% and fossil resources depletion by 83% compared to the no-symbiosis model. The higher sustainability of the IM and IO produced using the symbiosis model was also demonstrated, as CO2 emissions were reduced by at least 55% and 83% when compared to the best FM and VOs alternatives, respectively.

Evidence for industrial scale production of numerous manufacturing processes has been attested in all phases of occupation at Poggio Civitate (Murlo). A subset of these, tools for the production of textiles and fibers, indicates that textile crafts were manufactured on a large scale as a part of a centralized and organized industry. These industrialized practices occurred within and around the monumental seventh and sixth century BCE complexes which displayed architectural decoration bearing iconographic themes that served to secure the positions of the aristocratic elites. This paper investigates the stamped decoration present on rocchetti and its relationship to the architectural decoration present on the monumental structures of the site. As small moveable objects used by members of the community, rocchetti present an opportunity to investigate the movement of elite images through the non-elite population of a community and their reception of aristocratic ideology presented in monumental structures.
