Bio-based films have become good alternatives to petrochemical-based films for single-use applications owing to increased environmental awareness and the search for sustainable products.
However, providing novel bio-based films with reduced environmental impacts compared with
fossil-based films requires ecodesign in the early product research, development, and innovation
(RDI) stages. This review investigates the main challenges in the ecodesign of bio-based films and
provides recommendations for overcoming them in early RDI. We identified the main materials,
production techniques, and properties of bio-based films for food packaging, which are important
for identifying product functionality and performance and selecting appropriate inventories. We
then review the life cycle assessments (LCA) of bio-based films and biopolymers to analyze the
modeling choices and impacts. Considering the vast literature on film formulations and properties, we found only a few published environmental assessments of bio-based films. The reviewed
studies focused on evaluating commercially available biopolymers by applying a conventional
cradle-to-gate life cycle assessment to select optimal formulations for a new packaging solution.
Most assessments relied only on laboratory data to calculate impacts and compared novel biopolymers with existing (mainly fossil-based) ones, disregarding the best practices for ex-ante LCA.
Major challenges in early film RDI include the lack of knowledge of film effects on packed food,
unclear definition of functionality, the use of novel bio-based compounds in film formulations,
hardening inventory development, and increasing uncertainty in impact assessment. We provide
recommendations for overcoming these and other challenges. MenosBio-based films have become good alternatives to petrochemical-based films for single-use applications owing to increased environmental awareness and the search for sustainable products.

The development of the extraradical mycelium and auxiliary cells and spore production of Scutellospora reticulata in association with Ri-DNA transformed carrot was followed under root-organ culture conditions. Extraradical mycelium development followed classical lag-exponential-plateau phases, with an additional late decline phase en number of auxiliary cells. Spore production started in parallel with a critical extraradical mycelium biomass produced, continued long after root growth ceased and during the late decline in auxiliary cells were shown to exhibit hyphal re-growth, but not root colonization, either in situ or in vitro. These results showed that root and extraradical mycelium development were intimately associated in a sequence where both grew together during active root growth, followed during root aging by a period in which only the fungus developed. Spore production appeared dependent on a critical extraradical mycelium biomass on the re-allocation of resources from both the intraradical mycelium and the auxiliary cells via the hyphal network. |
