Redistributed manufacturing (RdM) is an emerging paradigm that emphasises localised production to enhance responsiveness, customization, and resource efficiency. This paper examines the environmental sustainability of RdM, in particular the factory-in-a-box (FiaB) production paradigm utilizing life cycle assessment (LCA). FiaB is a form of redistributed manufacturing where production takes place in movable units. FiaB has many perceived benefits when compared to conventional production, manifest in shorter, more responsive, and possibly more sustainablesupply chains. A comparative case study on an existing FiaB prototype in the farms produce packaging industry is carried out to evaluate the environmental impact of adopting a FiaB paradigm against centralised packaging. Results indicate lower environmental impact of the FiaB scenario (39.4 against 185 kgCO2e per functional unit), mainly due to lower transportation-related emissions. This research contributes to advancing sustainable manufacturing by demonstrating the environmental benefits of FiaB in comparison with the conventional (centralised) production in certain contexts.
