Bioprocess engineering stands as a cornerstone in the quest for developing sustainable packaging biomaterials, optimizing fermentation processes for the production of bioplastics from renewable feedstocks. This field is pivotal in ensuring efficient downstream processing for purification and exploring novel microbial strains or enzymes to enhance material properties. The overarching aim is to create packaging solutions that are biodegradable or compostable, thereby significantly reducing environmental impact [1].
Central to this endeavor is the critical role of microbial fermentation in the production of polyhydroxyalkanoates (PHAs), a promising family of biodegradable bioplastics. Strategies are being developed for metabolic engineering and process optimization to improve PHA yield and tailor material characteristics for a diverse range of packaging applications [2].
The exploration of novel enzymatic approaches for biopolymer modification is crucial for the development of advanced biomaterials destined for packaging. This research investigates specific enzymes capable of altering biopolymer properties, rendering them more suitable for particular packaging functions such as improved barrier properties or enhanced thermal stability [3].
Efficient recovery and purification of biopolymers from fermentation broths present significant challenges within bioprocess engineering. Current research focuses on developing cost-effective downstream processing techniques that yield high-purity biomaterials essential for food and other packaging applications [4].
Utilizing waste streams as feedstocks for bioplastic production represents a fundamental aspect of sustainability. This area examines the bioprocessing of lignocellulosic biomass and agricultural residues, transforming them into valuable packaging biomaterials through optimized fermentation and enzymatic treatments [5].
The development of active and intelligent packaging is an emerging frontier in material science. Research in this domain explores the incorporation of bioactive compounds into biopolymer matrices via bioprocessing techniques, aiming to extend the shelf-life and enhance the safety of packaged goods, thereby contributing to the reduction of food waste [6].
This study investigates the bioprocessing of chitin and chitosan, materials derived from crustacean waste, into films and coatings for sustainable packaging. The focus is on optimizing extraction and modification methods to achieve the desired mechanical and barrier properties necessary for advanced packaging solutions [7].
Scale-up challenges are a significant hurdle for the commercialization of biomaterials produced through bioprocessing. This paper addresses the optimization of bioreactor design and operating conditions for the large-scale production of biodegradable polymers, with the ultimate goal of achieving economic viability and a reduced environmental footprint [8].
Research is also exploring the use of fungal fermentation for the production of cellulose-based nanomaterials intended for packaging applications. This involves enzymatic pretreatment and controlled fermentation processes to yield high-quality cellulose nanocrystals possessing enhanced mechanical strength and biodegradability [9].
Life cycle assessment (LCA) is indispensable for rigorously evaluating the sustainability of bioprocessed packaging biomaterials. This study employs LCA to compare the environmental impacts of various bioplastic production pathways, offering insights for process optimization and informed material selection to support a circular economy [10].
