Project description: (the following text is taken from the website of the joint project)
Molded fiber packaging (MFP), made from natural fibers, has a wide range of applications. However, for direct food contact, virgin fibers, mainly high-quality bleached cellulose fibers from wood or bagasse, are traditionally relied upon. The challenge is to integrate functional barriers such as grease-repellent layers, which are usually achieved using additives made from fossil raw materials, which impairs the recyclability of the packaging. This research project pursues an innovative approach that aims to utilize plant residues from agriculture both as a fiber raw material and as a biogenic additive. Specially treated, highly fibrillated fibers can serve as an effective barrier against fat and oxygen. However, the dewatering and drying processes for this fiber layer require considerable effort and energy, which impairs the productivity of the molded fiber process. In addition to optimizing the pulping processes, the project focuses on the development of a spray application for these fibers on a preformed porous fiber network. The project aims to develop a process chain that allows lignocellulosic non-wood fibers (preferably from agricultural residues) to be specifically prepared in two process stages so that they provide both fiber material for the molded fiber body and the fiber matrix for the biogenic barrier. This innovation aims to simplify the application of fiber-based barrier materials from different waste streams while ensuring a balance between protective function, recyclability and a favorable environmental balance (e.g. low ecotoxicity) according to a life cycle analysis (LCA). The sub-project focuses on the life cycle analysis (LCA) of raw materials and cast fiber products as well as on the evaluation of the process chain including material flow cost accounting (MFCA).
