Grain and beer production by-products (wheat bran, grain production residues and Saccharomyces cerevisiae) application in compostable packaging material. The impact on physical-mechanical and barrier properties
This study developed compostable paper packaging coated with bio-based barrier materials made from grain and brewery by-products, as an alternative to conventional petroleum-based polymer coatings that make paper packaging non-recyclable. The bio-coated paper maintained food protection properties while remaining compatible with biological waste treatment.
Biodegradable Fiber-Reinforced Gluten Biocomposites for Replacement of Fossil-Based Plastics
Researchers created biodegradable biocomposites from wheat gluten reinforced with carbon fibers as an alternative to fossil-based plastics that shed microplastics. The materials could be processed using standard industrial plastic manufacturing equipment, achieved strength two to four times greater than unreinforced protein-based materials, and were confirmed to break down into environmentally harmless molecules. This demonstrates a viable path toward high-performance plastics that do not contribute to microplastic pollution.
