ClearLow-Quality Coffee Beans Used as a Novel Biomass Source of Cellulose Nanocrystals: Extraction and Application in Sustainable Packaging
Researchers developed bio-based methylcellulose films reinforced with cellulose nanocrystals (CNCs) extracted from low-quality coffee beans as a sustainable alternative to petroleum-based plastic food packaging. The extracted CNCs showed needle-like morphology (~221 nm length), 65.75% crystallinity, and good thermal stability, providing a promising path to reduce microplastic accumulation in food chains.

EFSA Project on the use of New Approach Methodologies (NAMs) for the hazard assessment of nanofibres. Lot 1, nanocellulose oral exposure: gastrointestinal digestion, nanofibres uptake and local effects
Researchers used new approach methodologies to assess the potential hazards of nanocellulose materials when consumed orally, focusing on intestinal barrier crossing, local tissue effects, and microbiome interactions. They found that nanocellulose particles were taken up by intestinal cells and that repeated exposure increased uptake, though most effects on gut tissue were mild. The study provides safety-relevant data for the growing use of nanocellulose in food industry applications.
Assessment of the cytotoxicity micro- and nano-plastic on human intestinal Caco-2 cells and the protective effects of catechin.

Food packaging characterization, composition profiles and in vitro testing of micro(bio)plastics from selected petroleum- and plant-based food containers
Researchers tested the composition and cytotoxicity of microplastics from both petroleum-based and plant-based food packaging materials using intestinal cell models. The study found that some products marketed as bio-based actually contained synthetic polypropylene with plant fiber additives, and while no acute toxicity was observed, petroleum-based microplastics induced cellular stress whereas plant-based particles showed potential protective effects against oxidative damage.
Renewable cellulosic nanocomposites for food packaging to avoid fossil fuel plastic pollution: a review
Researchers reviewed how cellulose nanoparticles extracted from plant biomass can replace petroleum-based plastics in food packaging, finding that adding just 1–5% cellulose nanoparticles significantly improves strength, reduces oxygen and water vapor permeability, and keeps packaging biodegradable. The review positions cellulose nanocomposites as a scalable, eco-friendly alternative to fossil-fuel plastics that contribute to microplastic pollution.
