Utilization of spent coffee grounds as fillers to prepare polypropylene composites for food packaging applications
Researchers used waste coffee grounds as filler material in polypropylene plastic composites to improve sustainability and reduce reliance on virgin plastic. Adding natural biomass waste to plastic formulations can reduce the total plastic content in consumer products, though the composites still produce microplastic fragments during use.
Low-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.
A Systemic View of Biodegradable Materials: Analyzing the Environmental Performance of Compostable Coffee Capsules in Real Infrastructural Contexts
A systemic analysis of biodegradable materials examined their environmental performance across their full lifecycle, from production through disposal and degradation. The review finds that the environmental benefits of biodegradable plastics depend heavily on end-of-life conditions and that many do not degrade as claimed under real-world conditions.
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.

Valorization of Cork Stoppers, Coffee-Grounds and Walnut Shells in the Development and Characterization of Pectin-Based Composite Films: Physical, Barrier, Antioxidant, Genotoxic, and Biodegradation Properties
Researchers developed biodegradable composite films using pectin combined with waste materials from cork stoppers, coffee grounds, and walnut shells as a sustainable alternative to plastic packaging. The films showed antioxidant properties, were non-genotoxic, and biodegraded effectively in both soil and seawater within weeks. The study demonstrates that food industry and agricultural waste can be repurposed into functional, environmentally friendly packaging materials.
The Potential of Spent Coffee Grounds in Functional Food Development
This review explores whether spent coffee grounds, the leftover material after brewing coffee, could be used as a health-promoting food ingredient rather than being thrown away. Spent coffee grounds contain beneficial compounds like caffeine and antioxidants that may help protect against heart disease, cancer, and liver problems. While not directly about microplastics, repurposing this waste could reduce the millions of tons of coffee grounds sent to landfills each year, where they contribute to environmental pollution.
Desarrollo de biopelículas degradables a partir de harina de fruta de pan (Artocarpus altilis), como alternativa al uso de plásticos sintéticos convencionales
Biodegradable biofilms were developed from breadfruit flour (Artocarpus altilis) as a sustainable alternative to conventional synthetic plastic packaging. The biofilms were characterized for physical, mechanical, and barrier properties, offering a compostable food packaging material that reduces microplastic waste.
Biocomposites Based on Wheat Flour with Urea-Based Eutectic Plasticizer and Spent Coffee Grounds: Preparation, Physicochemical Characterization, and Study of Their Influence on Plant Growth
Researchers developed biocomposite materials from wheat flour plasticized with a choline chloride-urea eutectic mixture and spent coffee grounds, finding that the resulting material supports plant growth and offers a biodegradable alternative to synthetic plastic packaging.
Revalorization of Yerba Mate Residues: Biopolymers-Based Films of Dual Wettability as Potential Mulching Materials
This is not about microplastics — it is a materials science study developing biodegradable mulching films from Yerba Mate agricultural residues, cellulose nanofibers, chitosan, and polylactic acid, aimed at replacing conventional plastic mulch films with a compostable alternative.
An overview: exploring the potential of fruit and vegetable waste and by-products in food biodegradable packaging
Researchers reviewed how fruit and vegetable processing waste — rich in polyphenols, vitamins, and fiber — can be transformed into biodegradable food packaging films and coatings, offering an eco-friendly alternative to conventional plastic packaging. Repurposing food waste this way could simultaneously reduce plastic pollution (including microplastics from packaging degradation) and address agricultural waste disposal challenges.
