ClearStudy of structure and properties of biodegradable composite films based on thermoplastic starch
Researchers studied the structure and properties of biodegradable thermoplastic starch composites as potential replacements for conventional polyethylene plastics. Using starch — a natural, renewable polymer — as a filler in plastic films could reduce microplastic pollution by enabling faster environmental breakdown.
A Review on Biopolymer-Based Biodegradable Film for Food Packaging: Trends over the Last Decade and Future Research
This systematic review explores biodegradable packaging made from natural materials like starch and proteins as alternatives to conventional plastics. Reducing plastic packaging is important because traditional plastics break down into microplastics that contaminate food and the environment.
Bio-nanocomposites films based on unmodified and modified thermoplastic starch reinforced with chemically modified nanoclays
Researchers developed biodegradable bio-nanocomposite films by combining chemically modified thermoplastic starch with functionalized nanoclays via reactive extrusion, demonstrating that both strategies synergistically reduce water sensitivity and improve mechanical and barrier properties — offering a pathway toward more stable, sustainable packaging materials that degrade without generating persistent plastic waste.
Recent Preparations and Innovations in the Biodegradable Bioplastics and Biocomposites (A Review)
This review covered recent advances in biodegradable bioplastics and biocomposites as alternatives to petroleum-based plastics, including their preparation methods, properties, and environmental performance. The authors noted that while bioplastics reduce reliance on fossil fuels and potentially decrease microplastic persistence, production costs and performance limitations remain barriers.
Environmental Properties of Coconut Fiber/Reinforced Thermoplastic Starch/Beeswax Hybrid Composites
This study developed biodegradable composite materials from thermoplastic starch, beeswax, and coconut fiber as an alternative to conventional plastic. Bio-based composites that replace petroleum-derived plastics help reduce the sources of microplastic pollution in soil and water.
Plastic Alternatives: Biodegradable Solutions and Their Real-World Impact
This review examines biodegradable alternatives to conventional plastics, evaluating biopolymers such as polylactic acid, polyhydroxyalkanoates, and starch-based composites for their practical performance, cost-efficiency, and real-world environmental impact as substitutes for petroleum-based plastic packaging.
Biodegradable Packaging Materials for Foods Preservation: Sources, Advantages, Limitations, and Future Perspectives
This review examines biodegradable packaging materials derived from natural sources as alternatives to conventional petroleum-based plastics for food preservation. Researchers found that materials made from polysaccharides, proteins, and lipids can effectively extend food shelf life while being more environmentally friendly. The study acknowledges that cost and performance limitations remain, but highlights recent advances in combining these natural materials with antimicrobial and antioxidant agents to improve their practical viability.
Obtaining and Characterizing New Types of Materials Based on Low-Density Polyethylene and Thermoplastic Starch
Researchers developed and characterized new polymer blends made from low-density polyethylene and thermoplastic starch, aiming to create more sustainable and recyclable materials. The study found that incorporating thermoplastic starch changed the mechanical and thermal properties of the blends. Evidence indicates that these LDPE-starch composites could serve as a step toward reducing reliance on purely petroleum-based plastics in packaging and other applications.
Current trends in biopolymers for food packaging: a review
This review covers the latest developments in biopolymer-based food packaging, including biodegradable films, edible coatings, and active or smart packaging systems. Researchers found that while these sustainable alternatives show promise, they still face challenges in matching the moisture, heat, and barrier properties of conventional petroleum-based plastics. The study highlights ongoing efforts to improve these materials so they can realistically replace traditional plastic packaging.
Existing Scenario and Environmental Significance of Biodegradable Plastics: A Review for a Sustainable Future
This review examines the current status of biodegradable plastics derived from renewable sources (starch, PLA, PHA), covering production methods, degradation behavior, and their real-world performance as alternatives to petroleum-based plastics in reducing landfill burden and marine microplastic pollution.
Development of Technology for Obtaining a Biodegradable Polymer
Researchers developed biodegradable polymers made from starch combined with organic acids and plasticizers as a sustainable alternative to conventional plastics. The resulting bioplastics passed physicochemical tests and are described as ready for mass production.
Introduction to Starch-Based Bioplastics
This review introduces starch-based bioplastics as a sustainable alternative to conventional fossil fuel-derived plastics, examining the composition and properties of starch polymers. The study discusses how starch-based materials could help address microplastic pollution concerns associated with traditional plastics, though challenges remain in improving their mechanical strength and moisture resistance.
A review of advancements in chitosan-essential oil composite films: Better and sustainable food preservation with biodegradable packaging
This review covers how films made from chitosan (a natural material from shellfish) combined with essential oils are being developed as biodegradable food packaging to replace conventional plastics. By reducing reliance on plastic packaging, these alternatives could help decrease the amount of microplastics that migrate into food and are ultimately consumed by people.
Materials
This paper reviews advances in nanocomposite and biopolymer-based food packaging materials, noting that microplastic pollution has been detected globally and is a recognized threat to ecosystem and human health. It briefly contextualises microplastics as a motivation for developing biodegradable packaging alternatives, though the primary focus is materials science rather than microplastics research per se.
Benefits and Drawbacks of Bioplastic as an Alternative of Conventional Plastic towards Sustainable Plastic T
This review examines bioplastics derived from renewable biomass sources (such as corn starch, vegetable oils, and food waste) as sustainable alternatives to conventional petroleum-based plastics, evaluating their benefits and drawbacks across environmental performance, biodegradability, and scalability. The article explores whether bioplastics represent a viable pathway toward more sustainable plastic use given growing concerns over the non-biodegradable nature and resource intensity of conventional plastics.
