ClearPET foaming: development of a new class of rheological additives for improved processability
This paper describes development of rheological additives to improve PET foaming for lightweight packaging, as an alternative to hard-to-recycle foamed polystyrene. Replacing polystyrene foam with more recyclable materials is important for reducing ocean microplastic pollution from packaging waste.
Polymer Bead Foams: A Review on Foam Preparation, Molding, and Interbead Bonding Mechanism
This paper is not directly about microplastics; it provides a comprehensive review of polymer bead foam materials — including preparation, molding techniques, and inter-bead bonding — with applications in packaging, automotive parts, and insulation.
Environmental implications of styrofoam waste and its utilization as lightweight fill material for embankment construction
Researchers investigated the environmental problems caused by styrofoam waste and explored whether it could be repurposed as a lightweight fill material for construction embankments. They found that incorporating styrofoam into embankment construction improved structural performance while diverting waste from landfills. The study suggests that reusing styrofoam in civil engineering could help address both waste management and construction challenges.
Expandable polystyrene production and market survey- A review
This review examines the production processes and global market for expandable polystyrene (EPS), describing the two main manufacturing approaches — batch processing and the impregnation method — used to produce pre-expanded PS beads. The paper surveys EPS applications in packaging, construction, and insulation and presents data on worldwide polystyrene consumption and market trends.
Lightweight carbon foam obtained from post-use polyethylene terephthalate bottles, properties, and potential applications
Researchers synthesized lightweight carbon foam from post-consumer PET plastic bottles via a controlled carbonization process, characterizing the foam's physical and chemical properties and exploring its potential as a value-added material from plastic waste recycling.
Energy absorption and resilience in quasi-static loading of foam-formed cellulose fibre materials
Researchers investigated lightweight foam-formed cellulose fibre materials as potential replacements for fossil-based plastic cushioning in packaging applications. They tested a wide range of material compositions and densities, finding that fibre type and refining significantly influenced energy absorption and resilience during compression. The study demonstrates that cellulose-based foams could provide adequate mechanical protection for packaging while avoiding the microplastic pollution associated with conventional plastic foams.
A mini-review on expanded polystyrene waste recycling and its applications
This mini-review summarizes recycling technologies and emerging applications for expanded polystyrene waste, examining mechanical, chemical, and dissolution recycling methods and their practical feasibility for diverting EPS from landfill in both developed and developing countries.
Expanded beads of polyethylene moldable at low steam pressure
Researchers developed an expanded polyethylene bead foam that can be molded at very low steam pressures, making it cheaper and more flexible to manufacture than conventional expanded polystyrene (Styrofoam). Unlike polystyrene, polyethylene foam is more readily recyclable and the study explicitly notes this approach avoids contributing to microplastic pollution. This represents a step toward replacing one of the most environmentally persistent foam plastics with a more manageable alternative.
Research Progress in the Preparation of Aluminum Foam Composite Structures
This review summarizes advances in aluminum foam composite structures, covering fabrication methods and the combination of lightweight properties with functions such as energy absorption, sound insulation, and electromagnetic shielding for structural and functional applications.
Preparation and Study of a Waste Corrugated Cardboard Fiber‐Based Foamed Material With Good Hydrophobicity and Flame‐Retardant Properties
Researchers fabricated biomass foams from waste corrugated cardboard fibres using a microwave-assisted foaming technique, investigating the synergistic effects of silane fibre modification and kaolin doping on mechanical, hydrophobic, and flame-retardant properties. The optimised foam achieved a compressive stress of 0.53 MPa at 50% strain, a 20.1% reduction in water absorption, and a 34.7% increase in limiting oxygen index compared to conventional foams, presenting a sustainable alternative to petroleum-based cushioning materials.
Energy Absorption and Resilience in Quasi-Static Loading of Foam-Formed Cellulose Fibre Materials
Researchers investigated foam-formed cellulose fibre materials as biodegradable replacements for fossil-based plastic cushioning in packaging, testing 129 trial formulations with densities from 21 to 123 kg per cubic meter to characterize quasi-static energy absorption and mechanical resilience properties.
Polyurethane Foam Waste Upcycling into an Efficient and Low Pollutant Gasification Syngas
Researchers modeled the gasification of polyurethane foam waste under various conditions, finding that optimized thermochemical treatment can convert this common polymer waste into hydrogen-rich syngas with low pollutant output, offering a viable energy recovery pathway for difficult-to-recycle plastic foam materials.
