Impact of Packaging and Recycling Systems on Material Recirculation: A Stage‐Decomposition Model

Packaging Technology and Science, EarlyView.
A system‐level view emerges from decomposing recycling into four stages (participation, collection, sorting and process yield), diagnosing constraints and targeting interventions. Cumulative equivalent uses (CEUs) quantify long‐term retention, revealing marginal improvements at high baselines generate disproportionately larger gains than low‐baseline ...

3D printed polyethylene terephthalate glycol ternary composites with short carbon fiber/ carbon nanotube graphitic reinforcements: Insights into multi-scale synergistic mechanisms

Composites Part C: Open Access
Three-dimensional printed (3DP) Polyethylene Terephthalate Glycol (PETG) ternary composites reinforced with short carbon fibers (sCF) and multi-walled carbon nanotubes (CNT) are reported for the first time. A single-screw extrusion process is employed to

Chemical Recycling as a Tool for Enabling a Second Life for Polyesters

SusMat, EarlyView.
This review presents the elucidation of the life cycle of main polyesters, detailing end‐of‐life methods, with focus of solvolysis technologies, then an analysis of LCA and TEA on literature data, an original data analytic, and, finally, a current industrial mapping of the main processes with a critical perspective on the plastic life‐cycle ecosystem ...

Study of the Thermal and Hydrothermal Aging Effects on the Properties of 3D‐Printed Thermoplastic Polyurethane

Journal of Vinyl and Additive Technology, EarlyView.
Effect of post‐aging conditions on mechanical and thermal properties of FDM‐printed parts. ABSTRACT In this study, the thermal and hydrothermal aging of TPU produced with the FDM technique was simulated and subjected to a series of tests. The alterations in the internal structures of the samples that had been subjected to tensile, hardness, adhesive ...

Assessment of Different Technologies in the Fabrication of 3D Printed Tooth Models for Dental Education

European Journal of Dental Education, EarlyView.
ABSTRACT Background 3D printing has emerged as a practical method for fabricating customisable, accurate and affordable dental training models. Numerous 3D printing technologies exist, though there is no standardised comparison to inform their implementation in dental education.

Some thermodynamic and kinetic properties of the system PETG‐CO₂, and morphological characteristics of the CO₂‐blown PETG foams

Polymer Engineering & Science, 1999
AbstractThe solubility of CO2 in PETG, a glycol‐modified PET, was measured at different temperatures and over a broad pressure range, and diffusion coefficients were derived at the corresponding conditions. The solubility of CO2 is quits high. For example, almost 15 wt% CO2 can be dissolved in PETG at 35°C and 6.0 MPa. Consequently, CO2 is good blowing
