The Effect of Nozzle Temperature, Infill Geometry, Layer Height and Fan Speed on Roughness Surface in PETG Filament

Journal of Mechanical Engineering Science and Technology, 2022
3D printing is a process of making three-dimensional solid objects from a digital file process created by laying down successive layers of material until the object is created. Many filaments can be used in 3D printing, one of which is PETG (PolyEthylene

Performance Evaluation of Compression‐Molded Recycled Mixed Plastic Fractions From Light Packaging

Polymer Engineering &Science, EarlyView.
Mixed HDPE/PP bottle‐cap waste was successfully processed through closed‐loop mechanical recycling. The recycled blends maintained stable thermal, rheological, and mechanical performance over multiple cycles, demonstrating the feasibility of valorizing heterogeneous polyolefin waste without advanced polymer separation.

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 ...
