Carbon emission assessment of tunnel infrastructures: From construction to operation

Deep Underground Science and Engineering, EarlyView.
This study develops a lifecycle carbon accounting framework for tunnel infrastructures, covering design, construction, operation, maintenance, and dismantling. Applied to a subsea tunnel case, the framework reveals the carbon emission distribution among four typical tunnel types and highlights potential carbon offset methods for low‐carbon tunnel ...

High‐strength composites by thiocracking of high‐polypropylene‐content mixed waste

Polymer International, EarlyView.
Mixed plastic waste made up of polystyrene and polypropylene was reacted with elemental sulfur to give high‐strength composites. Abstract Mixed‐material municipal waste poses a persistent end‐of‐life management challenge because the heterogeneous composition limits efficient separation and recycling. After disposal, mixed‐material waste often fragments
