CleanMat, EarlyView.Efficient conversion of organic waste to biogas depends on the coordinated optimization of feedstock composition, pretreatment, operational parameters, reactor design, and microbial community dynamics. This review highlights how these interacting factors improve methane yield and process stability, advancing anaerobic digestion as a practical pathway ...

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 ...
