Data‐Driven Analysis of Green Logistics Strategies for the Logistics and Transportation Companies: A Bipolar Fuzzy Methodology

Business Strategy and the Environment, EarlyView.
ABSTRACT Global imperatives, such as climate change, environmental concerns, and carbon emissions, make green transformation an inevitability in the logistics sector. Green logistics strategy formulation is an economic choice problem, but it also turns out to be a multicriteria decision‐making (MCDM) process that encompasses the triple bottom line (TBL)

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 ...

Surfactant Enhanced Bioremediation of Saline Diesel Contaminated Water by a Novel Bacterial Halophilic Consortium

Journal of Surfactants and Detergents, EarlyView.
ABSTRACT The use of microorganisms is an evolving method for the degradation of hydrocarbon contaminants. In this aim, halophilic hydrocarbon degrading bacteria were isolated from oil contaminated soil in Tunisia. A lipopeptide biosurfactant produced by Bacillus subtilis SPB1 was tested to increase diesel biodegradation along with co‐inoculation with ...
