Defining Remanufacturing: A Key Business Strategy Advancing Industrial Circularity

Business Strategy and the Environment, EarlyView.
ABSTRACT Remanufacturing is a key strategy in the circular economy, enabling substantial product value retention. However, inconsistent definitions across standards and legislation hinder global trade, core recovery and market acceptance. This study examines how remanufacturing is defined in laws and standards, and how these definitions impact industry

A predictive model of energy savings from top of rail friction control

, 2014
In this paper the authors present a predictive model of train energy requirements due to the application of a top of rail friction modifier (TOR-FM) versus dry wheel / rail conditions. Using the VAMPIRE® Pro simulation package, train energy requirements

Influence of high-frequency vibration-absorbing fasteners on suppressing localized rail bending modal vibration

Railway Engineering Science
Since the view that the localized rail third-order bending mode can cause high-order polygonization (mainly 18–23) of high-speed train wheels was put forward in 2017, many scholars have attempted to link a connection between the localized rail bending ...

Sustainability‐Oriented Collaborations in Green Energy Markets Formation: A Configurational Analysis of Alliance Management Capabilities and Relational View

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Sustainability‐oriented collaborations are inter‐organisational arrangements where the competencies of multiple companies are pooled together to tackle environmental challenges. These collaborations differ from traditional strategic alliances in that they tackle complex goals amidst greater uncertainties that extend beyond economic performance,

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 ...

Collective Decision‐Making and Institutional Configurations in Polycentric Environmental Governance

Environmental Policy and Governance, EarlyView.
ABSTRACT Why do formally similar multi‐level governance arrangements produce different governance outcomes in urban climate and transport policy? This article examines variation in governance performance across three metropolitan regions in Norway operating under the national Urban Growth Agreement (UGA) framework and pursuing the shared objective of ...
