Corrosion and Process Analysis of a Preoxidized MgO Recyclate‐Based Cermet Anode in Laboratory‐Scale Na‐Cryolite Molten Salt Electrolysis of Aluminum at 1000°C

open access: yesAdvanced Engineering Materials, EarlyView.
EDX elemental map of the pre‐oxidized MgO–steel cermet anode cross section after electrolysis. The development of inert anodes for aluminum electrolysis remains challenging due to the high corrosivity of cryolite‐based melts at 950°C–1000°C. This study investigates the corrosion and process behavior of a carbon‐free MgO–steel cermet anode derived from ...

Decarbonizing Near-Zero-Energy Buildings to Zero-Emission Buildings: A Holistic Life Cycle Approach to Minimize Embodied and Operational Emissions Through Circular Economy Strategies

open access: yesApplied Sciences
The decarbonization of the building sector is essential to mitigate climate change, aligning with the EU’s Energy Performance of Buildings Directive (EPBD) and the transition from near-Zero-Energy Buildings (nZEBs) to Zero-Emission Buildings (ZEBs). This

The evaluation of national accounting matrices with environmental accounts (NAMEA) as a methodology for carrying out a sustainability assessment of the Scottish food and drink sector [PDF]

open access: yes, 2009
This report introduces environmental input-output (IO) accounts for Scotland as an example of a NAMEA framework. It provides an introduction to the use of basic IO multiplier methodology, which can be applied to examine pollution/waste generation and/or ...

Raman Spectroscopic Identification of Oxide Phases in a Corroded MgO–Steel Composite Anode Used in Aluminum Molten Salt Electrolysis

open access: yesAdvanced Engineering Materials, EarlyView.
Micro‐Raman spectroscopy is applied to characterize corrosion products in a recycled‐based MgO–316L steel composite anode after molten salt electrolysis. A depth‐dependent Fe–O/Fe–Al–O layer sequence of magnetite, hercynite, and an Al‐doped magnetite transition zone is identified.

A Norwegian ZEB-definition embodied emission

open access: yes, 2014
This report deals with how to define what a Zero Emission Building (ZEB) is with explanation and analysis of different parameters related to embodied emissions of CO2 equivalents. The report can be used as a guidance tool on how to assess embodied emissions, and also on what parameters should be evaluated in such an assessment.

Process map of carbon emission sources for stainless steel construction products [PDF]

open access: yes, 2017
The building sector plays an indispensable role in the mitigation of greenhouse gas (GHG) emissions as buildings are emission-intensive to construct and operate.

Interaction of MgO Recyclate‐Based Cermet Anode With KF‐AlF3‐Al2O3 at 800°C During Laboratory Scale Aluminum Molten Salt Electrolysis

open access: yesAdvanced Engineering Materials, EarlyView.
A carbon‐free, as‐sintered MgO–steel cermet anode, fabricated via cold isostatic pressing using MgO–C refractory recyclate, was evaluated under laboratory‐scale K‐cryolite electrolysis at 800°C. Operation at this reduced temperature, combined with the electrolyte's limited electrical conductivity, led to an increase in cell voltage.

Linking NAMEA and Input output for 'consumption vs. production perspective' analyses. [PDF]

open access: yes
We integrate input output and NAMEA tables for Spain and Italy in 1995, 2000 and 2005, in order to address the hot policy issue of sustainable consumption and production.

The environmental "trade balance" between Scotland and the rest of the UK : an inter-regional input-output and SAM analysis [PDF]

open access: yes, 2004
We use an inter-regional input-output (IO) and social accounting matrix (SAM) pollution attribution framework to serve as a platform for sub-national environmental attribution and trade balance analysis.
