Special Issue Information

Dear Colleagues,

The mining and metal industry is facing several issues related to high energy consumption. Low-carbon technologies are needed to optimise the use of energy, an ever-increasing need. Low-carbon technologies demand higher percentage of the world's mineral production. Sustainable and eco-efficient processing of these minerals and materials is the focus of this Special Issue. The developing countries and emerging economies need to practice innovative mining and materials processing to keep the carbon and material footprint low. The economies associated with crucial metals production include India (iron, steel, and titanium); The Democratic Republic of Congo (copper, cobalt); Mozambique and Madagascar (graphite); China (rare earths); China, Brazil, Indonesia, Guinea (bauxite); Mongolia, Peru, Columbia, Indonesia Chile (copper); Indonesia (nickel); etc. There will be growing demand for the following minerals as we transition towards low-carbon technologies: lithium, cobalt, graphite, indium, vanadium, nickel, silver, neodymium, molybdenum, aluminium, copper, manganese, etc.

This Special Issue will focus on current and future development in decarbonizing high materials and carbon footprint processes. This includes innovation in energy and emission reduction, design manufacturing for recycling, and reuse. The keywords for the recommended topics are given below. However, the submissions for this Special Issue should not be limited to these. This Special Issue will build on the existing knowledge in the literature and report on advances in the area.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sustainability is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Greenhouse gas (GHG) emissions from human activities have climbed significantly above pre-pandemic levels and have reached record highs that unequivocally accelerate global warming. Industry has a significant impact on climate change, emitting at least 21% of global GHGs and making little overall progress toward its reduction until now. Reducing industry’s emissions requires coordinated action along the value chains in order to promote mitigation options, such as energy and material efficiency, circular material flows, and transformative changes within production processes. This article is the first evaluation of GHG emissions generated during the manufacturing of vehicle components by Austrian companies. For this, the authors analyzed three different products of automotive suppliers according to the methodology of ISO 14067. Despite previous efforts toward an environmentally compatible fabrication, additional and significant reduction potentials were identified. These measures for product carbon footprint (PCF) reduction included the sourcing of low-carbon materials (which are already available on the market), more extensive use of renewable energy, and changes towards more resource efficient manufacturing processes and machinery. Depending on the materials used, the PCF can be reduced by up to 80%. The findings serve to prepare for future PCF reporting regulations and illustrate reduction potentials to achieve future market advantages, especially when PCFs become an awarding criterion.
