Novel Processing Methods of Low-Clinker Multi-Component Cementitious Materials—A Review
Applied SciencesThe wide use of multi-component cement of highly reduced Portland clinker factor is largely impeded by detrimental changes in the rheological properties of concrete mixes, a substantial reduction in the early rate of cement hardening, and sometimes the ...

Chemie Ingenieur Technik, EarlyView.The steel industry accounts for about 7%‐9% of global CO2 emissions. While H2‐based direct reduction is a long‐term route, near‐term solutions are needed for existing plants. Internal carbon cycles reuse steelworks off‐gases and by‐products, enabling circular carbon use and supporting CCU integration.

Prospective LCA of E‐Methanol Along the Transformation of Steel Industry
Chemie Ingenieur Technik, EarlyView.The environmental effects of change in steel production route on e‐methanol production are analyzed as they shift from blast furnace route to direct reduction route. Specific hydrogen demand reduces, as do the avoided CO2 emissions. E‐methanol's overall carbon footprint stays in a narrow range of −1 to −1.1 kg‐CO2‐eq./kg‐methanol.

Modelling Sustainability Performance in Manufacturing Companies
Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT Nowadays, organisations need to operate with economic, social and environmental goals in mind. Indices objectively quantify such goals; hence, an organisation can develop and compare policies based on future index values. We propose a system dynamics‐based model of a manufacturing company that frames its operations in terms of a set of easily ...

Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT Recent scholarship shows growing interest in the circular economy (CE) approach, which promotes resource‐efficient, community‐friendly activities. However, scientific evidence is still needed on the synergies and trade‐offs between CE and community development (CD).
