Recycling of Aluminosilicate-Based Solid Wastes through Alkali-Activation: Preparation, Characterization, and Challenges

Recycling aluminosilicate-based solid wastes is imperative to realize the sustainable development of constructions. By using alkali activation technology, aluminosilicate-based solid wastes, such as furnace slag, fly ash, red mud, and most of the bio-ashes, can be turned into alternative binder materials to Portland cement to reduce the carbon...

Life cycle assessment in wastewater treatment:: Influence of site-oriented normalization factors, life cycle impact assessment methods, and weighting methods

This present study aims to analyze the differences in results of different site-directional life cycle assessment<br/>(LCA) methods applied in the field of wastewater treatment. Site-generic methods were employed and<br/>compared with China-specific methods on a full-scale wastewater treatment case. A set of Chinese<br/>normalized factors were...
