Environmental and economic perspective of waste-derived activators on alkali-activated mortars
(Elsevier, 2020-10-14)
Alkali-activated binders have been considered a low carbon alternative to cement and are produced by reacting aluminosilicate precursor with an alkali-activator. However, alkali-activators have been observed to be a major ...
A life cycle environmental sustainability analysis of microbial protein production via power-to-food approaches
(Springer, 2020-09-21)
Purpose
Renewable energy produced from wind turbines and solar photovoltaics (PV) has rapidly increased its share in global energy markets. At the same time, interest in producing hydrocarbons via power-to-X (PtX) ...
Environmental impacts of manure management based on life cycle assessment approach
(Elsevier, 2020-04-20)
Horse manure is often a cost for horse owners, and in most cases, it is underutilized when its status as biodegradable waste means that it could potentially be used in renewable energy production and serve as a source of ...
Water-energy nexus and greenhouse gas–sulfur oxides embodied emissions of biomass supply and production system: A large scale analysis using combined life cycle and dynamic simulation approach
(Elsevier, 2020-06-23)
The achievement of low or zero greenhouse gas and particulate matter emissions such as sulfur oxides, optimized water-energy nexus, and a well-protected environment are challenges that have become increasingly significant ...
Recycling mica and carbonate-rich mine tailings in alkali-activated composites: A synergy with metakaolin
(Elsevier, 2020-08-12)
The main objective of this paper was to investigate the alkali activation of mine tailings (MT) after mechanochemical activation and the effect of metakaolin (MK) addition. Finnish mica-rich tailings from a phosphate mine ...
