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 ...
Environmental Assessment of Alkali-Activated Mortars Using Different Activators
(CISA Publisher, 2019-10)
This study sheds light on the environmental performance of three alkali-activated mortars (AAMs) using sodium hydroxide, sodium silicate powder and 2-part aqueous alkali solutions respectively, as activators. A comparative ...
Life cycle assessment of a low-height noise barrier for railway traffic noise
(Elsevier Ltd., 2021-09-25)
Life cycle assessment (LCA) methodology was applied to assess five locally developed mix designs for a 20 m low-height noise barrier (LHNB) categorized as: precast Portland cement concrete (S0-baseline scenario), two precast ...
Influence of different factors in the life cycle assessment of mixed municipal solid waste management systems – A comparison of case studies in Finland and China
(Elsevier, 2017)
The life cycle assessment (LCA) of municipal solid waste (MSW) management systems is typically rather arduous due to extensive data acquisition needed to calculate the direct and avoided emissions of the systems. A possibility ...
Environmental impacts of wooden, plastic, and wood-polymer composite pallet: a life cycle assessment approach
(Springer Nature, 2021-07-13)
Purpose
Waste recycling is one of the essential tools for the European Union’s transition towards a circular economy. One of the possibilities for recycling wood and plastic waste is to utilise it to produce composite ...
Integrating Pyrolysis or Combustion with Scrubbing to Maximize the Nutrient and Energy Recovery from Municipal Sewage Sludge
(MDPI, 2021-08-04)
Based on mass and energy balance calculations, this work investigates the possibility of recovering heat and nutrients (nitrogen and phosphorus) from municipal sewage sludge using pyrolysis or combustion in combination ...
Consequential life-cycle assessment of treatment options for repulping reject from liquid packaging board waste treatment
(Elsevier, 2022-11-21)
Liquid packaging board is one of the highly demanded packaging mediums for liquid food and beverages, generating substantial waste each year. Even though the fibre part of the liquid packaging board is recycled through a ...
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 ...
The effect of conductive ink alternation on the sustainability and functioning of printed electronics
(IOP Publishing, 2023-05-30)
The demand for printed electronics (PE) is expected to increase for improved functionality and autonomy of products in the context of the Internet of Things, especially for sensing and communication. With this trend, the ...
Cu-BTC-based composite adsorbents for selective adsorption of CO2 from syngas
(Elsevier, 2021-09-03)
High CO2 content exists in the raw syngas produced from supercritical water gasification of food waste, CO2 removal to improve quality of the syngas is necessary before further utilization. In this study, Cu-BTC, Mg/Cu-BTC, ...
