In this study, we investigate the potential for reuse and recycling – the two key pathways promoted by CE – for waste electrical and electronic equipment (WEEE) management.
This study aims to develop a highly selective optical mesoporous conjugate adsorbent for efficient optical detection, sorption and extraction of cerium (Ce(III)) from waste effluents.
The Nd and Ce co-doped zirconia waste form exhibit excellent aqueous durability (∼10−5 g m−2 d−1).
The principal theme of this contribution is the maximization of resource efficiency as well as enabling a circular economy (CE) through the recycling of waste electric and electronic equipment, with a focus on precious metals (PMs) (incorporating gold, silver, and the platinum group metals [PGMs]) and the base-metal industry that enables their recycling.
The CE scenario also has as little waste as the limited growth scenario, and far less than the other scenarios or the 2012 baseline.
Therefore, the design of optical conjugate adsorbent has a great potential to be used in efficient, selective and simultaneous Ce(III) detection, sorption and extraction from waste and can be used of nuclear power plants wastewaters treatment effectively.
CE is associated with a variety of concepts, and waste management emerges as the most relevant sub-sector.
MFC-U and MFC-C exhibited during days 35 and 42, a calculated CE of 15.6 and 19.6%, respectively), both of which were in the typical range observed for MFCs fed with waste or wastewater [ 19, 38] while CE, in MFC fed with acetate-based synthetic media, may rise up to 98% [ 13].
The activated carbon (AC) was obtained from waste scrap tires and modified by bimetallic Fe and Ce nanoparticles in order to combine both the high surface area and the active sites for enhanced adsorption of the dye.
The circular economy (CE) aims to radically improve resource efficiency by eliminating the concept of waste and leading to a shift away from the linear take-make-waste model.
