Biotechnologies for Critical Raw Material Recovery from Primary and Secondary Sources: R&D Priorities and Future Perspectives
Europe is confronted with an increasing supply risk of critical raw materials. These can be defined as materials of which the risks of supply shortage and their impacts on the economy are higher compared to most of other ...
Outdoor fate and environmental impact of polymer solar cells through leaching and emission to rainwater and soil
The emission of silver and zinc to the aq. environment (rain, fog, dew) from polymer solar cells installed outdoors is presented. Studies included pristine solar cells and solar cells subjected to mech. damage under natural ...
Incineration of organic solar cells: Efficient end of life management by quantitative silver recovery
Recovery of silver from the electrodes of roll-to-roll processed org. solar cells after incineration has been performed quant. by extn. with nitric acid. This procedure is more than 10 times faster than previous reports ...
Antimony retention and release from drained and waterlogged shooting range soil under field conditions
Many soils polluted by antimony (Sb) are subject to fluctuating waterlogging conditions; yet, little is known about how these affect the mobility of this toxic element under field conditions. Here, we compared Sb leaching ...
Methodological approaches for fractionation and speciation to estimate trace element bioavailability in engineered anaerobic digestion ecosystems: an overview
Optimal supply of trace elements (TE) is a prerequisite for microbial growth and activity in anaerobic digestion (AD) bioprocesses. However, the required concentrations and ratios of essential TE for AD biotechnologies ...
