At the moment, there are many electrical appliances operating on LEDs. These light emitting mechanisms provide a good alternative to standard electric lamps. However, their use causes a negative impact on the environment, since the LEDs contain toxic materials.
To correct this side effect, specialists from the University of Utah have developed a methodology for the production of diodes from waste in which there are no toxic elements. If these products are of interest to modern manufacturers, then toxic LEDs can be abandoned. This will reduce the amount of waste that needs to be recycled.
The working element of light-emitting parts is quantum dots (QDs), such crystals with luminescent properties. They are mainly produced using nanofibers, which are based on carbon. The advantage of these nanodots is that they have a low amount of toxic substances.
Modern research shows that LEDs can be obtained from food waste. The ideal raw material for this is bread leftovers and soft drinks. However, production requires special equipment and sophisticated technologies that already exist.
