LEDs have always been environmentally friendly during the LED product life cycle, but if they can be recycled and reused, they will be more environmentally friendly. More than 95% of the LEDs are recyclable, and waste recycling companies will buy old LED lighting products at low prices.
When the LED does not contain any harmful substances, it is classified as RoHS. RoHS was passed in the UK in January 2006 to limit the use of hazardous substances in electrical and electronic equipment. This restriction prevents the sale of products containing mercury, lead, cadmium, polybrominated biphenyls, polybrominated diphenyl ethers and hexavalent chromium. Due to this standard, LEDs can be handled and recycled in the same way as regular light bulbs.
The general process of recycling is to crush and separate the LED bulbs, using a single screen to form the assembly. In this step, the glass passes through a magnetic field that can move any non-ferrous metal species. To remove the aluminum and lead of the LED, a non-ferrous metal separator blasts in the shattered glass, directing the metal to a separate metal trough. The rest of the glass can be made into other products just like aluminum. Glass is not degraded by recycling, so it can be recycled and reused.
In the UK, LED lighting is managed by the WEEE standard to determine when LED products should be eliminated. WEEE is the abbreviation for waste electrical and electronic equipment, and the standard for recycling electrical and electronic equipment developed to encourage mass recycling. Recently, the EPA has changed the WEEE regulations, and all LED companies must comply with them, such as Recolight. Under the new regulations, people must check whether the lighting producers have the cost of recycling according to WEEE 9.2.
Recycling LEDs for environmental benefits
Although the LED itself is environmentally friendly, if the LED is properly recycled, the impact on the environment will be smaller. According to a recent study by the University of California, most LED lamps contain a high proportion of nickel, and color LED lamps contain a large amount of lead. In addition, the arsenic content is also exceeded. These substances are not only harmful to the environment, but also endanger human health. Although LEDs are more environmentally friendly than traditional lamps, they cannot be used as if they were used up. The effects of LEDs may be long-term. LEDs also contain a large amount of aluminum, which may be due to the energy and resources used in manufacturing. In view of the increasing demand for LED lamps in recent years, recycling LEDs is more important than extending the life of LEDs, making it possible to continue to use LEDs in the future. Therefore, the recycling of LEDs is particularly important and necessary!
