Abstract
The light-emitting diodes (LED) in recent times, have become the most energy-efficient and rapidly develo** lighting technology. However, it has been found that LED contains various perilous valuable materials that make their recycling essential. It also helps to recover rare earth elements and maintains the eco-balance of the planet. The environmental and economic assessments are being carried out in this study. The CO2 emissions for recycling one tonne of LED bulbs were estimated to be in the range of 6.21 × 10–3–5.52 × 10–2 tCO2. The cost of LED bulbs recycling is estimated as Rs 20,221–20715 per tonne. The LED recycling should be promoted to reduce the cost of material processing (such as Ag, Au, As, Ga, Cu, Fe, Zn and other rare earth metals etc.), However, recycling comes at a cost of energy, process operations and manpower resources. LED bulb recycling is cost effective, eco-friendly and also helps to achieve the United Nations Sustainable Developmental Goals.
