E-waste includes discarded electronic devices like phones, computers, TVs and their components as well as batteries and appliances. Improper disposal of e-waste pollutes water sources and air with toxic chemicals, and wastes valuable resources. Proper e-waste management practices include reuse, recycling, donation, and responsible disposal to reduce pollution, conserve resources, and provide economic and social benefits. However, challenges include lack of infrastructure in developing countries, illegal dumping, and limited public awareness of e-waste issues.
