• An electrostatic precipitator($ESP _s$) is a device that removes suspended dust particles from a gas or exhaust by applying a high-voltage electrostatic charge and collecting the particles on charged plates. It can remove 99% of particulate matter from thermal power plant exhaust.
• e-waste is discarded electronic appliances such as mobile phones, computers, and televisions. Over half of the e-waste generated in developed countries are exported to developing countries, mainly to China, India, and Pakistan, where metals like Cu, Fe, Si, Ni, etc., are recovered during the recycling process.
• Nuclear waste is the radioactive waste material, for example from the use or reprocessing of nuclear fuel. Hence Use of nuclear energy has two very serious inherent problems first is accidental leakage and the second is the safe disposal of radioactive wastes. Hence It has been recommended that storage of nuclear waste after sufficient pretreatment should be done in suitably shielded containers buried within rocks about 500m deep to prevent its harmful effects.
• So, the correct answer is 'All the above',
