Catalytic converters, having expensive metals namely platinum-palladium and rhodium as the catalysts, are fitted into automobiles for reducing emission of poisonous gases. As the exhaust passes through the catalytic converter, unburnt hydrocarbons are converted into carbon dioxide and water, and carbon monoxide and nitric oxide are changed to carbon dioxide and nitrogen gas, respectively. Motor vehicles equipped with catalytic converter should use unleaded petrol because lead in the petrol inactivates the catalyst.

Electrostatic precipitator ,which can remove over 99 per cent particulate matter present in the exhaust from a thermal power plant. It has electrode wires that are maintained at several thousand volts, which produce a corona that releases electrons. These electrons attach to dust particles giving them a net negative charge. The collecting plates are grounded and attract the charged dust particles.
The velocity of air between the plates must be low enough to allow the dust to fall.

Earmuffs for Noise Reduction: Earmuffs are personal protective equipment (PPE) used to reduce exposure to high noise levels. They do not eliminate the source of noise but provide hearing protection to individuals working in noisy environments.

Landfills for Solid Waste: Landfills are designated areas for the disposal of solid waste. Solid waste is deposited in these sites and is managed in an environmentally responsible manner to minimize its impact on the environment.
