What is pollution prevention, and provide an industrial example?

• A. Strategies to hide pollution from regulators
• B. Increasing production length without waste changes
• C. Relying solely on end-of-pipe treatment after generation
• D. Practices to reduce waste at the source; example: switching to less hazardous solvents or improving vessel efficiency to reduce solvent losses

Answer: (D)

Pollution prevention means keeping pollutants from being created in the first place by designing processes and choosing materials that generate less waste and emissions. In practice, this involves things like substituting hazardous solvents with less harmful ones, optimizing equipment and process controls to cut losses, and recovering or reusing materials so less waste is produced overall. These are proactive steps that stop waste at the source rather than dealing with it after it’s already formed.

An industrial example is switching to less hazardous solvents or improving vessel efficiency to reduce solvent losses. By choosing safer solvents or tightening equipment performance, a plant can significantly cut solvent waste, lower environmental and safety risks, and often save costs.

Other ideas described in the choices don’t fit the concept because they focus on hiding pollution, extending production without reducing waste, or treating pollutants after they’re generated instead of preventing their creation in the first place.
