Which is another example of reducing pollution at the source in industry?

• A. Improving process efficiency to minimize waste
• B. Dumping waste into waterways
• C. Increasing production pace without changes
• D. Relying only on end-of-pipe controls

Answer: (A)

Reducing pollution at the source means preventing pollutants from being created in the first place by changing how production is done. Improving process efficiency to minimize waste fits this approach because it streamlines operations, uses fewer raw materials, reduces scrap, and cuts the amount of waste and emissions generated during production. This not only lowers pollution but often saves costs as well, since less waste needs disposal or treatment.

Dumping waste into waterways releases pollutants after they’re formed, so it doesn’t prevent pollution at the source. Increasing production pace without changes tends to increase waste and emissions rather than reduce them. Relying only on end-of-pipe controls means addressing pollution after it’s already been produced, rather than preventing its creation in the first place.
