CEA Pollution Prevention & Waste Minimization

Question 1

According to the U.S. Pollution Prevention Act of 1990, what is the preferred approach in the pollution management hierarchy?

Accepted Answer

Source reduction at the point of generation

Answer

The Pollution Prevention Act establishes source reduction as the most preferred approach, meaning preventing pollution before it is created rather than managing it after the fact.

Question 2

A facility wants to reduce solvent waste from its degreasing operations. Which pollution prevention technique represents source reduction?

Accepted Answer

Switching to aqueous cleaning systems

Answer

Switching to aqueous (water-based) cleaning eliminates the use of hazardous solvents entirely, which is source reduction — preventing waste generation at the source.

Question 3

Which metric is most useful for tracking a facility's waste minimization progress over time?

Accepted Answer

Waste generation rate normalized to production output

Answer

Normalizing waste generation to production output accounts for changes in production volume, making it the most meaningful indicator of true waste minimization progress.

Question 4

Under EPA's waste management hierarchy, which option ranks highest after source reduction?

Accepted Answer

Environmentally sound recycling

Answer

EPA's waste management hierarchy places source reduction first, followed by environmentally sound recycling (including reuse), then treatment, and finally disposal.

Question 5

A paint manufacturer implements a raw material substitution to replace a volatile organic compound (VOC)-based solvent with a water-based alternative. This change primarily reduces:

Accepted Answer

Air emissions from the painting process

Answer

Replacing VOC-based solvents with water-based alternatives directly reduces air emissions since VOCs evaporate into the atmosphere during application and drying.
