CEA Pollution Prevention & Waste Minimization 2

Question 1

Which of the following best describes 'closed-loop recycling' in an industrial setting?

Accepted Answer

Reintegrating a process by-product back into the same process as a raw material

Answer

Closed-loop recycling means a by-product or waste stream is fed back into the same production process as a raw material substitute, keeping the material within the facility's operations.

Question 2

An environmental auditor reviewing a facility's Tier II chemical inventory notices a sharp increase in reported acetone quantities. In a P2 context, what is the most likely root cause to investigate?

Accepted Answer

Increased production volume without corresponding process efficiency improvements

Answer

A sharp increase in reported chemical quantities typically suggests production growth without efficiency gains, making process optimization a key P2 opportunity to investigate.

Question 3

The EPA's 33/50 Program was a voluntary initiative that asked companies to reduce releases of 17 priority chemicals. The primary mechanism for achieving these reductions was:

Accepted Answer

Voluntary commitments to source reduction and recycling

Answer

The 33/50 Program was entirely voluntary, relying on facility commitments to reduce TRI-reported releases through source reduction, recycling, and process improvements.

Question 4

Which document typically serves as the baseline for a facility-level pollution prevention planning effort?

Accepted Answer

A material balance or process flow analysis

Answer

A material balance or process flow analysis quantifies all inputs, outputs, and losses in a process, identifying where waste is generated and providing the baseline for P2 planning.

Question 5

A facility reduces its hazardous waste generation by implementing better housekeeping practices such as promptly closing solvent containers and fixing dripping valves. This strategy is classified as:

Accepted Answer

Good operating practices — source reduction

Answer

Good operating practices such as proper container management and leak prevention are recognized source reduction techniques under the Pollution Prevention Act.
