Cost-benefit analysis

Definition

Cost-benefit analysis is a systematic approach to evaluating the strengths and weaknesses of alternatives in order to determine the best option for decision-making. It involves comparing the total expected costs of a project or decision against the total expected benefits, allowing for an informed choice that maximizes positive outcomes. This tool is essential when considering advanced treatment options for contaminants, evaluating energy recovery initiatives, and exploring ways to recover resources from wastewater.

5 Must Know Facts For Your Next Test

1. Cost-benefit analysis is often used to justify investments in new technologies or processes by demonstrating their economic viability compared to existing methods.
2. In the context of pharmaceutical removal, this analysis helps identify the most effective treatment options while considering financial implications and potential health benefits.
3. Energy recovery opportunities can be assessed through cost-benefit analysis by weighing the costs of implementing recovery systems against potential savings and energy outputs.
4. Resource recovery from wastewater can be analyzed through this method to ensure that the benefits derived from recovered materials outweigh the costs of extraction and processing.
