Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Anaerobic Digestion involves the use of microorganisms to break down organic waste in the absence of oxygen, producing biogas (a mixture of methane and carbon dioxide) and a nutrient-rich digestate.

Multiple choice

Which of the following is NOT a common method used to remediate soil contaminated by mining?

  1. Phytoremediation

  2. Bioremediation

  3. Chemical remediation

  4. Landfilling
