Which disposal method uses injected water and air to accelerate decomposition and reduce the volume of waste?

• A. Remediation
• B. Bioreactor Landfill
• C. Mass Burn
• D. Design For Recovery

Answer: (B)

Moisture and air management to speed biodegradation is the idea here. By injecting water and supplying air, a bioreactor landfill creates conditions that boost microbial activity, so waste breaks down faster and stabilizes sooner, which also helps reduce the remaining waste volume. This approach is specifically about accelerating biological decomposition through controlled moisture and aeration, distinguishing it from other disposal methods that don’t use injected water and air to drive rapid biodegradation. Remediation is cleanup of contamination, mass burn is incineration with energy recovery, and design for recovery focuses on planning for material recycling and resource recovery rather than speeding up biological decay.
