Question 27

Vented pipes are installed

To manage the release of gases produced by decomposing trash in a decommissioned landfill, vented pipes are installed. This method allows the gases to be safely released or collected, preventing harmful emissions into the atmosphere.

A) Compost material is added

Adding compost material is not a relevant action for accounting for the release of gases in a decommissioned landfill. While composting can aid in waste management and reduce overall landfill volume, it does not address the specific issue of gas release from decomposing trash.

B) Fans are installed

Installing fans is not a standard practice for managing landfill gases. While fans may help in ventilation in certain contexts, they do not provide a controlled method for gas release or collection in a landfill setting, making this option ineffective for the issue at hand.

C) The trash is transferred to a new location.

Transferring trash to a new location does not resolve the gas release problem in a decommissioned landfill. This option merely relocates waste without addressing the underlying issue of gas production from decomposition, thus failing to mitigate the environmental impact.

D) Vented pipes are installed

Vented pipes are specifically designed to manage the gases produced by decomposing waste. By allowing these gases to escape or be collected, this method effectively mitigates the risks associated with gas accumulation, making it the most appropriate action for this scenario.

Conclusion

The installation of vented pipes is the most effective solution for addressing the release of gases from decomposing trash in a decommissioned landfill. Other options, such as adding compost, installing fans, or relocating trash, do not directly manage gas emissions and fail to provide a viable resolution to the environmental concerns posed by landfill gas.
