Hey Theresa, the correct answers turn green when you select them (if you choose an incorrect answer, you'll see an "X" and the answer will turn gray. I'll add a "correct" msg to the right answers too, to make it clearer when you choose the right one. Thanks for the question / feedback!

This was a really great story on what happens to our poop! However, there are several other ways that we use biosolids to close the loop. Some wastewater treatment plants have gasifiers that dry the biosolids and turn them into a syngas which they burn for fuel. Other plants use anaerobic digestion from which they can extract methane and use as fuel. But if the biosolids make their way to the landfill, they will produce methane as they decompose, which the landfill is required to collect. Some landfills burn the methane for energy or send it to powerplants to use as fuel.

Plus, the use of biosolids as fertilizer isn't as limited as the podcast made it sound. Lots of wastewater treatment plants treat their sludge to either class A or class B standards which can then be used as fertilizer!
