--and disgusting--proposition, but some researchers think that a
mix of cheese whey (a cheese-making byproduct) and liquid cow
manure may come together to make a high-quality biogas. Cheese
whey isn’t a problem for most dairy farms, but for the 100 or so
in the U.S. that produce massive amounts of cheese and millions
of pounds of whey each year, it starts to add up. The stuff
isn’t usable in anaerobic digesters (which are commonly used to
turn farm waste into biogas) because it acidifies quickly, and
while many farmers put it on their fields for fertilizer, there
is still often leftover whey. Use it while you have it: Water
