1. In Japan there are 1800 treatment centres
to which human waste is delivered by vacuum
powered trucks from households in much the same
way that septic tanks are emptied. Research will produce a family sized
Vacuum toilet uses suction to reduce water use by 90%, and to gather
solid and liquid waste separately. The liquid waste is used for fertilizers,
while the solid is sent to a bioreactor and converted to electricity.
All in a flush.
Using sludge from a wastewater treatment plant, the
researchers are extracting lipids using heat, which can be converted to
biodiesel. Since sewage sludge is plentiful, the process is much cheaper
than converting vegetable oils to biofuels.
power from sewage sludge
A town has
transformed their sewage treatment plant into a renewable biofuel
mega system called
All-gas. The sewage flushed by citizens will combine with sunlight
and algae, to make biofuel that will run
a fleet of 200 cars owned by the town.
Since breaking down corn stalks and grasses for biofuel
requires removing lignin and breaking down cellulose, the process can be
expensive and complicated to perform. Scientists have discovered that these
processes happen naturally in horse manure,
thanks to an enzyme living in fungi that thrives within it. That said, using
horse poop for biofuel production is exponentially easier, and cheaper than
Engineers say it's possible to purify sewage water until it's
cleaner than much of what residents drink today.
