When preparing a new procedure or designing a new experiment …
• Ben evaluates the types and
quantities of waste products
• uses the smallest possible
amount of water required
• and considers possible
methods to reduce or
eliminate liquid waste.
To maintain its quality for a
longer period of time,
• they do not share it with
other laboratories /
schools
• they also avoid filling it
to it’s recommended
capacity before using it.
This is the lab’s autoclave unit.
This is the lab’s water
aspirators.
It’s an old model which
consumes approximately 22
litres/minute, when in use.
It’s around 8 years old and they don’t like overloading it so
they run it when it’s half full.
This is their dishwasher.
This is their bench-top
return dish, where they
discharge chilled water.
Using this dedicated return point
ensures that chilled water goes
back into the system’s return line
for re-use.
They do not discharge cooling
water in the sink anymore.
This is their evaporative cooler
They pass by this site
every morning and the
wet patch next to it
seems to get bigger each
week.
They have ablution basins…
with special hands-free tap ware,
which operate at 4L/min.
Their old installations have also
been retrofitted with in-line
devices restricting flow to 4L/min
or restricting duration of flow
using timed flow taps.
The lab use the building’s
primary closed circuit chilled
water loop to provide this
service.
Sometimes, to provide apparatus cooling…
