The most ecological way of getting rid of spent malt is
to compost together with leaves, clippings and organic
waste from the kitchen. (I keep a separate compost box
for the spent hops as they have a high acidic level and
makes a great compost for specific flowering plants in
the front garden.)
deliveries in Emilia Romagna we use our methane powered Opel Combo
which pollutes very little when compared to deisel,
petrol and LPG powered vehichles.
Any remianing water after a brew is reused in the
cleaning of the brewery and used to water the veggie
patch - which, along with bio veggies and herbs,
contains samples of the English hops East Kent Goldings e Fuggles.
