RECYCLING OF ORGANIC SLUDGES
With
the introduction of tighter EU
Legislation and Regulation, it is
more difficult and essential for
waste producers to dispose of their
waste in a compliant and
environmentally sound manner. We
have
worked for several years on the
bio-filtration of sludge (sewage
sludge or industrial sludges) by
willow plantations.
The process that Rural Generation
has pioneered works as follows:
 Bespoke
trailers are filled, covered
with tarpaulin and taken to
willow establishments.
The
trailer tips the sludge into an
auger. Deodoriser is applied as
it transfers from the trailer to
the auger.
The
sludge is augered into a bespoke
injector trailer.
The
injection trailer is towed
behind a tractor through the
field.
The
trailer cuts a track in the
ground, between newly harvested
willows, a screw augers the
sludge into the trench and discs
on the trailer fold the soil
over the sludge.
Finally
the trailer wheels role over the
covered injection trough,
completely covering and sealing
the sludge under the soil
surface.
The willow subsequently produced is
a low-carbon, renewable energy
source. The process has taken
nutrients out of waste streams and
reduced the levels of pollutants in
the environment.
