Global - Charles IFE
Global Environment Corporation Pty Ltd. has joined
with Charles IFE Pty Ltd. to promote a new technology
for total waste mangement in the Pig Industry. The fully
intergrated waste treatment and recycling system converts
all the waste from a piggery into electricity, organic
fertiliser and recycled water. The Global/Charles IFE
Total Waste Management System is an integrated management
strategy to address pollution by using the untapped
resources in manure. This generates viable and sustainable
financial return as well as other benefits.
|
The Technology
|
|
|
The system comprises 8 main processes
that, together, convert organic waste from the piggery
into:
a) clean mineralised
waters,
b) solid humic bio-fertilisers
and
c) power, heat and carbon
dioxide.
|
In conventional intensive pig
production systems, only a fraction of the potential
energy value of the feed is utilised. Unmetabolised
nutrients are passed in the manure and if not properly
treated, become pollutants as well as a wasted resource.
The consequences of poor waste management in this industry
are:
a) the degradation of
water resources and
b) methane (green house
gas) release to atmosphere.

Figure 1: Total Piggery Waste
Management
These processes are depicted in Figure 1
Organic waste is collected, homogenised
then thickened
(processes 1, 2
& 3) and separated waters from
these processes are recirculated into the farming system.
The sludge from (3) is passed on through two
anaerobic digesters (4 & 5) and a
sludge dehydrator (8) to produce bio-gas and
organic humic fertilisers and mineralised waters. Options
then exist for utilising or marketing the fertilizer
and the bio-gas can be further purified (6) and
utilised for thermal and electrical power generation
(7).

|
The benefits of this waste mangement system include:
|
|
a) Reduction of BOD and
the polluting power of the organic waste when converted
to thickened sludge.
b) Elimination of odour,
pathogens and seed from waste.
c) Improvement of the
manurial value of the waste.
d) Improved storage,
handling and utilisation of the wastes.
|
e) On-farm production of
energy.
f) Improvements in working
and living conditions, elimination of some pests and
reduction in flies and mosquito breeding areas.
g) Increased opportunities
for long term farm development options.
e) Re-cycling of all by
products and minimisation of waste.
