fertiliser as manure.
If we got rid of the livestock these would have to be replaced with industrial equiva-
lents.
A 2015 study warns
lab-grown meat could just create a whole bunch of new prob- lems: “From this per- spective, large-scale cultivation of in-vitro meat and other bio- engineered products could represent a new phase of industrialisa- tion with inherently complex and challeng- ing trade-offs.”
On its website, Just argues: “We think it’s unlikely that families in Alabama (or anywhere in the world) will con- sistently choose plant- based alternatives over chicken, beef, pork and seafood.”
“And when you’re talking animal protein, higher unit volume and accordingly lower prices will necessar- ily mean industrialised animal production.
“There’s no conven- tional way around this math.”
Can it be sold in Aus- tralia?
The short answer is yes, but each different lab-grown meat prod-
uct will need to be test- ed by Australian health and safety authorities first.
The real question is what it would be called. In Australia, meat is defined as “the whole or part of the carcass if slaughtered” of “any
animal”.
As QUT law lecturer
Hope Johnson notes in a Conversation arti- cle, a key selling point of lab-grown meat is that nothing has been slaughtered, so lab- grown meat companies would not want to sat- isfy that legal defini- tion of ‘meat’.
The alternative is vague product names without the word meat – something like ‘Quorn’, the meat sub- stitute product made from soil mould.
Either way, farmers might push back.
Earlier this year, Deputy Prime Minister Michael McCormack called out the linguistic trickery of ‘plant-based mince’.
“Mince is mince, mince is meat,” he said.
“That’s my interpre- tation of what mince is.”

EDUR DAF pump saves capital cost, energy and maintenance costs
A SINGLE dissolved air flotation pump is able to replace the entire air bubble system on DA F plants according to pump supplier Hydro In- novations.
EDUR multiphase pumps draw water in from the ‘clean’ end of the DAF tank as well as bring air in through a snorkel in the suction line.
The pump shears the air and then feeds it at pres- sure through an enlarged solution line, then back into the DAF plant, pro- ducing a discharge stream into the tank that is satu- rated with 30 to 50-mi- cron air bubbles.
Conventional DAF sys- tems consist of a waste- water tank, compressor, air saturation vessel and effluent pump.
The effluent pump draws effluent from the tank and pumps it into the air saturation vessel.
A compressor pumps air into this same vessel.
The air/water mixture is ‘saturated’ under pressure, then released back into the wastewater tank at atmos- pheric pressure where tiny bubbles form and adhere to the suspended matter (fats, oils and other small waste- water particles).
The bubbles (with their attached suspended mat- ter) float to the surface of the tank, where floatables can be skimmed off the surface.
By using EDUR mul- tiphase pumps, which can produce the same micro- bubbles, asset owners can do away with the com- pressor, the air saturation vessel and any control or ancillary components for these items.
The reduction of these system components and the simplification of the design results in lower in- vestment costs and higher operational reliability.
The EDUR multiphase pump is an efficient al- ternative.
Now, one pump can re- place the conventional pump, air saturation tank and compressor.
Energy and mainte- nance costs of running the compressor are elim- inated.
EDUR multiphase pumps can deliver flows from 1l/s (for smaller DAF plants) to 15l/s (for larger DAF plants) and produce pressures to 12 bar (174psi).
A variety of materials and seal arrangements en- able EDUR pumps to op- erate in a very wide range of applications.
Available materials in- clude ductile iron, ‘gun- metal’ bronze, stainless steel and super duplex.
Mechanical seals are available as balanced, double and tandem.
