Biogas is a mixture of gases, primarily consisting of
methane (biomethane), carbon dioxide and hydrogen sulphide, produced from
organic materials such as agricultural waste, manure, municipal
waste, plant material, sewage, green waste and food waste.
We sell and/or install biogas anaerobic digesters. You can throw in any
organic material and it will provide you with biogas and liquid
fertilizer. Biogas is renewable energy and can be
used as a Renewable Natural Gas (RNG)
alternative. Ideal for cooking gas and hot water
systems. You can even power a generator for
electricity or motor vehicles.
A home biogas solution is an outstanding option for
off-grid living, but we'd recommand them for every a
family house, farm and/or business. It's basically FREE
energy, while helping the planet.
We'd recommand the system is used outdoors for warm/hot
climate locations (e.g. Queensland and Darwin). For colder
climates (e.g. Tasmania) we recommand the system is used
indoors with the heater accessory we offer (installed within
the digester). For areas like NSW - either option will likely
Unlike similar systems known as soft biogas digesters. This
solution is enclosured in a greenhouse to maximise efficiency
and reduce process (aka retention) time. This design uses a
stainless steel frame, sink and outlet - instead of
plastic - this ensures a long-lasting design, protected from
the elements such as weather and animals if used outdoors.
It is possible you have seen some biogas digester systems
connected to a human toliet. Humans do not produce much
methane - it takes a tribe of people to produce the methane
of a single cow. So these human toliet focused systems require
continuously introducing fermentation
powders. Furthermore, any animal/human that eats meat will
have pathogens, which will increase digester process
(aka retention) time to kill the pathogens. It is for these
reasons - we suggest avoiding using humanure. In short -
a good biogas digester mimics a cows gut, so food waste, green
waste and manuare from herbivore animals are likely the best
sources of feed for a biogas digester. All that said, meat
products can be fed into the system with low retention time,
when used in warm/hot climates or in cold climates with
internal digester heater.

I have a compost - is the liquid fertilizer better?
Yes - it's concentrated and proven to provide better yield for
crops. You can also throw meat and fish into the digester unlike a
Can I use an existing LPG stove with biogas?
We'd recommand a biogas stove, however in theory you can mix
biogas with LPG, to use with a traditional LPG stove.
Can I use an existing petrol generator?
We'd recommand a biogas generator, however in theory you can
start the generator with petrol, then switch to biogas.
Can I use an existing LPG hot water system with biogas?
We'd recommand a biogas hot water system, however in theory you can mix
biogas with LPG, to use with an traditional LPG hot water system.
Does the biogas hot water system water pressure match a
typical home LPG hot water system?
The above 3.4m³ provides about half the flow rate and half
the water pressure of a typical LPG hot water system. But if you
join two of these systems together it should achieve the flow rate
and water pressure of typical home. However this means more organic
material to feed the digester.
Can I grow plants to feed the system?
Yes - and plants are a renewable source. We'd recommand they are
shredded before putting into the digestor for optimal performance
Can I compress biogas?
Yes - but something we don't offer at this stage.
