Green Camel using barramundi waste to grow organic plants

Green Camel disrupts conventional methods of production in horticulture and aquaculture. The company developed a technology and biological processes to grow vegetables and fish in a symbiotic and ground-breaking way.


  • Green Camel is striving to make organic and pesticide-free produce mainstream in Australia.
  • They deliver certified organic produce without the waste or environmental risk of conventional farming.
  • Green Camel is using waste of the Barramundi to grow organic plants.
  • Circular agriculture minimizes the use of natural resources and reduces waste.
"We grow over 130,000 kg kg of fresh leafy greens in an area of just 0.4 ha."

Growing in a ground-breaking way 

Johann Havenga, CEO: "Like a camel, we use water wisely, stick our necks out to do things differently and realize a sustainable journey is fundamental. Yields are generally lower in an organic farm and it’s more expensive to produce organically, with higher labor costs, more processes and so on.

“Through the development of ground-breaking technology, Green Camel has been able to produce organics at the same yield as conventional farming, managing certified organic horticulture and premium aquaculture (currently barramundi), without the waste or environmental risk experienced by conventional growers.

We produce the same yield as conventional horticulture, without the waste or environmental risk

Using every drop 
“Operating in an environment where water is becoming a precious commodity, Green Camel thrives. We use our water reservoirs to grow fish, then every single drop used in aquaculture is used to grow crops. It means every drop of water and every joule of sunshine is accountable. We are striving to deliver consistent organic produce within an industry that has traditionally been subject to substantial production variability.”

The Green Camel team currently grows a variety of organically certified leafy greens, tomatoes, cucumbers and barramundi. The innovative company has successfully developed the technology to build and operate industry-leading commercial organic glasshouses, with production at the same or better yields than conventional hydroponic glasshouse producers. CFO Sharon Markulin: “We want to be able to meet the evolving demands of consumers who are seeking highly quality, organic produce at a good price.”

Five focuses...

  • Increased & sustainable yields through symbiotic methodology and consistent delivery.
  • Increased & sustainable margins by targeting premium produce.
  • Less water, less labor, less energy and less antibiotics.
  • Zero effluent, zero runoff and zero farm waste.
  • Decreased risk with high tech management within a hyper-controlled environment.
