From Environmental Devastation to Economic Value
An aggressive weed threatening Australia’s agricultural future.
Prickly Acacia has been declared a weed of national significance. It has transformed vast areas of North Queensland’s pastoral lands into dense, thorny thickets, rendering them unworkable.
Originally introduced as shade cover for cattle, seeds are easily spread by livestock, waterways, and machinery. Once established, the plants release toxins that inhibit the growth of other vegetation, leading to soil erosion, biodiversity loss, and barren landscapes. Containment is virtually impossible without large-scale intervention.
Prickly Acacia has become a major threat to productivity, biodiversity, and native ecosystems.
23 million hectares of land has been degraded by prickly acacia.
175,000 seeds can be produced per tree each year, remaining viable for at least six years.
15% spread per year, threatening the beef industry and causing significant declines in land value.
$27.5 million in lost production annually for landowners.
Despite decades and millions of dollars invested in chemical and mechanical control, the infestation continues to expand. The cost to farmers, councils, and the environment is significant.
And the cost of inaction keeps growing. We need new thinking.
The solution isn’t eradication - it’s transformation.
Turning an invasive weed into clean energy and restoring land.
Nova BioEnergy’s solution is simple but powerful: harvest and process Prickly Acacia into torrefied biomass pellets to create a carbon-neutral, coal-alternative fuel for industrial use.
For every 100,000 tonnes of biomass processed, 4,000 hectares of infested land can be returned to productive native grasslands, the impact of which is vast.
Farmers and graziers gain back viable pasture, restoring value to their land. Native, protein rich grasses like Mitchell and Flinders will regenerate, which is beneficial for livestock, especially during periods of drought.
Native animals will return as native vegetation regenerates, reversing the damage caused by the invasive species and restoring balance.
Regional communities benefit from employment, revitalised economies, and Nova BioEnergy’s sponsorship of community events.
Australia reduces its reliance on unsustainable fuels through homegrown innovation, advancing towards a more resilient and sustainable energy future.
Global markets gain access to a sustainable, storable, and scalable fuel alternative for emissions-intensive industries that is in demand.
We’re not just solving a weed problem. We’re unlocking new value from degraded land, reducing emissions, strengthening rural economies, and positioning Australia as a pioneer in innovative climate-smart solutions.
