Diverts green waste from landfill
Aquatic vegetation cleared from Australian waterways is normally dumped or sent to landfill. PhragMighty captures it as a productive feedstock.
Flagship Product · ™
Mighty green · Mighty good
A liquid biostimulant and high-carbon biopellet, both made from harvested Phragmites reeds — turning an invasive aquatic plant into productive inputs for Australian growers.
The Problem · Eutrophication
Too much of a good thing is choking our waterways.
Excess nitrogen and phosphorus from agricultural runoff trigger eutrophication: a runaway cascade that turns clear water into algal soup.
Fig. 01 — Algal bloom
- 01
Algae feed on excess nitrogen and phosphorus in the water.
- 02
Algae blooms — growing, spreading and forming dense mats.
- 03
Water turns green, develops odours, and biodiversity collapses.
- 04
Sunlight is blocked. In some cases, toxins are released.
Aquatic macrophytes like the common reed (Phragmites australis) and Cumbungi thrive in these conditions, dominating affected waterways. They grow 3–5 metres per season, spreading laterally through underground roots, and release allelopathic chemicals that suppress other vegetation — collapsing biodiversity and bird habitat.
Case Study · Lake Wyangan
One catchment, seventy years apart.
Lake Wyangan, near Griffith NSW, is a textbook eutrophication case. Decades of agricultural runoff have shifted it from a clear recreational lake to a recurring algal bloom hotspot.

Our Solution
A microbial process that turns waste into working inputs.
Tasked with controlling an invasive aquatic plant, we knew there was a better path than landfill. Through theoretical and applied research, we developed a microbial process that converts harvested reed biomass into two beneficial products: a liquid biostimulant and high-carbon biopellets.
We named it — from the botanical name for the common reed, Phragmites australis. It is mighty green, and it is mighty good.

Benefits
What it does for you — and the environment.
contains trace elements, beneficial microbes, and complex carbon. Independently lab-tested for both nutrient and contaminant levels.
/ 02
Reduces methane emissions
Diverting carbon-rich green waste from anaerobic landfill decay reduces methane emissions and closes the nutrient loop on-farm.
/ 03
Boosts root, shoot and resilience
Independent trials show increased root and shoot mass, improved drought resistance and reduced disease pressure compared with controls.
/ 04
Improves waterway health
Every tonne harvested is nitrogen and phosphorus removed at source — directly contributing to healthier inland waterways.
The Range
Two formats. One feedstock.
The range gives growers two ways to deliver carbon, microbes and trace elements to their soil.
PRD-001 · Liquid
Liquid Biostimulant
Trace elements, microbes & carbon — in solution.
Independently lab-tested for nutrient and contaminant levels, and plant-tested on tomatoes, citrus, ornamentals and turf grasses. Plants treated with PhragMighty showed greater drought and disease resistance and increased root and shoot mass compared with controls.

PRD-002 · Pellet
High-carbon Biopellets
Slow-release carbon for soil structure & biology.
Adds complex carbons, supports beneficial microbes, improves drainage and nutrient buffering, and reduces soil surface temperature. Best applied at the start of the growing season, or whenever soil organic matter is low.
