Transforming biosolids into a liquid fertiliser – the process
The process combines thermal, chemical and mechanical treatment to transform organic waste:
- Feedstock input and preparation
Biosolids and similar organic wastes from industrial, commercial and agricultural sources are prepared for treatment. - Physical-chemical hydrolysis
The material undergoes a patented process involving high-speed shearing, alkali addition and low-pressure steam injection which breaks down microbial cell walls and converts complex organic compounds into simpler, more accessible forms.
Product transformation
The result is a homogeneous, low-viscosity liquid with a relatively high solids content (around 13–16%), which remains fully pumpable using standard equipment.
The final product
The main product is a liquid fertiliser with balanced nutrients and organic matter:
- Macronutrients (NPK on dry matter basis): approximately 4.5 – 7 – 2.5
- Micronutrients: including sulphur, calcium, iron and magnesium
- Organic matter: supporting soil structure, water retention and microbial activity
The fertiliser meets recognised quality standards in United States and Canada markets.
