Organic Fertiliser Systems
Designed around the resource.
Scoped around the objective.
Digestate is a resource stream containing nutrients. Its use as fertiliser or soil conditioner depends on feedstock, product analysis, processing requirements and intended application.

THE PROCESS
How does the system work?
01
Characterisation
Analysis of dry matter, nutrients, salinity and product safety parameters.
02
Solid–liquid separation
Mechanical separation of fractions according to the intended use.
03
Processing & preparation
Stabilisation, composting, drying or advanced liquid treatment where needed.
04
Storage & use
Storage, transport and agricultural application planning suited to product characteristics.
SYSTEM SCOPE
Engineering components
considered together.
Equipment and process options are selected according to project inputs and target outputs.
Solid product line
Assessment of composting, drying and packaging options for the target product.
Liquid fraction
Storage, filtration and advanced processing options according to the intended use.
Nutrient management
Nutrient recovery through analysis, mass balance and application planning.
THE STARTING POINT FOR DESIGN
What data does your project need?
| Input | Digestate flow, solids and source feedstocks |
|---|---|
| Analysis | N, P, K, pH, conductivity and suitability parameters |
| Product objective | Solid product, liquid product or on-site agricultural use |
| Logistics | Storage duration, transport distance and seasonal demand |
Product characteristics and use depend on analysis; the processing line is designed around the target product.
FREQUENTLY ASKED QUESTIONS
Key points before making a decision.
Is digestate automatically a market-ready fertiliser?
Not all digestate can automatically be marketed as a fertiliser. Product classification, analysis, processing needs and applicable suitability requirements must be determined separately.
Can liquid digestate be used directly in soilless cultivation?
Suitability is not assumed. Salinity, nutrient balance, suspended solids and hygiene must be assessed; treatment and controlled trials may be required.
