AMCO, the Circular Supply Chain
The Origin of Excellence
High-quality Agaricus production doesn’t start in the tunnel – it starts at the stable.
At the CNC Substrates Centre of Excellence, we believe that the integrity of the final harvest
is inextricably linked to the purity of t he raw materials.
To ensure the world’s most reliable Agaricus substrate, we operate a dedicated subsidiary,
AMCO (Algemene MestCentrale Ottersum), the European leader in specialized organic resource management.
From Stable to Table
Sustainability is the engine of our production model.
Through AMCO, we transform agricultural by-products into premium food-growing media, sitting at the very heart of the circular economy.
The Foundation — Premium Horse Manure
For Agaricus cultivation, consistency is the currency of success.
Whether you grow White Button mushrooms (Agaricus bisporus) or Chestnut/Portobello varieties (Agaricus bisporus brown), the foundation of your crop is the substrate.
We offer two distinct product lines – Conventional and Organic – both manufactured with the same rigorous attention to detail and process control.
Great compost starts with great raw materials.
Our Agaricus substrates are based on high-quality horse manure supplied exclusively by our sister company, AMCO.
This vertical integration guarantees a consistent, straw-rich input stream, year-round, eliminating the variability that plagues other suppliers.
A Legacy of Reliability (Since 1971)
Founded in 1971, AMCO has grown into the largest operation of its kind in Europe.
By maintaining a massive, high-integrity network of suppliers, we ensure that CNC Substrates has a consistent, year-round flow of the straw-rich horse manure required for elite Phase III substrate.
The Network
Over 2,000 partners, across the Netherlands, Belgium, and Germany.
The Sources
We work with professional riding schools, racing stables, leading stud farms, and racecourses, focusing on equestrian properties with 15 horses or more.
The Quality Standard
We specifically collect straw-rich manure, selected for the structural and nutritional properties essential for optimal fungal thermogenesis.
Why AMCO Matters to Our Growers
For a mushroom grower, the “AMCO Advantage” translates directly into biosecurity and consistency.
- Traceability
Because we manage the collection ourselves, we have unparalleled insight into the origin and quality of our primary raw materials. - Environmental Stewardship
Our “Cradle-to-Cradle” philosophy ensures that nitrogen-rich organic matter is diverted from waste streams and
upcycled into the global food chain. - Scale & Security
In an era of supply chain volatility, AMCO provides CNC – and by extension, our customers – with a secured, localized,
and resilient source of energy for Agaricus cultivation.
