Phase III Compost
The Industry Standard for Yield and Consistency
Our Phase III Compost is the flagship product of CNC Substrates, produced at our large-scale facilities in Milsbeek and Moerdijk as well as in our two facilities located in Poland.
By delivering substrate that is already fully colonized with spawn (spawn-run), we allow growers to shorten their production cycle significantly and reduce the risks associated with the early vegetative phases.
Product Specifications
Consistent Quality at Scale Based on our IVC® process, our Phase III compost benefits from unmatched economies of scale and specialist process control.
- Incubated
The compost is fully spawn-run in our tunnels, meaning the mycelium has already colonized the substrate.
It is ready for immediate casing upon arrival. - Varieties
We offer a wide range of spawn species for both White and Chestnut/Brown mushrooms. - Customization
Customer-specific supplements can be added during the filling process to boost yield potential. - Organic
Certified EKO/Organic varieties are available on request.
Logistics & Delivery
Industrial Supply Chain Integration
For the large-scale European grower, substrate quality is only half the equation; the other half is logistical precision.
Operating on a strict filling schedule requires a partner who treats delivery with the same scientific rigor as production.
Hygiene First
Our trailers are dedicated exclusively to mushroom compost.
They undergo rigorous CIP (Clean-In-Place) cleaning between loads to prevent cross-contamination.
Rapid Discharge
Our walking floor systems allow for the unloading of 30+ tons of substrate in under 20 minutes, minimizing exposure to ambient air.
The “Walking Floor” Standard
We utilize one of the largest dedicated substrate fleets in Europe to ensure our Phase III compost arrives with its biological integrity preserved.
Thermal Stability
Our logistics fleet is engineered to maintain the biological stability of your substrate throughout the journey.
Our walking floor trailers are fully insulated and designed for efficient, precise unloading at your facility.
To ensure a controlled environment during transit, the substrate can be actively cooled before delivery, arresting premature heat generation and preserving the energy of the mycelium.
Serving customers throughout Europe, we maintain a consistent climate-controlled process that protects the quality of the compost from our facility to your farm, ensuring it arrives in optimal condition for immediate production.
Service Options
Joint Filling & Covering as a Service — JFC
We offer a complete filling service using our own machinery to fill compost and casing soil simultaneously (Simultaneous Filling and Covering).
This ensures maximum hygiene and speed and high productivity.
We deliver in bulk 6 days a week (Monday – Saturday).
Whether you are filling tunnels in Poland or shelves in France, our logistics planning team integrates directly with your production schedule (Just-in-Time) to ensure a continuous flow without bottlenecks.
