Christiaens’ Over Head Filling (OHF) system is an automated system to fill composting tunnels in horizontal layers which makes a perfectly even and maximum airy pile of input material. “Difficult” to compost materials which have poor porosity and permeability will compost easier and quicker compared to bucket loader fillings.
Each fill is reproduceable resulting in a constant compost quality.
Also materials can be stacked up higher into a tunnel, depending on the bulkdensity and structure of the material, resulting in a higher plantcapacity.
