• Continuous process for compatibility with waste
  arisings

NB - What mixture MUST I use?
High Nitrogen Waste e.g. Food waste
including Meat Fish Vegetables Fruit NB. When
wet food waste is used we recommend using a
dewatering system to remove excess water to
achieve 60-65 moisture.
High Carbon Waste e.g.Wood Pellets Chipped wood
waste Wood chip from trees Waste / broken
pallets NB. Chipped wood provides a better
structure than shredded wood or wood shavings,
but shavings and sawdust can be used in small
amounts to alter moisture levels.
or

e.g. 11 (by vol.) ratio of food waste wood
chip (30-351 CN ratio, 60 65 moisture Level)
CAN NOT COMPOST PLASTIC, METAL, GLASS

How the IVCss Systems Work
Fresh damp waste 60 65 water
Water vapour and CO2 are produced by the
composting bacteria throughout the process and
they are vented to atmosphere or further
treatment if required.
Getting dryer throughout process
Excess water is drained to a sump for re-use or
disposal after further treatment.
Maturation zone
Hygienisation zone
Dry product goes to maturation area for 4 - 8
wks.
Exiting product 40 - 45 water
Heated area
Temperature Probes
