Digestate turned into quality compost
Once the fermentation process is finished, each fermenter is fully emptied by a wheel loader. The BEKON process generates a dry fermentation residue which means that it is not necessary to separate or press the digestate allowing further compost processing. Part of the material is used for inoculating new biomass and is returned to the cycle.
BEKON has developed an enclosed tunnel composting process for treating the dry fermentation residue. The exhaust air emitted by tunnel composting is cleaned using a biofilter, thus avoiding the emission of odours.
The final composting stage generally takes the form of windrow composting. The final compost is a valuable organic quality fertiliser used in agriculture and gardening, possibly generating additional revenue.
