5 Structure and function
5.1 Function
The BioMaster®serves as the infeed station in the system. The system offers an
economically and ecologically sensible, hygienic solution for recycling kitchen waste
and food waste. The system is used in commercial kitchens, canteens, hotels, food
service and communal catering. The BioMaster®converts the waste produced into a
homogenous biomass.
Kitchen waste and food waste are fed into the loading chute of the BioMaster®and
homogenised in the BioMaster®using the water contained in the waste and adding
process water.
Additional water can be fed in via a cleaning nozzle to cleaning the loading chute
and to process extremely dry or very light waste.
The resulting biomass is pumped out of the BioMaster®and transported via a closed
pipe system to the storage tank.
When using the BioMaster® as an infeed station of a vacuum plant, the biomass is
conveyed through the pipe system by means of vacuum.

It has been optimally adjusted to your individual operating conditions.
If the water supply is too low, there is an increased risk of clogging in the Bio-
Master®and in the system.
The homogenisation technology enables the efficient conversion of food waste into
pulpy biomass with simultaneous volume reduction.
By using the waste's own water, the addition of process water can be kept as low as
possible.
The required amount of water to add depends largely on the type of food waste and
the length of the transport and extraction pipe. MEIKO GREEN Waste Solutions
GmbH adjusts the settings to the individual customer requirements during commis-
sioning. Settings can be readjusted during maintenance if necessary.
