The com­plete solu­tion: Com­plete reject rejec­tion in two process steps

Stage 1: Pre-cleaning

At the begin­ning, the waste is crushed (con­di­tioned) and – if nec­es­sary – mixed with cir­cu­la­to­ry water to a medi­um dry sub­stance con­tent (TS con­tent) of 25.< Sub­se­quent­ly, a large part of the con­t­a­m­i­nants (~ 80) are sep­a­rat­ed in a hydraulic sep­a­ra­tion press. For max­i­mum sep­a­ra­tion, the con­t­a­m­i­nants are then heat­ed to more than 70 °C and pressed out once more. After that, the sev­ered con­t­a­m­i­nants have a TS con­tent of 50 and can be com­post­ed, dried or dis­posed of direct­ly for example.>

The sep­a­rat­ed liq­uid or pasty com­po­nents are heat­ed in a dou­ble tube heat exchang­er and san­i­tized in hold­ing tank (1 hour at 70 °C) and then – depend­ing on quan­ti­ties – dis­trib­uted to one or more digesters. In the digesters bio­gas is pro­duced from the fer­mentable parts, which is used to gen­er­ate elec­tric­i­ty and heat in a com­bined heat and pow­er plant.

Stage 2: Fine cleaning

The sec­ond stage of con­t­a­m­i­nant sep­a­ra­tion takes place con­tin­u­ous­ly direct­ly in the digester. Due to the biodegra­da­tion, solids such as frag­ments of glass, egg shells, bone chips etc. sed­i­ment on the digester bot­tom. The solids are dis­charged with a floor scraper from there. Float­ing sub­stances such as plas­tic pieces, cork residues or the like are detect­ed by a skim­mer and dis­charged from the digester. This pre­vents the accu­mu­la­tion of con­t­a­m­i­nants in the digester and thus ensures their func­tion in the long term.

The remain­ing fer­men­ta­tion residue can be used as a liq­uid fer­til­iz­er. Alter­na­tive­ly, it may be sub­ject­ed to sol­id-liq­uid sep­a­ra­tion where­in the sol­id is post-com­post­ed and mar­ketable as a com­post. The cen­trate water can be fur­ther puri­fied by means of a water treat­ment (eg SBR waste­water treat­ment plant).
