Mixed waste treatment plant MBT

In an MBT(mechanical-biological treatment)-plant mixed waste streams are treated by mechanical means such as shredding, screening and separation, as well as by biological processes. Start With shredding Process starts with a Terminator shredder, with shredding performance configured for the input material. The goal of this step is to homogenize the input stream, and open up bags and packages. The contrary resistance of the shredder lets it take in a wide range of input materials, while the even feed ensures a consistent supply of shredded material to the downstream process steps. Separation of organics Since the largest organic content is in the fine fraction, screening is the first step after shredding. The resulting organic fraction is sent to biological preparation. The machine used is either a stationary Komptech drum screen or the Flowerdisc disc screen. Further recycling steps The oversize fraction is put through screening and separating to generate various kinds of RDF and recycling fractions. Biological tratment The organic fraction is piled into triangular windrows bywheel loader. Regular turning with a Topturn compost turner supplies the process with air and water if necessary. This accelerates composting. The windrowtechnique can be supplemented by a closed composting tunnel or anaerobic digestion technologies. Final compost treatment To produce compost, the material can be cleaned after the rot- ting phase using a stationary or mobile screening and separation technologies. The screen overflow is cleared of contraries using wind sifters.
