Biological waste

Organic waste

Our shredders process biological and biogenic waste to generate an optimal substrate for further utilisation in your biogas plant or in your disposal business. The application area ranges from green or garden waste to food waste and expired goods including packaging to slaughterhouse waste.

Non-homogeneous or organic waste in pieces including packaging must be shredded to prepare it optimally for fermentation. Our low-speed S-series shredders are ideally suited for this application. These two-shaft shredders ensure reliable processing and guarantee a pumpable fermentation substrate. Thanks to the special equipment, efficient cutting unit and sturdy machine construction, these shredders are very reliable and have a long service life!

Applications

Goods whose “best-by” date has passed are usually destroyed. A shredder that is specially designed for this application is required to do this efficiently and reliably. The UNTHA 4-shaft technology provides the ideal solution to separate foodstuffs from their packaging. The downstream separation technology then easily removes the packaging.

Organic waste needs to be shredded to best prepare it for fermentation. Our low-speed RS shredder is the ideal solution. It reliably and efficiently prepares the organic waste, thereby guaranteeing a pumpable fermentation substrate. 

Waste from restaurants and catering companies is often used for the production of bio-gas. Our tested and proven shredders are often used in this process. We offer reliable shredding machines for processing restaurant and catering waste that can be adjusted specifically to your needs.

Slaughterhouse waste, by-products, and animal carcasses of poultry, pig and cattle fattening are often processed to meat-and-bone meal and fat. Our sturdy shredders have special seals and have no trouble processing bones. We also offer additional equipment versions and are able to optimize the shredding machine to your requirements. 

Green waste is shredded in the first step of the humus production process. Our shredding machines easily deal with branches, bushes, small tree trunks, and garden waste. We offer shredding systems specifically designed for your application.
