Waste processing

Our shredders are well suited for a 1-step or 2-step waste recycling.

A mechanical-biological waste recycling is usually performed when processing household or commercial waste similar to household waste. The goal of this treatment is to generate a landfill-suited waste material by separating waste fractions with a high calorific value, valuable resources as well as foreign objects.

We understand the tough requirements that the shredding technology of a mechanical-biological waste recycling system faces. With our newly engineered XR series we are able to offer the ideal product that meets these tough requirements for both low operating costs and high availability.

 

Overview of the different technologies for mechanical-biological waste processing

  • Mechanical-biological waste treatment: In this process, the waste is mechanically separated from the metals and the fractions with high calorific value are sifted out. The subsequent biological treatment occurs in the form of a decomposition or fermentation process. The end product can be deposited in a landfill due to its low biological activity.
     
  • Mechanical-biological stabilisation: The mechanical-biological stabilisation is different from the mechanical-biological waste treatment because in addition to the biological treatment, the fractions with a high calorific value are recycled into substitute fuels.
     
  • Mechanical-physical stabilisation: This process generates substitute fuel through a mechanical and physical sorting process (e.g.: separation of materials containing iron from materials not containing iron) using a multi-phase recycling process. The substitute fuel is usually processed into pellets or fluff.

Applications

Household waste is characterized in particular by organic components and a high content of particulate matter. With our XR pre-shredders and TR post-shredders we are able to offer a very efficient shredding system for a 2-phase household waste processing.

The economic processing of industrial and commercial waste in just one phase: All thanks to the new XR series!

The XR series cutting unit and hopper shape are designed to handle shredding bulky waste. The cutting unit's high resistance to foreign objects and the ability to easily remove foreign objects via the service hatch make this shredding machine particularly efficient for shredding bulky waste.

With our XR and TR shredding machines, we offer reliable systems for processing compressed plastic bales to generate substitute fuel. Depending on the application case, we offer a 1-phase or 2-phase plastic waste processing.

Our machines are impressive at shredding scrap wood (e.g. demolition wood and construction timber) most notably thanks to the high-quality output material with reduced fine particulate matter combined with a high throughput rate.

The XR pre-shredder facilitates the economic processing of mixed construction waste. The shredding machine is highly resistant to the mineral components in the waste.
