Organic waste Organic waste is shredded for a wide variety of reasons. For example, garden waste and tree loppings are primarily used to make compost and biogas. A high through-put is particularly desirable in these applications. Animals which have been slaughtered because they are diseased (e.g. cattle affected by BSE) must be removed and incinerated in order to reduce risks to the health of both man and other animals. UNTHA four-shaft shredders are particularly useful for this application, shredding this type of organic material reliably and safely. Out-of-date goods can be safely and reliably removed from the supply chain by shredding the packaging and contents together. This is particularly important in the case of damaged or contaminated food stuffs.
Cutters specially designed for the UNTHA four-shaft RS40 series shredder allow high through-put rates of garden waste for compost and biogas production. The "pumpability" of the shredded materials is critical for process security in the later production stages. Special tooth geometry and cutting clearance are necessary to obtain the optimum granule size.
