Shredding for AD

Aerobic and anaerobic digestion processes form a key part of the world's evolving bioenergy infrastructure, and it is no secret that the resource potential of organic substances is optimized if the ‘waste’ is homogenized before it reaches the digestion technology. Shredding for AD is therefore one of the most important pre-treatment processes to take place, before innovative bacteria and stimulants can get to work to produce a biofuel.

  • What to look for in a shredder for aerobic or anaerobic digestion

    Shredding helps to liberate organic materials so that the onward digestion process can unfold. The technology can therefore be used to open cornstarch bags, separate food from packaging, and volume reduce the ‘waste’ so that it can be further treated.

  • What to look for in a shredder for aerobic or anaerobic digestion

    The contents of organic waste streams can never be guaranteed, so foreign object detection systems within the shredders should be sought, to help extract ‘unshreddable’ contaminants like silverware, from the material. This contributes to a better-quality shred, with no unplanned operational disruption.

  • What to look for in a shredder for aerobic or anaerobic digestion

    Organic waste is typically a corrosive substance, so an application-specific cutter and sealing system will protect the components of the shredder from harmful material ingress. Evidence of low wear, easy maintenance, high uptime and proven throughput levels will also reduce the whole life running costs of the machine.

  • What to look for in a shredder for aerobic or anaerobic digestion

    Particle homogeneity is crucial for optimum downstream treatment. Configurable shredding technology – with the added help of screens if required – help to achieve a defined output fraction.
