  Systems          Description

  Food waste       When considering separation of organic food waste, the handling and potential for volume reduction should also be considered.
  separation       As an example, the Pulpmaster system can be used to reduce the stored volume of food waste produced, and to prepare the material for re-use. Typically, the
  and              system is placed in proximity to sink areas in the kitchen, particularly where food preparation waste or plate scrapings can be easily disposed. This provides a
  collection       fully sealed transfer system for storage and collection. Pulping systems can also be placed back-of-house spaces for restaurants and cafes or placed within a
                   refuse room for centralisation to multiple users. Pulped food waste is pumped into holding tanks for storage and collection via a 50mm pipe and collected by a
                   liquid vacuum tanker.
                   The images below provide visual context of the connection from pulping machine to storage tank and the option for decanting 120L bins into the machine via a
                   bin lifter and auger feed. The tank may be up to 20m away from the pulping machine. The distance is increased when including vertical drops from upper levels
                   of the building. The storage tank may be up to 30m from a loading area. Collections are completed by a vacuum tanker which may range in size depending on
                   the size of the storage tanks and the distance of the tank from the loading area.

  Waste            Converting waste by reducing its volume and weight means less material to be disposed of, which results in fewer refuse collection vehicle kilometres. This
  Conversion       allows cost savings in logistics and has a positive environmental effect due to less fuel used per amount of waste to be disposed.
                   As an example, OMPECO provide a solution for converting general and medical waste into a sterilised, dehydrated ground material as shown below. The
                   process involves loading the sterilisation chamber with waste material and crushing / shredding of the material by rotors to produce a fine ground. During the
                   process, the material is heated by friction to 100˚C which causes the moisture in the waste material to evaporate. After evaporation, the material is heated
                   further to sterilisation or pasteurisation. The ground material is then cooled down to be unloaded from the converter. The final product has excellent long-
                   term handling and storage properties, the it has up to 80% less volume and 50% less weight than the original waste material. It can be used in waste to energy
                   systems as it is comparatively dry with a high calorific value.
